WD 45 Engine Rebuild

Hello All,

I think I've finally faced the fact that I need to rebuild the engine in my WD45. It won't run at all now, but when it did there was oil pouring out the #3 exhaust manifold connection, plus it was running very erratically and wouldn't run unless the choke was pulled all the way out. It's been sitting neglected all winter but my intentions are to rebuild the engine this summer as a project.

I bought the Allis Chalmers Rebuild and TuneUp videos offered on this site and they are excellent, and I have rebuilt diesel engines in the past as part of my previous job.

I figure I should replace the liners, pistons, rings, all bearings and gaskets and have the valves checked. We have the IT manual and the Allis Chalmers owners manual.

A few questions have come up as my wife and I prepare for this undertaking (she's very excited about the project because her late father farmed a lot and was always doing stuff with his engines and tractors), mostly about the equipment we'll need, such as engine lifter (cherry picker) and engine stand, tools, etc.

You are the folks with the experience so I came here first. I'm looking forward to the project and I know we can do it, and it seems it would be better to invest the time and $$ into the tractor we have, rather than go out and buy another tractor that may have the same issues. Besides, we've grown attached to the WD 45.

I'm all ears for advice, thoughts, prayers, do's and don'ts, etc.

We'll probably start the project in a month or so.

Thanks.

vic

if you split tractor be real carefull with supports...they dont balance too good and yer apt to lose whatever they fall on...A-Frames and chain hoists are safest.
good luck

You'll need a decient 1000 lb engine stand ($80 or so at a farm store), any kind of engine hoist ($200 should get a good one), an engine leveler is nice to have, check Northern Tool or your favorite auto parts store should be able to order one. Couple of tricks I've learned doing mine. Use a 6" extension to remove the rad bolts. Stick it through the hole on the bottom of the frame rail, THEN put the socket on. Pain in the butt any other way. Take the steering shaft apart at the u-joint in the frame and pull the steering wheel end out, makes engine removal easier. A good oak 4x4 and maul should pop the liners out. Use regular old veg oil on the o-rings to reinstall. Do NOT trim the pan end gaskets. You'll think they are too long, but they are not. Kit should come with some little spring clips that hold it in place till you get the pan bolted on. If I were you, I'd do the cam bushings. The cam actually supplies oil to the main bearings so worn busings drop oil pressure and reduce the lubrication of the main and rods. I can't think of anything else at the moment. Might not hurt to have an I&T or AC service manual, the torque specs and info help a lot. I assume the video's discussed the offset attaching of the rods to the pistons. Just follow the directions with the kit and you should be fine. If you have any other questions, I'd be glad to help out. My e-mail works and I've done a couple of these.

By check the valves, I hope you mean check for worn valve guides, then grind the valves and seats. Be sure you get the piston pins adjusted correctly, I don't want to read about any pin grooves in the sleeves later on.

Before you buy at parts be sure to have a good machine shop check out the block, crankshaft etc. That way you don't buy standard rod and main bearing and end up with a crankshaft that has been tunred say 20 under etc. Also be sure to get an I-T manual if you don't have one yet. The engine in a WD or WD-45 isn't all the hard to pull out. BTDT a few times. Shoot I just built a WD tractor from a pair of dead tractors
