Hi all. I purchased a used set of SM-Pro (Rugged Roads) rims for the AT. I wanted to replace the studs and bolts on the rear drive hub fo my installation. I had an incident today where one stud backed out and seriously scored by swingarm. I can't believe it backed out, yet you can see loctite (blue) on the threads. I looked through the shop manual and can't seem to find torque values for those rear studs. I've tried contacting RR and SM Pro.

Studs are 90102-MAS-000 12x25 the only reference I’ve seen is the spec for a same size bolt in the shop manual, they sell the studs but torque values seem to be a state secret.

Yes, I agree. Can't find those specs anywhere. Long side of studs into hub so sprocket sits on unthreaded shoulder. Nuts are 100nm but I cannot find stud specs anywhere. E-mailed RR and SM-Pro, who make the hubs. :unsure:

If a torque value for a specific nut/bolt is not given in the shop manual then it should be tightened to the torque specified in the standard torque values table, usually located in the first chapter.

Appreciate the reply. I don't think 54nm is enough for such an important part of the drivetrain. The damage was caused by one that had broke free. The nuts are 100nm. :unsure:

If you torque a nut onto a stud, does it not stress the stud as if it was a bolt, to the same value? What's the issue? Just Loctite it again and make sure to torque the nut properly.
