I don't like using the crank bolt to install the crank pulley. You can damage the threads in the crankshaft and then you will be in a heap of trouble. I was lucky enough to weld a bolt together and use that as an installer.
Your best bet is to find a bolt long enough with the correct metric threads to install the crank pulley. Take the bolt and cut off the hex head. Install a nut on the bolt, a thick large washer with a coating of antiseize on it then install it into the crankshaft with the pulley already in place. Tighten down the nut to seat the pulley on the crank snout.

That's cool you want to know. From personal experience when I didn't know any better I used to use the crank botl to sock down the balancer. Well I was installing a balancer on a forged crank 440 and I'll be damn if the damn threads inside the crank snout got stripped out. Lessen learned there by having to get a new crank (and associated bearings and down time).
Maybe it was just a fluke but I don't take chances anymore, they make the tools for a reason.

why would you get a new crank when you could of just re-tapped the hole?

good question but i don't take chances when it comes to high horsepower applications. A new crank only set me back $280 at the time. I would have to take the crank out anyway to tap it and figured it would be just as easy to take out the old crank and put in a new one instead of messing around with the old one hoping everything went alright. The cost to have a machine shop fix the crank wasn't worth having it repaired.

sorry dude, that just doesnt make sense.
you would rather spend $280 instead of paying the machine shop $50 to retap it?
its a very easy and simple process.

I took it as a sign to upgrade. I figured if I had to pay a shop any amount of $$$ then I might as well upgrade the crank so it woul dbe one less part I would have to buy for the next season. I just took the opportunity to spend a little money at that time and then when I bought new rods and pistons I wouldn't have to buy a new crank too.
That's just the way I do things, spread out the parts buying. Right now I have a new torque converter but am waiting on a transmission. I buy parts/upgrades as money becomes available. Sometimes the parts go rigth on and sometimes they sit for months while waiting for other parts.
