1971 FORD 3000 TRACTOR

SERIOUS ENGINE WORK

The 3000 was supposed to take over most of the chores, but has non gotten much use since I bought it. The engine has been making besides much noise for me to get comfortable working it very hard or very much. As seen in this photo the 2N and 8N have continued to exist my workers. The solution is to pull the 3000 apart, figure out what it needs, and either set up it or office it out.

It took a few weekends to clear a spot in the shed to do engine piece of work. The V8 projection is almost gear up for a test bulldoze. The but thing holding that upward is the endless list of other things that need fixin'.

The 3000 is parked at the shed. Wish I had room to get it completely inside to do the split, but that own't happenin' any time soon. It volition be supported under the tranny, with both rear tires chocked forepart and back. There is an incentive to work fast. The hood, cowl, radiator, and front end beam have to come off before the doors will close on the shed.

MODIFIED FRONT SPLIT

Major repairs should never exist attempted without referring to a service manual. Long before starting to turn wrenches, read thru the entire process more in one case. Become comfortable with the steps required. If at that place is any question regarding any part of the piece of work, enquiry that separately. Make sure whatever special tools needed are available or perhaps aren't actually needed. In this instance, some of the special tools mentioned in the manual have not been bachelor for many years. Creative solutions may be required.

The Ford Tractor Service Manual shows a typical forepart split (engine/tranny) and a rear split (tranny/unequal). This volition be a modified front divide. It looks like the merely reason to always exercise a forepart split (the manner it is shown in the manual) is if the simply affair needing service is the clutch/flywheel. It should be much easier to remove those large bolts in the front axle carrier while the tractor is by and large in one piece. Removing pieces one-at-a-fourth dimension makes information technology easier to clean and decide what needs repair, replacement, or just cleaning and painting.

Completely drain cooling system and engine oil.

TIP:
Unless you have already worked on tractors larger than the North-Series, more (bigger) tools are probably going to be required:
1 - A four-foot piece of 1-i/ii" heavy wall pipage. This volition be an extension handle for your breaker bar.
2 - Large sockets and combination wrenches in sizes from 15/16" to ane-i/4".
3 - If your socket set is too small-scale or will not survive using a 4-foot handle, get some skilful quality 3/four" drive sockets.
4 - A high-torque impact wrench and impact sockets to 1-1/iv".
5 - An engine hoist or overhead winch.
6 - Engine stand up rated 1500 pounds, with brackets that will reach the mounting holes on this engine. Even better is an adapter that mounts to holes at front and dorsum of one side of the engine. With 1 side of the engine close to the mail, the engine stand will be much more stable. I've seen several examples on-line. It would have been better to exercise that than buying the adapters I used.

Hardware and minor parts:

All nuts, bolts, and small parts should be inspected, sorted, and stored as they are removed. Identify damaged fasteners and parts that will demand to exist replaced. Take pictures of everything every bit information technology is taken autonomously. Plastic containers in diverse sizes piece of work not bad. Get at to the lowest degree ane platic box with dividers that tin be rearranged to provide individual bins of diverse sizes. If the larger containers have screw-on lids, the lid can be attached nether a shelf or workbench to go along them off the floor. Switch to a new container, when switching to a new sub-assembly. While other piece of work continues, buy and store new hardware matched-up with the broken/rusty stuff that came off.

Plan on every step of this job taking longer than expected. In this case, both front end radius rod bolts were completely frozen where they went thru the axle. The bolts holding the outer axles to the center section were very hard to remove. All of the hardware on this tractor is at least an gild of magnitude larger than anything on the N-Tractors. My HF 3/4" drive socket set did non survive the more intensive use.

Radiator:

The radiator is attached with two convict carriage bolts (just similar the N-Tractor radiator). Unfortunately (merely like the N-Tractors) the bolts were completely rusty, and only loosened about 1/two plough earlier spinning. I wedged a pry-bar to try and hold the foursquare in the slot. That only got some other half-plough or so. That was just loose enough to get a sawsall blade in there. Add together new radiator bolts and safety pads to the list of parts needed. The radiator looks great from the front. Information technology should, I spent virtually an hour cleaning and straightening fins when I got this tractor. Unfortunately, the dorsum side has a deep circle where a fan blade cutting into it. Surprise! Someone tried to solder the radiator tubes. I've never seen that work very well. This one has been leaking. Add together re-core radiator to the list.

Ofttimes check the support under the tractor. Cinder blocks are useless, wooden timbers are better, a jack stand is best. This driveway area is packed similar concrete, but even hard packed gravel is not a completely stable surface. We take been having lots of rain, so information technology may have loosened the dirt and gravel. There used to be a 12" square piece of 1/iv" steel plate around hither that could be tossed under a jack stand. That was MIA, and so my large floor jack was used to back-up the jack stand.

Minor Deviations and Additions to the Service Manual:

Pre-clean everything as areas go accessible. Keeping an air hose handy to blow clay and droppings away helps continue that stuff from getting within the engine. The steering drag links were taken loose at the forepart, then swung upwards and over to lay on the rear axle. Radius rods were completely removed. The front tires and outer axle assemblies were unbolted from the middle section. And then the axle carrier was unbolted from the front end of the engine.

Unbolting the axle carrier was not easy. Darn glad I did not practise the split, and then try to accept this autonomously. The forepart axle support is very similar to the same office on the N-tractors, only a lot heavier. It is attached to the engine with four big basics and bolts. These were not rusty, only must have been tightened to about a million foot-pounds. All the bolts on this tractor are laughing at my ane/2" drive touch wrench. Fifty-fifty at 110 psi it falls style brusque of having enough torque to break this stuff loose. A four-foot piece of piping on a breaker bar should accept worked, simply the first attempt completely destroyed my HF 3/4" drive, six-point, 1-1/8" socket. I've occasionally managed to cleft smaller sockets, this ane exploded.

