Re: Weird belt problem
I got a new alternator fan today, about a 1/4 inch smaller. Put it all back together and took it for a test drive. Seems to be working so far.

Re: Weird belt problem
Everything appears to look normal, except.....the fan...wow, did that get chewed up!!! I have never seen an alternator fan do that.
And the back of the pulley seems to have a weird shaped wear pattern, where the finish is worn off more on the bottom LS of the pulley in the pic. Maybe nothing at all, but just seems odd. JMO, the only thing that I can think of, is that you have a bad bearing in the alternator, or maybe the tensioner is at fault as it was mentioned earlier. Therefore causing a wobbling effect that would have created your problem. again, just thinking out loud!!! I thought that the fans were originally black, your appears to be silver (the one that got all chewed up). Not that it means anything. But there has to be something somewhere, somehow that caused the fan to look like that!!! Good luck, hope the new blade works out for you, I would just keep checking everything after every outing to make sure it is ok... A side note, the only other thing I could think of is, if the fan was hitting the outside housing of the alternator on a continual basis for a long period of time, then that would most likely chew or break off a piece of the blade as shown. But then you would also have major wear marks on the alternator housing. Just another thought!!!
