Got new rotor and new bolts my manual says for a91 softail torque to 23-27ft pounds that seems low

 

.......

 

Does the manual also specify Loctite?

 

When I bought new bolts for my brake rotors (I was building new wheels), the bolts came with thread lock already installed on them. Combine that with the proper Nylok nuts and those rotors are on to stay.

FWIW, I consider all that hardware "single use". I replace it any time I have to remove a rotor.

Also, I tighten them in several passes, alternating back and forth (like tightening wheel nuts on a car). Less likelihood of warping a disc.

 

If you buy the HD bolts they will already have threadlocker on them.

 

Bolts no nuts its a cast wheel bought bolts at hardware store and yes I used locktite just thought 23-27 ft pounds seemed low

 

The bolts are in shear. If that's what the book says, that's what you need to torque them to. And don't forget the Loctite. Whichever one the books says to use.

 

That's as tight as I'd go for steel into aluminum. You can go tighter, but you'll be back on here asking about stripped threads and Heli-coils.
