The steps in how to repair a garage door are the following:

  3. Secure torsion tube and remove old springs
  4. Install new center bearing and left spring
  5. Replace rollers, lift cables, and bottom brackets

We’ll go over each of these.

Step #1: Lock the Garage Door & Loosen the Unbroken Springs

You’ll first start by clamping the garage door using the locking pliers and clamps. This is to help prevent any accident that might occur due to an unlocked garage door.

Then, using your winding bar, you’ll loosen the good spring. Place it into the winding cone and start loosening the setscrews. Be careful, since the spring can rotate aggressively when loosening it. 

Step #2: Unwind and Disconnect the Springs from Center Bracket

Using a second winding bar, place it into the next hole, making almost a 90-degree angle between the winding bars. After that, remove the first winding bar and turn the spring. Do this in passing over motion. 

Remove the bolts and nuts that are in the stationary cones. After that, try to slide the springs to the brackets that are in the end.  

Step #3: Secure Torsion Tube and Remove Old Springs

Use your locking pliers to loosen the setscrews that are on the right and left light cable drums. Then, disconnect the cables. 

When you finish disconnecting the cables, start on the left side of the door by sliding the torsion tube to the right. That way, you can remove the cable drum. Lastly, you can push the broken spring off the tube.

Step #4: Install New Center Bearing and Left Spring

First, you’ll need to reassemble by sliding the replacement of the torsion spring onto the tube. Keep in mind that during this step, you’ll need to have the stationary cone facing the center bracket. After that, you’ll be able to install the cable drum again and reinsert the torsion bar.

Second, you’ll need to connect the stationary cones onto the bracket by sliding the center bearing onto the torsion bar.

Step #5: Replace Rollers, Lift Cables, and Bottom Brackets

This is the perfect time to change any rusted rollers, cables, and bottom brackets. You can do this by first placing the lift cable loop onto the new bottom bracket. 

Step #6: Thread Cables and Tighten Drums

You’ll need to secure the lift cable onto the cable slot. Also, remember to tighten the drums by using the pliers. After that, it’s time to wind the wire, tightening as much as possible before placing the setscrews. 

Finally, you’ll want to make sure that both sides of the garage door are tightened equally. That way, your door will open adequately and evenly.
