Thread: Alternator Bearing Removal & Squeek!

Your heading says alernator, but I will reply for the AC pump as in your question.
It might be tight but once you have everything undone try gently tapping it forward with a nylon mallet or soft copper/brass hammer. Might spray in some penetrene onto the shaft too. Once you have the pulley off, you will need to grind off where the bearing is peened in, then press it out. Re-installation is reverse, re peen with a sharp punch. The bearing shop may tell you that you cannot do this (or they did to me) but it works well. The bearing you should need, for a 300 TDI is: NACHI Bearing, full number on the box is 30BG5222-2DSE - this is what it is fitted with from original - SKF number is 30 BG5, should cost $35 - $40 +GST

I tried it and failed I used a rubber mallet and I was hitting it from behind the pulley wasn't a lot of clearance but it budged a little ...though don't know if I was doing it right, looks like I might have to show it to my mechanic and see what he can do
