How to Replace Garage Door Spring and Cable

Replacing garage door springs and cables is a task that requires a good understanding of the mechanics involved and a commitment to safety. Garage door springs are under immense tension, and improper handling can lead to serious injury or even death. If you’re not comfortable with any of these steps, please contact MM Garage Door Repair Utah for professional assistance. We’re here to help!

Safety First

Before you even think about touching anything, let’s emphasize safety. Garage door springs store a tremendous amount of energy. A broken spring can whip around with incredible force. Here’s what you absolutely must do:

• Disconnect the Garage Door Opener: Unplug the opener from the electrical outlet. This prevents accidental activation while you’re working.
• Secure the Door: Use clamps or locking pliers on the track just above the rollers to prevent the door from moving. This is crucial!
• Wear Safety Gear: Eye protection and gloves are essential.
• Never Work Alone: Have someone assist you.

Tools You’ll Need

Gather all the necessary tools before you begin. This will help you work efficiently and safely.

• Winding Bars: These are specifically designed for winding and unwinding torsion springs. Using anything else is extremely dangerous.
• Wrenches: You’ll need wrenches to loosen and tighten bolts.
• Pliers: For manipulating cables and small parts.
• Screwdrivers: Both flathead and Phillips head.
• Safety Glasses: Protect your eyes from flying debris.
• Gloves: Protect your hands.
• Clamps or Locking Pliers: To secure the door.
• New Garage Door Springs: Make sure they are the correct size and type for your door.
• New Garage Door Cables: Ensure they are the correct length and thickness.

Step-by-Step Guide

Now, let’s get into the process. Remember to take your time and double-check each step.

1. Release the Tension on the Old Spring: This is the most dangerous part. Insert a winding bar into the bottom hole of the winding cone. Loosen the set screws. Slowly and carefully unwind the spring by moving the winding bar upwards, one quarter turn at a time. Insert the second winding bar into the next hole to hold the spring in place while you reposition the first bar. Repeat until all the tension is released.
2. Disconnect the Old Spring: Once the tension is completely released, you can disconnect the spring from the center bracket and the end bearing plate.
3. Remove the Old Cable: Loosen the cable from the drum. Then, detach it from the bottom bracket. Be careful, as the cable may still have some residual tension.
4. Install the New Cable: Attach the new cable to the bottom bracket. Make sure it’s properly seated in the groove.
5. Install the New Spring: Slide the new spring onto the torsion tube. Secure it to the center bracket and the end bearing plate.
6. Wind the New Spring: This is the reverse of unwinding. Insert a winding bar into the winding cone. Wind the spring the correct number of turns (usually indicated on a sticker on the door or spring). The number of turns depends on the height of your door (e.g., an 8-foot door typically requires 32 quarter turns). As you wind, insert the second winding bar to hold the spring in place.
7. Secure the Set Screws: Once the spring is fully wound, tighten the set screws on the winding cone.
8. Attach the Cable to the Drum: Carefully wind the cable around the drum, ensuring it’s properly seated in the grooves. Tighten the set screws on the drum to secure the cable.
9. Repeat on the Other Side: If you’re replacing both springs and cables (which is highly recommended), repeat the process on the other side of the door.
10. Test the Door: Remove the clamps or locking pliers from the track. Manually lift the door a few feet and let it go. It should stay in place. If it doesn’t, the springs may not be properly tensioned. Make small adjustments as needed.
11. Reconnect the Garage Door Opener: Plug the opener back into the electrical outlet. Test the door to ensure it opens and closes smoothly.

Tips for Success

• Buy the Right Springs: Garage door springs come in different sizes and strengths. Use the old spring to determine the correct replacement. Measure the wire diameter, inside diameter, and length of the spring.
• Replace Both Springs: Even if only one spring is broken, it’s best to replace both. The other spring is likely nearing the end of its lifespan.
• Lubricate the Moving Parts: After replacing the springs and cables, lubricate the rollers, hinges, and tracks with a garage door lubricant.

FAQs

Q: How do I know what size springs to buy?

A: The best way is to measure the old spring’s wire diameter, inside diameter, and length. You can also look for a color code on the spring, which indicates its strength.

Q: What happens if I wind the spring too much or not enough?

A: If you wind the spring too much, the door will be difficult to close. If you don’t wind it enough, the door will be difficult to open and may not stay in place. Adjust the tension as needed.

Q: Can I use a pipe wrench instead of winding bars?

A: No! Winding bars are specifically designed for this purpose. Using a pipe wrench is extremely dangerous and can damage the spring.
