Garage Door Opener Gears - Replacement Kits - Sprockets
Garage door opener gears and sprockets transfer power from the motor to the chain or belt. When they wear out, the motor may run but the door won’t move—or you’ll see white plastic shavings inside the housing. Replacing the drive gear, worm gear, or gear/sprocket assembly is an affordable way to restore smooth operation.
What to order: Match by your opener’s brand/model number (motor head label). Many chain-drive units use a drive & worm gear kit or a gear/sprocket assembly. Always verify compatibility on the product page.
Safety: Unplug power before servicing.
FAQs – Gears, Replacement Kits & Sprockets
How do I know the gears are stripped?
The motor runs but the chain/belt doesn’t move, you hear grinding, or you find white plastic shavings inside the opener.
Do I need a full gear/sprocket assembly or just the gear kit?
If the top sprocket or shaft is worn, use the gear/sprocket assembly. If only internal gears are worn, a drive & worm gear kit usually suffices.
Will these kits fit my opener?
Check the opener’s brand/model number and match the kit listed on the product page.
Is this a DIY repair?
Yes, for a careful DIYer with basic tools. Open the housing, remove the worn parts, install the new kit, re-tension the chain/belt, and test.
