wd-wd45?

[Al Baker(pumpman)]

I looked at a tractor setting in a bone yard waiting to be parted out. Few little things missing, but most of her was there. My better half really liked the look of that tractor. Power adjust wheels, wide front. Said her Dad has one like that. Almost bought it from the salvage yard owner except I know enough to ask was it a WD with WD45 decals. It did have an engine with a plate on the right side. I was told this was a WD block. So how does a guy tell? What was changed?

All WD's had the plate on the side of the block. All WD45's had a curved shifter lever but the late WD's had a curved shifter as well. Tom

Few small changes. Biggest was a half inch more stroke. 226 cubes vs 201. One mote plate in the hand clutch. Couple other things. Functionally identical.

What complicates matters is that the internal parts of a WD45 engine fit in a WD block.

But if it has a straight shifter and a plate on the block, chances are pretty good that it is a WD.

Engine serial no. is on left side of block, WDs started "WD" and I think 45s started with "45. The plate is a sure sign of a WD-WC block though. Who knows what has been put into any block or what combination of engines and tractors may have been put together by now though.

Check the serial # of the tractor on the back of the differential housing (left of center vertical face close to the left brake housing). Once you post that number here you'll get more answers as to the tractor itself aside from possible engine swaps.

Plate on the side is a WC, WF, WD block, 201 cu inch. Internals can be changed, and if it includes the crank, can equal a WD45. Late 1952, at sn 126xxx, the WD got the WD45 constant mesh transmission, with the curved shift lever. Factory WD45 starts at sn 146,607...1953.

I can't see what the question is? Either WD or WD-45 should be reasonable coming out of a scrap yard and sound like what you are looking at isn't in terrible shape. I grew up on WD's and most of the time they are very dependable and lots of them around yet including parts machines. Once in a while when really pulling a plow or a heavy load it would be nice to have a few more horsepower but them WD's just don't give up. Lots of the parts came out of the same bin and are the same on the WD & WD-45.

A couple years ago I paid $375.00 just for a wide front for my WD-45 and while it came with wheels & tires it still needs some repair. Good to know all this information mentioned though as when negotiating price maybe can bargain a little if the sales person is kind of misrepresenting what he has for sale.

The WD-45 had a Syncronized Transmission...the WD was NOT..
 

[JMS/.MN]

Late WD and all WD45 had a constant mesh transmission...no synchronizers.

Correct, but amounts to the same thing in actual Use...!
