ok, this shit sucks a**. I put a new (reman'd) engine into my cetnruion (streched bronco) and it is chewing up serpintine belts about every 500 miles. I checked the accessory alignment sevearal times, and even took everything apart today to get something to maybe line up better. I am checking the alighnment of the pulleys with a straight edge, nothing is grossly out of alignment (bout .030 at its worst) A new tensioner was installed before the new engine was started. THe belt is jumping on the crank and wearing off one rib at a time. The accesories do not have much room for adjustment at all, they are mounted with cast aluminum brackets, so no help there. any ideas?? Im tired of needing a $30 belt every month!!! As far as excessive thrust bearing wear, I HOPE that the shop that Ford subs out its engine remanufacuting to, would have some sort of QC checks to prevent this. I dunno, I am going to go but some shims for the crank and see if I can piss it off that way. That is the only thing that is not the same from the old setup. Any ideas on how to fix it??
