How to Install a New Spring on a Manual Garage Door

Replacing a garage door spring can seem daunting, but with the right tools, knowledge, and a focus on safety, it’s a manageable task. Before we dive in, let’s emphasize that garage door springs are under immense tension and can cause serious injury or even death if mishandled. Proceed with extreme caution.

Safety First

Before you even think about touching anything, disconnect the garage door opener. Unplug it from the outlet to ensure it cannot be accidentally activated. Next, clamp the garage door to the tracks using C-clamps or locking pliers. This will prevent the door from suddenly dropping when you release the tension on the spring. Wear safety glasses and gloves throughout the entire process.

Tools You’ll Need

Gathering the right tools is crucial for a successful and safe spring replacement. Here’s what you’ll need:

• New garage door spring (correct size and type)
• Winding bars (correct size for your spring)
• C-clamps or locking pliers
• Adjustable wrench
• Socket set
• Screwdrivers (both flathead and Phillips head)
• Safety glasses
• Gloves
• Ladder

Step-by-Step Installation Guide

Now, let’s get to the actual spring replacement. Follow these steps carefully:

Step 1: Secure the Door

As mentioned earlier, ensure the garage door is clamped securely to the tracks. Place the clamps just above the rollers on both sides of the door.

Step 2: Loosen the Existing Spring

This is the most dangerous part of the process. Insert one winding bar into the winding cone of the spring. Hold it firmly. Loosen the set screws on the winding cone using an adjustable wrench. With the winding bar securely in place, slowly and carefully loosen the spring by inserting the second winding bar and alternating between the two, releasing a quarter turn at a time. Maintain a firm grip on the winding bar at all times. The goal is to release all the tension from the spring in a controlled manner.

Step 3: Remove the Old Spring

Once all the tension is released, carefully remove the winding bars. Disconnect the spring from the center bracket and the end bearing plate. Slide the old spring off the torsion tube.

Step 4: Install the New Spring

Slide the new spring onto the torsion tube. Ensure it’s oriented correctly (check the winding direction – right-wound or left-wound). Attach the spring to the center bracket and the end bearing plate.

Step 5: Wind the New Spring

Insert one winding bar into the winding cone. Hold it firmly. Insert the second winding bar into the adjacent hole. Using the winding bars, wind the spring the correct number of turns. The number of turns depends on the height of your garage door (typically, it’s the door height plus 0.75 turns). Consult your spring manufacturer’s instructions for the exact number of turns. As you wind, maintain a firm grip on the winding bars.

Step 6: Secure the Spring

Once the spring is fully wound, tighten the set screws on the winding cone securely. Remove the winding bars carefully.

Step 7: Test the Door

Remove the C-clamps from the garage door tracks. Carefully lift the door manually to test its balance. If the door is difficult to lift or falls quickly, you may need to adjust the spring tension slightly. If so, repeat steps 5 and 6, making small adjustments until the door is properly balanced.

Step 8: Reconnect the Opener

Plug the garage door opener back into the outlet.

Tips for Success

• Double-Check Everything: Before releasing the door, ensure all connections are secure and the spring is properly wound.
• Lubricate: Apply a garage door lubricant to the spring and rollers to ensure smooth operation.
• Proper Spring Selection: Using the correct spring size and type is crucial for safety and performance. If you’re unsure, consult a professional.

FAQs

Q: How do I know what size spring I need?

A: The best way is to measure the old spring’s wire diameter, inside diameter, and length. You can also weigh the garage door to determine the appropriate spring size.

Q: Can I replace just one spring?

A: While technically possible, it’s highly recommended to replace both springs at the same time. Springs wear out at similar rates, and replacing only one can lead to imbalance and premature failure of the other spring.

Q: What if I’m not comfortable doing this myself?

A: That’s perfectly understandable! Garage door spring replacement can be dangerous. Call MM Garage Door Repair Utah at 801-418-9217, and we’ll be happy to send a qualified technician to your home.
