The first and 2nd are the drive cog slipped onto the engine

The 3rd is with it removed laying next to the mounting hole.

David if the drive is steel the compressor will have a key behind the drive  check it and make sure it is not sheared if so find a compressor they shear for a reason.


good luck

I installed the new compressor and it leaks copious amount of oil at the bottom near the hole that drains oil from the compressor back to the engine sump.  The instructions said no gasket sealant.  I didn't use any.  I haven't pulled it back off yet.  I don't think I boogered up the gasket upon installation, but I did something wrong.  Any ideas?  

Another two hours of dismantling and reinstalling coming up.  Arrrgh!

Edit:  Update

I went back in and tighten the nuts, I mean tightened as hard as I could.  The leak stopped.  The Installation instructions say 220lbs torque.  I did that much if not more.  

The compressor model number to crossover to the old number is now  Bendix 289941.  Compressor cost me $423, governor, 15.99, and drive hub 31.33.  Since I had to remove one bed to get this out it took me about 4 hours total to do the job.  Bought it all at San Antonio Brake and Clutch.

This compressor will recover from 60psi to 120psi in about 30 -35 seconds at hiway speed, from 105 to 120 in about 10 seconds, so I definitely had a problem with the old one.  It was taking about 60 seconds to recover from 90 to 120.

David, if the gasket was not a DD style gasket with the built in sealant ( orange or green etc) you need to use something I use aircraft Permatex


good luck

The gasket had orange sealant on one side only.
