> 3 dayWorked perfectly for Craftsman opener where the sprocket and snapped off after nearly 15 years of wear/friction. I only used the main shaft/gear....I did not replace the worm gear as that required taking the motor out. The part slid right in and fit perfectly. Took me longer to take the screws out than it did to actually position the part. Great price for a good part. Comes with lots of grease and decent instructions.

> 3 dayInstructions were great. The only thing I would recommend is a if they included a small bearing puller to remove the motor bearing for replacing the screw drive.

> 3 dayJust what was needed to repair broken garage door opener. The gears had stripped out and these were the replacement pieces needed. Got this due to several reviews saying it was easier to get this kit with the gear already on the sprocket. Unfortunately, the sprocket was the wrong size and we had to remove the new gear from new sprocket and put it on the old sprocket. We could have a few $$ by ordering just the gear replacement kit. But no way to know that until you get into it. It worked and now the garage door opener is much more quiet than ever before. Much more economical than paying for a professional and/or replacing the opener. If anything would happen again, now we know to just get the gear kit.
