I bought the entire repair kit but in my case all I needed was the one big gear and a new split pin. The old split pin was a real pain to get out - it had rusted in a bit (after about 30 years, so not too unexpected).
I would highly recommend getting the entire kit rather than just the one part as you don't know what problems you will encounter when you get it all taken apart.
Great value for money, delivered quickly, works perfectly.
Highly recommended if your door fails to operate and it is the gear wheel that has stripped... As other reviewers have stated - way cheaper than a new garage door opener and not that hard to replace.

Kit arrived in quick time with free shipping and was just as advertised. Relatively easy install. Warning, when tightening the three screws that hold the bearing plate be careful to avoid shorting one of the wires which is very close by.

I only needed the drive gear and grease, but ordered this kit just in case other parts were worn as well. Lowest price I've found when shopping around, and the company had it processed and shipped to my door within the week! Garage door opener works as good as new for a fraction of the cost for professional repair or replacement.

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!
