When 45 came out,it had 1/2in more stroke than WD.Same bore.Took matching pistons with the wrist pin moved 1/4in. Rods would interchange but WDs were shim adjust and 45s were precision.

wjohn, Your getting right into it! Awesome! Yes these air cleaners can have a bunch of gunk in them! Carb doesn't look to bad! Regards, Chris

The air cleaner didn't look so bad at first. I tried blowing compressed air through the top and wasn't getting much flow through it, and then I saw the mud dauber nest. There's a pile of other gunk up around that area where the intake tube of the air cleaner transitions into the space between the outer wall and the inner wall that holds the mesh. Not sure if that makes sense but on these air cleaners the air comes down between the walls and is then sucked up the middle through the mesh to the carb. Anyway, it's pretty tough to get to and it's nice and oily, so I finally figured out that I could shove a scrap piece of metal shipping banding in and work the crud loose.
I never have found a good tool for screwing/unscrewing the needle valve seats in carbs. This old reciprocating saw blade works okay but could be a little stiffer.

Good thought. I bet it's for a missing surge spring. I seem to recall Dad's WD had a spring hooked down to the engine block coolant drain petcock, and there's nothing of the sort on my tractor.

Well, it's been sitting since it was dropped off and I finally have space in the shop. It fired right up.
I drained the engine oil, coolant, and gas. The gas tank has some sediment in it but I think it'll clean up okay. The air cleaner cup had purely water in it. I took the carb apart since it was leaking a little gas and it actually looked pretty good inside. The float seems to be okay but I could see some junk up in the needle seat, so hopefully that's all the problem was.
The oil leak at the rear of the engine was mostly coming down the inspection cover. Took that off and the flywheel appears to be a little oily. I had not too high hopes that only the pan gasket was leaking but I'm pretty sure that the rear main seal is the main issue. It was leaking slowly when not running, and leaked a drop every 20 seconds or so when running. I'm not sure if I'll pull the engine to do the rear main seal now or wait until winter. There's a leak up toward the front of the engine somewhere too but not nearly as bad.
Anyone know what this mystery wire could've been for (second photo)? It's just hanging off the governor shaft tube but looks like it was tied to something once upon a time.

The only thing I would point out is that the tall head started sometime in '51 (engine serial number 289000) so there are plenty of WDs out there that had it from the factory.
I just picked up a WD field cultivator from a forum member last weekend as well. I'm hoping it'll be perfect for knocking out some spring weeds while ignoring a few rocks in my fields.

Yep, it's before the changeover to the distributor, so it would've originally had a magneto. I'm annoyed that someone hacked off that corner of the grille for the distributor but I see that all the time.

WD45 had the same diameter 4 inch piston as the WD. The difference was in the stroke of the crankshaft and the compression ratio with a shorter piston for the longer stroke.
Oversized pistons don't make a "45 kit" . You would have to change the crankshaft and the pistons. You could also put a 45 crank in with WD pistons, and have a BIG jump in compression, that might make it hard turning over.

Trying not to highjaclk the thread: bhaynes has some of this correct. But you never really know about these old engines till you open them up. Very few are as they were from the factory. When my Dad and uncle put a 45 kit in the old WD's. it was moving from 4.00 dia inch stock pistons to oversize 4.125 dia pistons and sleeves. Most times the stroke remained as factory with a 4.00 stroke (factory for a WD) Now the WD45 had the same piston bore options but had 4.50 inch longer stroke. Different crank. It also had dished power crater piston compared tot he WD flat tops. So most of these parts are interchangeable and these engines have been confiqured many ways since they rolled out of the factory doors. A WD block (plate on the side) can be used to make a WD45 engine. And a WD45 block with no plate, was the replacement block at some point for all these. So it can be a mix and match of components to meet the owners needs. I think I have most of this right but feel free to add. Yes the head is taller on a typical factory WD45 also.
Back to the current channel Wjohn has confirmed this nice tractor is a WD with some WD45 decals. I would drive it!:) Regards, Chris

