Standard Torsion Springs with cones priced with free shipping in the United States and with free
pair of Winding bars. Order today.
Winding Bars will be needed to do the
job safely and properly. Comes with each purchase.
WARNING: The torsion
spring is under high tension and requires special tools for adjustment. Because of this tension, the torsion spring and any
part associated with the counterbalance system should be adjusted only by a professional. These parts include: springs, cables,
corner brackets attached to the cables, cable drums, and the center bearing bracket that holds the torsion spring shaft. You
are repairing this at your own risk and we our not responsible for any injury do to improper installation or lack of skill.
Garage door torsion spring repair Warning: Before purchasing and installing your springs
or other parts, make sure you use the proper tools and follow these directions carefully.
Tools needed for overhead garage door torsion spring replacement:
- Winding
bars or sometimes referred to as torsion bars
- 7/16" or 3/8" open end or combination wrench
- 9/16"
open end or combination wrench
- maybe a hammer
Step 1 Simple torsion spring
change begins with removing old springs. You should have either one or two springs on your system and the garage door should
be closed. If you have a two spring system the chances are that one of your torsion springs still has tension built up in
it. "do not loosen any screws until tension has successfully been released from the system". Insert winding bar
into the spring that still is under tension, wind the system in the upwards tightening direction approximately 1/4 turn until
you can insert the second winding bar (the purpose of this is to safely lock winding bar against the door.) Note: always insert
the winding bar fully.
when torsion system is firmly locked against the door
you can then loosen the two 3/8" square nuts that are on the winding cone. Next slowly walk the
spring in the downward direction utilizing the winding bars until the spring tension is completely removed. Once all tension
is removed from the system you can safely loosen the 9/16" nuts on the center bearing support bracket. next loosen the
3/8" square nuts on both drums (just loosen until drum spins on torsion tube, do not remove them). Loosen the remaining
square nuts on the other spring. (if the spring is broken in the middle than it obviously will not be under tension so it
wont be necessary to use the winding bars on it.) Ok at this point you can slide the torsion tube out of the end bearing plate
and rest it on the j-arm (connector between door and motor). The drums and springs can now be slid off of one side. If
you have a center bearing bracket that does not have an opening then you will just have to slide the parts off one side at
a time. none the less is almost never necessary to remove the end bearing plate. note: if it is tough to slide the springs
try to hit them with a hammer.
Step 2: Now carefully looking at the diagram
above slide the new parts on the tube and insert the tube into the end bearing plate... note: the rule is "red is never
right" so from the inside of your garage looking a at your torsion system you can determine right from left. At
this point you should have a setup that looks like the above diagram. insert the 9/16" bolts and secure them with the
corresponding nuts. You are now ready for applying torque to the system.
Step 3
Choose which spring you would like to tighten first it does not matter either way. Insert your winding bar and start winding
upwards in quarter turn increments. The rule is "one full turn per each foot of garage door height" In other words
a seven-foot-high garage door would have seven winds on the spring... note: one full turn is equal to four quarter turns...
With galvanized springs it is a good idea to put an extra half turn on each spring to achieve the best balance..
Garage
Door spring repair continued
Important: after tensioning one spring lock it against the door with
the one winding bar inserted into the cone... Then tighten the square set screws first by hand until they hit the
tube, then with the 3/8" wrench two-and-a-half-turns so its snug not to tight to where it crushes the tube.
now
your set screws are tight and there is built up tension on one spring. Now you can insert the cables into the drums; spin
the drum so that the cable winds up on the drum the left drum wraps counter clockwise, and the right clockwise. Hold the drum
such that tension is on the cable while simultaneously tightening set screws the same as before. At this point with both cables
on the drums you should now be able to remove the winding bar thereby distributing the torque of the tightened spring
onto the cables. note: some people use vice grips but and tighten the drums first but it is not necessary with this easier
more efficient method.
at this point you can wind your second spring using the winding method above and
tighten the set screws on it. your door should now be balanced.
After the job is complete always check
that the door travels smoothly and balanced by hand before attempting to use the motor.. this will help you prevent damaging
the motor as you will see if there are any noises or if the door is hitting anything on the way up.
These are basic instructions. There are variables that can make this job more complex thus encouraging you to call
a professional.
