Removal Instructions for
TorqueMaster™ Single Spring System
A TorqueMaster™ Single spring system can be identified
by the end brackets. The right hand end bracket will have
a drive gear,counter gear, counter assembly, and a
winding bolt head. The left hand end bracket will have no
gears, counter assembly, or winding bolt head. The hole
for the winding bolt head will be plugged.

Step 1
Check for spring tension by pulling the counterbalance cable
on the right hand cable drum away from the header (Fig. 21). If there is no spring tension the cable will be loose. In
addition,the torque tube should be free to rotate in either
direction. If there is no spring tension, loosen the lock nut
1/4 turn (Fig. 2-2) and proceed to Step 3. If the counterbalance cable is still taut and the torque tube is difficult to rotate, that is an indication that spring tension still exists. Place
a mark on the drive gear tooth and an adjacent mark on the
right hand end bracket (Fig.2-2). Loosen the lock nut 1/4
turn using a 7/16” wrench.

Fig. 2-1

IMPORTANT!
Right and left hand is always determined from inside the
building looking out.

Step 2
Using an electric drill (High torque / gear reduced to 1300
rpm preferred) with a 7/16” hex head driver, unwind the right
hand winding bolt head counterclockwise (Fig. 2-3) and count
the number of turns the mark on the drivegear passes the
adjacent mark on the end bracket. Referencing the chart
below, by door height, stop unwinding the spring once the
counted turns have reached the listed number of turns.
6’-0” Door Height = 14 turns
6’-3” Door Height = 14 1/2 turns
6’-6” Door Height = 15 turns
6’-9” Door Height = 15 1/2 turns
7’-0” Door Height = 16 turns
7’-3” Door Height = 16 1/2 turns
7’-6” Door Height= 17 turns
7’-9” Door Height = 17 1/2 turns
8’-0” Door Height = 18 turns

CAUTION

DO NOT USE IMPACT GUN TO UNWIND SPRINGS.
IMPORTANT!
DO NOT reference the counter assembly when counting the
number of turns being unwound on the right hand spring, but
follow the instructions above.

Step 3
Using a flat head screwdriver, pry the counter gear and
counter assembly from theright hand end bracket (Fig. 2-4).
Discard the counter gear and counter assembly.

Step 4
Remove the upper 5/16” x 1-5/8” lag screw from the right
hand end bracket (Fig. 2-5). Attach locking pliers to the upper portion of the end bracket and hold the housing steady
while removing the lower 5/16” x 1-5/8” lag screw and #10 x
1/2” phillips head screw from the end bracket (Fig.2-6).

Holding the right hand end bracket steady with locking pliers, carefully pry the end bracket and drive gear off the winding shaft using a flat head screwdriver (Fig. 2-7).

CAUTION

THE WINDING SHAFT MAY ROTATE WHEN REMOVING THE
END BRACKET AND DRIVE GEAR.

Step 6
Repeat Step 4 for the left hand side. Holding the left hand
end bracket...
