It *can* be, if you want to risk it. Most people just spend the chump change and buy a new bolt from GM. Use the old bolt to get the pulley seated then use the new bolt for the final torque pass.

agreed. I have like 6 of them just sitting in my garage right now.

I would spend the $6.50 and get a new one. It is cheaper than having your pulley back out on you while driving down the road. Plus it is a stretching thread on those bolts. 190+ ftlbs will do that

Like I am suprised that you have parts laying around....

ive reused my stock one a few times..never had any issues...because i kept pulling the damn thing, i went ahead and just got an arp crank bolt...in the long run, ill save money with all the damn cam swaps i may do in the future..

Ive reused them in a pinch without issues in the past. However, I prefer to replace the bolt when ive got time to get the part. Its cheap.

i would seriously replace it. i had my asp pulley come out on me even after i put loctite. its not common but it can happen.. and if you really want a good bolt get a arp bolt.. its better.

I have had to pull my pulley off about 5 times to get the damn oil pump o-ring right and i just kept re using the old bolt. No problems yet. I check it about once a month and never has come lose.

I just bought an arp bolt. Solved all of the re-use problems and is much easier to install. Just one torque pass. no degrees crap.

well good think it hasnt come loose because if it does your pulley is going to start to pull out and when that happens it damages the crank snout and therefore putting wear in the bearings in the motor. i learned the hard way i hope you reconcider to put a new bolt it..

It can be re-used once or twice without any problems.

I took the motor apart four times in one year, used the same bolt and just ran it in with an impact gun every time. Bought a new one on rebuild #5.

Nopeyou cannot re-use it. its a torque to yield bolt which means it will stretch once its torqued down. at least for the corvette LS1 it is. im assuming they use the same thing.

Just go to your local GM dealer and get part #12557840.It's real cheap insurance for a wholesale price of $3.18.

Not exactly. All bolts stretch when you torque them down--but that stretch is all elastic. The torque specs are chosen to ensure that's the case. Picture the bolt as a spring that provides a high level of clamp-up to the joint. That spring action is what holds the joint together and helps keep the bolt from backing out. Going past yield means permanent deformation to the fastener and your spring no longer works as it was intended.

I changed mine, with the one ASP supplied, I would suggest you do the same.

I have seen, and know of more than a handful that have backed out on any ASP/March/Powerdyne-SLP pulley because they used the stretched TTY bolt 2 times. How can a TTY bolt not exactly stretch?