The merely other ane-1/viii" socket in my tool chest was the old Craftsman thin-wall, 12-point, 1/two" drive, that was being used to concord the bolt when the HF socket exploded. The neighbor saw me scratching my caput, and came over to encounter what I was up to. He went back and returned with a 1-ane/8" box end wrench. We both expected the thinner 12-point socket to fail. But to prove me wrong, all four nuts came loose without breaking anything. The beam pivot bushing is loose and needs to be rebuilt. Add that to the list. Breaking one socket is all the excuse needed to purchase some improve quality sockets. The engine should have been on the stand past now. At least removing the beam support was enough to permit the shop doors to close.

Engine Accessories:

It may announced that there are just a few things left before the engine tin can be pulled. That is misleading. Those few things continued to have more fourth dimension and effort than expected. In order to forestall damage, always remove wiring, carbeuretor, and fuel lines before removing an engine. The fuel lines on this tractor are a nightmare. Tank to fuel pump is threaded thru everything from the back to the front of the engine. Fuel pump to fuel filter is worse. That ane apparently has to be laid in identify as the manifold is bolted on. Using flare-nut type wrenches on every hex nut volition usually allow fuel lines to be removed without dissentious the tubing or fittings. These came off in expert shape. They can be cleaned-up painted, and re-used. Pocket-sized bolts that support the rear hood and fuel tank have loose nuts on the back. Fishing a 1/2" wrench in in that location to hold those nuts was fun. The larger bolts that secure the battery tray assembly to the dorsum of the engine were difficult to remove.

Hydraulic Pump:

This tractor does non have anything like the "external hydraulic manifold" described in the service manual. Remove four bolts that adhere the hydraulic pump to the engine. Remove one clamp subclass that holds i hydraulic pipe to the top of the manual. This allows the pump to be pulled up and tied out of the fashion. This should provide just enough room to become a socket on the two top bolts attaching the engine to the manual. For some reason, these are a larger size than the hardware used for the four engine-to-transmission basics and bolts. Interruption them loose, then switch to a wrench before the socket becomes trapped.

Set-Up Engine Crane:

Finally, it is time to get the elevator in place and attach it to the engine. Equally the engine-to-manual bolts are loosened, check that the engine weight is supported, level, and not twisting. Remove the nuts and any washers. Get out the bolts in place. Pry the engine forward about 1/2" to release the dowel pins that align the engine and transmission. Make certain the engine-to-transmission bolts stay loose in the holes. Correct any misalignment between teh engine and transmission. Keeping the bolts in place, helps guide the clutches directly-off the manual input shaft without bounden. Pulling the engine is not nearly equally hard equally aligning those splines on the way back together.

Engine Ready to go on the Stand:

The engine is off, and in the store. This "little" 3-cylinder is very heavy. I've installed consummate automotive V8 engine/transmission assemblies that did non counterbalance equally much as this engine. The double-clutch associates and flywheel will have to be removed. The shop manual mentions several special clutch tools that I could not observe decent pictures of. Browsing the various forums on-line I was able to verify that the clutch release levers tin be tied downward with safety wire. Then the clutch assembly can be unbolted from the flywheel. Every bit long as the assembly does non need to be serviced, no special tools are needed. All I volition need is a pilot alignment tool to reassemble the clutch on the flywheel.

Rubber wire looped thru the clutch assembly and over each release lever worked fine. Pull the wire tight on each lever earlier moving to the side by side 1. Then run some other piece of wire in the opposite management. One is good, two is insurance. Lower the engine and put wooden blocks under the corners before removing clutch assembly bolts. Find some way to support the clutch assembly while it is existence removed. Same for the flywheel. You practise not want the clutch or flywheel to smash your human foot. After removing the clutch and flywheel it occurred to me that there needs to be a programme for reinstalling those. Information technology was all I could do to wrestle them safely to the floor. Check the starter and band gear teeth. If they await bad, at present is the time to replace those. Mine looked mostly good. At that place is one place nearly 3" long where the teeth have been chewed a little. Small damage can be fixed with a file or small grinder.

Problem: Four v/viii" Grade 5 bolts the correct length were set up bated, ready to bolt this engine to my stand up. I even fabricated certain the five/8" bolts would fit thru the brackets on my engine stand up. Unfortunately the brackets on my "universal" engine stand would non spread wide plenty to line up with the holes in this engine. They are about ane/2" short. My other engine stand is much lighter, but the engine plate and brackets are made to exactly the aforementioned dimensions. None of the brackets I have will match upwardly to this engine. Bummer.

These engine stand up adapters came from Merrick. They are made longer than the brackets that came with my engine stands, but they only accept ane/2" hardware. A set up of grade v bolts, 5-1/2" long were used to adhere the engine to the stand. Attempt to become the engine mounted low enough on the stand that information technology volition be mostly balanced when turned over. This engine was mounted as low as information technology would go, and was still way likewise top-heavy. The cylinder head will have to come up off earlier trying to rotate information technology. This little iii-cylinder is a very heavy casting with thick webbing. The engine crane will remain hooked to the cylinder head, to provide some support.

