Torsion Spring Assembly
22
IMPORTANT:
RIGHT AND LEFT HAND IS ALWAYS DETERMINED FROM INSIDE THE BUILDING
LOOKING OUT.
NOTE:
Torsion spring assemblies can be of several configurations depending on your door
size and door weight.
IMPORTANT:
ON SINGLE SPRING APPLICATIONS, ONLY A LEFT HAND WOUND (BLACK
WINDING CONE), WHICH GOES ON THE RIGHT HAND SIDE IS REQUIRED.
NOTE:
Identify the torsion springs provided as either right hand wound (red winding cone),
which goes on the LEFT HAND SIDE or left hand wound (black winding cone), which goes on
the RIGHT HAND SIDE.
Facing the inside of the door and referencing the illustrations shown, lay the torsion shaft /
torsion keyed shaft(s) on the floor.
NOTE:
If your door came with (2) torsion keyed shafts, one torsion keyed shaft should be on
the left hand side of the floor and the other torsion keyed shaft should be on the right hand
side of the floor.
Lay the torsion spring(s) with the black winding cone and the black cable drum at the right
end of the torsion shaft / torsion keyed shaft(s). Lay the torsion spring(s) with the red winding
cone and the red cable drum at the left end of the torsion shaft / torsion keyed shaft(s).
NOTE:
The set screws used on all torsion winding cones and cable drums are colored red.
DO NOT identify right and left hand by the set screw color.
IF YOUR DOOR CAME WITH A COUPLER ASSEMBLY:
Disassemble the coupler assembly
by removing the (3) 3/8” - 16 x 1-3/4” hex head screws and the (3) 3/8” - 16 nylon hex
lock nuts from the coupler halves. Loosen the set screws. Slide the flat edge of the coupler
half flush with the side edge of the torsion keyed shaft. Insert (1) key into the slot of both
the coupler halves and the slot in the torsion keyed shaft. Tighten the (2) set screws and the
locking nut to secure the coupler half to the torsion keyed shaft, as shown. Repeat the same
processes for the other coupler half.
NOTE:
Tighten the set screws to 14 - 15 ft. lbs. of torque (once set screws contact the shaft,
tighten set screws one full turn).
IMPORTANT:
THE COUPLER HALVES, CENTER BEARING(S), TORSION SPRINGS, AND CABLE
DRUMS MUST BE POSITIONED, AS SHOWN IN THE ILLUSTRATIONS.

IF YOUR DOOR DOESN’T HAVE A COUPLER ASSEMBLY:
With assistance, pick up the tor-
sion spring assembly and slide one end of the torsion shaft / torsion keyed shaft through one
end bearing bracket. Lay the middle of the torsion shaft / torsion keyed shaft into the center
bracket. Slide the other end of the torsion shaft / torsion keyed shaft into the other end bear-
ing bracket. Position the torsion shaft / torsion keyed shaft so that equal amounts of the shaft
extend from each of the end bearing brackets.

IF YOUR DOOR HAS A COUPLER ASSEMBLY:
With assistance and starting on the left hand
side of door, pick up the left hand torsion spring assembly and slide one end of the torsion
keyed shaft through the end bearing bracket. Lay the other side of the torsion keyed shaft
into the center bracket. Repeat the same process for the right hand torsion spring assembly.
Position both torsion keyed shafts so that equal amounts of the shafts extend from each of
the end bearing brackets.
