UD pulley bolt
You CAN NOT re-use the crank bolt. Its is a torque to yield and stretches. You have to get a new one, unless you have an ARP bolt which is not a torque to yield type. Most people use the stretched old bolt to get the pulley all the way on, then remove it and put a new one for torquing.
use the install tool (or other various methods that DO NOT involve the use of the stock or any other bolt to aid installation) then use a new bolt. be it GM or aftermarket. the old crank bolt is now a pretty paper weight.
one time use only, DO NOT reuse

can anyone help me out, im tryna get the UD pulley back on the crank snout but it wont even go on one bit. BTW i have a powerbond and its all metal so you think heating it up in the oven would do the trick? or how did ya'll make a longer bolt to push the pulley back?
I would post in your local room to see if anyone has hawk's tool or similar. Some people also make their own cheap $$ version using threaded rod, bolts & washers. Have to look around to find the rod though.
I just went through this ordeal with the powerbond. I ended up making my own pulley install tool with some 16x2.0 threaded rod, some big washers, a nut, and an acorn nut. I got a question though, when I torqued it down it went to 32lb easy, and went about 100* of the 140* really easy. The last bit it got really, really hard all of a sudden. Is this normal for these? The last time I did it it got to like 45* and became a total pain in the *** and I never even got 140*, with 3 people on the bar we broke the 3' breaker bar before we made it that much. I know my first 3 or 4 threads were pretty bad from trying to pull the pulley on with a long bolt, do you guys think it will hold fine?
