20	Torsion Spring Assembly
	Tools Required: 3/8” Wrench, 9/16” Wrench, Step Ladder

NOTE: Refer to the Package Contents and or Parts Breakdown to determine if your door came with a coupler assembly.

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

IMPORTANT: 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.

IMPORTANT: On single spring applications, only a left hand wound (black winding cone), which goes on the RIGHT HAND SIDE is required.

NOTE: The set screws used on all torsion winding cones and cable drums are now colored red. DO NOT identify right and left hand by the set screw color.

If you don’t have a Coupler Assembly:

Facing the inside of the door, lay the torsion shaft / torsion keyed shaft on the floor. Lay the

the torsion keyed shaft. Next on the right hand side, lay the other coupler half, center bearing, the torsion spring with the black winding cone, and the black cable drum at the right end of the torsion keyed shaft.

Slide the coupler halves, center bearings onto the torsion keyed shafts followed by the torsion springs and the cable drums, as shown.

IMPORTANT: The coupler halves, center bearings, torsion springs, cable drums must be positioned, as shown.

Slide the flat edge of the couple half flush with the side edge of the torsion keyed shaft. Insert

(1)key into the slot of both the coupler half 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.

NOTE: Tighten the set screws to 14-15 ft. lbs. of torque (once set screws contact the shaft, tighten set screws one full turn). Repeat the same process for the other coupler half.

Slide the center bracket bearing / center bracket bushing onto the torsion shaft / torsion keyed shaft followed by the torsion springs and cable drums.

IMPORTANT: The center bracket bearing / center bracket bushing, torsion springs, and cable drums must be positioned, as shown.

With assistance, pick up the torsion 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 bearing bracket. Position the torsion shaft / torsion keyed shaft so that equal amounts of the shaft extend from each end bearing bracket.

If you have 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. Set the components aside. Facing the inside of the door, lay the (2) torsion keyed shafts on the floor. One torsion keyed shaft on the left hand side and the other torsion keyed shaft on the right hand side. Starting on the left hand side, lay one of the coupler halves, the center bearing, torsion spring with the red winding cone and the red cable drum at the left end of

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 end bearing brackets.
