I have a noisy air conditioning bearing. I have removed the pulley and notice that the bearing seems to be locked in place at several places with what looks like peening. How can i remove this bearing and install a new one or do I have to buy a new pulley with the bearing already installed?

 

To remove bearing, take a small flat head scredriver and gently tap those indentations parallel (as much as you can) to the bearing, once those are undone put the pulley on two pieces of 2x4 and tap the bearing out using appropriate size socket. To install use same technique but use old bearing to tap it in. Otherwise you could take the pulley to a shop and have them press it in/out.

 

I need up buying a rebuilt pulley through EBay. Cost $100 but I did not have to uncounted the bearing and press a new one in. In the future I would just replace the bearing because the rebuilt pulley I got was really dinged up and I had to file it smooth (just the edges not the surface that the belt contacts).
