The washer thing has been done, only caution I would give you is becarefull not to go to thick and overcompress the springs.

at 9.000 miles, IF the clutch is actually worn enough to slip, someone has used it poorly. I would look at the oil first, unless you know you tend to slip the clutch a lot & expect it to be worn out. The wrong type of oil will sure make them slip.


IF you do go with washers, be aware , the thickness of washers varies greatly & the landing for the springs is machined into the casting. A washer will sit on top of the machined area, causing each spring to be loaded differently. I stacked mine on a bolt & chucked that up in the drill press & used a grinder to "turn" the washers down to the needed OD.

I sorted thru a bunch of washers with the calipers before I found the ones with a small difference in thickness I wanted.
