I have a TR25W basket case I finally finished getting back together. I took it for a test ride and about 5 minutes in the clutch ceased springing back.
I took the timing cover off and the mainshaft nut, which was new, had backed itself off and stripped some of the threads (of the nut). I did some searching and it appears lots of folks have recommended using loctite.
Before I pick up a new nut and get things back together tomorrow, I was curious if anyone had other suggestions.
Did the clutch hub come off the taper on the mainshaft or did the centre slide on the hub? You can grind the hub to the centre or you can clean it and use a little powdered chalk dust to help the tapers grip. On mine I used some blue loctite 243 on the treads and torqued the nut to the figure in the manual.
