Rear sprocket nuts (torque value?)

A question for all of you guy's who have fitted a new rear sprocket.

Have you tightened the 'Final driven sprocket nuts' to the recommended torque value of 108 N-m (80 lbf-ft) as stated in the Haynes workshop manual and the Kamware.com site?

The reason I ask is that, that torque value seems to be rather high to me and was wondering if that was a mistake?

Cheers,

Chris.

Ive done the 80lbs... they'll hold it. I recommend putting the nuts on lightly, put the wheel on the bike and hold it with the rear brake, or put the bike weight down on it when tightening... it's a B**CH to hold the wheel and tighten unless someone is helping.

I thought the value was high as well...i think that the SV is around 50 ft/lbs....i read the value a few times, shrugged my shoulders and manhandled it.

Thanks guy's for your comments. It's reassuring to know that 80 lbf-ft won't shear the bolts!

Reviving and old thread...

My torque wrench was way out of calibration and I damaged one of the threads just enough that the new nut won't start nicely. Does anyone know what the bolt is so that I can get the proper metric dye for it? I don't have a metric one, and I don't want to get a set w/o the right threads.

you could just take the nut in with you to go get the dye and have them double check it.

I've repaired thread damage with thread files made by Snap-on.

Took a flange nut to lowes and went through their metric bolts. It's a 12-1.25 thread. Didn't help me since I cannot find a die that size, but I see that wheel studs have a seperate part number. I'll just replace the wheel stud.
