6.7 eating serpentine belts

Has anyone else had this problem? I have a 2011 6.7 Lariat 4X4 that has 2850 miles on it and has gone through 3 serpentine belts. The first time it went to the shop i was told "it was a wiring harness" that fell into the belt and caused it. That resulted in a new fan shroud, belt and wiring harness. The 2nd time it was due to the fact that the "belt was routed wrong for a single alternator", and now that it happened again 3 weeks after re-routing the belt they finally called in a Ford engineer to look at it.

I went with the suspicion that a pulley is misaligned, but the dealer here hasn't noticed anything.

Cant wait till tomorrow when i get to look over his shoulder as the "determine what is wrong"

Got the message from the dealership today that the Ford Engineer showed up yesterday, and they neglected to call me to come down, but it appears the problem is the Crank Pulley is out of round. So hopefully the new one will come in tomorrow and i will get my truck back Thursday. Hopefully this fixes the problem.

I did ask it the pulley being out of round could effect the internal bearings on the crank. Am i being paranoid about that? Seems to me that some that is balanced and has a part that isn't rotation properly if could possibly effect the internals.

Update on the "out of Round" it wasn't what i was thinking. It was the pulley was bent about 1/2" Yes i did say 1/2". Pictures to follow. The original pulley was really think compared to the cast one they replaced it with. Hopefully i'll get those today to post.

All i can say is just keep an eye on your belts for any abnormal wear.

Crazy to hear that. Probably an isolated incident.

Here are the pictures, and yes the pens are 180 degrees from each other even if the picture doesn't look like it.

1st picture is the new replacement pulley,

2nd picture is the amount of "out of round" or i call it bent

3rd picture is the original pulley.

notice the difference in the amount of "beef" on the 2 pulleys
