Serpintine Belt Alignment

[Blueox01 135]

My belt rides towards the front and eats into the tensioner,I've replaced the pully(not the tensioner) but only does this w/AC belt,I have non/AC belt that seems to run correctly,but for the life of me I can't see how to adjust the AC compressor since there is a roll pin that has to align in mounting bracket.

Most likely the tensioner is the cause... You might see more wear damage to the tensioner after its removed from the truck. I pulled one off a Ford Powerstroke and you could see it with the belt on, but now take the belt off it was fine. After removing you could see the shoulders of the tensioner where wore out and causing it to rock over. But I think the Non A/C route puts less belt face on the tensioner... (Gotta look at the label on my truck)...

Yes it has wore into the tensioner,but I thought replacing the pully would eliminate that,going to replace the tensioner and belt and go from there. Thanks Mike
