How to adjust garage door tension.
How to determine garage door tension force.
Measure the distance from the top of the closed door to the bottom of the horizontal track.
Spring length how long each spring is 4.
You need proper tension on a garage door to operate the door by hand or with an automatic opener.
When the garage door is closed the torsion spring is in its deflected condition torqued up.
1 divide the total spring s ippt by the cable drum multiplier 2 multiply the spring ippt by the number of turns and then divide by the hi moment arm.
Torsion springs and garage door weight torsion springs need to provide enough force to equal the weight of the door.
The spring s individual measurements are also important they determine the spring s lift.
Inside diameter 90 of doors have a 2 0 inside diameter 3.
When the garage door is open the spring is in its equilibrium state natural condition.
Use this method if the door worked correctly before the spring s broke and the garage door has not been tampered with.
If the tension is too loose the springs that help lift the.
During the twisting motion of the torsion spring it exerts the force required in order to keep the door balanced and light to operate.
This is sometimes referred to as the spring s lift power how much weight the torsion spring can lift.
On the contrary it is very simple to determine the winding type of a garage door spring.
Continue making minor adjustments with the cable and testing the door until it s correct.
This method of measuring your torsion spring requires you to measure the existing springs.
With most new garage doors there will be two torsion springs separated by a divider that s located at the midpoint of the door.
Spring orientation only worry about this if you have a 1 s.
This video applies t.
Inch pounds per turn.
Determine if your door is opening and closing the way you would like and ensure it s balanced closes evenly and without gaps.
Force spring exerts per 1 turn of the spring.
The right hand winding springs are wound in a clockwise direction.
On the other hand a left hand winding spring is wound in an anti clockwise direction and has its end of wire on the left side.
Thus they have their end of wire on the right side.
The spring to your right is a left wound spring and the spring to your left is the right wound spring.
