Problems with Serpentine Belt Anybody else run into a problem with their serpentine belt jumping a few ribs on their cars? I have the alternator relocated up top and can't seem to keep the belt from jumping a few ribs on the power steering and crank pulley.
I bought a new tensioner last night and I am going to try that. Need to swap my pullies though. My old one is a bit bigger than the one that comes on the new tensioner.
Thanks
Patrick

The majority of the time when the belt jumps ribs on a pulley is that is not lined up with the rest. Since you have relocated the alternator, double check to make sure it aligned correctly.

When my tensioner went bad my belt would walk up a couple ribs. I got a new tensioner and used the pulley of a 3.8 supercharger because it has a higher lip to retain the belt better. Seems OK now.

Verdad Gallardo No, I don't. Do a search in here for pulleys, thats how I found it. It is slightly larger than the stocker, but not much.
The idler pulley having a higher edge is what stopped my problems. Mine would kick the belt forward every time I went over 8000 two ribs. I finally made a tensioner pulley with 3/8 high walls and all was well.

Those with their alternators relocated, what belt are you using? I got a new tensioner and installed it tonight. Unfortunately, my serpentine belt is now stretched and I need a new one. I'm thinking I might need a short belt. Thanks.
Post a picture of the bracket you are using. A friend told me to loosen my alternator from the bracket first and then bend down which was the opposite of what I thought was needed (I was bending it up) and the belt lined right up. I'm not at home to post a picture of mine. I thought I was going to have to modify and spend another $50 to fix it and all it took was a little patience and 15 minutes. The high lip pulley seems like a jerryrig to me. Seems like you would be putting a lot of tension on the end of the belt where it would rub the wall of the pulley. I would think that the belt would wear out prematurely/get soft on that side? Hey whatever gets it runnin' though right?
With my smokin hawk alt relocation bracket, I had to shim it out to get the pulleys to line up correctly. That was throwing my belt off a few ribs at a time, until it came off completely or shredded. No more problems after shimming.

I will get pics tonight. My bracket is a lot like Smokinhawk's bracket (whom I PM'd last night to see if he could send me one). I have the belt tight now. Got another belt since the last one stretched out a bit from being off a few ribs. It still squeals a little bit leading me to believe I don't have it quite tight enough yet.

The Katech manual tensioner will probably solve your problem. We have a KB LS2 truck here that slung belts like it was its job...if you watched the tensioner on the dyno it would fling around and then shoot the belt off.
Something to look at atleast...

It was jumping about two ribs off the power steering pulley and off the crank pulley. I got a new tensioner and installed it along with a new belt. Everything looks okay for now, just getting some squealing. I think the belt might not be tight enough on the water pump bell causing it to rub and squeal.
MM made my manual tensioner and I am using the Stainless works alt rel bracket with quite a bit if shimming and all is well since with stock belt and stock pulley. The shimming is what fixed everything for me.