FINALLY - ENGINE DISASSEMBLY:

Follow the instructions in the transmission, and take lots of pictures. Go on sorting/labeling hardware every bit it comes off. Rotate engine to Top-Dead-Eye on No.i (front) cylinder. Remove distributor cap, and mark location of rotor on benefactor housing, mark position of distributor on engine. Take more photos. Pay careful attention to where the vacuum advance is located. I didn't, and had to reinstall the benefactor twice to make room for the carb.

The rocker arm associates is secured in place by head bolts. Remove the entire rack assembly with the associated head bolts still in place. The manual says the bolts hold the thing together. I'm non planning to detach it. Prepare the whole thing on the workbench, and comprehend it with a rag. Each pushrod and lifter must go dorsum in the hole it came out of. Find a way to mark and store them and so they won't get mixed-up. One time the rest of the head bolts are out, and the caput has been broken loose from the block, the engine crane tin do the heavy lifting to become the cylinder caput off and set aside. That removes enough weight the engine can now be rotated on the stand. It is nevertheless top-heavy, but non also bad. The first thing I meet is the No.i piston appears to be laying to one side of the diameter.

Rocking the crank dorsum and forth shows that all pistons are very loose and actually rocking in the cylinders! This explains the noisy engine. There is very little ridge at the top of the cylinders. A deep ridge would have to be removed with a ridge reamer earlier the pistons could exist pulled out. Turn engine upside down, remove rod caps, protect journals from impairment, and carefully pull each piston/rod associates out. The pistons volition not be re-used, merely annotation which way any markings were pointed earlier they came out. The rods and rod caps need to be marked/stored, and so they become back to the same cylinder they came out of. If the bearings, journals, and clearances are in good shape, the bearings tin be re-used. Verify that the rod caps were fitted together with the tangs for the bearing shells on the same side. Each rod and cap should already be stamped with the cylinder number they came out of. Make a note of which manner these stamps were pointing, so they can be reinstalled the same mode.

These piston/rod assemblies were so big and heavy, I couldn't resist grabbing one of the N-Tractor pistons to compare. These pistons are weird. The earlier photograph shows how the combustion chamber is recessed in the summit of the piston.

The cylinder walls wait so bad information technology is difficult to believe this engine could make enough pinch to run as well as information technology did. A dial-type cylinder bore gauge was used to mensurate front-to-dorsum, and side-to-side bore at meridian, heart, and bottom of each cylinder. Good News! The cylinders can still be honed to spec for 0.040" oversize pistons. That is the largest oversize piston made for this engine. If the harm in No.1 cylinder had been any worse, this engine would accept to go to a machine shop to have sleeves installed. The pistons are desperately scuffed and worn, just may yet be useful to someone. New pistons for this engine are around $150 each.

Normal practise for most people would be to have the cake to a motorcar store, and permit them do the remainder of the disassembly. A practiced engine shop has all the proper tools and expertice to check for hidden issues, and properly practise any piece of work necessary. This work is not inexpensive, just worth every nickel for anyone who has not washed that type of work. Nobody has ever accused me of being normal. Engine piece of work is fun, and when I exercise the work myself, there is no question the work is washed right.

CYLINDER HONING:

Delight don't misunderstand, any engine shop should have ameliorate measuring tools, automated equipment, and the experience to practise precision engine work the style it should be done. Machine shop prices are normally very reasonable for the precision work they exercise. Most engines being rebuilt will have suffered some sort of major failure. The engine may accept been run hot. The engine may not have been running for many years. Anything that creates whatsoever question near the integrity of the block must exist checked-out by a machine shop. They know how and where to check for cracks and other problems. Make sure you are dealing with a good shop that does enough business to have skilful quality equipment and (most importantly) good people.

There is no mystery about the condition of this engine. It was running well, not overheating, just very noisy. Subsequently studying the innards, this engine only needs to be fitted with oversize pistons. The specifications for this tractor engine are looser than nearly of the motorcar engines I've worked on. The cylinder specifications are well inside the capability of a expert rigid cylinder hone. A rigid cylinder hone has a rigid parallel frame for the stones, and a very fine adjustment knob. A cheap, spring-loaded brake hone is worse than useless for honing engine cylinders. If y'all want to do more of your engine piece of work at domicile, and have the power to do precision piece of work, 2 rigid cylinder hones that piece of work well are the Sunnen AN-112 and the Lisle 15000. These hones are specifically designed to right cylinder wear issues like taper, barrel, scoring, and out-of-circular. With the right person running them, these hones are accurate to within one-half thousandth of an inch (0.0005").

Warning - A hand-held hone cannot fix a cylinder mis-alignment that was originally bored wrong by the factory. Correcting factory imperfections is a really large deal for most engine experts. I believe honing to restore the original factory cylinder alignment is perfectly ok for about engines that accept run well for many years, and certainly ok for a low-RPM, depression-pinch tractor engine.

Special tools needed to accurately measure internal engine parts include an inside micrometer, cylinder bore gauge, and an within/outside dial caliper. Taking accurate measurements requires being able to accurately experience when the measuring tool is plumb/square to the surfaces being measured. Verify measurements and technique by checking 1 tool with another. Ane small error setting up a tool can quickly throw everything hopelessly off. Double-check everything. Never rely on a single measurement. When measuring cylinder bores, always measure out north-s, east-due west, at top, middle, and lesser of each hole. Measure several times in diverse nearby locations until it is clear exactly how and where the cylinder has worn. Nigh cylinders will accept a combination of taper, and oval with the largest dimensions beingness near the middle of the cylinder. The top and lesser will often show very trivial wear.

