How to repair garage door spring
For purposes of repairing a garage door spring, there are two main stages you must put into consideration, first of all, being the removal of the old spring and then installing a new spring.
Removing the old spring
- First of all, remove the door opener’s plug and then clamp the track and the door together to prevent the door from opening on the release of the spring.
- Hold each spring using a winding bar while loosening the set screws. For safety purposes, have the sturdy ladder positioned to the springs’ side.
- Using two winding bars, unwind each spring, positioning into a hole on the cone, the second winding bar perpendicular to the first one.
- Make the springs slide up to the end bracket after removing the bolts as well as the nuts.
- Put the torsions’ tube in a secure position preventing it from moving and then untighten the set screws on the lift cable drums using a wretch. Make the cable drums and springs slide off the torsion tube after disconnecting the lift cables.
- Take the measurements of the length of the spring when it is still relaxed since having the measurements when it is installed may be inaccurate due to the existing tension on them. The measurements should be taken in inches for purposes of ordering replacements. Ensure that the spring you are measuring is not broken.
- Use a tape measure to determine the diameter size of the spring as well as the size of one coil, which is gotten by dividing the total length of the coils by the number of coils.
- Make orders for replacement springs online since it is difficult to have them from manufacturers and distributors if you are not a professional. Ensure what you are ordering is compatible with the measurements of your spring because any slight difference can cost you another order.
- Ensure you make any necessary replacements before installing new springs to avoid dismantling the door again and starting from zero.
Installation of new springs
- Insert the left spring into place on the torsion tube and then have the bar inserted into the left bracket after replacing the cable drum.
- Install the spring on the right as well as the bearing at the center and then have the bearing pressed into the cones at their stationary point.
- Fix the cables and make the drums tight.
- Following the supplier’s recommendation, wind the springs.
- Stretch out the springs from the center by tapping the winding bar using a hammer
- Tighten each set screw until they contact the tube. Do not make them too tight because this may distort the tube.
- Use a garage door in lubricating the springs on both sides and ensure the excess is wiped off.
- You can now safely remove the tools you used in holding the bar and the garage door, which may be pliers or even clamps.
- The final step is to check if the garage door is now properly working. You just lift the door high about 1m and let it go. If it does not go down, then you can now have the opener plugged back, but if not, add another turn to each spring.
