Cluch bolts torque?
« on: May 01, 2011, 04:45:54 PM »
What is the proper torque for the 6 M6x25 bolts that hold the clutch on?

I'm using the Clymer manual to do this and it said 23Nm.   I tried that twice and snapped the head off two bolts.  

I know this is sort of a general manual for many years...maybe the R65 uses smaller bolts?  

This project has been stalled and I was finally making progress...  :(


thanks

I think that the 23 ft-lb figure is for the M8 bolts which are used on the later version "clutch carrier" design.     I seem to think that the proper figure for the M6 bolts would be in the 15-16 ft-lbs range, someone may likely correct me - I've got to figure this out eventually too as I've got a 78 R100 that has the similar older-style clutch, too.

I did a little searching...which I should have done first.  This apparently is an undocumented spec.    I went out and found a sheets of specs for various bolts and hardware grades on the google.  I ended up using 10Nm which is about 7.5ft/lbs.   Seemed a lot better.
