Darn, been sick for a week, just getting back some energy. Spent a couple hours out in the shop, checking out one of the 129s. Last time, I noted it started and ran, so I pulled it into the shop.
PTO is shot, and head gasket is leaking, so I pulled the carb, hood and grill, and removed the head and PTO. Head bolts were barely tight and the PTO set screws came out easily. Someone had been into the PTO recently, the bearing looks pretty new. But they didn't tighten the jam nuts properly, so it came apart.
The engine is original bore dia, an unusual find, at least for me. Most I find are bored .010 or .020 over. Head fins were about 25% plugged with what looks like mouse debris, so cleaned that out. Now need to pull some of the other tins to see what else is there. Again, head gasket seems relatively new, so I'm guessing the head never got re-torqued or over heated due to the lack of cooling.
Planed the head, surfaced the PTO on the lathe, ordered the parts needed to rebuild the PTO.
Plan is to rebuild the carb, replace the head gasket, and run the tractor again to assess health.
The hydro valves are sticking, so I removed them and cleaned them up a bit, trying to get the buttons to operate. I put a pair of auto release valves in temporarily.
I don't see anything on this tractor that is not original. Who ever owned it took decent care of it. Well, except for the tunnel cover screws. those never last.
Pics of the aftermath...
