1. Identify and Measure Your Old Springs
When preparing to replace your garage door springs, it’s essential to first identify whether you’re working with torsion springs or extension springs. For torsion springs, measure the spring’s length, its inside diameter (usually 1 3/4 or 2 inches), and the wire gauge by dividing the length of 20 coils by twenty.
Color coding can also guide you; torsion springs may have unique markings, while extension springs use a color pattern to indicate weight capacity. Always disconnect the garage door opener and wear protective gear to ensure safety.
Tips:
- Consult with the spring manufacturer or garage door manufacturer for the exact replacement product and installation guidance
- Companies design torsion springs and extension springs for specific weights and sizes of doors. Using the correct spring ensures balanced and safe operation.
- Remember, precision in measurement and identification is key to selecting the right spring and ensuring a smooth installation process
2. Prepare Your Tools and Materials, including Safety Gear
Before tackling the task of how to install garage door spring, ensure you have all the necessary tools and safety gear at hand. Essential items include a pair of 10″ vise grips, an adjustable wrench, and two 1/2″ X 18″ winding bars—vital for safely handling the torsion springs.
Most hardware stores offer 1/2″ X 36″ steel rods, perfect for cutting in half to use as winding bars. Additionally, equip yourself with C-clamps, a stepladder, work gloves, a ruler, and a file for precise adjustments. A socket wrench set can significantly speed up the process.
Proper lighting in your garage is crucial to ensure a safe working environment.
3. Begin Disconnecting Old Springs and Garage Door Opener
Start by securing the door to prevent it from moving. Attach a locking pliers or a C-clamp above one of the rollers on the track. This step prevents the door from unexpectedly opening and causing injury. Ensure the garage door opener is not connected for safety.
For torsion springs, use a winding bar for safe loosening. Insert the bar into the winding cone of the intact spring, and carefully loosen the set screws. Brace yourself for the spring’s force as you do this. If working with extension springs, open the garage door fully to relieve tension.
Prop the door securely, and mark the pulley’s position for accurate reinstallation. Detach the spring from the track bracket and spring pulley, handling the safety cable with care.
To remove the torsion springs, stabilize the torsion tube with locking pliers on the center bracket. Loosen the set screws on the lift cable drums to disconnect the cables.
4. Install the New Cable and Springs
Installing the new garage door springs begins with threading the safety cable through the spring, and securely attaching it to the track bracket. Identifying the wind direction of each spring is crucial. This ensures that doors with two springs have both a left- and a right-hand spring for balanced operation.
Next, slide the replacement torsion spring onto the torsion shaft, making sure the stationary cone faces the center bracket. Reattach the cable drum, carefully aligning the garage door wire.
Reinsert the torsion shaft into the bearing bracket on the left side, preparing for the final steps of installation.
Adherence to these guidelines is essential to ensure that everything from the winding cone to the torsion springs is correctly positioned and secured.
5. Reconnect the Safety Cable and Pulley
Once the new garage door springs are in place, it’s time to reattach the safety cable and pulley, a key step in how to install garage door springs and cables. Ensure the wire from the pulley does not interfere with the safety cable, maintaining clear separation for smooth operation.
Refer back to the tape marking you made earlier to confirm the pulley is at the correct location. This careful attention to detail is crucial to ensure that everything from the garage door opener to the torsion springs works in harmony.
6. Test the Door
After installing the new garage door springs, it’s crucial to ensure everything operates smoothly. Stand back and use the garage door opener to test the door. Watch as it lifts and lowers, making any necessary adjustments until the movement is smooth and balanced.
Next, apply a quality garage door spray lubricant to the springs. This not only ensures their longevity but also contributes to a quieter, smoother operation. Pay special attention to the winding cone and torsion shaft.
