Belt Eater

[Lyrik]

Hey everyone!
I am hoping to find some answers to help me iron out some of the issues with my truck. She is my first diesel so please forgive my naïveté and bare with me.
My truck is a 1993 F-350 Ambulance Package, former animal control unit for the Las Vegas, NV police. It is a 7.3 IDI non-turbo. I don’t know a lot about the service history of this beast.

But I do know she has been shredding serpentine belts like it was a chew toy. Last time she did this we had just put a new belt on and within 75 miles, she shredded it and left us on the side of the interstate.
I’m trying to figure out why she keeps doing this. I have been told it may be the wrong tensioner assembly or even possibly something with the wrong alternator but nothing really telling us why or where we should specifically look.

If you need more info, I am happy to provide whatever I can and any help is MUCH appreciated!

Check all pulleys for bad bearings, check your tensioner, that it's still strong, and check pulley alignment. Those three things can cause a belt to shred.

First make sure you have the style ford mounted as new,the mounts are different thru the production run.
Then
Try the enclosed housing type, with the shock you will need to cg brackets tho.

Count the ribs on your belt and count the ribs on each pulley to be sure they match. Check pulleys with a straight edge to be sure something isn’t out of alignment. Check all bearings for wobble and the belt tensioner for constant tension.

The tensioners can wear out and actually push the belt toward the front of the truck. That makes the belt put pressure against the front of the pulleys and that will shred the belt.
