Self destructing pully belts why? #1287651 08/19/12 02:04 AM 08/19/12 02:04 AM

I was doing a car show today and when I opened the hood I saw the pulley for the alternator had self destructed and torn it's self to shreds. Luckily it lasted till I got home, but the belt is only about 500 miles old. It basically came apart and unraveled. The power steering belt is still perfect and I replaced then at the same time. I was wondering if maybe over tightening it could cause this sort of premature wear?? The alternator is one of the aftermarket PowerMaster units Summit sells. It has been on the car for about 8 years and this is the first time i have had an issue like this. I use only the good Gates brand belts too. Any ideas??

I've heard that too That's a pretty subjective way to measure tension.... Is this a average guy twist, a Goldberg twist or some 12 YO kid twist? Are you going for a 1/4 twist with all your strength or a comfortable grab & twist...... Point is it could easily be to tight but with hands on experience you get a feel for what it needs... The proper way to set it is with a belt deflection gauge, good luck finding one.... Typically I go for about 1" of deflection in the middle of the belt when pressing with my thumb, but again, how hard do you press... As has been mentioned pulley alignment, pulley condition, other things contacting the belt or just a defective belt... I don't think Gates has taken production to China butttttttttt...

Well none of the local parts stores sell GATES brand belts in that size so i will order one tomorrow. I am doing a major cleaning now in the engine bay anyway.

Looks like you might have a bit of a misalignment. Also inspect each pulley to make sure there are no burrs that might be shredding your belt. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
