## Customer Reviews

### ⭐⭐⭐⭐⭐ A couple of hours and my opener is like new!
*by J***F on May 29, 2025*

This is a high quality kit that most DIY'ers should be able to use to refresh their garage opener. I only used the work drive assembly from the kit and had excellent results. I found the repair to be tedious but will worth the time invested. My garage door operated so much more smoothly and quieter than before. I believe replacing all the parts would have been even better, but believe this repair should outlive the 25 year old opener.

### ⭐⭐⭐⭐⭐ Garage door working again.
*by A***R on May 16, 2025*

Clear instructions. Parts fit perfectly into my opener.

### ⭐⭐⭐⭐⭐ Great stuff!  Watch the YouTube videos!!
*by C***N on March 20, 2021*

The parts were great, but I only used the sprocket + big gear + small gear - the "big ass" piece. I didn't need the worm gear and the other parts in the bag.When my garage door refused to close I figured the big nylon gear had stripped. Drat. Garage door guy asked me a coupla years ago if I wanted him to replace that, and I asked what he'd do. Replace it when it dies. I took his advice. I didn't count on him retiring and the other garage door crew here in Havasu cheerfully bend ya over to do anything.As soon as I pulled the cover (eight 1/4" screws - four coarse thread into plastic, four fine thread into metal) and saw the big gear stripped ordered this kit, which arrived as soon as US Postal found where they lost it - just a day delay. I wish 'Zon wouldn't send stuff US Snail.Anyhow, I watched a great vid on YouTube where a handy guy replaced only the gear - more work, but the gear is six bucks vs. kit is $20. I watched another YT vid by a guy who works on garage doors for a living. Both had great info!Our son did the work, I provided arm-waving. Easy to remove the chain, afix to track, remove two screws from underneath with 5/16" nut-driver, say bad words and remove third screw with 5/16" end wrench. Remove an E-clip and the tiny gear which controls door travel, smack the end of the shaft with calibrated mallet and out comes the old sprocket and gear assembly.After kit arrived, I locked the trolley to the door, and closed the door. We lubed all of the gears with grease supplied. Lubed bearings and bushings. THREADED holes in new cover with 5/16" screws we removed. DO THIS BEFORE installing! Put two of those screws in. Say bad words, and install the third with a wrench. Install lower gear and E clip. Plug it in - no smoke! Whew. Re-attached the chain and locked in place.Tested door twice - ok but goes up too far and not far enough down. Install cover, adjust travel screws a half dozen times while raising and lowering door until perfect. Well, good enough.Watch the vids. The one done by the garage door guy is 45 minutes long, but he'll save you lots of cursing and maybe some breakage. The one done by the handy-guy saved me lots of time. To do this you don't need to remove the whole mechanism or the motor from the mech - as long as your big worm gear is not destroyed.This was pretty easy - about an hour and a half total. Plus an hour to watch the videos. It was easy for me cuz our son did the work. Note that I have most of the tools known to God and man, so we mostly used the right tools, as fast as I could find the darn things<grin>. If you are not handy, don't have a good collection of tools or aren't safe on a ladder, don't tackle it yourself. I had to open the door, move the car, then close the door myself five days, which reminded me of when I was a kid. Glad I now have a robot to do that for me.
