This was one of the easiest repairs I have done around the home. The instructions were obviously written by someone that had done the repair. And the opener works perfectly now. I have since ordered another for the same thing except his damage will include the kit that has the new bearing.

I purchased this to replace one that had snapped in half on my Liftmaster opener. It arrived very quickly, and included clear instructions, the part, and grease. Removing the pin to get the sprocket on was the most difficult part. If you don't want to fight with removing the pin, you can buy the gear and sprocket kit, and the gear will already be mounted on the sprocket. All you have to do is remove the old one, and drop the new one in,

I replaced the failed gear on my LiftMaster garage door opener. At first, it didn't appear following the instructions was going to provide access to the gear...but I followed them precisely, anyway, and the gear fell off the shaft, and into my hand. Sure beat paying a 'professsional' $100 - $200 to do the same thing...

Unable to get the lower retaining pins out, so I removed the chain and pulled out the top drive unit and placed it into my large vise. After chipping away part of the old plastic gear, the pins released. With the upright unit out it was easy to insert new drive gear and pins. Reinserted unit onto worm drive and reconnected the drive chain. Lubed in place and reconnected the worm stop system..minor adjustments to up & down. Works like a charm...quite a saving for a retired guy!

I installed 3 in the last month and they all fit perfectly. One was in my house I am getting ready to sell and two in another house we just bought. By the third time,I learned the shortcuts and it was an easy install. I suspect most people would have bought a whole new garage door opener, but this worked perfect.

Item exactly as described. Included excellent instructions and needed grease. Shipping was very quick after order was placed. Repair was successful and my door is working like new again. Item was the large drive gear.

Do this
Don't hesitate, just do this...much cheaper (and far easier) than replacing the whole opener. Fast shipping, and great "shortcut" instructions that make installing this real easy. One note: put a rag behind the pin when driving it out, it will fly out of there and across the garage and you'll be off to the store for a new one if you can't find it. Thanks!!
