is this a WD or WD45 ?

Hi Guy's, New to your forum and need your help already! Just bought my first Allis. I bought it as a 1949 wd.  I was pretty positive it wasn't a 49 ( I could see 50 and 51 dates), but to further confuse the situation, I went to pick up a loader for it today and the fellow had 6-7 wd's and wd-45's and 60 years of knowledge about them. While looking around at his piles of treasure's I started to wonder about the exact model I had purchased. The serial # on the rear end is WD47054 but the engine doesn't have the large plate on the side of the block like his WD's . Mine also has a distributor whereas his WD's were all mag's. His WD-45's looked like the exact engine, had a distributor.  How can I tell what I have? The only part I got for it so far was a starter drive which should be interchangeable...

the curved shifter is not 100% proof.

Don, what gives it away as a LeRoi engine? There is a pair of them in some Bantom draglines at my local salvage yard. They look like AC's to me.

Don't mean to sound like the correct police, but that loader frame is mounted about a foot too far forward.  No big deal unless you are lifting real heavy stuff or have short arms as you'll have a hard time reaching the trip lever.  Also, if thats the stock oil pressure gauge location, it's darn near worthless.  Would that engine have originally been on a power unit?

The Leroi engines have that canister oil filter, and alot of them don't have a thermostat, or even the location for a thermostat. The water manifold is just a straight shot up to the radiator hose.

WD47054 is a 1949 WD, the straight shifter is always a WD. It also has had an engine swap and combine wheels put on it.

1. AC never used the engine in their tractors. As mentioned before, this tractor has had an engine swap.
2. The rain flap won't catch on low hanging tree branches this way. And if you drive into a rain real fast it won't flood the engine through the exhaust

I went this last weekend and picked up a loaderforr it. It took less than 2 minutes to figure out the frame was way to far forward! The mount that's on it has been butchered in the front mounting plate area. The loader came as a complete assm. but I didn't put the new mount on yet. Didn't know which holes in the frame were the correct ones. Oh ya and the way it's cobbled on it would have taken all day just to knock the welds off!

Do you know serial # location for A-C and leroy engines? There is about 3/16" of paint on everything and a bugger to find any numbers.. Still waiting to buy a manual until I find out what it is.

Allis sold cast blocks to LeRoi. LeRoi then added other components such as head, covers, oil filter etc. At least that's the way I understand it. I have also seen the 6 cylinder version of this engine in an air compressor with two of the cylinders used as the pump for the compressor.

Your favorite multi weight engine oil; a universal transdraulic or Hytran fluid for the hydraulics and tranny, differential; and 80-90 gear lube in the final drives is what I have used for 30+ years in my WD45. 

Gov uses engine oil.That's the oil fill cap in front of distributor.

14.9-28 would be what most had. The tractor came with 4 rail power shift wheels. The rims and wheels on it now are most likely 26 inch combine wheels and don't allow for adjustments.
