[DeTomaso] Sanden Compressors noises

[Julian Kift]

In my experience it is rare for a compressor to fail, so being on your third I have to wonder whether the compressor is being over stressed somehow. Are the belts perfectly aligned? Not many people realize but the compressor brackets are sold in 1/4" offset increments to align different compressors.

I've got the Kirk Evans bulkhead reduction kit and pulley setup that drives
the compressor from the crank and the alternator from the compressor.  I am
on my third Sanden rotory compressor and this time I had new high and low
pressure switches installed by an AC shop.

With the compressor off, there are no issues.

With the compressor on, at 2,500 the brand new compressor makes a metallic
clanking noise.  This is the same noise that occurred before the last 2
compressors failed. The noise builds up and if you let off on the revs, it
slowly decreases.

Is this noise from over-revving?  Over pressurization?  Defective
compressor?

Any ideas welcome.

Thanks,

Rob
