2 Pack - Drive Gear for Sears Crafsman Liftmaster Chamberlain Garage Door Openers 1984-Current

The media could not be loaded. Easy to install, opener works like new, make sure you grease the gears when you put them in. Fixed the garage door for $7 and have a spare gear. A garage door company would have charged $250 for this simple repair or tried to sell you a new opener.

Pretty easy to install. Just follow instructions on countless youtube videos out there.

Can’t beat the price and free next day shipping is perfect! 15min repair and works perfect.

I followed the directions on a YouTube video. It took me a couple of hours to change the gears out. The directions were spot on. It just happen to be a very cold day, so I needed to wear gloves through most of the steps. The garage door has been running well this past month. It runs much quieter since greasing the gears. I would highly recommend these gears. Much cheaper than replacing the whole garage door opener.

Recently my garage door stopped working and made a loud popping noise. Well thanks to the internet I looked it up and found the common problems with my model is the plastic gears break over time, When I pulled the cover sure enough the gear was in pieces.After doing a little looking around on the internet for new gears by the maker of my opener, I was completely floored by the price they are trying to charge for one gear and nothing else. Now don't think right off that I am a cheapskate or anything but to pay almost $30.00 for one little plastic gear is pure crazy in my book, I would rather spend that money buying a new one that has all new parts and possibly a better design.Well the frugal side of me decided to take a quick look on Amazon for them and I am glad I did. I can get two gears that are the same exact quality and materials as the factory one for less than a third of the cost of what the maker was charging for one. I am always skeptical about buying the cheap part to complete a repair on something that could fall down and hurt someone or damage something. After the parts arrived I compared them to the factory one and it was the same exact materials, same size, shape and everything was identical. The parts have been in use for several months now and are no worse for wear that I can see, the gear shows absolutely no wear at all.At this point I say it is definitely a great way to replace the factory gear with an identical part for tins of money less than they try to charge you at the big box store it came from, and I have a second one in hand in case this one ever fails. Highly recommend it to anyone that needs this gear and doesn't want to pay the overpriced rate they try to shove down our throats these days.

Perfect fit. Easily installed.

These gears are 100% identical to the original in my garage door opener. I did not rate the ease of installation because it's a full afternoon's job, but that's because you have to dismantle most of the opener to get to the gear, and that's not the fault of the replacement gear. They came with a page of instructions which were actually pretty decent, so that's a plus. I have a 3/4 HP opener on a double-wide garage door; the original gear broke after 11 1/2 years, so not bad. They are made of nylon (original and replacement) and I was skeptical that it would tolerate the stress, but it's been in there for about five weeks and is still working. If it lasts 11 more years I'll be happy!

Garage door opener stopped working and upon investigation I found that I could buy this gear and repair it. The process took about 1.5 hours to disassemble and reassemble and wasn't hard, just tedious. The hardest part was knocking out a pin that holds this gear to the shaft (I used a nail that fit perfectly).The reason for the low review is because after install I found another gear that was already mounted to the shaft and also included the grea on top that the chain runs on. It wasn't a lot more expensive and would be much much quicker to install. So no offense to this product, it worked perfectly, but there is a quicker and easier solution out there.P.S. make sure to also buy some lithium grease with this to lube the gears and the track. Lithium is better on plastic pars for the gears and wont dry out on the track like typical grease.
