Liftmaster 41c4220a Gear and Sprocket Kit for Chamberlain, Sears, Craftsman and LiftMaster 1/3 and 1/2 HP Chain Drive Models

Worked great easy to install

parts exactly what we needed. I did go online to download a youtube video to play while I installed. better than using the printed directions.

We replaced the gear in January 2018 and in January of 2019 it broke again. It is still cheaper than a new opener, but it does take about 30-45 minutes to replaced (partly because of where my opener is attached to the ceiling). Not thrilled that I have to replace it again but it is a plastic piece so what can you expect.

Came fast and is the perfect part! Fixed a friends when he didnt think it could be!

Parts fit, good instructions. If you are handy with tools the job is not to bad.

Fit right on

fit perfectly

Product came very quickly and was perfect! Works like a charm! For easy installation watch this video. We had it done in 1 hour! This guy is GREAT! https://www.youtube.com/watch?v=OMPFJcdyJk0
