I'll take the other 3 ....... doh! The checkbook says that I get none.
The common RD450 in the truck application included a 2 bbl. carb with a 4'' exhaust. The exhaust outlet on the FBB 298 kerosene manifold is 2 1/2" ID plus other internal restrictive cast webbing used on the heat riser mechanism.And if I do go with a Rosewood manifold, are the gonna be two small to let the 450 breathe like it should?
The only F&H rear wheel listed in the W-40 parts book (TC-19) is F278 which is the one piece round spoke rim. It may be possible that the F&H wheel combination that you have was a rubber tire option for the late 22-36's. The axle sizes between the two models are the same.Did F&H offer these just for the 40, as a steel-to-rubber conversion?
The Red Diamond engine was a popular IHC heavy truck motor.What model trucks did the RD450 engine come out in?
Eric, yes these are split rims. Attached is a close-up.Bahart - Your cast centers are even different from my F&H cast centers. Mine have no casting number and the F&H is stamped rather than cast into a flat place on the hub. The part number may have been there at one time but rust has long since helped it disappear. One other difference is that my F&H cast centers take full drop center 8" x 32" rims. Yours appear to take the semi-drops like those used on the standard 40 cast wheels. Interesting. Even with all of these tractors I have and have seen, I learn something new all the time!
