Shreeking belt noise first thing in the morning
Not the way to start off my day. 
Tightened the belt until I could hear bearings and it would not shut-up!
Tried to use some belt dressing without success.
Pulled the belt off to check for a bad accessory. All the pulleys spun freely.
Tossed off the Gaterback belt and switched to a Gates full rib. No more noise!
Inspection of the gaterback showed that the pulley rib peaks were bottoming out on the belt. Belt was about a year old
