LiftMaster Gear & Sprocket Kits
Over time, the internal gears inside your LiftMaster garage door opener can wear down, causing the motor to run but the chain or belt not to move the door. Replacing the gears is a cost-effective way to restore your opener’s performance without replacing the entire unit.
Below are the genuine LiftMaster gear and sprocket replacement kits, which typically include the drive gear, worm gear, and bushings needed for repair. These parts are compatible with many chain-drive LiftMaster openers.
LiftMaster Gear FAQs
How do I know if my LiftMaster gears are worn out?
If the motor runs but the chain or belt does not move, or if you find white plastic shavings inside the opener housing, the gears are likely stripped and need replacement.
Are LiftMaster gear kits universal?
Most gear and sprocket kits fit a wide range of LiftMaster chain-drive openers, but you should always check your opener’s model number before ordering.
Can I replace the gears myself?
Yes, with basic tools and mechanical ability. The process involves opening the motor housing, removing the old gears, and installing the new kit. Always disconnect power before attempting repairs.
How long do LiftMaster gears typically last?
With normal use, gears usually last 8–12 years. Heavier doors or poor lubrication may shorten their lifespan.