The taper in cylinder No.one was measured every bit 4.2100" at the lesser, to a maximum of 4.2400". All three cylinders are worn slightly oval in the eye of each bore. The specified cylinder bore range for 40-over pistons is four.2407" - 4.2432". There is just barely enough material left in cylinder No.ane to properly fit xl-over pistons, but only if the honing is done very carefully. It will exist difficult to bring cylinder No.1 dorsum to straight and round, without catastrophe-upwardly with a cylinder diameter that is too large for 40-over pistons. If this was taken to an engine shop, they would most likely say there isn't enough metallic left to properly bore and hone cylinder No.i to forty-over. I dear a claiming.

A rigid hone can be run wet or dry. Honing fluid is a lubricant, besides equally a coolant and cleaning fluid. Honing fluid may be a must with expensive automated equipment. Dry out stones cut slower, and wearable-out faster. That expense adds upwardly in a bustle for a machine store. Whatever oil residue (even finger prints) volition quickly gum-upward and prevent dry stones from cutting. Completely clean and degrease the cylinder walls. Make sure the clips for the stones and felt wipers are fully seated. Adjust the stones so they use medium pressure. If the stones churr, they are too tight. Wear a breathing mask. The inexpensive paint masks work fine for grinding dust.

These cylinders are over 4" in diameter, so the hone should be turned at about 300 RPM. Hone the top and bottom of the bores, where the diameter is smallest. Simply move up and downward enough to bring the stones fully into the bore, so the stones break-in evenly. Utilize the parts of the cylinder that show the least wear to bring the rest of the cylinder dorsum to straight and round. Stop and re-tighten the stones frequently at first. The stones will article of clothing quickly until the curve on the face matches the bore of the diameter. Cease, pull the strop out, and measure out the stones to check for any taper. Correct any taper with a sanding block if necessary. Crooked stones volition non grind a direct hole. The dark cylinder walls will go bright where the stones have started cutting. Continue to focus on the tiptop and bottom of the bore until the fresh hone marks see in the heart. Do not worry about creating a proper crosshatch nonetheless. Nosotros have a long way to become.

Pay careful attention to how the drill speeds up when stroked thru the centre, so slows at top and bottom. It may even spin unevenly where the cylinder is not round. When the drill speed no longer varies, the cylinder is straight. Hopefully, this occurs with at least a one-half-thousandth still to go earlier the cylinders are too big for the new pistons. Stop and mensurate frequently. Ever measure out in 2 directions at the top, middle, and lesser of the bore. This is hard work. It is very important to end and mensurate oftentimes. Break the work downwardly to several sessions. When you start to get tired, go do something else. Fatigue makes mistakes and kills accurateness. Never permit the hone to come up completely out of the bore while spinning. The stones should never go more than an inch out of the bore at top or lesser.

Cylinder No.ane - As described above, getting to this point was non easy. It took nearly an hr of careful grinding and measuring to remove the taper, barrel, ridge, and other issues in cylinder No.1. Work was stopped with virtually of the cylinder withal measuring 10 thousandths smaller than the minimum spec size for twoscore-over pistons. The drill has but begun to run at the same speed from height to bottom. The new pistons need to be in-mitt and individually measured to determine exactly how large each cylinder needs to be. The small night patches remaining in this cylinder are areas that were already worn nearly into the adequate range for 40-over pistons. Those areas may not completely disappear until the fine honing is beingness washed to fit the piston.

Notice the crankshaft nonetheless in the cake? Nobody hones a cake with the crank still in it! Really, it is not uncommon to do an in-frame rebuild of these tractor engines. Many of those rebuilds do require at least some cylinder honing since these engines do not have sleeves. These iii cylinder engines exercise accept enough room below the cylinders to leave the creepo in-place. The journals must be padded and wrapped to prevent harm. This solved the problem of stroking the hone too deep, and kept virtually of the grinding dust out of the oil galleries. The crankshaft was turned to work each cylinder, then the periodical and counterweights would not interfere with the strop. If the stones hitting annihilation, they will interruption, and may break your arm.

Cylinders 1 and 2 - Two cylinders. Looking skilful.

Iii cylinders direct and round. Put the used stones away as matched sets, so they will always be used together. For this outset step, the goal was to remove enough textile to correct most of the cylinder wear issues, and start sneaking up on the right oversize. I'thou very happy with the consistent measurements from top to bottom in all cylinders. It was possible that honing would non exist able to fix the wear in these cylinders. Rather than order parts that could turn out to be incorrect, I waited until the hard work was done. There is at present no doubt that these cylinders tin can be properly sized for twoscore-over pistons.

New pistons accept been ordered, but were not in stock. Unfortunately, they are 3-four weeks away. A light coat of motor oil wiped on the cylinder walls prevents rust while nosotros wait for parts to exist delivered. Remember to degrease the cylinders over again before doing more honing. The next pace will be to fit each piston to an individual cylinder.

Torque Plates - Just in example someone wants to heighten this issue, torque plates duplicate any distortion that happens when the cylinder head is properly torqued-down. I practise not believe honing with a ready of torque plates would make much difference in this extremely heavy, low pinch, depression RPM, industrial tractor engine. If torque plates are even available for this engine, I was not been able to notice any reference to them on-line.

