Torsion garage door springs have cones at both sides. At one side, there
is a stationary cone. This cone doesn't move. It keeps the spring still on this side. On the other side,
there is a winding cone. The spring moves at this side. It actually unwinds and
winds in order to open and close the door. The power of the spring comes from
the torque created when the spring moves on one end. The movement is
transferred to the shaft, which is the metal bar passing through the spring.
Since the shaft is connected to the garage door cable drums at the two sides,
it transfers the spring movement to the drum which pulls the cable up. This is
the way the door opens.
So, the importance of the stationary and winding cones is great for torsion
spring garage door systems. They help the spring move the right way and develop
torque. Actually, the winding cone has great significance for all repairs
related to torsion springs. This cone is used to unwind springs when their
tension must be released and wind up springs when tension must be added. This
is how garage door torsion spring adjustment is done and actually there is need
to use winding bars, which are inserted in the little holes on the cone so that
the spring can be adjusted or its tension released so that the spring can be
removed and possibly replaced. Winding bars come out in different sizes so that
they can fit in the size of each winding cone.
Torsion spring cones replacement requires proper tools
When you buy torsion springs, they don't necessarily have cones on them. You can buy them with or without
cones. This gives you the chance to have the winding and stationary cones
replaced if they are damaged or rusty regardless if you will replace the
spring, too. So, the first step is to remove the torsion spring. This is one of
the hardest garage door repairs since it involves high risks due to the great
tension springs are under. So, if you feel uncomfortable with such tasks, trust
the service of Garage Door Repair Layton. In order to remove the spring, you
must unplug and disconnect the opener and keep the door closed but also steady
with c-clamps over the rollers. With the help of two winding bars, unwind the
torsion spring till its tension is released. Torsion springs are unwound by placing
the first winding bar in the winding cone, loosening the setscrews, using the
second winding bar to turn a bit the cone, placing the first winding bar to the
next hole of the cone and so on until the spring is unwound and ready to be
removed.
Once the spring is removed, it must be gripped so that you can use a
pipe wrench to turn the stationary cone till it comes off. You must pay
attention. Once the cone is free from the spring, it will pop out and so you
must stand off its way. Use the same steps in order to remove the winding cone
on the opposite side of the spring. Now get the new cones and place them on the
edge of the inside tube. Use one hand to push the cone and the tube inside the
spring and the other hand in order to start screwing it till the end part of the
cone finds the end part of the spring. Mind you that attention is needed when
you are installing the new cones. For your convenience, mark which side of the
spring had the stationary cone before and make sure both the stationary and
winding cones are installed at the right size or you will have a problem placing
them. Then you must reinstall the spring and connect all parts before you try
out the door.
