Clutch Drum

[koko64]

Noticed my Vee Two billet clutch drum has a loose base flange (the pressed on ring that supports the two plain steel plates at the base of the clutch pack). My concern is that the base will break off allowing the clutch pack to collapse. Is this repairable?

I ran a stock drum then tried out another Vee Two drum I bought from He Man years ago. The drum had a broken post, so I knocked off the opposite post with a percussion mallet and cleaned it up. I fitted TPO springs which were the stiffest spares I had and used shorter bolts to preload them.
Hasn't slipped yet but I'm curious as to the availability of even stiffer springs. Anyone know a supplier?

Testing the bike with a mountain ride, I noticed the clutch is smoother and note that the tolerance fit of the drum spline to the plain plate teeth is closer than with the OEM drum. Clutch is noticeably quieter too while using the same basket and plates.

That base flange looks like it could slip off.  Is it steel?

I'd be proactive. Remove the sleeve and reinstall using Loctite 640.

I used that on some tractor lift arm bushings that were spinning in the top cover and the problem went away.

Thanks you blokes.
The material doesn't draw a magnet and doesn't ring when tapped with a screwdriver. If I get another alloy drum I would want a one piece unit machined from one block. The oem drums are the same but that's understandable being cush drive, multi piece components.
