I highly recommend you use a proper installer tool. That way you wouldn't have had any problems with the threads nor would you have had to put the pulley in the oven.

 

If the tool was available here back when I did my cam I would have done that 100%, it's the most foolproof method. Otherwise I use a longer grade 10.9 bolt to get the pulley seated and then switch to the factory bolt to get it on all the way.

 

The rubber ring holding your balancer ring to the hub and font main seal wont like anything being 400* near them

+1 for using the proper tool. Using crank bolts to pull a balancer on is asking for trouble

 

I agree with both of the statements here...

when you use a longer bolt to pull the balancer on, you are still running the bolt through the crank and run the risk of damaging the threads, as opposed to a puller with a stationary hardened threaded rod that uses a big nut and washer to pull the balancer on

 

Yeah, the threaded rod is ideal, but using a longer grade 10.9 bolt works very well if you dont have access to the former.

Also, I heated my pulley up in the oven at 250 or 300 degrees for 20 minutes. It didn't really help at all. Some pulleys seem to benefit greatly from heating whereas some dont

 

I tried heating a pulley once, that didnt work. Then I tried the longer bolt method, that didnt work either, pulled the threads in the crank. Yes sometimes it works and some times it doesnt.

Too bad no body can sell that inexpensive tool on here so fellow members don't run into this problem.
