WD or WD45?

hey there.

I had purchased a WD45 to pull antique tractor pulls.
I went to practice, and it had a little problem, so I didn't pull.
While there, a few other allis guys were looking my tractor over.

they said I have a WD engine.

Well, it appears that I might have the WD45 engine, but just the WD head on it.

My serial number says WD45.
Curved shifter says, most likely WD45.

The guys told me that since I didn't have the long plate on the Right side of the engine, that this engine was a 201, therefore a WD engine. The head, definitely is not the tall one.

then, i've been doing alot of reading, and I've read that the WD has the plate on the engine, not the WD45. So I looked at my junked WD and my junked (headless) WD45.
Our old WD has that plate. Our WD45 does not have that plate.

My WD45 that I plan to pull with, does not have that long plate, it just has the shorter head on it.

Does this sound right? It appears that I have a WD45 block, but a WD head on it?

Below where the oil filter is, there is a small spot that has a 2"-3" plate, with 2 bolts holding it on. Its like a little red

cover, where the 2 junked tractors just have a formed area in the block, but no holes or bolt holes. Any ideas what this spot is for (see photo)?
Thanks.

it doesn't have a spin on filter, it has a housing with a cap, and a filter element goes in it.

Does that sound like a Gleaner engine?
Did Gleaner engines have different heads on them originally?

The engine with a plate on the side is a 201 WC-WD engine. The 45 engine did NOT have a plate. Why not tell us what the engine number (not the tractor number) is and then somebody night be able to tell you what the engine came out of.
The last WD's produced had the 201 engine(with a plate)with a curved shifter. I don't know when the break for he tall head was but the head differences wouldn't make any difference in power.
By the way what is the tractor serial number?

The head could make a difference if it has dished pistons with the short head the compression will be lower. If I remember right the 201 was a combustion chamber in head design with flat top pistons where the 226 was comustion chamber in piston design with a flat surface on the head. So if some body put a 201 head on a 226 it would lower the compression.

1938 B, 1945 B, 1941 IB, 1949 C, 2 1938 WCs, 3 1950 WDs, 1951 WD, 2 1955 WD45, 1957 D-14

So, if I understand you correctly, a 226 tall head on a 201 will increase compression? That is the combination on my WD, I replaced oversize pistons and sleeves with standard bore (because that is what I had) and used a D17 head, so I might have comparable performance to the oversize anyway? Hmmmm. Sometimes dumb luck is as good as good planning!

If it weren't for the last minute, I wouldn't get anything done!

Block serial number should be on the carb (left) side toward the rear. Mike

1981 Gleaner F2 Corn Plus w 13' flex
1968 Gleaner EIII w 10' & 330
1969 180 gas
1965 D17 S-IV gas
1963 D17 S-III gas
1956 WD45 gas NF PS
1956 All-Crop 66 Big Bin
303 wire baler, 716H, 712H mowers

There is no combustion chamber in either head, they are both flat.

It doesn't mater what head you have as far as compression ratios. They are both flat on the block side.

Where it bolts to the clutch housing is referred to to as the rear flange.

This might help. On the left side of the engine right behind the carb is the engine ser #

like below. The top pic is a 226 out of a WD45 and the next pic is a 201 out of a WD. Don

3 WD45's with power steering,G,D15 fork lift,D19, W-Speed Patrol, "A" Gleaner with a 330 corn head,"66" combine,roto-baler, and lots of Snap Coupler implements to make them work for their keep.

Thats not the first one of them with out no's. with a fuel pump hole that is covered with a plate and no ser # this is not a Wd45 engine that came in the tractor new.

One more thing you can look at is the water pump mouting bolts are they 3/8" with a 9/16" head or 7/16" with a 5/8" head on them? Don

The waterpump bolts are 3/8" with 9/16" head.

What does that tell me?

too easy for you!

I'm the one here trying to figure out what mess I've got myself into.

I want as much power as possible, but not sure if I should locate a WD45 head and put on here or not.

I'll look for those markings Don.

The distributor is supposedly off something Farmall. Super B or something the guy said.So I know that isn't Allis original. I think the guy did it when he switched it over to 12 volt.

this Lerow engine, is it a bad engine?
What was it used in, tractors, industrials, ????

thank you for your comments Don!

It looked like a IHC Farmall setup and thats OK, the Leroy engine is a good deal too, they are just a different engine than the WD45 used. Im not up on them. Let us know.

I can see down between the box that holds the headlights, and the back of the block, and nothing stamped there either.
