The belt should only contact on the sides,with clearance underneath.

Good eye for spotting the shiney pulley, but that was after I cleaned it on a soft wire brush. Wish I had taken a picture just as it came off the truck. In the blow-up photo the arrows indicate where the belt was riding. The belt that failed first had the segmented inside, old belt I carried as "spare" was solid back, and the eventual replacement was a new segmented inside gates belt.

One thing that I was glad of was that one of the shredds had the part number on it, because more and more parts store counter people can not find a part if it and application are not listed in the computer.
