I asked the local garage door repair company how much they'd charge to replace the gears. I followed the instructions exactly, removing the cover, then the motor assembly and then the sprocket and gear set."
"I already had the old part removed and it took about an hour to install the new one and get the chain reconnected."
"You will likely have to adjust your travel limit settings since removing the shaft can rotate the travel switches gear a tooth or two or more if you spin the gear."
"This job is extremely easy to do just make sure you don't do what I did and get confused with putting the chain back on I had the opener in the up position but the chain on in the down position."
"Definitely check out some of the videos on YouTube but here are a few tips that I used that will make it easier than doing it exactly like some of the videos that are out there: -- UNPLUG the opener before you work on it. 2) I unplugged the internal wire connector from the back plate to make it easier to move around and I just set it on top of the opener while I worked. Use your driver to run the screws partway into and out of all 3 holes BEFORE you put the shaft into the opener and they will then be threaded."
"If will take a lot longer if you start replacing the bearings, bushings, and worm gear."
"It took quite a bit of time and having 2 sets of hands and a very good youtube video made it a heck of a lot easier. I have read some reviews stating that because it was so hard and took so long they removed 1 or more stars, but I cannot remove stars for that because the kit manufacturers have no control over how easy or not it is to repair your opener."

"Another for instance, I have a big door, and I had to use vice grips (lever locking pliers) to hold the chain against the I-beam (track) to remove slack before I could even get the chain off what was left of the stripped sprocket that I had to replace, as well as to get it back on the new sprocket when done. Use good spray can of white grease (Auto Zone) to lube the entire chain when done."
"The chain sprocket broke off my garage door opener and I was thrilled to find out that it could be replaced without having to pay a professional or buy a new opener."
"As others have suggested, you'll want to tap the holes on the top by forcing the screws into the holes (the screws do the tapping), while holding the assembly in a vice or in your hand rather than while trying to install it. Of course, I didn't, so I had to drop the whole thing down onto a cardboard box I placed on the top of a step ladder. At the end, you need to adjust your door travel limits via the two screws on the side."
"Adequate and complete instructions included - only real challenge was that I had to lightly sand away scars on the motor shaft that retention screws had made before being able to remove bronze bushing on screw gear (yes there were obscenities involved because I broke the lip off the bushing by trying to force it over the scars ,,, a minute with 400 grit sandpaper and the problem was solved and the cursing stopped). other issue was that my old lift "resets" to the opposite state (open vs. closed) as in the instructions... but this was easily remedied by adjusting the limit screw to the opposite end."
"I had to pound out the pins holding the gear and ended up replacing only the gear on the old shaft assembly."

PROS: Inexpensive way to extend the life of your garage door opener. Simple enough instructions. CONS: Using the kit may delay replacing the garage door opener for safety reasons. Time consuming to replace parts."

"I don't recall whether the keys were made of copper or zinc plated or how the keys were designed/cut. It's a key like any other key."
"First thing I did upon entering the house after that was to put the key for this release on my car keyring."
"For most garage doors if you install it at the top of the door it will dangle down really low when you have the door open and can catch you in the head. I recommend mounting it lower down on the door to account for the length."
"Since buying my house a year ago I've been wondering what to do if we lose power or the garage door opener motor breaks."
"i am not very happy about this because now i have to buy a cable tie to attach to the old left over cable."
"36" of cable is at least 12" too short to get enough angle to pull the release since the J-bar is mounted the opposite of the way it is mounted for a sectional door."

"Works great on my 15 year old Sears 3/4 HP opener."
"I used them to replace some old ones that were malfunctioning and every time it was sunny my garage door wouldn't shut."
"If you do not get the wire end in completely it can slide off or not provide a complete connection."
"Very easy to install, two wires, uses the same brackets and light tells you if they are placed correctly."
"I replaced the sensors on my Liftmaster (made 2005) with these, works right out of the box and gets the job done."
"Solved the problem of my garage door not closing all the way."

"I will say that I added lift motor bushings at the same time (link below) so I cannot say these 100% improved the noise reduction."
"After installing these rollers the door was a bit quieter but not significantly. After eliminating the rollers as the source of the noise problem I figured maybe it was the springs rubbing on the tracks."
"After watching a score of garage door repair videos online, nylon rollers seemed to be universally recommended."
"For that one, moving the track and pulling the door down until the wheel clears the upper track may be a better option."
"Once installed all I can here when the door opens or closes is the low hum of the garage door opener."
"I removed the top 4 hinges on each side to replace one at a time. Hurricane garage doors in Fla. thanks are very stout, couldn't use quick method on YouTube, I was not able to replace the bottom roller on either side, yet."
"My rather old garage door operates more smoothly and more quietly."

Considered this to be a fairly simple task and the satisfaction of doing it yourself and having your garage door working properly again is a fantastic feeling."
"Easy to replace, just buy it, get a ladder and remove a few screws and wire connectors and the door functioned fine again."
"My Liftmaster stopped working, no lights, etc."
"This replaces a lot of legacy logic boards (mine was 41A5021-C). It's really easy to install."
"Replaced a malfunctioning 41A5021-4E with this, switched out the logic board since the mount on this wasn't the same; was simple enough, didn't take long, and my remote works again... but I may not even use it anymore since this was able to learn my car's internal remote feature."
"Replacement went as smooth as silk and the part fit perfectly!"
"After various efforts to figure out what was going on with my garage door opener, it finally resolved to needing to replace the logic board."
"MY GARAGE DOOR IC BOARD WIRELESS CONNECTION FAILED, STILL COULD USE IT FOR OPENING AND CLOSING THE DOOR FROM WALL SWITCH."
