Great Value
So the drive gear on my garage door opener became worn and the chain kept coming off. My first thought was to buy a new opener for about $200. Then I stumbled on the gear assembly for about $10 (I think it's about $15 now). It was relatively easy to replace the old one. Since the assembly doesn't come with any instructions, I highly recommend checking out a couple of YouTube videos which will make getting the chain repositioned correctly after the gear assembly is installed.

Works as advertised
No instructions provided as this gear/sprocket can be used for several different units but it was easy to figure out with all the YouTube videos out there. Very happy with the purchase as it allows me to forgo buying a $300 replacement opener.

A novice can do it!
My husband and I (not garage door savvy) were able to repair our garage door opener with this part and a little bit of Youtube know how. For about $14 and a couple of hours of labor, our garage door opens and closes again without a hitch. I would probably take less than 2 hours to do, but like I said, novices here. I can't image how much money we saved by doing it ourselves.

Poor fit, poor quality
Multiple issues with this kit.- The clip that holds the position sensor gear must be removed (and replaced) for installation. However, when I tried to remove the clip, it wouldn't budge. I finally ended up breaking the clip and using a drift pin to drive the remnants out of the hole in the drive shaft. The problem was that the hole in the shaft was too small (~ 0.020" as compared to the OEM part) and also had a burr on one end. I drilled out the hole to proper size, and used the clip from my existing opener.- The worm gear would not fit over the motor shaft. The inside diameter was 0.010 to 0.015" too small. The part is molded of a relatively soft plastic (nylon ?), and so I was not able to drill out to the right size (ever try to machine jello ??). The OEM worm gear is of a fairly hard plastic. Also, the quality of the part was abysmal. There was excessive flash from the mold separation line, and even a void on the ID where the mold did not completely fill. Fortunately, the worm gear on my existing opener was in good shape, so I could use that.- The main drive spur gear appeared to of "ok" quality, But when I tried to assemble the unit, the gear did not mesh well with the worm gear. It appears that the pitch diameter is larger than the OEM part (I have no way of measuring that). I was able to jam it together, but the gears are under a lot of pressure. Because of this, I expect the gears to fail soon, and perhaps also the bearings on both the motor and main drive shaft.On the positive side, the metal parts (sprocket, bearings, etc) all seemed to be good quality.

It worked.
The gears are a little oversized. I had to remove the large gear and replace it with the original, then it worked. The rest was well made.

Perfect fit, everything I needed for repair!
The media could not be loaded. Part fit perfectly and wasn't too hard to install, I opened up the end of my opener and was able to reach the 3 screws that hold it in out and lift the old part out and install new.Took me about an hour.Saved hundreds of dollars and my 20+yr old opener still works great again!Would recommend to anyone that likes to fix their own stuff.

Onderdeel past niet en is onvolledig
Onderdeel past niet en is onvolledig, schroefdraad ontbreekt... je moet al heel veel en specifiek materiaal in huis hebben om dit te doen werken.
