Let’s get into how to repair a broken torsion spring first. This is one of the most used parts of the garage door and hence may need frequent maintenance.

Step 1:
springs in order
You will have to release the tension that is present in the springs in order to remove them. To do this, Place one of the winding bars in one of the holes in the winding cone of the spring and release the tension slowly one-quarter turn at a time. Then you must release the springs from the centre cone with a 9/16-inch wrench or a 1/2-inch wrench.

Step 2:
Use your vice grips
Use your vice grips to clamp the torsion shaft to prevent it from dropping when you take off the old springs during the garage door repair.

Step 3:

Then Loosen the keys on the old spring and slide the spring towards the end, then loosen the keys on the drum and remove the cable. Then slide the drum towards the centre of the torsion bar. Do this on the other side of the garage door too.

Step 4:

Then slide the torsion shaft towards the centre of the garage door and remove the drum and slide the first spring off. Also, make sure that you are using the correct springs for both sides. The left side spring has black paint, and the right side has red paint. The wire should come over the top of the spring.

Remove the vice grips that you placed during the garage door repair from the middle of the torsion shaft and bolt the springs to the middle bracket. Be careful with this step. See that the garage door is properly holding itself before you remove the grips completely.
