Serpentine belt

[RCompton]

Anyone have any ideas why my friends first generation would be eating belts.

I would guess pulley alignment but don't know for sure. Maybe someone out there has another idea. Thanks.

I would agree with pulley alignment, however it could also be too tight or the wrong size belt.

It could also be bad bearings on ANY one of the pullies, or even more then one.



I'd pull the belt and check each pully for play, or at least check all of them next time it breaks... cheaper to do it before it breaks though!!



Here is a link to my 3rd gen serpentine belt breaking story--

If everything else checks out I would replace the tensioner, the bushing for the swingarm may be bad causing it to run crooked and make the belt jump over a groove.

I remember the first time I went to buy one of these from an auto parts store the belt they gave me was right length and width but did not have the right number of grooves.

I checked before leaving the parking lot and took back into the counter guy. He said "no way the book calls for that belt" I said come with me and I showed him. He said "OH" went back in and a older way more experience asked the problem told him. He said without even looking get him this belt number, it was the right one. YEA for older and experienced parts guys unfortunately losing them and the younger group are struggling!!!

Something to check just in case?

if its eating belts then im going to say: belt tensioner this happened on my 00' and my 92' you can take it off and it does not look like anything is wrong with it but when the bearing goes it will cause the belt to walk off the pulley's and get eat alive.

Had a similar thing I hung from the refrigerator when my 2 boys was growing up. But it said something like "Have you teenager move out and get a job, while they still know it all!!!!"



I suspect there are several of these all say pretty much the same thing.

Classic case of a bad tensioner. There is a plastic bushing inside of them that gets worn, when it does the tensioner twists and the belt starts to run off the next pulley. The ones on equipment are even worse, because of the dirt it will eat a tensioner up in 4-500 hours sometimes.

Put a new belt on, start the truck, and then shut it right off. Look at the belt and see if it is running off the next pulley.

Or put the belt on, and put a straight edge across the tensioner pulley, and get a shock.
