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

Fits perfectly the 18 year old Craftsman 1/2 HP opener I have.

Worked perfectly, thanks.

Worked perfectly installation was complete with parts included.

Product as described good value and great shipping. Fit Sears opener perfectly.

I installed 2 of these kits with my brother in an afternoon due to sagging chains and bushings that were completely worn out and broken. The kits had everything we needed for perfect replacements. After installation, we had to readjust the chain tension and door closure, which was simple with both of us.

A full replacement, works well. Took about 2 hours as some of the screws and bolts were hard to access.

I think this is the second one of these I have purchased and installed in different garage door heads. They fit and work fine. They are not hard to install if you are handy at all and dont mind taking apart your garage door opener head.

Worked out great

Part arrived and fit right in. Garage door is now working.

Fixed my own garage door opener for 22 bucks. Cant beat that.
