Maintenance Tips Keep pulleys clean: wipe pulleys with a soft, dry cloth to remove dust, grit, and buildup that can hinder smooth rotation. Check for smooth rotation: spin each pulley unloaded; if it feels rough, clean and lightly lubricate the bearing area (avoid excess oil near cables). Inspect bearings & housing: look for signs of wear, wobble or lateral play; replace worn components to maintain reliable cable travel. Examine cable seating: ensure cables run true in the pulley grooves without kinks or twists, which can accelerate wear. Tighten fasteners: periodically check that pulley attachment bolts and fasteners are secure to avoid misalignment. Protect from moisture: keep the assembly dry; wipe off water or sweat promptly to reduce corrosion risk on metal parts. Follow system manual guidance: always refer to your basketball system’s instructions for specific part service and replacement procedures.
