I pulled the front housing out of the transmission on an H I mentioned a couple of days ago.
The good news is, disconnecting the clutch shaft and pulling the front housing all came apart easily and was easier to do than I anticipated.
The bad news is, per the photo, all that is left of the pilot bearing is the inner race and part of the cage. Using a slim magnet inserted into various fill and drain holes, I fished out seven rollers and the one side of the cage. The ?lump? on the bottom right is what?s left of the bolt that holds the pilot bearing onto the main shaft.
I?m assuming pieces of the outer race, the rest of the cage, and the rest of the rollers from the pilot bearing are still somewhere in the bottom of the trans housing. The other two bearings on the input shaft are a bit rough, but intact. The gears look OK.
If I can flush the rest of the pieces out of the main housing by using either diesel fuel in a hand sprayer or shooting a power washer into the various drain and fill holes, and from the top where the belt pulley was removed, I?ll just replace the three bearings and put it back together. If it comes to it, I?ll pull the top cover to flush it out. I?d hate to have pieces of debris circulate in the gear oil and cause mayhem after the fact.
So far, this project has been easier than I thought it would be. For some history on the tractor, it had a growl in the trans but I was running my log splitter with it. Then last fall I was driving it and something made a ?cracking? noise in the trans, and it locked up and killed the engine. It would roll with the clutch blocked so I pulled it over to my shop with a tow bar. Just found time to start working on it a few days ago.
