shredding belts

[deerecrossing]

my 95 powerstroke keeps shredding belts. its one groove off on the crank pulley and rubs the back rib off against the cover.almost like the crank is too far out.anyone else have this problem? i dont know what to do.

Have you checked your idler pulley and belt tensioner? Pretty common for those to lean and cause the belt to run one rib off or more when the bearing goes out of them.

Check to make sure the crank damper is seated by trying to tighten the bolt. From the side, eye up all the pulleys/idlers to see if any are out of whack. As dhanna6powerstroke mentioned, the tensioner arms can bend causing the belt to skip groves and get eaten. Double check that all pulleys are either 7 rib (94.5-early 95) or 8 rib and you have the correct belt.

Im also having the same problem as deerecrossing. i replaced 1 idler and the tensoiner along with a dayco gold belt. it was running good for about 2 days then i heard the belt slapping. took it all apart and everything was tight and straight. replaced the belt and its still happening. all my pullys are good. need some help here!!!

My 97 was doing the same thing. After replacing the tensioner, it still did it. Turned out to be the Power Steering Pump pulley needed to be adjusted out about 2mm (I used a pump pulley puller). No problems since. Cheers!
