For You Allis Experts

I"m an early IHC guy and know next to nothing about an Allis Chalmers other than I"ve always liked the looks of them. I acquired this old girl from my brother-in-law and I assume it"s a WD. I remember the WC having a round differential. I cannot find a serial number for the life of me to verify. She"s complete but the engine is stuck. Any of you experts tell me what I"ve got? I noticed she has hydraulics and a two point(?). I guess I'm trying to figure out if she's worth restoring, selling or parting out. Pictures follow.

by all means save it, paint it and use it.
great old tractors.

mix up a 50/50% solution of Acetone and automatic transmission fluid.
pour this solution into each cylinder and put the plugs back in,
wait a week or two and see what happens.

this solution is suspose to be the #1 penetrating fluid.
as you well know, dragging the old tractor around poping the clutch can only break some drive train parts.

good luck with the old tractor.
 
Well, first off I am not an Allis expert. But from what I see the curved gearshift lever tells me it is a WD45, and it has a delco distributer, not a mag.

Just my 1 1/2 cents.

Your mileage may vary.
 
Thats a WD45 you can tell by the shifter is bent a wd is straight these tracoters don"t have individual serial numbers, there should be a serial number, casting number on the engine that tells that its a wd45 or it could be something to do with the block if i could remember correctly theres only very suttle differences
 
That's a early WD. IT has a cast iron clutch pedal and steering shaft support under the gas tank. The serial number is located on the left rear of the differential housing or under the left side brake cover.
 
Yes, it's a WD-45. The tractor serial# is located on the rear axil, just to the rear of the left break access plate, ( I just asked this same question a few weeks ago).
50/50 Acetone- ATF, but you need to make sure there is no water inside of the engine..put the plugs back in and cover the exaust, let it sit for a week, then remove the plugs and rock the tractor back and forth in high gear by pushing and pulling "by hand" on the rear tire. I have a WD...nearly the same thing only less hp and alittle older, good old tractors.
 
WD
The engine has the magneto drive (WD only) but the mag. has been replaced with the aftermarket Delco Remy dist. drive assy.
It looks like the short cyl. head, but I can't tell for sure. It has a WD air cleaner. It has a replacement (WD45) manifold.
No snap coupler.
So, unless someone has pieced together a real mongrel, it's a WD.
 
I vote WD. Curved shifter looks like it was done with a torch. Distributor conversion, plate on the side of the block, pin hitch. Serial number will be just above the bolt to the left of the differential cover. Should start with WDXXX Looks to be in fair shape. The spin out rims are expensive to replace new, but can be patched. They came factory with fluid in the rears, and have a tendency to rust around the valve stems. If you can get her broke free, it's a fun tractor to run.

I agree with Black. Shifter is wrong for any model. Probably a WD. If it has a rectangle plate bolted to the right side of the block behind the oil filter/ magneto area then it's a WD engine.
 
Check out the skinny rims and small tires - not 45s; the hitch is WD ;the head is WD; the low fenders, the mag drive; but most of all the PTO drive is the dead giveaway - all WD. Someone did bend up a straight gear shift (they also put the battery in sideways) but those factors just say WD with bent up (not curved) shifter & sideways batt!
 
Not only is it a WD but it is an early one. Give
away for that is the steering shaft bracket just
behind and below the oil filter being made of cast
iron.
 
Had to look that one up. That style was used on tractors prior to sn 10595. I have one on my WD, also have the newer pressed steel cup. I have one of the early style plates for sale on eBay right now. Item # 190809258697

No doubt it is a WD, not a WD45. SN is on the left rear vertical face of the differential....will start with WDxxxx. 146606 or under. It has a distributor, not a magneto. SN 136318 was the first WD with a distributor....if your SN is lower, ignition was switched. Comments about curved shifter are totally wrong- that is not the AC curved shifter....just a cobbled up thing. WD had the pin hitch, like this one has. Can be changed to a Snap-Coupler bell housing.
 
Serial number could be in two places. Very early tractor will have number inside of green circle. Later ones as JMS said will be in red circled area. It is not uncommon to find an early featured tractor with no serial number as there were troubles in the rearends that required replacement of the entire housing and a lot of mechanics neglected to restamp them.

Clutch pedal looks like it is from a WC. It is extended WAY back, for a very short person? Maybe a youngster?
The Battery box is in normal, it is just the battery that is in sideways.
Shifter looks like it could have been taken from a WC also and bent up and put into this tractor.

The hitch setup (WD) and a lot of other things make me believe that this is indeed a WD tractor, but with a WD45 engine in it.

Is there a plate on the right side of the engine? It runs the length of the block behind the distributor/oil filter area. It sticks out like a sore thumb. The serial number for the engine is behind and slightly to the rear of the carb. What does that number say?
From what I can see, there appears to be NO plate on the right side of the engine, it looks like a 45 engine.
 
The distributor is a magneto replacement kit from Delco-Remy.
The bolted belt pulley hole cover was only used on very early WD's.
The manifold is a replacement styled like a WD-45.
The shift lever is just mangled for whatever reason.
WD...1948 or 1949 would be my guess.
 
I think it is really neat that you posted this pic with the circled areas. Proves the old adage about a pic being worth a thousand words! That issue comes up here so often. I remember how your green circled area is in the early Op manual.....SN 4004.
 
Gotta admit Nathan. This is the first time I've seen a WD vs WD45 question go 2 pages. Those in the know have all chimed in with WD. Would like to see the OP come back with the serial number..

Sure why not, lets make the model official . If the season was spring to fall most of us would be out doing something , so this kinda fun gets me over the winter blues !!
 
JMS, I was looking at a WD45 manual for another thread about fluids and that same number 4004 was in it. I think they used some stock pictures for the later books. WD45 book shows both areas circled.

Maybe later next week I'll get a chance and check for those numbers. Thanks a bunch guys, thread is full of good information. For the curious minded, I did find several casting dates in the October 1948 range if that helps?
 
It's absolutely a very early WD and not at all a WD45. To me it sure is worth restoring but I never sell my restored tractors as they always cost more to restore than what they are worth. It is an early WD which I have only seen a few of. The clutch pedal and steering support bracket are fairly rare to see as is the serial number that should be up next to or under the left brake cover. My brother has one. Yours has been farmer modified with the messed up shifter, added bracket on the rear of seat, broken light on fender where the bullet style tail light should be. Many WDs have a welded up drawbar bail but that one looks great. Good luck.
 
Thanks for all your help guys. Was able to find the serial number up top and it's WD3128. How early is that number? I have enough IHC projects and may end up selling this one. Any particular value for a WD like this one? Thanks again!!
 
My book indicates first year of production- 1948. I have no idea on value, but I would say it's certainly a keeper. It's in pretty good shape compared to many I've seen.
