The motor of a chain-drive garage door opener has a sprocket attached to the top. The sprocket’s teeth may wear over time and the opener might raise the door without the chain moving. The motor’s lifespan can be extended by replacing the sprocket as soon as it starts to wear. An opener brand and model can be used to identify a DIY homeowner who is skilled in mechanical repairs.

Here is a step-by-step guide from Garage Door Repair Sachse TX to follow on repairing your garage door chain.

1. Pull down the trolley cable and lower the door to free the trolley arm. Install a stepladder beside the motor. Then disconnect the power cord to the ceiling’s electric outlet. The snap-on cover that wraps around a motor’s shaft can be removed with a screwdriver.

2. You should move the ladder towards the garage door’s end. By loosening your chain arm’s bolts, slide the pulley one inch toward the motor.

5. Once the pulley is tightened, move it towards the garage door. Next, move the pulley towards your motor until it touches the upper end. Now tighten the bolts.

6. Attach the cover over the sprocket. Next, plug in the power cord for the motor to an outlet. To reinstall the trolley at its chain arm position, move to the flooring below.
