Shimming Alternator
I recently installed an internally regulated alternator and notice a whistling sound at idle, slightly metallic almost. After some inspeciton, I beleive it is coming from the pulleys/belt being SLIGHTLY misaligned. I will post some pictures for you all to make sure, but would this cause a whistling/whining sound?
My question is this: Can i shim or use washers to make the alternator come forward 1/8th-1/4 of an inch? Is this safe to do, and if so where would i shim or put washers? The best I can describe without pictures ATM is it looks like this (only diagonally of course) WP and Ballancer is here I alternator pulley is here I Obviosuly I need them to be even I I Last edited by TheSeeker; 04-07-2014 at 03:57 PM.

Re: Shimming Alternator
Go ahead and shim, It's safe. Hard to suggest where without pics.

Re: Shimming Alternator
You can bring the pulley forward a little by putting the lock washer in back of the pulley instead of behind the nut.
