FYI, I replaced mine with my wheel installation kits when I got my new wheels and chrome bolts for the pulley.
Statistic? I would like to see some! Exactly how many failures do you know of first hand?

man you replied to me, thus you asked for my opinion again. There is a thread on here every so often about bolts coming loose. I am not going to lecture you on problem solving. I can understand saving money by patching or plugging a tire, when it gets a small nail hole in it. All the guys who run out and buy a new tire because it is not safe, I wish would just ship me there old one. Just the cost of rotor bolts, is not worth the risk.
You sound like a broken record. We have already heard your opinion, more than once. I was simply stating my opinion.

Many people have pulleys coming loose here and ruining the wheel/snapping bolts. Not for anything I think that this situation, when experiencing it, sucks. I say avoid riding with loose pulley bolts.

Yeah, I read about bolts comming loose. I also read about them snapping. I'll also bet they werent installed properly either. Loctight and torque spec? Bolts that are torqued to spec and loctight properly applied dont just come loose. If they did, loctight wouldnt be in business.
I am willing to bet the factory manual states to replace the bolts because they factory apply the loctight to the bolts and by replacing them, there is no chance the installer will forget to apply the loctight.
Lecture? Could you give me one with more than "the book says so" We are talking about a steel bolt in an aluminum wheel/hub which do you think will give or stretch first? Maybe you should be replacing your hubs insted of your bolts? Something to think about while you are supporting HD by buying unnecessary parts.
I would really like to know more about these stretched bolts. Size, application, amount stretched? I doubt you have the equipment to measure the amount of stretch on a pulley bolt.

Also, the instructions that came with the HD chrome bolts (hardware store Gr.8 chrome bolts weren't any cheaper) for the pulley were "torque to 23ft/lbs, then turn 60° tighter. Isn't that torque to yield (i.e. stretch)?

Yes, but explaining it to him is pointless. Explaining that looking at a head bolt that has stretched does not take a set of calipers. Explaining I own several sets of calipers, but figure only a moron would waste his time measuring a one time use bolt, is also pointless. By the way I am not lecturing on problem solving.
Not to stir the pot, but I have snapped a steel bolt in an aluminum cylinder head.

Grind, I don't know what kind of spec you'd call that.
I do know that I've been a CNC machinist for 20 yrs. tightening & loosening socket head cap screws with allen wrenches, using breaker bars on them, etc. over & over & over on the same bolts. I tend to over-tighten things because I don't want them coming loose. I have broken allen wrenches & stripped the heads of the bolts & stripped a few threads, but cannot recollect ever breaking the head of a bolt off of anything near the size of bolts being used on our rotors.

My point is that it is not possible to "see" how much a rotor bolt stretches. They aren't long enough to provide enough stretch to be "seen" You must have good eyes.

Azgunner It does happen often. It just has not happened to me ever (thank God). One of the guys was regularly breaking bolts off and ruined 2 rear 9 spoke wheels. I do not know why this happens as I seen him use over amounts of Red Locktite and torque his bolts. Same thing happens over again. I personally think the problem is with him and his driving habits.
HERE is a posting about the same thing only started within a short time of this posting.

You implied the same thing in your statement, and it was meant as an insult, I just said it. As I said before, if you wish to reuse the same ones and your life is worth $10 then go for it. Mine is worth more. By the way, if you do not wish for people to reply then do not hit the quote button, it means you replied directly to me.
