This video from Sears PartsDirect shows how to replace the gear and sprocket assembly on a chain-drive garage door opener. The gear and sprocket assembly drives the chain that moves the trolley along the rail to raise and lower the garage door. A broken gear and sprocket assembly won’t move the chain to raise and lower the door when the drive motor runs. Replace the gear and sprocket assembly if it’s broken.
