Do you guys re-use these bolts? If so do you apply red lock tight? Iirc there is a different torque spec for these then what is in my 09 touring manual (also I have s&s crank)? Thanks to admin coyote for referring me to the sticky list for the shimming process, Great info.

They are too cheap (and usually in stock) to even consider reusing them.  The manual says to replace them.

:up:   I keep those and some other fasteners on hand in the event I need to use them.

Regarding the torque specification, the instructions that came with my revised compensator kit call for 175 ft-lbs. In contrast my workshop manual calls for 140 ft-lbs for the hex bolt. Since I used a new Torx bolt, I simply relied on the lock-tight patch that came on the bolt but some folks will clean off that pre-applied patch and apply their own lock-tight.

Agreed, keep a couple new ones in your bolt box, and occasionally pick up some every now and then from the dealership when you visit.  Note that while some folks brush off the locking patch, I just use them as is.  Also, I always clean out the sprocket shaft threads to remove any old locking material and any oil that might have migrated in there.  Finally, I go exactly by the service manual method during installation.  Doing all of this consistently makes removing the bolt a not too tight and not too loose situation.

I reuse them.  Clean the threads on both parts , then use red Loctite.

A also heat them before I take them loose.  Lock patch or Loctite, I heat them all.  Takes a little of the chore out of turning them out by hand.

If that is a torque-to-yield bolt it should not be reused.

It is not a torque to yield.  Where did you come up with that.

Perhaps you are correct in that it isn't a torque-to-yield bolt. But the 25% increase in the Torx bolt stress compared to the old hex bolt is not trivial. So if the bolt is not at yield at the increased stress level it may be close.

Seems to me it's pretty much there based on the torque. xxx amount of stretch but not quite the yield part. They should be a one time use bolt, however although many will reuse it.

I believe it's one grade up from the older hex bolts. Grade 9, I think, not grade 8. More of a reason to not reuse it, if that's the case.

That bolt is the one thing I can think of off hand that's not ridiculously priced. Shocked me the first time I bought one, not worth not replacing to me.

I have reused the bolt, but only because the local dealer didn't even stock them! :wtf: I popped in to get a few parts and asked for the bolt and said they would have to order them, they did not keep them on hand. Now this was about a year or so after HD had release the new comp with the oil deflector. I couldn't believe they did not have them. Out of curiosity I asked the service manager what they do, and they said the reuse them. :nix:
I am an adult?? When did that happen, and how do I make it stop?!

Bought a new one today. I remember the torque procedures had something like torque to ? then back off 1/2 turn final torque to ?.

After backing off 180* tighten to 175 ft-lbs.

More people should actually read the contents of this site. There is a great amount of information here, and many (mostly FSG) took a lot of their personal time to put it out here for others.

Amazing. Thank you for posting those.

I asked for a new one a couple years ago and the parts guy asked me if I broke or stripped the original. I said no. Then he asked why I wanted a new one.

My dealer stocks both the earlier hex head & the newer  torx.

I bought two of the torx just to have for spares recently   It was less than $10

I've reused them many times, not had a problem ( yet ) .

Two for ten?  That pretty much equals zero dollars.