The new "Made in USA" Clevite pistons finally arrived, and were carefully measured. Two were right at the minimum specified size for xl-over pistons. Ane was near the maxumim specified diameter. That worked out incredibly well. The job suddenly got much easier. The largest piston could be used in cylinder No.1, that had the most habiliment and to the lowest degree margin for error. Each cylinder must be honed to the correct fit for the piston that will exist installed in it. This is precision work. The specified clearance fit for these pistons is a range from 0.0027" to 0.0037". I've seen much tighter fits for some automobile engines. Still, this means we are aiming for a clearance of 0.0032" with a maximum error of plus or minus half a thousandth of an inch. There is a very good reason engine shops have automated boring and honing machines. Few people have the strength and stamina to manually run a rigid cylinder hone. A good tedious speed drill with enough torque to do the job is a very heavy animate being. This work was done in a separate session for each cylinder. Don't exist in a hurry to finish. Don't go along working when tired. Now that the strop was stroking the entire diameter, and getting shut to the right size, the stones must always be moving in and out at the correct speed to create the correct 45-caste crosshatch pattern. This crosshatch, final finish, and piston fit is where many people attempting to practise this with manual equipment will neglect. It is very hard work that must be done precisely. The piston fit and cylinder finish must exist as specified. There are no short cuts. "Almost" right is completely incorrect.

New pistons come with new wrist pins. Cheque the fit in each rod small end bushing. If they are too loose, the rod bushings must be replaced. These rod bushings looked skilful, and the pin fit was well within spec.

Lacking Tools Suck. My snap ring pliers are a recent upgrade. The ancient pair they replaced was only borderline usable. Plain the new ones take only been used for exterior snap rings. All the tips for these pliers are angled outward. They work slap-up for spreading exterior snap rings. Endeavor using them to compress an within snap ring and they sideslip out of the holes. It has been too long to find the receipt and have them back, so chuck one gear up of tips in the vice and bend them direct (the way they should have been fabricated). Now that set of tips will work for both inside and outside snap rings. The rest of the tips volition be added to my never-ending list of stuff to fix.

The next step is to cheque band finish gaps. Employ a piston to slide each ring squarely into the cylinder information technology will be installed in. Measure the gap with a feeler gauge. The specified gap is different for summit, middle, and oil rings. In this case, the rings for No.i cylinder were good correct out of the box. Ring gaps for cylinder No.2 and No.3 were a picayune tight. File the ends of each ring to provide the right minimum gap. Pinch a flat file in the gap and depict it thru to file both sides square. Mounting the file in a demote vise makes this much easier to do. I can agree the ring with two hands. Knock-off any fresh edge that would score the cylinder, put the ring back in, and measure again until the gap is sufficient. This gap provides room for the rings to expand as the engine comes up to temperature. The ring closest to the combustion chamber runs hotter, then requires more clearance. The specified clearance is minimum. Its OK to become slightly over, simply too much will reduce compression. It is best to be precise.

CLEANING:

All cylinders were finished with all pistons, and rings properly fitted for each cylinder. Each set of parts must be kept together as an assembly dedicated to each cylinder. Then comes the nigh important step. Completely disassemble the engine and thoroughly make clean the grinding and metal dust out of every nook and cranny. Go on to keep things like main caps and bearings that will be reused sorted and arranged so they go dorsum exactly where they were removed. Cleaning brushes must exist run thru every oil passage in the cake and crankshaft. Run soapy water thru the water jacket, and any places grit and dust tin hibernate. Immediately after cleaning with water, wipe every surface down with clean rags dipped in motor oil. Freshly machined metal volition immediately start to rust if not covered with oil. Unless you lot are a lot better at cleaning than I am, the oily rags volition instantly show dirt. Get over everything again with clean rags until the rags stay clean. Wrap all loose parts in rags or plastic, so they volition stay clean. The first engine I congenital was done in a befouled with a dirt flooring. Information technology took a lot of plastic bags to keep dust, dirt, bugs, and bird droppings out of that engine.

These were some cool photos.

ENGINE ASSEMBLY:

"Assembly is the reverse of Disassembly."
Yea Right, like that is ever true. In this case, the factory service manual and the I&T FO-31 Shop Transmission are very thorough, and include far more information than makes sense to try and duplicate here. Not covered in the manuals is that most assembly issues occur when parts are mixed upwardly, or forced. Check everything against photos in the manual, and photos you took. Practice non strength anything that does not feel right. Double and triple check the timing marks on every gear, before putting the front engine embrace on. Turn the crankshaft occasionally to cheque that any increased resistance feels correct for the role that was just added. If anything seems less than perfect, Finish, and figure out why.

