  • Double life torsion springs; are indicated for this job. Extension springs cable are also used for garage doors. You can replace a garage door extension spring cable.
  • Lifting cables or safety cables; the more length they contain, the better. If leftover, they will be cut at the end of the job.
  • At this moment; we have what we need to begin our repair, carefully following the steps that we will show:

Step 1: Secure and close the garage door. 

Before we start, if your car is in the garage, we recommend you remove it and leave all the space available. To execute the steps, have the safety implements on, glasses, gloves, and boots.

  • Using the locking pliers, obstruct the rollers to prevent the door from moving. Next, you must unplug the garage door opener and place the door in the down position.
  • To unwind or vice versa, the torsion spring; use the professional winding bar set. 
  • Place the ladder next to the ends of the spring, never facing it or the stationary cones of the horizontal track; when starting the winding process. When finished, remove the ladder, and test the door to make sure it does not move.

Step 2: Loosen the spring.

Using the winding bar, insert it into the lower hole of the winding cone of the spring. Attach the bar. You can use support hardware; followed by loosening the set screws, use the appropriate wrench. Be careful as you loosen and avoid injuries. The spring will push you by the pressure when loosening the screws.

Step 3: Insert the second bar.

Guiding you clockwise in the normal cycle, place the winding bar at 9:00, pull out the lower bar, and unwind the spring a quarter at a time with patience. You must be careful and patient when you are unwinding the spring.

Step 4: Subtract bolts and nuts ‘to disconnect the broken springs from the center support.

Remove the two nuts and bolts that hold the stationary spring cone to the centre support. Then, with extreme care, slide the springs into the end supports.

Step 5: Lock the torque tube.

Using the locking pliers on the centre support, clamp the torque tube in the support. In doing so, loosen the set screws on the left and right hoist cable drums, disconnecting the hoist cables.

Step 6: Remove the spring to be replaced.

Starting from the left side of the door, slide the torque tube to the right; so you can remove the cable drum. Next, carefully slide the old spring out of the tube.

Step 7: Install the left spring.

Place the new replacement torsion spring into the torsion tube with the fixed cone towards the centre bracket. In this way, reinstall the cable drum with the garage door wire. Then insert the torsion bar into the left side bearing bracket.

Step 8: Install the right spring and a new center bearing.

Slid across the centre bearing to force the torsion bar to the left and push the belt into the fixed cone, install the correct spring. Reinstall the drum and connect both stationary cones to the centre bearing.

Step 9: Replace lower brackets, rollers, and cables.

Place the hoist cable loop over the pin; of the new bottom bracket and pulley, check that it is securely shimmed. Install the new roller and replace the lower brackets and cables.

Step 10: Anchor the cables in the safety groove of the drum.

Route the lifting cables up between the rollers and the door jamb. In this way, move the top of the lifting cable through the cable drum slot.

Step 11: With equal tension, tighten the drums.

Position the locking pliers; on the torque tube to secure it in place while tightening the drums. In this way, twist the drum to wind the cable into the grooves. Stretch the cable as tight as possible before tightening the locking screws. Without moving the locking pliers, repeat the procedure and tighten on the other side. You must apply the same tension on both sides; otherwise, the door will open unevenly.

Step 12: Coil garage door springs with the same tension.

Place a winding bar on the cone; coil in the direction of the ceiling, move the spring a quarter turn at a time, with twisting motions. In this way, you will jump the winding bars as you go. Taking specifications; follow the spring supplier’s recommendations for the total number of turns. If not available, make 30 quarter turns for a 7-foot high door, and 36 quarter turns for an 8-foot high door is the standard.

Step 13: spring stretching.

The spring must be completely wounded. Tap the roller bar to extend the spring — about 1/4 inch — from the centre before pressing the set screws. Move the set screws in a twisting motion; until they contact the torque tube. Then tighten the set screws one-half to three-quarters of a turn.

Step 14: spring lubrication; use garage door lubricants.

Apply to the entire spring area the required lubricant; remember to cover with rags and wipe off excess rungs.

Remove clamps, torque tube pliers, and track, lift door approximately 3 feet by hand. Otherwise, the door drops, add a quarter turn to each spring; repeat if necessary. In this manner, if the door continues to open on its own, release the spring tension in quarter-turn increments until the door remains in place when released. Then reconnect the opener.
