putting a Farmall 300 rear case into a Farmall H

I know where there is an H that the original rear housing has a big hole in it. If I can I am going to do my best to fix this tractor. Let's say for the sake of argument that I had a 300 transmission housing. How hard would it be to put it in the old H? Would I be able to use the axle housings, the axles, final drive, the gears, or anything else from the old H?

Thanks!

I guess then the question is will it be worth it? Have you tried this?

It would really been helpful to have more information on the differences.

Thanks!

One of the problems with your question is you haven't told us whether you want a H with a TA or not. If you want the TA it is not a big deal unless you can find a 300 with a TA eliminator. Not likely on that score.

You can change the axles and axle housings but why bother. The rear frame will probably have those already attached. The frame lid will have to be changed and the H shifting forks installed. The motor will bolt up to the H center section but the center section internals probably won't be compatible with the 300 rear frame internals. I'm just guessing on that. Anyway you look at it, it is a hair-brained idea. You are probably going to have to give up the PTO.

I would never ask the question you are asking. I would get the parts books of both models and start figuring it out. But rest assured that what you want to do is something I would never do. I would rather put a TA into a Cub just for the heck of it. A 300 rear frame in a H is just too mundane. You won't get no 'r e s p e c t'.

This hole was patched, and it still leaks.
