Folks,
I got a few minutes to take a quick look at the camper tonite before it got dark. I immediately noticed some burnt rubber and debris on the face of the alt. As I looked closer, I also saw that the washer on the slide bolt was broken and half of it was missing. A quick check of the tension showed that it was way to loose and as I pulled on the belt I could make it loosen up more. I pulled the bolt out and found it to be the wrong type of bolt. It was a bolt you would use to secure fenders on the body of a car. The washer had points that would have come in contact with the adjustment slide and cause to much torsion in the washer. When the washer snapped the bottom part fell out and not enough pressure was left to keep the belt tight. The belt tension backed off and wore down the belt. I located a proper bolt for the slide, replaced the belt and all seems well. ;-) So hopefully this problem was not related to the other belt problems my family had been experiencing. I weill follow up an email later if I don't have any more problems.
Thanks for all the suggestions.

It is absolutely essential that a V belt NOT bottom out on any of the pulleys. The service life of the belt will be dramatically shortened.
Put a thin line of prussian blue at the very bottom of each pulley and install the belt. Mark one pulley and the belt that touches it with tire crayon (usually yellow). Turn the engine enough to get one turn of the largest pulley, then pull the belt. If any part of the belt got blue on it, then that pulley is too wide.

Me too! I have a 1984 Itasca with a Chevy 454 engine (I think) that started burning up belts. I was in the midst of having some other work done at truck place since I didn’t have the proper tools or time to lift the rig to changes tires etc… Took it back to them three times with busted belts, each time they told me something new they’d tried. I don’t think we ever got to the bottom of it, we wound up buying a new RV around the same time. But I’m about to pull the old one out of mothballs and I’ve been wondering what the belt problem could be or if it’s finally fixed. I’m curious to hear your outcome.
