How to Replace Garage Door Springs

There are two standard types of garage door spring used in designing garage doors. These are side mounted and torsion. Torsion springs are affixed to the stationary metal shaft situated above and parallel to the upper portion of the door frame. These are connected by one end of a metallic plate that is stationary and located atop the center of the garage door frame. The springs stretch alongside the shaft. They function by winding as the door closes using cables affixed to the side of the lowest door panel.  The garage door is much easier to lift from the closed position with this tension. It is generally recommended that individuals consult a professional contractor to adjust or replace torsion springs. 


Side mounted springs are long, heavy, metallic springs affixed to each side of the upper door track. These function in the same capacity as torsion springs; however, the side mounted spring type utilizes a pulley system. The tension used to lift the garage door is produced when the door is closed. It is important to note that all types of garage door springs should be replaced in sets.


Replacing the springs - step by step


It is first necessary to release all tension from springs prior to replacing them. This may be accomplished by opening the door as wide as possible. This will be when it touches the stop bolt attached to the track. A C clamp may be attached to the track on the spot under the lowest roller to fix the door in this position. The tension should still be released in the springs of a garage door with an opener. There is an emergency release cable which will disengage the opener from the door. Pull this cable and push the garage door to its upper most point without actually causing any damage to it. The C clamp may now be used in the method described above.


Any and all safety cables must be detached and removed from the door springs. The existing springs should be connected at two points. One end should be a stationary attachment mounted to the door track or a wooden frame. The opposite end will be affixed to a pulley which guides the door cable. Disengage both of these and reconnect the new garage door springs. Do not twist the door cable during the attachment of the pulley.


One piece of excellent piece of advice is to examine the pulley while it is disconnected. Replace the pulleys if they are wobbly or the bearings are worn. These cannot be repaired; they must be replaced entirely. This will cause the door to function much smoother. 


Once all of the hardware except the safety cables has been reattached, it is time to test the door to ensure that it is functioning properly. If it is difficult to close the garage door completely, the new springs may require some adjustment. It may be necessary to loosen the naked base of the cable attached to the door track one or two inches. This cable base may be connected by an S hook, looped through holes of the track, or another type of clip. It must be adjusted equally on both sides by placing the S hook in another hole or by reducing its length. When the door is closed the springs should be in symmetrical positions.
