STEP 4 – Removing the Existing Door
Springs
Garage doors use springs to balance the door weight. There
are two types of springs used — extension and torsion. Each
of these is available in either a standard or EZ-Set
TM
assembly
option. Please look at the drawings on page 8 to see which
springs your old door has installed. If your present door uses
standard torsion springs, do not attempt to remove the
door or the springs yourself. They should be removed by
a qualied door service professional. Attempting to remove a
torsion spring assembly without proper training and tools may
result in an uncontrolled release of spring forces which can
cause serious or fatal injury.
Extension springs and EZ-Set
TM
Springs are shown on a
sectional garage door in the illustration on page 8 to see which
springs your door has. The following instructions detail how to
remove these springs.
Serious injury could result if spring tension has not been
released before other work begins.
Removing Extension Springs
Use two or more helpers to assist you in lowering
the door.
Step 4-1a: Raise the door to the full open position. Place “C”
clamps or locking pliers tightly on both sides of the track under
the door so the door is held securely in place. With the door
fully open, most spring tension has been removed. (FIG. 4-A)
Do not attempt to remove or adjust extension springs with door
in the down position. Use “C” clamps to keep the door from
moving or falling once the springs are removed.
Step 4-2: Detach the cable at both ends. Disassemble and
remove the springs and cable completely from the door.
NOTE: Wood blocks should be placed underneath the door
when closing to prevent ngers from being trapped.
Step 4-3: Remove the “C” clamps from the track and carefully
close the door.
Some large doors might weigh as much as 500 pounds when
the spring tension is removed. The weight of the door will not
be apparent when you rst begin to close the door. The door
will feel progressively heavier as it is lowered until its full weight
(as much as 500 pounds) is realized about one foot from the
oor. A single car door may weigh as much as 200 pounds.
(FIG. 4-B)
To avoid injury, keep hands and ngers clear of section
joints, track, and other door parts while the door is
opening and closing.

Step 4-1b: With the door in the DOWN position, position a
drill with a 7/16” socket bit over the worm drive. Using the
reverse (counter-clockwise) direction on the drill, remove all
the tension from the spring (repeat for each side). After spring
tension has been removed, detach the lift cables at both ends.
Disassemble and remove the springs and cable completely
from the door. (FIG. 4-C)
