I have the compressor on the bench it is just like the one in Chessies pics, I will try to make sure it is slipping while I hold the compressor from turning as Dan suggested, If is is slipping whats my next step? Do I remove the cotter key and nut to remove the drive? John.

I got the drive removed, looks like it was slipping, hard to tell by looking but I could see it moving between the fiber and the steel! I will call Luke Monday and get parts ordered! Thanks again for all of your help, I greatly appreciate it!! John.

Finally after a couple of months I found the problem, I had an air leak on a electric tank drain valve ,I could not hear it with the engine running, I finally hooked up shop air on the big line at the compressor, with the engine off I could hear a flutter, I replaced the valve and built air pressure right away! So I replaced the gear on the compressor and the air governor, A good trouble shooting experience. Thanks to all of you for your help with this issue. turned out to be an easy fix!!

What brand was the leaky one? Did you replace it with the same brand? 
Wondering changing spring loaded to electric.

actually I replaced it with a manual valve for now, not sure what I want to use for a permanent valve ?