TIPS:
i - Rubber seals should be lubricated. Utilize the same lubricant the seal will operate with. Many gaskets do not need whatever sealant. The exception to that volition be any gaskets that cantankerous a seam between two engine parts, or where two unlike gaskets meet. Use a small amount of sealant where necessary. I use a pocket-size corporeality of sealant when the gasket will not stay in place long enough to go the bolts started. Also much gasket goo volition just squish out and finish up inside the engine.
2 - The camshaft is difficult to remove and replace without damaging the bearings. Get a skillful grip and guide the lobes very slowly and carefully thru each begetting.
3 - If the Ford service manual has any directions regarding where the ring gaps should be placed when the pistons are installed, I was not able to find it. Most engine manuals say to make sure the band gaps are not aligned. Most manuals are very specific virtually where the gap in each ring should exist. With no specific direction institute, I put the top ring gaps facing front end, the second ring gap near 120 degrees abroad, and the oil ring gap another 120 degrees around. Make sure each cylinder wall has a expert coating of motor oil, outset each piston in the correct hole with the marker pointing to the front, employ a band type ring compressor, and gently tap them into the cylinders with a wooden hammer handle. Use brusk pieces of safe tubing slipped over the rod bolts to protect the crank. Turn the crank then the journal you are working on is equally far away from the cylinder as possible. With pistons in, associates lube on bearings, and rod cap screws manus-tight, roll engine upside down. Check the torque on all chief caps, then snug each rod cap down evenly. Continue checking that the crank however moves easily, then properly torque each rod cap. Cheque movement of crank again. 4 - Use a torque wrench and the correct torque for all fasteners, specially those that will exist difficult to get to later. Lubricated threads require less torque than dry out threads. The Ford service manual says the published torque values are for lubricated threads. It is ever better to torque fasteners in stages. Snug them, then torque them to something similar 30%, then 50%, then 100% of spec. When a spefific design is specified, torque each stage in the proper sequence. When not using a torque wrench, match the tool to the fastener. Don't utilise a 1/2" bulldoze billow bar to tighten a iii/8" bolt.
five - On this engine, don't forget to install the intermediate shaft for the oil pump. half-dozen - Expect closely at all stamped-steel covers earlier smearing whatsoever gasket goo on them. Straighten any office of the flanges that have been de-formed by a previous owner. Stamped steel valve cover and oil pan bolts should be snug. Cranking them too tight will simply bend the cover and ruin the gasket. Right previous damage or the gasketes will leak. I employ scrap boards to back up the flange when knocking mushroom areas around each bolt hole flat.
7 - The flywheel for a double clutch is very heavy. Don't drop it on the concrete floor (or your human foot). Install the flywheel with the engine at peak dead middle on No.1 cylinder, with the flywheel turned so the timing marks on the flange will be visible thru the hole in the engine plate. Maybe it only fits one style. I'g not certain, didn't want to have to option information technology up more than than once, and just installed it in the right position.
8 - Don't forget to install the engine back plate earlier installing the flywheel. In that location is a cork gasket that goes over the rear chief seal area earlier the engine plate goes on. Subsequently the flywheel is installed, bank check the transmission pilot begetting. Replace it if worn or missing. On this engine, install the pilot bearing retainer, then torque the flywheel bolts. I forgot to install the bearing retainer. Never seen one used on any other engine. Equally long as the pilot begetting does not fall out before the transmission is installed, no worries.
9 - Reattaching an engine to a transmission is always harder than removing it. Getting splined manual shafts lined-up and the engine slid into identify is always more difficult going on than coming off. This tractor has 2 sets of splines that demand to be lined up. One play tricks that helps is to pre-align the splined transmission shafts with each clutch disc. Some of my photos show the load leveller and long bolts that were used as pins to become the engine properly aligned. This engine is then heavy, I decided to wait and install the cylinder head equally a separate pace.
10 - Once the flywheel is in place, brand certain engine is nevertheless at summit dead eye (TDC) on No.1 cylinder. Turn engine slightly so timing marks are at 2 degrees earlier TDC. Install the distributor with the vacuum advance tin can pointing out to the side, and set it and so the points are only about to open with the rotor pointing to the No.1 spark plug post. Set the distributor adjuster clamp so the hold downwards bolt will be mid-way in the timing adjustement slot. If this is done right, the adjustment slot will barely be visible adjacent to the vacuum advance. Done incorrect, the vacuum advance will be too far dorsum, and will not permit the carb to exist bolted in place. I had to remove, reinstall, and re-time my distributor when the carb would not fit. Install distributor cap.
11 - Most head gaskets exercise not need to be retorqued. Maybe. I still recommend checking caput bolt torque after the engine has been thru a heat wheel, or two. On this engine it is a pain to remove the valve cover, but checking head bolt torque is withal much easier than having to replace a head gasket. I always bank check, and have never had a head gasket fail.
12 - Don't forget to put the front fuel line in place when installing the intake manifold.
thirteen - Use new brass nuts for the exhaust manifold. Replace whatsoever rotten studs with new Grade viii studs. I had to make a special one to replace the extra long one.
14 - Brand certain you are done adjusting valves and have bolted the valve embrace in place before bolting the air filter associates to the firewall.
15 - If the lower radiator hose hits the front of the engine, the hose is upside down.

It has been an interesting month. Rain, pelting, and more than rain. The creek flooded three times, somewhen floated our little bridge off the foundations, and started taking it downstream. It took a couple weekends to salvage materials before the side by side flood demolished information technology. Now at that place'south a stack of lumber down by the creek waiting for dry weather and a meliorate bridge design. We merely accept near an acre on the other side of the creek, but it was nice having good access to it.

Sidetracked once again: Unwrapped the new steering cycle. It appeared to be decent quality. Then I saw the el-cheapo plastic center cap. That just will non do. The one on the tractor appears to exist a hard plastic, but it was finished a lot meliorate. I could accept just polished or possibly painted the old ane. That would have taken a lot less time than it took to carve and shine this billet aluminum one. I take a small shop lathe, and a buffer. Might equally well become some employ out of them.

The steering wheel should have gone on easy, but the hub does not appear to be tapered to lucifer the steering shaft. It would not go on far enough to go more 1 bolt thread started. This is merely another common example of new replacement parts that don't fit right. A grinder and round file were used to create a taper in the new steering bike hub, then the steering wheel would fit properly.

This matches the shift lever knobs.

ENGINE ON TRACTOR:

Ii 5/eight" bolts vi" long, stuck thru the lower engine/transmission mount holes were a big help aligning the engine with the manual. Adjust the height/angle to get the guide bolts into the holes in the manual. Adjust height and angle until the guide bolts are not binding. Then start sliding the engine into place. Pre-aligning the splined shafts with each disk certainly helped make this ane of the easiest engine installs I've ever washed.

