Sears Craftsman Liftmaster heavy duty after market main drive gear replacement part #81B0045-50 PK is for all Chamberlain Group chain and belt drive openers manufactured from 1984 to present. This is just one of many of our Sears Craftsman Liftmaster garage door parts that we have in stock and ready to ship.

You can find cheaper drive gears made in China from recycled materials on eBay but why risk making the same repair twice to save a few cents? Drive gears made from recycled materials are very likely to fail prematurely. We use the best possible material and a modern manufacturing facility in Costa Rica with the quality standards of ISO 9002 and 14001.

Technical: The large, main gear has 32 teeth and is 2 3/4" x 1/2" wide, with a 1/2" bore (sizes are approximate). You MUST apply a low temperature lithium grease (NOT included) to each tooth of the new gear or it will shred within days.

Compatibility: Works with ALL 1/3 HP, 1/2 HP and 3/4 HP chain and belt drive garage door openers manufactured from 1984 to the present for these manufacturers: Liftmaster, Sears Craftsman, Chamberlain, Garage Master, Master Mechanic and Wayne Dalton.
