alternator rattle problems?
Hi everyone I have a 911 w/ 2.2 and the alternator is starting to rattle. It has a Bosh 55amp external reg. I removed the belt and the rattle went away. So I removed the alternator and fan from the housing thinking it might be the barrings. There was no drag or noticeable play in the shaft up down in out? I noticed that I only have 3 shims. 2 inside 1 outside. Reading the threads do I need 6 shims? All help is greatly appreciated.
Thank You Bob.

I had a similar problem, it's your lack of shims.
It can lead to all sorts of problems.... Info here: Pulley Shims, Wrong Config? My thread: Pulley alignment question |
