I have my clutch apart yet again. 3rd year in a row. 1st time: bearing in slave cylinder disintegrated. Replaced everything: clutch pack, slave piston, bearing, spring. 2nd time: new bearing blew up. 3rd time: clutch started getting grabby, wouldn't take a load. Opened it up and it's all dirty, like messier after 1 season than it was after 25 seasons.

Started taking it apart thinking it's an oil seal. Entire clutch is out (basket too) and I realize the mushroom pin looks distorted, and doesn't really turn - so the bearing is seizing. Also notice the inside of each of the friction discs in the pack is kind of chewed up, and there are marks on the clutch gear. So now I wonder if the slave piston is getting misaligned or something? Is that possible?

I really don't know what to do at this point. Should I dig further and check the oil seals since I'm almost there? I'm going to order my 3rd slave piston & bearing in as many years, but I really don't want this to become part of my yearly maintenance ritual.

Help?

Seals are cheap and easy to do and are about the only place oil can leak into the clutch . Are you fitting the modified 900ss slave piston and skateboard bearing ?
