TORSION SPRING
HOW TO REMOVE TENSION FROM REMAINING SPRINGS IN ORDER TO WEIGH DOOR
These instructions apply only for the purpose of removing tension from residential EZ-SET
®
torsion spring configurations
with standard radius (springs mounted to the front header of the garage). If the door has two EZ-SET
®
torsion springs and
only one is broken, always replace both springs.
TOOLS NEEDED: 3/8" medium-duty reversible drill
1/4" insert bit or 7/16" socket wrench
C-clamp or locking pliers
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.
STEP 3: If there are two springs, the remaining unbroken
spring must be unwound and replaced. Remove all tension
COMPLETELY from the torsion spring. DO NOT loosen any
set screws on the spring winding cones. Insert the 1/4" insert
bit in the drill and engage the bit or 7/16" socket wrench
on the drive shaft of the winding unit and rotate the drive
shaft counterclockwise to remove tension from the spring
(Illus. 1). NOTE: High drill RPMs may cause lubricant to come
out of the winding unit. All tension in the spring is removed
when the line (or description) on the spring is in a straight line.
There should be no tension on the torsion cables, and shaft
should rotate freely. Proceed to weigh the door.
