This is a high quality product that matches up with specific Chamberlain, or Liftmaster models numbers that are available, on their website.

Great for my 1995 Chamberlain. Works great now! Highly recommend watching youtube videos to do this as included instructions are on a small piece of paper, printed at a fairly low resolution. This is a very doable project for the average DIYer. It's not easy, but it can be done. Here are a couple tips and a couple places I was hung up: --Take pics of wiring configurations --Don't mess with the travel/force settings and don't unwire the back where all the controller inputs connect if you don't have to. --You'll need a punch that's the exact width of the roll-pin that holds the white gear on the shaft. If it's not the same width, it'll widen the pin, which is counterproductive. They are a pain to get out. Strike hard and true and a lot. --Once you drop the motor assembly, you'll need to use a flat screwdriver and a hammer to get all the pieces off the shaft. There's one collar that really stuck for me and was the last piece preventing me from accessing the worm gear. --Related to the last part, get everything as far onto the shaft as you can once you put it all back together. I failed to do so on the first try and had to pull the motor back out to fix it. The problem that arises is that the shaft moves in and out and the slop makes it impossible for the RPM sensor to work right. This caused my door to open and close about 5' before reversing direction. Pulled it out, helped the parts down the motor shaft with a hammer, put it all back together and worked great. --The last fun part is putting the chain back on so that it's aligned properly upon open/close. During this phase of moving it and testing it, do NOT allow the door to hit the metal stops in the track when testing it out. All your tension will go to one side and the opener can't move it. If this happens, be aware that the tension releases with the fury of hell. i.e., stand on the opposite side so when it lets go it doesn't gash your face...or maybe have a pro handle it. I released it from the drive sprocket with a wrench and it made quite the noise. --If you pull this off, you'll become a garage door opener pro and get a really good understanding of how it works, which I have to say is really cool and why I do these projects myself. It'll take a good amount of time if you don't know what you're doing, so maybe clear your schedule for an afternoon. Good luck
