I just had my 2nd clutch bearing failure. The inner race of the clutch plate and the freewheel inside just seem to grind those ball bearings to bits, and it's causing the whole thing to lock up and effectively bypass the clutch plate. I had to replace the clutch wheel on my other engine because of this exact thing, and now on this new engine the same thing is happening. Do you guys have this issue with your bearings grinding themselves to pieces? How can I prevent this in the future?
