Countershaft Sprocket Bolt Torque Specs?? Lock-Tite or No?

10 posts in this topic

Hey Guys

Got my new 14T front sprocket and "Hand Tight Installed" it.

I cant find a torque value for those 2 little bolts anywhere. Any ideas?

Also, do you guys use lock tight on them?

Another weird thing, now the chain seems way too big, when i adjust it to the "freeplay" specs, it is in the red zone on the adjusters! :worthy:

Its only got like 1300 miles on it?

Thanks

:D

just get them tight and maybe blue lock tight. I change mine all the time and they have never backed out on me but i do check them often.

I'd say no more then 8 to 10 ftlbs...blue loctite. ....

Unlike the 6mm fasteners that go in the aluminum engine block, the ones for the sprocket are going into steel. Ten ft-lbs is a good absolute max for 6mm bolts in aluminum. Fifteen is OK for the sprocket bolts. Because of the higher torque, I've never used loctite on those bolts. The rear sprocket is a different matter. They always seem to come loose without the loctite.

Are you running a non-ring type chain? They can wear (stretch) real fast.
