Hi all. Well I have the dreaded wobble of the harmonic balancer on my 99 vert. I picked up the Dayco power bond PB1117SS balancer, race version, an ARP bolt and a new seal. My question is about pinning the crank. This part comes with a slot, for a keyed crank which we do not have. I wrote to Dayco , and said that they have had quite a few questions regarding this, They said the best way is to key the crank, but money talks on that idea. They also said some guys have pinned the balancer to the crank, but ended up scoring the surface of the balancer surface and the end of crank surface so that the balancer did not sit square. Any of you guys pinned your balancers to the crank?