The acme deck of the engine cake was covered with record to go along clay/bugs out. A rag was thrown over that for additional protection.

Front end AXLE Associates REINSTALLED:

No surprise, the front end beam support associates is very heavy, and awkward. The surprise was getting it jacked and bolted into place without smashing any fingers. Bolt outer axles and radius rods back on, and information technology will exist setting on 4 wheels once more. These radius rods have a slight "hump". They could be straightened, but I'thousand just going to flip them, and allow the tractor outset bending them dorsum.

INSTALL CYLINDER HEAD AND Accommodate VALVES:

It might have been possible to gear up the cylinder head on by hand. The engine hoist was right in that location, and made it so much easier. Valves should be adjusted cold as described in the manual. The valves on this engine are difficult to adjust. It is hard to notice the right spot to measure clearance between rocker arm and valve stem. Terminal fourth dimension I adusted them, masking record on my feeler gauges helped brand certain they were going to the same spot each time.
The distributor was checked once again to make sure the points were properly gapped, and initial timing set to open points at ii degrees before top dead eye (TDC). No reason this setting can't be pretty darn close to perfect before the engine is fifty-fifty cranked. I've done this a few times. Also much advance is worse than also piddling. Make sure any small mistake is slightly less advance than specified.
Carb setup is similar. If the carb has been rebuilt, apply basic demote settings close to where the screws were when the carb was pulled. If this is a new carb, or previous settings are unknown, slightly rich is always better than too lean. A fast idle setting is meliorate than tedious. We are not going to endeavour to get this engine to idle until after it has been run hard a few times.

CLEAN AND Paint:

Another reason reassembly often takes longer is when parts are so muddied nosotros stop upward cleaning and painting as we go. There really is no better fourth dimension to clean and pigment, than when the tractor is in pieces. In this case, a mistake required repainting several parts. Simply put, Navy Blueish paint is non the same as Purple Blueish, DUH. This is what I become for painting in the evening with poor lighting. All the parts that were cleaned and painted after piece of work during the week turned out to exist well-nigh black when they were brought out in the sun. The only right color on-mitt was in a quart can, so this turned out to be a major painting twenty-four hour period. At least the conditions was almost perfect for it.

There was quite a bit of paint left in the spray gun, so rather than poor information technology back in teh can, a quick scrape and pigment of the entire frame was washed. The previously-painted sheet metal panels were just going to exist cleaned. Information technology may have been a mistake, but I couldn't resist shooting clearcoat on them. Clearcoat may exist too shiny for a working tractor. It does provide more than UV protection for the decals.

PCV SYSTEM:

This is a practice-over of the PCV System that was installed several months ago. This engine originally had a road draft tube system. A long tube ran from the valve encompass neck down adjacent to the radiator to vent fumes from the manifold. Modernistic closed crankcase ventilation systems are much better. The road tubes basically burp fuel/oil fumes all the time, and provide a place for bugs/clay to get into the engine. Engines with airtight PCV systems run amend and the oil stays cleaner.

For this redo an elbow plumbing equipment and standard PCV valve were connected to the original draft tube connection at the front of the valve cover. This connection already has a baffle to aid go on oil inside the valve cover. The elbow fitting allows a standard PCV fitting to be installed in the vertical, avoids running into the radiator hose, and boosted insurance that only crankcase fumes will get sucked into the intake manifold. A 3/8" suction hose was used between the new PCV valve and a new "T" fitting installed in the vacuum port on the intake manifold. The original restricted distributor vacuum advance fitting was reinstalled on the exterior end of the new "T" fitting.

Do not attempt to use the distributor vacuum fitting for PCV. The distributor vacuum fitting has a small restricted hole to provide a metered vacuum source. That distributor fitting will not flow plenty for a PCV arrangement. For some reason the previous owner had removed the distributor vacuum advance and plugged the fitting on the intake manifold. Vacuum advance improves efficiency and driveability. I have no idea why anyone would choose to run without it.

Now that nosotros will exist pulling fuel/oil fumes out of the valve encompass with a vacuum line, a new fresh air vent is required. The ideal location would be at the opposite stop of the valve cover. Unfortunately that stop of the valve cover is directly under the air filter housing. 1 choice was to come upward with a nipple betwixt the valve cover and air filter housing. Aligning two holes for that to work out well did not await easy, and the new valve cover hole should not be in a location that is probable to be constantly drowned in oil. Straight over a rocker arm would exist a bad choice. I marked a spot in front of the air filter, over one of the rocket shaft mounting/head bolts. Took the valve embrace off and drilled the pigsty so metallic shavings wouldn't end up inside the engine (duh). Many types of universal valve cover fittings are bachelor to attach a PCV vent, filter, or hose to this new hole in the valve embrace. Some engines used a split up PCV breather/filter. Most mod engines accept a PCV vent hose going to the air filter housing. On this one the little filter sabbatical plumbing equipment seemed like the best selection.

Any good conversion should look like it could have been original equipment. This may still have too many clamps to be "original". For at present, this should work, and cypher is in the way of anything else. UPDATE: After running the engine a few times, this PVC organisation works fine. It may accept leaned-out the fuel mixture some, just not more than than 1/4 turn on any mixture screw.

