a torqueMaster ® spring system can be
identified by the end brackets. for single
spring applications, the right hand end
bracket will always have a drive gear,
counter gear, counter cover, and a winding
bolt head. the left hand end bracket will
have no gears, counter cover, or winding
bolt head. the hole for the winding bolt
head will be plugged.
for double springs, both the right hand
and left hand end brackets will always
have a drive gear, counter gear, counter
cover and a winding bolt head.

step 1: If you have a black counter cover:
Place a mark on the drive gear tooth and an
adjacent mark on the right hand end bracket
(fig. 1). loosen the lock nut using a 7/16”
wrench and continue with step 2.
If you have a gray counter cover: loosen
the lock nut using a 7/16” wrench and
continue with step 2.
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) and count the
number of turns the mark on the drive
gear 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’-5” Door height = 15 turns
6’-6” Door height = 15 turns
6’-8” Door height = 15 1/2 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

step 3: Verify that spring tension has been
released by pulling the counterbalance
cable on the right hand cable drum away
from the header (fig. 3). If spring tension
has been released, the cable will be loose.
In addition, the torqueMaster ® Spring
tube should be free to rotate in either
direction.
