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

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

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.

Perfect fit identical to the OEMVery easy to replace. You will have to add your own lithium Grease to the gear wheel. It is very important to have the grease on the drive gear wheel.

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.

Everything I ever got has been good

Come with 2 nice gears. I need only one. Save the other for other lifts or for the next 20 years.The gear is softer nylon than the worm gear. After 20 years the worm gear is still good. The drive gear teeth finally wore thin and lost traction. White nylon powder off from the drive gear piles in the casing next to the worm gear. The motor only turns and the worm gear rubs the drive gear which does not turn any more. Although the manufacturer's manual says to replace both gears and accessories, no other part has significant visible wear. I only replaced the drive gear. Completed the 4 steps of adjustments and testing, and the lift was back to normal.Other reviewers wrote good step-by-step instructions. I will add that the two pins that are holding the drive gear are made of spring steel. Only need to drive the bottom pin out and in. Hammering it out or in with a drive will not damage it.I did put some lithium grease on the teeth. I don't think the teeth had been regreased in the last 20 years after the original installation. I did not see any trace of grease when I took the opener apart. I would not think regreasing would make much difference, but I will probably regrease the gears every year or two.

item seemed to fit well, but when operated, worm gear is slightly off and ends up shaving the gears to the point where they eventually strip out. This was only after 3 openings/closings.

As advertised

Concernant ma dernières commandes(lot de 2engrenages ) celles -ci après avoir été changée ont fonctionné 4allez retour ceci signifie quelles sont de très mauvaises qualités les dentelures n'ont pas tenues le coupusure quasiment immédiat, vraiment déçu de ma commande .Dommage.

Nothing to dislike, install the new gear. Garage door works great and l have an extra gear if l ever need one.

Product fits as advertised

Was used to replace gear in garage door owner that had frayed. Fairly easy to install and definitely value for money.
