If the spring has snapped, it will not need to be unwound. In a dual spring system with one spring broken, however, it is always recommended to remove and replace both units. The main part of unwinding the spring involves becoming comfortable with handling the torsion with the following steps:

Knowing the spring – Dual garage door springs have two sides – a stationary end located near the center and a winding end towards the outside. The winding end contains a winding cone with numerous slots where the winding bars will be placed to loosen or tighten the spring.

Setting the first winding bar – Make sure to wear safety glasses and work beside (not in front of) the spring for maximum safety. Set the first winding bar in the slot facing out until it clicks and move it up and down just a bit to get comfortable with the torsion. Hold the bar and loosen the 7/16” set screws so the spring can be loosened.

Unwind – Bring the first winding bar down and keep it held in place. Set the second winding bar in the next slot up then remove the first bar. Bring the second winding bar down to complete two quarter turns. Repeat this process 30 times until the spring is out of torsion.

Loosen Stationary Side – After removing the torsion from both sides of the spring, prepare them for removal by loosening the 9/16” bolts on the stationary sides of the springs.


After the springs have been fully unwound, they can be removed and replaced in a few easy steps:

Mark the drum and shaft (torsion bar) – The drums are the two circular pieces on either side of the garage that the cables are wound around. Make a Sharpie mark on both the drum position and where it meets with the shaft will make for easier alignment when the new springs are attached.
Remove cable – Unhook the cable from the drums and place it in a slot on the garage so it doesn’t get damaged.
Loosen drums – Take a 7/16” wrench and loosen the drums on both sides of the garage.
Remove drums and springs – Once the drums are both loosened, the shaft can be pushed through on one side for removal of the drums, springs, and any bearings. Make sure to keep the bearings in case they aren’t included with the new set; otherwise, toss the spring so it isn’t stepped on later.


Putting on the new springs largely involves doing everything that was just done to take them off:

Red is RIGHT Wound, but goes on left side – One thing to remember with garage door torsion springs and end drums is that they have paint marks on the end for a reason. All the red pieces should go on the left side of the garage when looking up from the interior. So in this case, put all the pieces back on the shaft so when looking at them from left to right they go: red drum – red spring – center bearing – black spring – black drum.

Set the Stationary Center – The centers of the springs need to be set in place before they are wound back tight. Make sure the center bearing is sitting on the lip of the bracket coming out from the garage wall and align the two springs while tightening them with a 9/16” wrench. To know how far out from the wall to place them, measure the distance of the shaft to the wall at each end and mimic it.

Place Cable and Tighten Drum – Insert the cables back into the drums on each end and wind them until they’re tight – making sure to realign with the previous black Sharpie marks. Push the drums tight against the end and tighten the 7/16” bolts. Next put some tension into the spring by spinning the shaft until the cable is tight. Keep that position by clamping a vice grip on the shaft and positioning it against the garage door so it won’t move while tightening the springs. Follow that by tightening the second drum.


A rule of thumb with springs is that four quarter turns equals a full revolution and the spring needs to be tightened a full revolution for every foot of

door height (e.g. 7-1/2 foot door = 7 revolutions +2 (30 quarter turns).

One way to help remember how many turns have been completed is to paint a line down the width of the spring. As the spring reaches its tightening point, there will be 7-1/2 gaps marked out in the paint.

Wind the Spring – This time use the winding bars upwards to tighten instead of loosen the spring. Place a winding bar at the bottom and bring it ¼ turn up. Place the second winding bar in the winding cone slot that is now at the bottom, then remove the first bar. Complete this process for the required amount of turns.

Tighten the Set Screws – Pull the winding bar up a bit and tighten the set screws ¾ of a turn past tight. Complete the tightening process on the spring on the other side of the garage.


With both springs tightened, it is time to check the work. Remove the vice grips on the shaft and lift the door halfway. The door should stay in place wherever it is positioned. If it is too heavy, torsion needs to be added, whereas if it’s too light, torsion needs to be taken away.

Two other things to check: Is there cable tension when the door is up? (There should be.) How far does the door rise when it’s lifted? It should be flush with the door as over-travel adds extra tension to the spring and reduces the lifespan. All of these can be remedied by either winding or unwinding the springs, or in some cases purchasing a different size of spring.

Once the door is balanced the final steps involve pulling the cord to put the door back in auto mode, plugging in the opener and pushing the button to hook the door back up to the carriage. The springs can then be lubricated and should be ready for action.

It’s an advanced DIY job, but repairing broken garage springs doesn’t have to be as intimidating as people make it out to be.
