Thanks so much for posting this information. I knew there had to be something wrong when I read over 60 lbs for such a small bolt.

Mechanical engineers working with nuts and bolts know the torque figures rougly off the top of their head. They are proportional to the size, so that should give you a rough idea if there is something not to scale when comparing to the other fasteners torque amounts. Once you have a feel for the figures you will know if they are not in the ball park.

Correct torque is 43.5 per the manual on a stock sprocket, that may change on an aftermarket one. It dependes on the material the sprocket is made out of!

I just replaced my OEM rear sprocket a few days ago on my 06/600. My manual was correct at 43.5 ft-lbs. However, when installing new sprocket, the nuts were struggling to reach spec. I ended up shy of spec because 1 nut stripped and another locked up and started spinning the lug. :-/ So this time regardless of spec, mine wasn't able to reach 43.5 and especially not 65 or w/e ft-lbs.

I recently attempted to change my sprocket on my k7 600. Everything went well until it was time to torque the nuts. I have the original service manual and torqued the nuts to 67 ft-lbs....come to find out, big boo boo. I stripped one of the threads on the studs for the sprocket carrier. Im only concluding this because upon trying to remove the nut, it just continously turns and turns. Does anyone have any tips, tricks, or advice that might help me out in this situation?? Thank you very very much.

Oh my. Stupid manual. I just torqued mine, stopped at 60ft-lbs cause it felt like i was deforming the studs.

Just an FYI, I just removed my nuts from 60 ft-lbs with no damage to the studs. I think i might get aftermarket nuts though.

For those of you with aftermarket nuts on your sprocket... Make sure you check the torque rating for yours specifically, mine is only rated to 29.5 ft-lbs. 43.5, and especially 60+ would've destroyed them.
