Absolutely awesome diy grigor.

I've got a compressor on my daily driver with a worn bearing.

I'm not sure if it's just the bearing that's worn, or if the compressor is also seized though. It's hard to describe, but the 'rest' of the pulley (the bit that's inside of the free spinning part when the belt is off). Is that part meant to be turnable by hand? or is it meant to be f'ing tight?

Also, how much does it cost for the work to change the bearing? You in sydney and know anyone that does the bearing by any chance?

In addition to the bearing, if it is seized, which is the part that's seized? can that part be changed alone?

The reason why I ask, is because I have a freind who got a compressor reco'd and it was $600. Bit exxy considering i'll need to get gas, blah blah on top of that too.
