"When my garage door opener's drive gear became worn, I considered buying a new unit for around $200. Instead, I found a gear assembly for about $10. It was fairly easy to replace, but I recommend checking out YouTube videos for guidance on repositioning the chain correctly afterward."

"While the product arrived quickly and replaced my 24-year-old opener well, I was disappointed that there were no instructions or warnings included. I managed to find instructions online, and I’m glad I did because it saved me from buying a new opener."

"I installed this kit yesterday and found the installation process quite straightforward. Working on a bench instead of overhead was a significant advantage. I only needed to glance at the instructions once, as disassembly and reassembly were simple. I have some tips: sanding the motor shaft where the collar secures the worm gear made replacing parts much easier. After finishing, I made minor adjustments to the limiters, and now it works perfectly. Great parts and seller! Thanks!"

"After my garage door derailed and broke the gear, I was looking at a repair bill over $300. Fortunately, my partner stepped in to help. I found a great deal on Amazon, and it arrived quickly. My partner fixed the door, and it has been working flawlessly for about three months now. I’m thrilled with the price and performance of the part!"

"I found this unit to be of OEM quality. Replacing the part took some effort, but for anyone mechanically inclined, it’s manageable. Way better than replacing the entire opener, and it has been working well for several years."

"I received the order last week, which came with both the drive gear and worm gear as well as bushings and grease. My garage door opener is old; it is a Liftmaster 2255. The main issue was with the drive gear, but having also the worm gear, I decided to replace it, too. The original bushings in the motor shaft did not come off easily, and I had to use pliers and a hammer. I broke the bearing trying to insert it, as it was difficult to put on the motor shaft. Fortunately, after contacting the seller, I received a second set and successfully installed the parts. The parts fit perfectly, but I must mention that the installation was time-consuming and challenging. I now know a lot about garage door openers!"

"We couldn't find this part in any store, as they all wanted us to replace the entire system. This part was easy to install and worked perfectly on our garage door. We are ordering extras to avoid future issues with finding this part again."

"This product offers great value for money considering its features."

"I found the part to be a perfect fit for my 2017 Chamberlain garage opener with a yellow button. I accidentally adjusted the traverse limit, but thanks to some YouTube videos, I managed to fix it. Just a tip: your specific motor might have a unique drive setup, so not all components may be necessary from the package. Having a helper made the process easier for me."

"I successfully repaired my old Craftsman garage door opener using this part. The instructions were clear and easy to follow, and it even came with an online video. I'm hopeful about its durability, but I did notice that Amazon's packing for shipping wasn’t great, leading to some minor damage during transit. Despite that, I was able to use the part without issues."

"This part fit perfectly in my 1993 Liftmaster 1245. I did encounter a bit of a challenge with a hard-to-reach screw on the top cover. I managed to install the two easier screws from the inside and after some time, I got the difficult screw on from the outside. I used a small nut and a lock washer to secure it, and thankfully, it didn't interfere with any internal components."

"My garage door opener, a Chamberlain 41A5021 from the early 2000s, broke down. After inspecting it, I discovered the chain gear had sheared off the main drive shaft. I found this repair kit online, and after some hunting, I realized many Chamberlain and Liftmaster units share similar construction, so this kit would likely work for me. Though it didn't come with instructions, the YouTube videos were incredibly helpful. I completed the repair in about 45 minutes, and now my opener works like new. I saved around $130 by fixing it myself for just $20!"

"The Garage Outlet Gear and Sprocket Kit was the perfect fit for my ancient garage lift motor. Installation was a breeze; I just took the old part out and put in the new one.

Overall, this product saved me hundreds of dollars compared to buying a new opener!"

"This kit did exactly what it was meant to do, and I had no quality issues. While it lacked instructions, I found it manageable to research the replacement process on my own. If you have a mechanical mindset, you'll figure it out easily!"
