I pulled a stupid. I changed the drive sprocket to an Andrews 34T on my 01 SE Road Glide. When torquing down the drive sprocket nut my torque wrench failed to click. I probably got up to 150+ ft lbs before I realized something can't be right. I backed it off to the prescribed 50 ft lbs. I haven't put the primary back on and everything feels fine when turning the shaft by hand. What damage might I have done? Any recommended checks before I put it back together?
Thanks

 

Could have stretched the bolt(s) and or damaged the threaded holes.

 

Get a new bolt. If it threads with no difficulty then the female threads are OK and you can torque the new bolt to the prescribed torque.

 

The nut I overtightened is the nut on the transmission mainshaft and pinches the drive sprocket between the drive sprocket spacer and the said nut.
I checked the threads on the mainshaft and nut and both are fine. My concern is I donlt know what else is on the mainshaft that might have been damaged by excess pressure when I overtightened the nut.

Thanks again.

 

I don't think you hurt the threads BUT you could take it off & check them out. If i were you I would check the threads & torque to spec. & just ride it. just MO

 

Wow,I should have read your question better.........NUT!

The only thing that I think would be damaged would be the threads.
If you can torque the NUT to spec,probly will be ok.

 

You're fine. Torque to spec. & ride it.

 

Get a new torque wrench.

Do you have a manual? As I have the same bike as you (2001 SERG) I checked my manual as I didn't think 55 ft-lbs could be the torque for a final drive sprocket.
The inital torque is 55 Ft-Lbs but then you have to scribe a line on the nut and sprocket and turn the nut an additional 30-40 degrees.
If I knew the pitch of the thread I could calculate the final torque but as torque varies with friction, that is why they use the method mentioned above. They use the same method for critical fasteners such as the rear sprocket bolts.

 

Yep 55 ft lb isn't nearly enough thats just the set torque then turn it another 30 to 40 degrees.I had to use a breaker bar and some pipe just to get 30 degrees.Is the nut around 2 1/2 inches
