Harmonic Balancer Problems After running my LS1 in my GTM a few times, I had some problems throwing off belts. It looks like the Harmonic balancer is about 1/2 inch off set from the rest of the pulleys. I am using the same balancer and ac mounting, but I had to relocate the alternator and a few other pulleys. My thoughts are that the balancer is not seated right, but I do not see how it can go on any further.
I am hoping someone can see from the pics what I might be doing wrong.
Huge Thanks

I have a C5 and I had to replace my harmonic balancer after 64,000 miles. I had gone 8000 miles and it's on it's way out again. I have an automatic transmission and I was wondering does anyone else have this problem? I had replaced it with the OEM part, is that the problem?

I work at a GM Dealer on the vette side and i have seen multiple balancers fail even seperate far enough to come apart and contact the power steering rack and yes the factory balancers SUCK we use a Dorman balancers and they seem to work great and I am a very strong about using factory parts also belts being thrown slipping squealing wearing prematurely is a very common result also if replaced make sure to follow proper installation procedures and a new bolt is required and proper torque methods and values
