Default Reusing sprocket mounting screws?
Found this message on the instruction sheet of the new sprocket I am putting on the new Reaper Wheel for my 2008 Fatboy. It appears I cannot reuse the sprocket mounting screws that were in the old (original) sprocket on the Fatboy.


"Do not re-use sprocket mounting screws. Re-using
sprocket mounting screws can result in torque loss and
damage to the sprocket and/or belt assembly. "

Don't re use the bolts dude. If you do there is a high possibility that they might back out on you while you're riding (regardless of how much you toque them down).

Replacements are cheap.

Will not reuse them. Does not seem to make sense but if the HD document says do not use them as well as others, not going to chance it. Will get new screws.

I don't get this. Why can't you reuse a sprocket bolt? I need to pull my sprocket off to change the wheel bearingsl. I have a chrome sprocket cover and chrome bolts. The chrome bolts are $30. You mean to tell me I can't reuse these or my sprocket will fall off? WTH?

whatever floats your boat.......never changed the bolts on my jap racers and some were over 200hp .....on my second NT and have yet to see a bolt failure on any bike I've owned . chase the threads , use the blue Loctite and torque to spec ......that's all .

That sucks that they would back out

It sure is interesting...what would a new bolt have that an old one doesn't? They don't wear, they are the same size and pitch...why would the instructions say to toss them and put new ones in, other than the obvious....profit. There is some science here that is over my head. Is it because they have locking teeth on the head? The chrome ones I have are just chromed hex head bolts with a chrome washer, nothing more.

SDozier, do the bolts on the old sprocket look like something special? Thread forming or something?


We need Bill Nye the Science Guy on this one...lol

"Torque-to-Yield" bolts should definitely not be re-used, but these do not look like "torque-to-yield" bolts.
