Safety Comes First

It is essential to plan ahead for a garage door spring replacement project. This removes some of the danger involved from the intense tension that the springs are under. Use only new winder cones; wear safety glasses; and always assume the springs are going to snap. Also, ensure that the power is disconnected prior to beginning any work.

Tools on Hand

Be sure to gather the required tools beforehand.

  • Two ½” x 18” winding bars (Or one which is ½” x 36”)
  • A pair of 10” Vise Grips
  • Adjustable Wrench
  • Cleaning Cloth
  • Sturdy Ladder
  • Socket Wrench with Socket Set
  • Ruler
  • File
  • Proper Lighting
  • File Pen
  • Torsion Springs

Proper Size

Lay the old garage door springs on the floor of the garage. Measure the number of coils, the length, and the inside diameter. This provides the correct wire sizes to ensure the proper fit and the safety of all.

Mark for Precision

User a file pen to mark the cable drums and shaft. The cables are also dangerous components of your garage door system. Unwind the springs to ensure they do not snap causing serious injury to your person or property. Be careful not to touch the drums while the springs are wrapped around them.

Unwind Springs

Be sure that you insert the correct bar inside the winding cone before touching the set screw. Ensure that the bar remains inside the cones the entire time.

Loosen Hardware

The next step is to loosen all the torsion hardware. Secure the slotted spring brackets with the vise grips. Once this is done, slide the springs toward the cable drums to a point out and above the top of your garage door. Next, loosen set screws and slide the drum away. If the ridges are worn, file the shaft.

Spring Replacement

  • Slide the rum away from the bearing.
  • File the end of the shaft, if necessary.
  • Properly lube the bearing.
  • Pull the shaft from the head plate.
  • Slide the old spring off.
  • Place the new spring in.
  • Slide it toward the spring anchor.
  • Reinstall the cable drum.
  • Straighten the bearing plate.
  • Ensure that you have put everything back in its place.

Install Torsion Hardware

  • Slide the drum to the shaft and tighten set screws.
  • Slide the end of the shaft to the end of the bearing plate.
  • Rotate the shaft to tighten the cable onto the drum.
  • Move to the other side of the door and insert the end of the cable in the drum.
  • Secure the torsion springs in the center.

Wind the Springs

Mark the shaft right over the winding cone to begin. Place the winding bar inside the cone. Work in a cycle. Raise the bar; turn; insert the next bar; and remove the first. Correctly winding the springs ensures that your garage door system will function like new once again.

Inspect and Lube

Manually raise your garage door then lower it. Raise it half way and release it to see, if the new springs hold it in place. Check its balance and ensure that it is functioning properly. Lastly, engage and reengage your garage door prior to reconnecting the power to automatic opener.
