I've disassembled the pump (see picture) but I can't figure out how to get the front pump bearing out. I may just clean and lube, put it back in and see if it's quiet.

Here is what I've found so far.
Here is a thread that has some good descriptions, plus the pulley replacement bearing and the online place to buy them.
Air pump bearing
This place is local to me, and I was hoping to drop by and pick up the bearings, but they did not answer the phone. Website appears to be up, hopefully they are still in biz.
Here is the ebay guy:

There is some good info just in his ad. He does not have any current auctions. I emailed him with a few questions and he did not answer, you may have better luck.
Here is a current auction for a rebuilt unit:

He is local to me and if I get into a jam, I may buy this one.
Here is another thread I found with lots of detail:
Air Pump Bearing - SOLVED
I suspect that my vane carrier rear cover bearing is shot so I'll need one of these Timkin bearings also.
