If I remember right, the older machines did not have a case drain line back to the tank. So if the motor has any amount of wear on it the oil getting by the pistons will build pressure and blow out the seal instead of draining back to tank. Shouldn't be to difficult to install the line, the biggest thing is whether or not the center post is drilled and tapped. I believe they are Parker motors and last I checked, about 2-3 years ago they were still available from a hydraulics store.BDub,
I have went to our Cenex Coop (not sure you have one down there) and they cross referenced or matched the existing with a similar tire. We have a standard farm type tire you'd find on a wagon perhaps on the front (we foam filled them) and a standard one you'd find on the rear of a tractor (also foam filled). I can't answer the question on the hubs. I have been trying to find out for a couple of years if any of the drive motors from later years will work on my "76" model as I have one that is worn enough it won't hold fluid with new seals. Good luck
