Good price, works good and fit, but next time I would order the complete gear and spocket assy.

Open Door Discount Remotes made the repair of my Liftmaster easy and stress free. From the search of the parts I needed to the installation, I didn't find but one issue with my experience and that was my old eyes couldn't read the included Install Instructions. Even that was an easy fix with the downloadable set of instructions.

Sears Craftsman 1/2 HP chain driven garage door opener manufactured 1995. Drive gears that this item replaces were literally chewed up when garage door got jammed. Parts took less than a week to arrive and installation took approximately two hours because I took my time and familiarized myself with the unit which I just inherited with my "new" house.

The parts arrived quickly (4 days) and included everything I needed (gears and associated parts)to get my 26 year old Craftsman garage door opener running like new. Identical replacement parts of high quality. Good instructions too! Many thanks!

Order arrived very fast and the gear was mostly all we needed to replace (along with using some of the grease included and the pin that holds the gear in place).
Garage door opener works again! One suggestion would be to NOT just offer a roll pin to keep the gear in place but a plastic clip? Almost impossible to remove and insert unless you have a special tool. We had to use a hacksaw to get the gear off and then tap out the roll pin. That was the worst part of the job.

this kit has everything you need. I skeptical of the quality of parts at first but once I received the kit, the parts are OEM, not some cheap knock off.

This did the trick, and came with well-written instructions in English.

Great price. Fast shipping. Easy install. I only needed to replace the planetary gear, not the worm gear, so the install only took about 15 minutes..
