SPRING REMOVAL
STANDARD
TORSION SPRINGS
TORSION SPRINGS CAN BE VERY DANGEROUS AND MAY CAUSE SERIOUS INJURY OR DEATH IF THEY ARE
IMPROPERLY INSTALLED OR MISHANDLED. DO NOT ATTEMPT TO INSTALL THEM YOURSELF UNLESS
1) YOU HAVE THE PROPER TOOLS, REASONABLE MECHANICAL APTITUDE AND EXPERIENCE, AND UPPER
ARM STRENGTH, AND 2) YOU FOLLOW THESE INSTRUCTIONS VERY CAREFULLY. PROFESSIONAL
INSTALLATION IS RECOMMENDED. DO NOT ATTEMPT TO REMOVE TORSION SPRING TENSION IF
THE WOOD MOUNTING PAD CONNECTING THE BRACKET TO THE CENTER OF THE SPRINGS IS SPLIT
OR ROTTED, OR IF THE FASTENERS AT THIS POINT ARE LOOSE OR MISSING.

HOW TO REMOVE TENSION FROM REMAINING SPRINGS IN ORDER TO WEIGH DOOR
These instructions apply only for the purpose of removing tension from torsion springs (springs mounted to the front header
of the garage). Use only torsion spring winding bars for removing and adjusting standard torsion spring(s). DO NOT USE ANY
OTHER TYPE OF TOOL FOR WINDING OR UNWINDING STANDARD TORSION SPRING(S). If the door has two torsion springs and
only one is broken, always replace both springs.
TOOLS NEEDED: Adjustable wrench or 3/8" open end wrench
C-clamp or locking pliers
Two solid steel winding bars (available for sale at Menards)
STEP 1: Disconnect the garage door opener; lock the door securely in the down
position using the door lock, C-clamp or locking pliers placed directly above a
roller. This must be done to prevent the door from prematurely opening which
could cause injury.
STEP 2: If the door has only one spring and it is broken, proceed to weigh door.
If there are two springs, the remaining unbroken spring must be unwound and
replaced. Proceed with Steps 3 through 6.
STEP 3: Remove all tension COMPLETELY from remaining torsion spring. Use a
sturdy ladder and stand to the side of the winding bars and insert one winding
bar as shown in Illus. 1. Winding bars MUST always be inserted the full depth
of the holes in the winding cone and supported (be prepared to handle a
large force) before any set screws on the spring winding cones are loosened.
Positioning your hand near the end of the winding bar, push up on the winding
bar to allow the second winding bar to be inserted, then slowly allow the second
winding bar to rest against the back of the door, as shown in Illus. 2. Watch out
that your fingers do not get pinched between the winding bar and back of the
door or that the winding bar does not hit any window glass in the top section. If
you cannot push the first winding bar up or feel uncomfortable with the force on
the bar, stop, and contact a qualified door service professional.
STEP 4: Loosen the two set screws on the spring winding cone while firmly
holding the lower winding bar and making sure that the lower winding bar is
against the back of the door. When set screws are loose, full spring tension will
be on the lower winding bar. See Illus. 3.
STEP 5: Push up on the upper winding bar slightly and remove the lower winding
bar while holding tight on the upper winding bar. Allow the spring and upper winding bar to slowly rotate downward so that
the upper bar rests against the back of the door. This decreases the tension on the spring in 1/4 turn increments. See Illus. 4.
STEP 6: Repeat this process of inserting a winding bar fully in the upper hole position, push up slightly, removing the lower
winding bar and letting the tension slowly rotate the winding bar until it rests against the back of the door. Repeat this process
until all tension is removed from the torsion spring. There should be no tension on the cables, and the shaft should rotate
freely. Proceed to weigh the door.
