Frequently Asked Questions
Do I need a gear kit or a gear and sprocket kit?
If the drive gear is stripped but the sprocket and shaft are fine, the LiftMaster 41A2817 drive gear and worm kit is the lower-cost fix. The 41C4220A is the complete chain drive gear and sprocket kit for LiftMaster and Chamberlain chain drive openers made after 1993: helical gear and top hat assembly, worm gear, wear bushings, grease and hardware.
How do I know if my opener's gear is stripped?
If the motor runs and you hear grinding but the door and trolley don't move, the drive gear is likely stripped. If the opener only hums, check the capacitor, springs and door lock first.