I don't want to misquote anything - but to my understanding, the WD-45 engine has bigger pistons. (by like .5in in radius I believe) and the biggest noticeable difference is the WD-45 engine doesn't have a removable push rod cover. It's a solid block. It seems to be common for a "WD" model to have a "WD-45" engine in it.
Could be TOTALLY wrong and I am very new to this, but that was what I thought and heard at one point. ;-)

I had time to read through the first two pages of your WD-45 thread over lunch and have been too busy running around to finish the rest of it, but I'll keep reading when I get a few minutes. It looks like it should be a fun read. I agree they're the good ones to start with.
I have a decent list of what this WD needs before I feel comfortable calling it totally field ready (radiator hoses, all fluids, carb kit, etc.). I need to put an order in and pick up the other stuff at TSC here soon, and get that front tire replaced. The weeds in my fields aren't getting any shorter.

Nicely done - I didn't know anyone was tracking the engine numbers as well. I just about couldn't find the 1 in the -31 on my casting but it's there.

I pulled a spark plug and measured the stroke at 4"... Just a plain old WD crank. The carb is a TSX 422 so at least that matches up correctly.

I think the seller said he had to replace the governor at some point, which would explain why it's the newer housing and fill cap. Good catch.

I thought I remembered seeing something about the tall head being on some of the WDs - Dad's '52 also has the tall head. Looking in the parts book shows that engine SN 289000 on up had it which would mean it's probably original to this tractor, too.

Dad's '52 has those same Power Crater stickers on it, too. I almost wonder if AC put them in with a "45" engine kit or if AC only offered WD-45 decal sets for service parts, and people wanted to use every last decal.
I didn't include the engine SN for fear of picture overload in my thread, but here it is. Seems like it could be original and I was glad to see the PA suffix, although if the internals have all been swapped out that may be moot. I should stick something down the spark plug hole and see if I can measure what the stroke is.

Yep Lonn is right thats a WD block for sure! I completely missed that side plate. But as mentioned it may be a 45 engine lurking inside that block!:) Regards, Chris

Sideplate on engine means a WD or WC engine. Of course I bought a WD once but knew right away it had a WD45 crank in it by the way it snapped to attention.

I was surprised to see the WD-45 power crater decals and the 45 head. Looked at the shift lever and thought it may be a very late WD - they had the constant mesh transmission. Over all looks good for a tractor "pushing 70".
Can't believe they are still operating. They made them good At Allis Chalmers. Good Luck! Bill Long

wjohn, Man does that look like the ones I have brought home! It has indications that the engine may be a WD45. Looks like the oild filler cap is a WD45 type. Not sure but the head looks like the tall one. Has a WD45 decal on the rad shell. Power crater decal on the block??
Yea most have the welded bail. I have had to replace all three of my bails, I have one that's welded but looks pretty clean as a spare. Your tractor looks like it should function well for some discing work. Rims can be a big issue, so thats a plus if yours are good. Looks to have been mostly converted to 12 volt (alt) but still has the ballast resistor. My 45 had that too. Still cant figure why folks dont get the right coils when doing the conversions?? And yes some rear ends are very noisy. My wide front WD is very loud! I see you have a WD45 also, so you know the ins and outs of these already! Looks like a good tractor to add to the herd! Congratulations! Regards, Chris

Dad's WD-45 had noise somewhere in the rear. Never knew what it was. Had it in the 1960's and still does. Never seemed to get any worse through the years. Maybe if it does get worse we'll figure out what causes it.

i have three running WD's and they all are noisey in the gears, but yet all different tones of growl. I guess it depends on how hard they were used in there life with gear wear or run low on oil and got hot like my 49 WD it has a distinct howl in 2nd and 3rd, bearings were replaced when it happened but great grampa couldn't afford new gears. I don't even need to turn around to see what tractor is coming its not loud just a distinct sound!
