I have been offered a 1936 W-40 the seller tells me it has a red diamond engine installed,my first reaction was to pass on it as from what little knowledge I have I am assuming that this is a non original engine from a truck or other application, is this correct or was a red diamond a standard fit to later year W-40s. I am tempted to buy it but not if its too far from original.I seek your best opinion. thank you.

The W40 engine was a FBB-298 truck eng. same as used in a D-50/D-60 trucks. WK used the same eng. but with a 3 5/8" bore. 298s had a 3 3/4" bore.

The original engine in the W-40 series tractors was not a Red Diamond. The Red Diamonds were a truck engine with a counter-balanced crankshaft, a better engine, but not original. The quickest way to tell is that the logo on the magneto side of the engine will say International through the triple diamond logo, and the truck engine will usually say Red Diamond through the logo. The original displacement for a W-40 was 298cid. A Red Diamond can go as high as 450cid., obviously making a much more powerful tractor out of it. That's why it is very common to see this done. As for originality, of course it's not right, but it is very common. Hope this helps you out!

I believe that the W40's did use truck engines, but I can't tell you if the red diamond would have been original or not. If I had a chance to buy a W-40, I wouldn't be too concerned with 100% originality, it sounds like a good tractor to start with, and go from there.

Saw at least a half dozen W/WK40 tractors at the RPR last Friday. All had the same 6 cylinder IHC truck engine. Don't know whether or not it is the "red diamond" engine - perhaps someone else here will know.

Punch below for a side shot of a friend's WK40. Someplace also I have a closeup shot of the motor. If I can locate it I'll send it along...

Incidentally these tractors have a very pleasing exhaust note. Given the chance I'd buy one just to hear it run!

I think the engine is one of the early versions of the Blue Diamond.
