Back in '81, I installed a Phase 3 belt drive on my 45. It has worked wonderfully well all these years and I've only had to replace the belt once. As of lately I notice that the teeth on the clutch drum have worn down substantially, and it's starting to slip. The engine pulley still looks good. I did an internet search awhile back to try to get a new clutch drum, but it appears that Phase 3 must have went down the tubes, or I'm looking in all the wrong places. I don't really want to buy a whole new belt drive, but I will if I have to. I would rather just replace the clutch drum. Can any of you point me in the right direction on this issue?