Starting time Crank:

Everything is ready to go, wiring, fluids, linkage, fuel line fittings, hose clamps, and various fasteners have been checked at least twice. Some fresh rebuilds have been ruined past starting them with no oil in the crankcase. Don't exist that guy. Battery is fully charged. Spark plugs take not been installed. That's right, spark plugs are out. This engine was damaged by running it without oil force per unit area. Before firing it up, cranking with no compression is the terminal no-load test to heed for annihilation that does non sound correct. If the piece of work was done right, there shouldn't be whatever issues. It should only have a few seconds cranking without spark plugs to come across solid oil pressure on the gauge. If there is a problem getting oil pressure, cranking with no compression isn't going to injure the engine. In this case it took a little longer than expected to see oil force per unit area. But long enough to brand me start to feel ill, and so the gauge jumped. Next, check plug gap settings, install spark plugs, and check firing order (1,ii,3 Forepart to Back).

After any major engine work, care for the engine like a fresh rebuild. Information technology may non seem logical, just the merely way to run a fresh rebuild is difficult. The worst thing we can exercise is "babe" a rebuilt engine. Do non permit information technology idle. When it fires, immediately rev the engine to around 1500 RPM, and hold information technology there for near 5 seconds. Information technology will make some smoke. There is oil in the cylinders. Permit the RPMs drop a fleck, so rev it up to around 1500 once again. Hold information technology there for near ten seconds. With the proper finish on the cylinder walls, rings should seat immediately. However, making good cylinder pressure will greatly assistance the rings to seal and burglary properly. The smoke should clear up quickly. Watch for smoke, sparks, and leaks. If possible, put the tractor in gear, and go for a short, difficult ride. Accelerate, put a skilful load on the engine. Run information technology long plenty to get shut to operating temperature, but if in that location is any strange noise, smoke, or major leak, close it downward, and fix the problem.

OK, This did non go as smoothly as that write-up implies:
PROBLEM 1 - As it says in the manual, the proper procedure for starting this engine is to CLOSE THE THROTTLE, then turn the key. The engine did non commencement, because my aftermarket foot throttle was property the throttle partly open. It took a few whacks to come upward with a throttle return spring with the right length, tension, and a practiced mode to attach it. I fiddled with that after work for a couple days. Amazing how hard something so simple can exist.
Problem 2 - One fuel fitting was dripping, another 1/four plough took care of that.
PROBLEM 3 - With a throttle return spring in place, the engine started right upward. It idled smoothly, but when I tried to advance the throttle, the engine instantly died. Close the throttle and endeavour again. It started right up once again. This fourth dimension the throttle was opened v-e-r-y southward-50-o-w-50-y until it was effectually three/4 throttle. Put it in gear. Go for a ride. The timing is obviously off. This engine did non have the vacuum advance hooked upward when I got it. Now that the vacuum advance is working, what it seems to be doing is trying to stall whenever manifold vacuum drops. Basically, every time the throttle is increased, or load is added, the engine tries to quit. That probably means there is not enough initial advance. Loosen distributor bolt, plough distributor a small amount clockwise. The distributor turns at 1/ii engine RPM, so moving the distributor 2 degrees equals iv degrees at the flywheel. Huge difference! At present the engine revs similar it should. I might use a timing light to check where it is subsequently running the engine and tweaking information technology a few more times.
PROBLEM 4 - For the entire kickoff drive, there were flaming embers from the muffler dancing on my freshly clear-coated hood panels. Proficient affair information technology rained recently, or it might accept started a forest fire. At least the engine was running and got up to operating temperature. Close it down, become some water, spray the hood panels, and see how bad the pigment is. Some of the flaming $.25 of rust got stuck in the new clearcoat. Those were easy enough to flick loose. Once the muffler was cool enough to remove, there are several new holes in the outer jacket and a lot of loose rust within. This muffler is shot. Rummaged around the barn and found a resonator muffler with a stainless steel tip, and fabricobbled a flapper and hinge from some scrap stainless steel.
Problem 5 - Taillights work, just headlights don't.
Trouble 6 - Dash idiot lights work, simply fuel and temp gauges don't.

This photograph was just earlier the kickoff run.

This the temporary muffler and flapper that was used until the right parts were delivered.

This chapter came to a happy ending. The engine repair took 4 months to complete, working by and large in-between normal chores and other projects on Saturdays and Sundays. Reassembly included a lot more than than just putting the engine back together. The plan was for this tractor to have over most of the work, then sell one or all of the older tractors. Most of the problems listed to a higher place were not hard to gear up. The headlight problem ended up beingness a rotten female person butt connector in the wire harness. Temp gauge was another wire harness issue. Fuel gauge started working so quit again and may need a new sending unit.

Too MUCH TRACTOR FOR U.s.a.

This is a bummer. With the engine running good I was really looking forward to tweaking the distributor timing and Holley carb. The Holley gets a lot of bad publicity on the forums, but there is nothing wrong with this 1 that won't go away with a picayune tuning. Unfortunately, it very quickly became obvious that this is way more than tractor than is practical for our mostly wooded property. Romping and stomping a fresh 50hp tractor in the woods has already gotten me in some trouble. My smaller Northward-Tractors can easily go into places the 3000 just does not feel condom. The square hood is harder to see around and nearly 50hp is overkill for any of the work we need it to do. I was really looking frontward to this tractor becoming my go-to motorcar for everything. Now it looks like I'm going to take to sell it before we end up climbing a tree or something worse.

I LAST TIP:

No matter who did the engine work, modify the motor oil at the very commencement indication of color (dirt). There are a lot of nooks and crannies in an engine. No matter how well it was cleaned, there is ever a take chances some grinding dirt might remain in there somewhere.

I'm happy, establish a buyer and at least did a footling better than break-even on my purchase price and parts pecker. Sad to see it go downwardly the driveway though. It's a really-overnice tractor that I may exist trying to buy back one 24-hour interval.
