Massey Ferguson 135 input seal replacement

[Steady Eddy]

I am presently replacing the clutch on my MF 135 and noticed that the input seals are leaking. I have purchased new seals and would like to replace them while I have the tractor split. My service manual says that I have to also split the transmission from the differential in order for the pto shaft to move back enough to drop from the input shaft. My question is how far do I have to move the transmission in order for the pto shaft to drop and secondly do I need to take the transmission apart. Thanks for any advice you can give me.

If you have an eight speed transmission this is a piece of cake. If it's a six speed, different story. I'd say the distance between the the transmission and rear housing needs to at least a foot unless you are really good with your hands. I would need to have room to stand (or kneel) between the cases. The top part of the transmission needs not come apart. Shift cover, top shaft, gears and forks all stay in place. You have the manual, it (should) describe the process. Only the PTO shaft needs to move.
