Hey

Anyone have a problem with the harmonic damper pulley on the crank shaft causing auxiliary belt damage?

I have been battling a screaming aux belt problem for weeks now. after replacing the tensioner and both idlers as well as the alternator and power steering pump (basically everything except the AC compressor my shop is now telling me that the harmonic damper mounted to the crank shaft is causing damage to the edge of the auxiliary belt.

Thanks

It is just a vibration reducer, not a harmonic damper. A harmonic damper has a flyweight of some sort.
