If you don’t have a Coupler Assembly:

Slide the center bracket bushing into the center bracket. Align the stationary spring cone(s) with the holes in the center bracket bushing assembly. Secure the torsion spring(s) to the center bracket bushing assembly with (2) 3/8”-16 x 1-1/2” hex head bolts and (2) 3/8”-16 nuts.

IMPORTANT: The spring warning tag(s) supplied must be securely attached to the stationary spring cone(s) in plain view. Should a replacement spring warning tag be required, contact Wayne-Dalton for free replacements.

If you have a Coupler Assembly:

Slide the center bearing into the center bracket. Align the stationary spring cone with the holes in the center bearing bracket. Secure the torsion spring to the center bracket with (2) 3/8”-16 x 1-1/2” hex head bolts and (2) 3/8”-16 nuts. Repeat the same process for the other center bearing bracket.

At the middle of the two center bearing brackets, re-assemble the coupler assembly by loosely fastening the coupler halves together using the (3) 3/8”-16 x 1-3/4” hex head screws and the (3) 3/8”-16 nylon hex lock nuts, as shown.

NOTE: Ensure both torsion keyed shafts have equal amounts of the shafts extending from each end bearing brackets.

19	Counterbalance Lift Cables
	Tools: Step Ladder, Locking Pliers, 3/8” Wrench

Starting on the left hand side, thread the counterbalance lift cable up and around the front side of the left hand cable drum.

IMPORTANT: Verify that there are no counterbalance lift cable obstructions.

Hook the counterbalance lift cable into the left hand cable drum. Slide the left hand cable drum up against the left hand end bearing bracket. Counterbalance lift cable should terminate at the 3 o’clock position. Tighten the (2) set screws in the drum to 14-15 ft. lbs. of torque (once set screws contact the shaft, tighten screws one full turn).

NOTE: If you have torsion keyed shaft(s), insert (1) key into the slot of both the cable drum and the slot in the torsion keyed shaft, as shown.

Rotate the left hand drum and torsion shaft until counterbalance lift cable is taut. Now attach locking pliers to the torsion shaft and brace locking pliers up against jamb to keep counter- balance lift cable taut.

Repeat for right hand side.

IMPORTANT: Inspect each counterbalance lift cables making sure they are seated properly onto the cable drums and that both counterbalance lift cables have equal tension.
