11.2b If the springs you installed are too strong, and if you wind the springs the correct number of turns, the door will not stay down nor half way. The garage door will be hard to close. DO NOT REMOVE MORE THAN HALF A TURN OF SPRING TENSION TO CORRECT THE PROBLEM. Here's why. If you remove 3/4 of a turn to get the door to stay closed, and then if you open the door, it will get heavier as you open the door, and once open, the cables will come off the drums. This could create as much as a day's extra work. It could also cause door damage and/or result in serious injury. Do not use the door! Get different springs!
Doors with extension springs have two sets of pulleys (which are sometimes called _sheaves_): one at the end of each spring and one at the top of the vertical door track. They also have two cables on each side. One cable attaches to the bottom of the door, runs up and over the pulley above the door and around the spring pulley and then attaches to the door track bracket. The other cables are safety cables that run through the middle of the springs and are fixed to a track bracket at both ends. These cables restrain the springs if they break under tension. All extension springs must have safety cables.
7.3 Slide both torsion springs out above the top of the garage door toward the cable drums. Notice that there is only one bushing or bearing between the cones. Sometimes a single bearing is pressed into the bracket; other brackets have a single bearing or bushing that fits in either cone. Do not try to install a bushing or bearing in both of the stationary cones. You will risk breaking a cone. The purpose of the bushing is to keep the shaft from wearing against the spring anchor bracket. Only one bushing is needed to accomplish this.

7.4 Check to make sure the torsion hardware is secure. If needed tighten the lag screws that attach the spring anchor bracket to the header. If loose, replace with longer or thicker lags. Brackets for doublewide wood doors should have two lags on the bottom, because when the springs are wound the spring torque pulls the bracket from the bottom. Never touch these when the springs are wound. One of my customers removed the screws when the springs were wound. He broke his arm in 14 places and almost died. He spent a month in the hospital.
Scott was exceptionally polite, professional and knowledgeable. He thoroughly checked my garage door opener, but also inspected the garage door itself and pointed out rust and deterioration that has occurred. Scott then gave me a quote on a new garage door, explaining the installation procedure and quality elements of the new door including the warranty. I was very pleased with the entire service appointment, and my husband and I are seriously considering the new garage door, but only if Scott is the installer! Thanks, Scott!
If you have two torsion springs on your garage door, the good spring will most likely keep the cables on the drums when the other spring breaks. This makes it much easier to lift because the good spring will be pulling half the weight of the garage door. You can also use the garage door opener to help assist while someone lifts the door and acts as the broken spring. Use extreme caution when doing this to prevent damage to your garage door or injury to a person.

4.4 Take the spring on the left and place it at the left end of the door as pictured here. Notice that the end of the wire points to the right toward the center of the door. This is a right wind torsion spring. It will go above the garage door on the left side of the spring anchor bracket. The winding cone at the other end of this spring is usually painted red.
