Per a discussion on caimag.com, the torque spec for the transmission drive sprocket is way too high. The consensus seems to be that it should be 50 - 75 ft-lb.

I don't trust any of it now. If they got that one so far wrong, how many others are bogus?

120 is way too high. My Genuine James trans sprocket Nut stripped out at about 90 ft-lbs. When I get the replacement nut I’ll stop at 80 ft-lbs. Also not gonna use the book “wack special wrench with a mallet “ method.
