Review on Dorman 594 146 Harmonic Balancer by Paul Tucker

Went through two of these, both cracked after installation. I installed the first one and it cracked from the keyway to the bolt hole next to it. Called, agreed to return under warranty, got a replacement the next day. Installed, cracked in the same place. Took it to the machine shop and measured it down for 0.007 inches. Spend more money and buy a better balancer. The only good thing about the experience was the very quick return of Revain.
