Got lucky! My earlier post showed a hole in the first reduction gear from the PTO gear rubbing through. Today I finally got a chance to dig into it and what happened was the bearing cover that holds the PTO input shaft bearing in place, had broken at some time and the bearing finally worked it's way out of the transmission case. This has been going on for a long time. The sliding gear was chipped. My theory is the sliding input gear was jammed into gear with the engine turning, making an impact load on the bevel gears causing the bevel gears to spread a bit putting an end load on the bearing and breaking the bearing cover. When did this happen? I don't know. It's been in the family it's whole life and we aren't hard on things.
Anyway, while it's part way apart I split the axle away from the transmission case to replace a weeping gasket. After it was split I looked at the PTO bevel gears from the back and everything looks OK. The shafts turn free and smooth. While it's this far apart I plan to pull the shifting forks and build them up.
Rock Valley does not have a first reduction cover and they were going to call around for me but I haven't heard back. The crack in it is pretty healthy sized. Anyway, I feel pretty good about it considering what it could have been. Jim
What I first saw after it crunched.
Broken bearing cover. The broken edges are worn smooth. I don't know where the bronze piece came from. I was in the bottom of the reduction cover. Everything looks OK with the clutch forks.
The way it is sitting now. Hope to have all leaks cured after it's back together (fingers crossed) I'll put a dial indicator on the crankshaft tomorrow to see how loose it is.
