Clutch Cleaning and Refurb
6/19/00
A couple of weeks ago I was complaining about my dreadful clutch, hardly disengaging at all, grinding 1st and 2nd gear teeth... I found out that it was plain adhesion causing the stickyness!
I took it all apart and performed the following work:
- Meticulous filing of all edges on friction plates, steel plates,
hub & clutch basket
- Light sanding of old friction plates (thickness after 60k = new
value) with automotive 120 grit paper to get rid of the glaze
- Medium sanding of steel plates with 80 grit; cleaned everything
with turpentine
- Mounted steel plates 180 degrees turned, so that rounded edges now
face the crankcase
- Added 0.070" shims to springs (yes, I've got strong hands)
- Treated new gasket with PAM Spray (both sides)
The result is amazing; the clutch works almost like new. Works out my
left hand too. Total investment was several hours of labour plus one
cover gasket. Actually, I had to use hammer & chisel to knock loose
the 27 mm nut.
One more tip: once you have that side cover off, don't miss the opportunity to clean the inside of the metal piece behind the oil level window!
