The Pulley roller was locked up and the belt was worn. While I had it apart I replaced the 4 drum rollers as well as the 2 Drum seals. Everything went well though the Drum Seals were a little difficult to put on. Needed 4 hands! NOTE - WHEN PUTTING THE SCREWS BACK IN THE TOP TO HOLD THE LINT TRAP ROLL UP A RAG AND PLACE IT IN THE OPENING! This will avoid many bad words once you drop one down the lint trap opening.
