Re: Alternator Pulley Issues - BBC
This is probably not your problem, but I'll leave it here in case someone happens to make the same mistake I did.
I had a similar issue years ago after installing the engine in my Chevelle - alternator belt squeaked like crazy, got hot, and flew off. After several attempts at tightening and replacing the alternator, I pulled off all the pulleys to clean them up. Only then I realized the problem was mismatched water pump and crank pulleys. I don't remember exactly which was which, but I believe the crank had two identical pulleys and the water pump had one large and one small pulley. Basically, the alternator belt was being forced to slip around one of the pulleys, got fed up with it, and decided to end it's miserable life by being chopped to bits by the fan. I swapped out one of the pulleys, and all was right again. |

This is the fan pulley. The first is the alternator.

Re: Alternator Pulley Issues - BBC
those arent exactly the kind of pictures we need although it does look like the belt sits in the alternator pulley pretty deep. is that belt always worn down?
we need some farther away pictures of all pulleys and belts. plus a top down view of them to see if the alignment is off. as many pictures as you care to take
