Drive Gear & Worm Kit - OEM Genuine Parts For Chamberlain Garage Door Openers 1984-Current

If your Chamberlain, Liftmaster, or Craftsman garage door opener is making grinding noises but the motor still runs, this drive gear and worm kit is probably your fix.

This genuine OEM kit includes everything you need - the main drive gear, worm gear, replacement bearings, and clear installation instructions.

It fits most Chamberlain-manufactured openers from 1984 to current models, which covers a huge range of Sears Craftsman and Liftmaster units too.

The 2 3/4-inch gear diameter matches the original equipment perfectly.

These plastic gears are designed to wear out before more expensive components get damaged, acting as a safety fuse for your opener.

The installation is very doable for most DIYers with basic tools - there are plenty of online tutorials showing the process step by step.

Much cheaper than replacing the entire opener and typically fixes that annoying grinding noise completely.

Just make sure to disconnect power before starting and take your time following the instructions.

Definitely one of the most common garage door opener repairs that can save you hundreds in service calls.
