Charging ROTOR Torque

[dubepj]

Charging system not working so ordered a new Rotor. Not sure what torque to use when installing new one. Nut size is 17mm and bolt size is 12 mm, looking at on-line manuals I get some that say 33 ft. lbs and some that say 40 ft. lbs. Please let me know what to torque that nut. I have stripped tread in the past so now I try to be careful. Thanks a lot.

My 78-80 Yamaha manual says 28 ft-lbs. I usually put a little grease on the taper shaft and threads, use a new lock washer and go about 22-25 ft-lbs.
