      hey guys, I’m needing to take my clutch off and when I put it back on it says to use lapping compound to put it back on. It is a tomar td23-2 clutch.  Ive got the tools to take it off just never done it before.

      any advise when putting it back on would be a big help.

      thanks

      Bob,
      you should only have to lap the clutch once to insure the two tapered surfaces match. I’ve used a valve lapping compound from my local auto parts store.

      You can easily screw up the fit so, before you do anything test the fit, it might be ok. Put the clutch on with less than full torque and see if you can pull it off by hand with reasonable force. If not it’s a good fit. If you have to lap it don’t use anything course, you want 800 grit aluminum oxide or something similar. You want the taper to grip mostly on the big end so put a TINY bit of grit on the small end and work it in. Test often.
