Verify the pulley diameter, bore size, cable path, mounting hardware, and available clearance before ordering. Published ratings reflect the supplier’s test configuration and do not independently establish the capacity of the complete door system.
Inspect the lifting cable for broken strands, corrosion, abrasion, or flattening. Check the companion pulley, extension springs, containment cables, and attachment hardware for wear and alignment problems.
Have a qualified garage door technician secure the door and safely release spring tension before replacing the pulley. After installation, confirm free rotation, correct cable seating, and balanced door movement.
