Torque problems while reassembling my clutch
I was having shifting problems with my '89 XT600, so I removed the clutch for routine maintenance, and when doing that I noticed that the clutch boss nut came off without a wrench. Other things were loose too, but not as bad, so I figured that this looseness was the reason for the shifting problems.
Anyway, as I'm reassembling it, I tighten the clutch boss nut to the torque specified in my manual, 51 ft lbs, and I notice that the clutch boss and the primary drive are bound, essentially rendering the clutch useless. Taking the clutch boss nut off cures the problem, so I finger-tighten the nut. If I tighten it so that it doesn't spin freely (about 2ft lbs), the clutch boss spins freely. If I tighten it as tight as I can with my fingers (maybe 3-4 ft lbs, I don't know), it binds up. It will still spin if I really grab onto it, but there's very noticeable resistance.
Is there something wrong with the clutch, or might something be out of spec? If so, what could it be? Or should I just give up and finger-tighten the clutch boss nut and count on the lock washer tabs to hold it in place?
Any help is appreciated, thanks.
