1. The issue of clutch disengagement has returned. After replacing clutch complete, it later began to grind going in gears, so I used the Kroil on the tranny input shaft trick-parked on a steep hill, and it resolved it, meaning the splines or the pilot bushing were seizing.
Farmer Brown never notified me that it was grinding again, so he's been jamming it in gear for a while. Ouch! I adjusted almost all the free play out. I again put drops of Kroil on the input shaft splines, and it seemed a bit better right away. I will wait for it to creep up to the pilot bushing again, and maybe give it a second treatment. If that's really the issue.
On removing the clutch inspection cover to get at all this, I noticed bronze dust/shavings, which I identify as coming from the pilot bushing...where else is Bronze in the clutch?
2. When the clutch is fully pushed in, and in gear, there's a groaning and shuddering coming from the left brake area. The left brake locks up drastically when applied. I had replaced seals in the left brake/ham years ago.
----Any correlation in these two separate issues? I think it's two separate issues, and maybe the whole tractor needs to come apart.
