Changing your torsion spring
There are two basic different types of door springs:
the torsion based or side mounted.
If you own a torsion garage door opener, then before you get down to replacing or adjusting the garage door opener, you should understand the basic stracure of the unit.
The torsion springs are placed on a fixed metal shaft located just above the top of the frame for the garage door. The springs extends by the length of the shaft and they both twist as the garage door will shut or open through a set of cables that are attached to either side of the lowest garage door .
The tension produced in the cables will help to lift the door from a closed position. If you never bought a garage door opener and you are thinking about buying one, then you can get yourself one that comes with adapters and a drill. These are much simpler to adjust than the traditional models. Let us first be clear that adjusting a torsion spring manually can be risky as you will have to do this with the door shut and the spring under tension. So before you start make sure that you have all the tools you need . This is true for those who do not have an alternate door for entring and exiting the house. The first thing to do is to secure the door by putting a clamp on the track of the garage door under the roller that is located at the very bottomof the garage door. Since you have to adjust the spring tighter, there is always the possibility to overtighten it which can be disastrous as the door may rise. The end of the spring that moves is to be attached to the adjustment collar. . The adjustment collar comes with a series of holes and you need to insert the rod through one of these holes. When the adjusting rod has fitted in tightly to the hole then the set screw is relaxed and the rod is used to turn the collar so that the tension in the spring is either increased or decreased as per your needs. call chula vista garage door repair for more info
