This is a drive gear kit for various garage door openers, providing all the necessary parts to replace a malfunctioning gearbox that may cause difficulty in opening your garage door. If you notice popping or unusual noises, or if the chain slips and is no longer catching, it is a clear indication that the gears need inspection and potential replacement. The kit includes essential components like a helical gear, a worm gear, grease, bushings, and various hardware such as washers and retaining rings to replace your current gears. If shavings are evident on the gears within the garage door opener, it is a sign that your chain is too tight. Replacing the drive gear set for your garage door opener is something you can do and only requires a socket wrench and screwdriver. Remove the outer panels of the garage door opener and loosen the chain to remove it. Inspect the garage door opener for which parts need replacing, and simply swap them out, and apply grease to each part before installing them. Reconnect the chain and the outer panels of the garage door opener and test it to make sure it works properly.

Installation Instructions

Dustin from Bismarck, ND

Tried opening my garage door when it was frozen to the ground resulting in a busted chain guide and pulley.

Step 1. I disconnected the power supply so no further damage could occur. Step 2. I got my osha approved step chair to diagnose the damage. Visually saw the broken pulley on the wall bracket, and broken chain spreader on the garage opener. Recorded model and serial numbers along with photographs of broken parts. Step 3 Looked online for the model number which lead me to parts at fix.com. There were other sites, but fix was simple enough and had enough information to confirm they did indeed stock the right parts I needed. Step 4 Wait a few days for delivery, the parts arrived in a plastic bag containing a box protecting the parts in shipping. Step 5 When 14 yr old son comes home I tell him what needs to be done and he does it without my help to much of my surprise. It must have been an easy fix. He even reprogrammed the travel route and got it working good as new.

Thank you fix.com for your easy to navigate website simplifying the parts finding process. Read more...
