 Topic: 1951 WD
Posted: 07 Apr 2019 at 11:48am |
The seller just dropped this off today. Not exactly pretty, but it runs pretty well and everything functions minus the PTO that's missing the shear bolt. "Supposedly" the engine was rebuilt later on in its life.
It's going to need a number of leaks fixed (including what looks to be the rear main seal) and hoses, a belt, etc. The drawbar bail has been welded on but looks fairly solid. Rims look good. It'll need a front tire soon, and it sounds like there might be some bearing noise or something back around the axles or final drives.
Otherwise I'm hoping I can get out and disk with it soon and get some grass seeded with my JD drill.

Being mechanically sound usually trumps being pretty, and it sounds like it won't take much, and it'll be mechanically sound. Good snag! Darrel

Looks like a pretty good find!
What's with the welding of the drawbar area?

It wouldn't hurt a bit, to drop the final pans and clean out any sludge in there. Ya never know, it might have the original lube in it.
Then while the pan is off, you can eyeball the final drive gears, and maybe pry around a bit to check for loose bearings. Straight gear WD's always did have more gear noise than the later model with constant mesh trannies.
There is no "shear pin" in the PTO. Anything run off it, needs a slip clutch or a shear pin of it's own.
The bolt that connects the PTO output shaft to the long shaft, is a case hardened shoulder bolt.

As far as I know the flip up seat was an after market item.

I'm not sure. Someone must have broken that side of the bail at some point. It's not very clean looking but it seems to be solid, so I'll leave it for now.

Good point... It probably isn't designed as a shear bolt, but sometimes you get lucky and they do shear. I wouldn't be counting on it.
I do plan to drop the final drive pans. This tractor is definitely noisier than the WD I grew up on, which was also a straight gearshift tractor.

Dad's '52 WD didn't have it either, so I guess I don't know what I'm missing!

I've got two operating WDs here and one has a much noisier drive train than the other, but it's been that way for the last 20 years and hasn't gotten any worse!

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!

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.

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

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

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.

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

I saw the plate. I saw the Power Crater sticker on the side. Those stickers must have been a dime a dozen once upon a time.

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.

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.

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 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.

Your 1951 WD numbers fit in nicely on the WC, WF, and WD block chart I've been putting together. Block casting number: U 3019-31 Engine serial number: WD309752PA Tractor Number: WD101353

I dont know why I gravitate to these old rusty hulks too?:) I just know they have pretty good bones and they did a ton of work for their size in their day! Love to hear the governors open up, and they sound good! I need to get to the shop!:) We need more pictures and updates! Regards, Chris

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 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.

Looks good! About how mine looked when I got mine from my grandfather. It is almost completely restored now and hopefully will be firing it up within the next week. The first time it has been started in almost 2 years!
Looks like it has been converted to a 12v alternator and a distributor?

When my dad gave me the WD, e said that a "WD-45 kit" was installed in it sometime in the 60s. Is that a thing / what's going on here with the engine ?

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. ;-)

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
