The torsion springs are 90% responsible for the proper functioning of your garage door. Due to the strain, the torsion springs are prone to wearing out quickly. You will need to replace the torsion spring of your garage door if it is broken. You can do it yourself or hire a professional to change it for you. The torsion springs are under high tension and replacing it is a highly dangerous job that requires you to be very careful. If not done well, it can result in grievous harm or even death to you and destruction of your property. If you are not certain that you can change the springs well, you should hire a professional. You are required to read and understand the instructions before attempting this work. Also ensure that you use the right tools.
The following is a list of tools you will be needing to complete the job:
- A sturdy ladder
- Safety glasses
- Tape measure for taking measurements
- A black marker to mark measurements taken
- A metal rod in which to wind the broken torsion spring onto
- An adjustable wrench aka “crescent wrench”
- Replacement torsion springs
Here are the steps you need to follow when replacing the torsion springs:
- First, close the garage and unplug the door opener. Clutch the bars firmly on both ends cones. Keep your head away from the way of the winding cone, while you unwind the spring. Position yourself safely on a sturdy ladder. Wear safety glasses. Keep your clothes away from the springs.
- Take the measurements of the old and new springs to ensure you have the precise springs. Make marks on the drums and torsion shaft at each end to help you level the garage door after installing the new torsion springs.
- Stand firmly on a ladder and insert a well-fitting rod into the winding cone and unwind the broken torsion spring. As a precaution do not wind or unwind the springs using a screwdriver. Make count of the turns you make to unwind the spring, so that you will know how many turns to make while installing the new spring.
- Carefully remove the springs out towards the cable drum, and loosen the screws on the cable drum on the left garage door and ensure the drum can easily turn. Then take away the cable from the left of the drum.
- Remove the cable from each sides of the drum. Unbolt the drum from the pole and take it off. Replace the new springs by first sliding the drum away from the bearing plate and slide the shaft to the left.
- Lining up with the markings you made earlier, re-install the torsion hardware by sliding the drum on the shaft, and then slip the shaft on the bearing. Then fasten the set screws into their original dent while rotating the drum to find the slots. Make sure the screws meet the shaft.
- Ensure that the new springs are properly installed on the exact sides of the center bracket. Then wind the springs.
- Remove the vise grips holding the garage door and slowly check to see if the door is functioning properly. Apply the recommended oil to the springs. Finally connect back the opener and plug in the power cable.
