Spring Trolley Nut

$12.96

Fix Number: FIX10290179
Manufacturer Part Number: 41B4103

A loose garage door opener belt may slap, sag, or move poorly along the rail. The spring trolley nut works as a belt tensioner, helping hold the belt at the setting needed for normal trolley travel. It can replace an assembly that no longer tightens or has damaged threads or spring pieces. Before making adjustments, close the door, disconnect electrical power, and keep hands away from moving parts. Use the instructions for the opener when tightening the nut. Too much tension can place extra stress on the belt and rail system.

Manufacturer Part Number: 41A2817

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.
