   • Lighter and smaller doors may but have a single torsion jump, while larger and heavier doors may take two springs, with one located on either side of the primal plate.

   • The rods or confined should exist 18 to 24 inches (45.7 to 61 cm) in length.
   • Solid steel bars tin can be purchased at hardware stores.
   • You volition demand to measure the diameter of the holes in the winding cone (the collar that secures the spring to the metal shaft) to determine what size bar or rod to use. Near cones have a pigsty diameter of i/2 inch.
   • Do not try to utilize whatever sort of tool as a substitute for the winding bars or steel rods.^[6]

1. 1

   Open your garage door fully. Before y'all can work, you need to release the tension on the springs. Open the door until information technology hits the stop bolt and can't go any further. For an automatic door:

2. 2

   Secure the door in place. Identify a C-clamp below the bottom roller,^[9] or use two locking pliers (ane on each track under the bottom rollers).^[10] This will ensure the door doesn't autumn while you are working.

3. 3

   Remove the spring hook. The spring will be attached to the rail hanger past a big claw that's kept in place with a nut. Once there'southward no more tension on the spring, remove information technology from the track hanger. Apply the adjustable wrench to remove the nut on the back side of the subclass.

   • You'll at present be able to move the hook to a lower or higher hole to subtract or increase the tension.

4. iv

   Adjust the tension. To make sure yous achieve the right tension, adjust the spring by one hole at a time.^[11] Adjust both springs equally, i at a fourth dimension, if your door was balanced. Once you lot've moved the hook to its new location, replace the nut on the back and use the wrench to tighten the claw into place.

   • To decrease tension and set up a door that isn't closing fully, is difficult to close, or opens too rapidly, hook the spring onto a lower hole on the track hanger. This reduces the length of the spring and the tension on it.^[12]
   • To increase tension and gear up a door that is difficult to open up or closes likewise quickly, claw the spring onto a college hole on the runway hanger. This stretches the spring and increases the tension on it.^[xiii]
   • To adjust tension on one side and correct a door that wasn't endmost evenly, conform the leap only on the side where the gap was. Decrease the tension on that side past hooking the spring onto a lower pigsty on the track hanger.^[14]

At the end, there will exist a winding cone keeping information technology in identify. The cone volition have four holes evenly spaced effectually it, plus two set screws that are used to lock the spring in place on the center shaft.

   • To change the tension on the jump, you volition be adjusting the winding cone by inserting the winding bars into the holes and rotating the cone in 1 direction or the other.

4. four

   Loosen the ready screws. Insert the winding cone or solid steel rod into the bottom hole on the winding collar.^[eighteen] Concur the cone in place with the bar and loosen the screws.

6. 6

   Adjust the tension. Make sure the bars are fully inserted, and manually rotate the cone in 1/four increments.^[21] To determine a 1/4 plow, rotate the winding confined 90 degrees.

   • To increase tension for a door that'due south difficult to open or closes too speedily, wind the cone upwardly^[22] (in the same direction as the garage door cable goes through the pulley).
   • To decrease tension for a door that isn't closing fully, is difficult to close, or opens too apace, current of air the cone downwards^[23] (in the contrary direction from how the garage door cable passes through the pulley).^[24]

With the bar notwithstanding in the bottom hole, pull slightly upward (toward the ceiling) on the bar and toward the center plate. As you lot do this:

   • Go on property the bar up and over and tap on it with the second bar. Tap it just beneath the winding cone. Tap it away from the center plate and toward the mark on the shaft.
   • Tap the bar until you have stretched the spring to meet the mark on the shaft.

8. 8

   Tighten the set screws. Once you've stretched the bound out ane/4 inch, concur it in place with the i bar and lock information technology in place on the shaft past tightening the gear up screws.

   • Make sure you supervene upon the screws into their flats if there were any on the shaft.

9. 9

   Echo on the other side. Some torsion spring mechanisms have two springs (one on either side of the center plate), and if this is the example, repeat steps iv to eight on the other spring. Torsion springs must be adapted every bit to ensure balance.^[25]
