The clutch pedal felt funny on this '51 so since it's torn down as far as it is, "may as well" split it and see what's going on. My suspicions were verified: Clutch fingers were only at 3/4". Clutch is otherwise like new, if a little rusty from the animal nest.
While I was in there, I noticed that the transmission input shaft seems bent, but I'm not sure. When I rotate it it seems to have a lot of runout, like over 1/2". If I supported the pilot end so that it couldn't swing, the shaft seemed bowed as it turned.
When I had the engine running, I did not hear any noises.
How bad of a job is it to change out?

Re: Transmission input shaft
Were you having a problem with the pilot bushing dragging before you took it apart? 1/2 inch doesn't seem that bad. It may be best to let the sleeping dog lie.

Re: Transmission input shaft
Don't know if there are any issues yet. I just got the tractor running two days ago. Couldn't drive it because the clutch wouldn't release.
Probably before I spend any money, I should push it back together and see what happens now that the clutch fingers are adjusted properly. Replacing the input shaft looks like a transmission split anyway.

Re: Transmission input shaft
You are correct there. When you said run out did you mean that the shaft will move forward and backward 1/2 inch or just that it wobbles sideways 1/2? If that is forward and backward movement the retainer on the shaft at the front of transmission is most likely installed backward. That much endwise movement will let pto slip out of gear.Matt Kirsch wrote:..... Replacing the input shaft looks like a transmission split anyway.

Re: Transmission input shaft
The pilot end of the shaft moves around in a circle as it spins, instead of spinning axially.
There's some endplay (fore-aft movement) but not an excessive amount.

Re: Transmission input shaft
That movement is normal, the bearing is not that precise, and that is a lot of shaft extending our the transmission.Matt Kirsch wrote:The pilot end of the shaft moves around in a circle as it spins, instead of spinning axially.

Re: Transmission input shaft
All righty then, back together it goes. Maybe tonight it will move under its own power for the first time in the better part of a decade.
