cummins belt linment
 

Ok guys did the cummins swap in to my 88 gmc crew cab , and put the high mount ac bracket on it and now with the new ac pump the belt dose not line up it want to ride off by one grove on the ac pump , is this a common problem and is the a easy fix ?

I've had a similar issue when replacing an alternator on a conversion with custom brackets. The new alt pulley came with less ribs than the old one so we just got a belt with less ribs and it was fine. That belt ran the a/c as well and the truck made it from Colorado to California, spent a year there and then drove back to Iowa with no issues.
