The drive gear in my 22 year old 1/3hp LiftMaster was totally destroyed and dropping in the full Sprocket/Shaft/Gear assembly from the 41C220A kit was an easy fix that returned my opener to perfect operation. I especially appreciated having the detailed instructions that accompanied the kit. The Part 1 "Preparation" section and Part 7 "Reinstall Chain/Belt.." sections of the instructions helped avoid the trial and error of adjusting the chain for proper operation after install. I would also add that the ordering, purchase, and quick shipping service of OPEN DOOR was super smooth.

I recently ordered a replacement gear & sprocket, the product fit perfectly in my old Craftsman garage door opener. Not only that but the shipping was free and FAST!

Item arrived two days after order which was a day earlier than projected. The gear and sprocket fit perfectly and presented no installation problems. My worm gear didn't seem to be worn at all so I saved those parts for later possible use. I couldn't have been happier.

The replacement parts for Chamberlain/Craftsman door openers are pretty standard. Open Door Enterprises sets themselves apart with reasonable shipping costs and personalized follow-up. My part was shipped USPS with tracking. When my local PO delivery went to the wrong address, Customer Support email walked me through the process until I got my part.
