• Do not assume compatibility based solely on the 6.57" size
• Verify that the pulley groove profile and width correctly match the applicable drive belt
• Inspect the associated drive belt, shafts, bearings, bushings, keys, spacers, washers, retainers, idlers, tensioners, and belt keepers for wear or damage
• Check the belt for cracking, fraying, glazing, stretching, slipping, contamination, or uneven wear

• After installation, verify proper belt routing, alignment, tension, pulley clearance, and rotation before returning the equipment to normal operation
