Systematic program of periodic inspections and corrective actions to maximize belt drive service life and prevent unplanned downtime. Key activities: (1) visual inspection every 500 hours for cracks, fraying, glazing, or unusual wear patterns; (2) tension verification using a frequency meter (sonic) or force-deflection gauge — retension as needed per manufacturer specs; (3) alignment check with straightedge or laser tool (max 0.5° angular, 0.5 mm/100 mm offset); (4) pulley groove inspection with a groove gauge — replace pulleys when groove walls are polished or widened beyond tolerance; (5) log operating hours for replacement planning. Clean oil and debris from pulleys. Replace all belts in a matched set simultaneously. Per Gates and Optibelt maintenance guides. Proper maintenance can extend belt life 30-50% beyond neglected drives.
