A worn belt will ride in the bottom of the pulley. Replace the belts if any of these conditions exist. Replace the belts if the belts are stretched beyond the limits of the adjuster.
Note: If new belts are installed, recheck the belt adjustment after 30 minutes of operation. If two belts or more are required for an application, replace the belts in belt sets that are matched. If only one belt of a matched set is replaced, the new belt will carry more load. Belts of the same part number are not necessarily matched belts.
