2.3 Beware of older winding cones. These older Crawford and McKee torsion spring cones were made for 5/8" bars. Sometimes, however, the holes are too small for 5/8" bars. Whatever you do, don't use a 1/2" bar; instead, grind down a 5/8" bar to fit. I recently had a McKee spring let loose after winding because I used a 1/2" bar when my 5/8" bar wouldn't fit. Just before it let loose I was telling myself, "This is not safe." And it wasn't. The only safe way to replace these older springs is to make a winding bar for each hole of each cone.
9.13 If you have a spring anchor bracket with a fixed steel bearing, check for wear at the point where the shaft and bearing race meet. The shaft needs to be free to slide sideways inside the bearing. File the shaft if needed. Lube the bearing. Notice that only one bearing is needed for two torsion springs. This bearing keeps the shaft from rubbing against the inside of the stationary cones and on the center bracket. Your garage door may not have a center bearing. If so grease the shaft where it will be rubbing the bracket and the insides of the cones.
When a torsion spring is wound up, it grows 2” in length. This is because the spring starts to compress and the metal has to go somewhere. After the spring is wound, the winding cone is clamped down on the torsion shaft so it can turn the drums to wind the cables as the door goes up. Since the end of the spring is “set” on the shaft, a two-inch gap is left when the spring break's. This is the most definite way of determining you have a broken garage door spring.

Both types of springs are _loaded_, or under tension, when the door is closed. This gives them stored energy to help lift the door as it's being opened. When the door is all the way up, the springs are relaxed, or relatively so—they still may be under some tension. The mechanical difference between extension and torsion springs is that extension springs are loaded by stretching, or elongating, while torsion springs are loaded by twisting, creating torque.

10.3 At this point you will wind the spring. Notice that the end of the spring on the winding cone points up when facing you. You will wind both springs up and counter intuitively as if you are trying to unscrew the winding cones from the ends of the springs. Begin by turning the spring up 1/4 turn until it meets resistance. This is your first quarter turn. Count "one." Next, insert the bar and raise it 90 degrees. Insert the second bar. This is "two." As you wind the spring it should grow in length the thickness of one coil for every turn. The cone should cover your mark after the first couple turns. Many garage door tradesmen mark the torsion springs with chalk or paint, but this often generates confusion.
If you're like most people, your garage door is your primary entrance to your home. It's convenient to use and parking in the garage provides protection from the elements. Garage doors have several moving parts, including the door springs that help raise and lower the door. These springs do eventually break down, leaving the door inoperable. When this happens, it's time to repair or replace the damaged parts. This cost guide shows you what it costs to hire a professional to repair or replace any garage door spring.

In addition to the bodily risk involved, it’s simply not an easy task. There’s the possibility that you will not install it correctly. At worst, this creates the risk that the mechanism will fail at the wrong time and injure you or someone in your family. At best, this means it will malfunction, and you’ll have to call professionals to fix it. It will save time, money and potential heartache to simply call a professional to install your new door springs correctly the first time.
Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break.
