Changeing clutch plate on 50 Cub

Farmallb · Jun 4, 2015

I have moved to a transisionary place, and do not have the room to put alla my machinery here, so my SIL let me put it on a part of her property. My nieces husband took my 50 demonstrator cub although I had a 48 H, a WD AC, and a 60 DB there, and tore out the clutch trying to move a 1 1/2 ton truck I had given him for the use of his trailer.

QUESTION. What is involved in replacing the clutch plate, and is that all I need to replace.

You have to split the tractor right behind the engine. It is always best to replace the pressure plate disk and throw out bearing plus the pilot bushing/bearing

The biggest nuisances are that you need to unhook the hydraulic lines and have to remove the hood/tank. Wedge the front axle so the front half remains upright.

The available pressure plates and (especially) throwout bearings are lower quality than the originals. I recommend inspecting and only replacing if needed. When assembling, adjust the finger heights on the pressure plate. They will not be adjusted out of the box.

If your rear main seal leaks, you may want to fix that while you are at it. That is more involved than just stuffing in a new seal.

There are numerous discussions and how-tos on these tasks at www.farmallcub.com. I recommend you check there for details.

Here is a splitting stand that I designed to fit the CUB LowBoy and the Farmalls A, B & C series of tractors. Sure works nice

My problem is, I have NO concrete floor OTHER than in the house lol. I will lay a 2 X 12 by 10ft down the middle of the engine length ways. Ill put a floor jack on it and raise the back end of the engine with it. ill wedge wood wedges on either side of the sides where the engine fits to the front axle. Ill tie the jack to the front axle, then with a cable come along tied to another tractor, pull the engine forward enough to work on the clutch,
In reassembly, Ill pull the jack back by hooking the come along to the drawbar with the back wheels wedged at the ground. Ive done that before with a 34 CC Case.

My experience has been that it is generally easier to leave the front in one place and move the back half. Larger wheels roll easier on an irregular surface. Especially if you have a helper. You can each grab one rear wheel and turn it.

Your circumstances have to rule. So do whatever works for you.
