Slide the left spring onto the tube and add the cable drum. When your new springs arrive, put the new left spring (the 1 with the end facing up and to the left) on the torsion tube, making sure that the stationary cone on the end of the spring faces the center bracket. After sliding the new spring into place, replace the cable drum and insert the torsion bar into the left bearing bracket.[9]


Keep in mind, the pulley is often cycled through an enclosed casing that is difficult to lubricate directly. By applying enough lubricant to the pulley, you’re ensuring that the whole lifting mechanism is properly lubricated. Furthermore, a jam in this portion of the lifting mechanism is a time-consuming and potentially labor expensive repair that requires a service professional.

Garage door springs come in two styles: torsion (see above), which mounts on the header above the door, and extension (Photo 1), which floats above the upper roller track. In the past, extension springs were safer to install but didn’t have containment cables running through the center of the spring. Without cable, these springs become dangerous, heavy whips when they break. They also tend to be noisier than torsion springs, and we recommend you use them only if you don’t have the 12 in. of headroom above the door that a torsion spring requires.


In this article, we’ll tell you the difference between a safe door and one that’s unsafe. We’ll also give you the helpful tips you’re not likely to find in the manufacturer’s instructions to correctly, and safely, install a new garage door with a torsion spring and do-it-yourself tensioning. Installing a new, double garage door yourself will save you several hundred dollars and should take eight to 12 hours if you’re fairly handy. You can do most of the new garage door installation project yourself, but you should recruit help for removing the old door.


No matter what kind of door you are installing, be very careful. The instructions that follow are merely guidelines. You should read your garage door manufacturer's instructions and owner's manual very carefully before attempting either type of installation. And if you're a do-it-yourself greenhorn, skip this project and hire an experienced professional. It may be more expensive, but garage door installation is on the higher scale of DIY difficulty.
