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