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.

NOTE: Measure the diameter of your springs. If your spring diameter is 3-3/4”, the springs do not share center brackets. If your spring diameter is either 2” or 2-5/8”, then two springs will share the same center bracket, unless a coupler assembly is provided.

If you don’t have a Coupler Assembly:

Slide center bracket bushing into the spring. 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.

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.

If you have a Coupler Assembly:

Slide center bracket bushing into the spring. Align the stationary spring cone with the holes in the center 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 bracket.

23	Counterbalance Lift Cables
	Tools Required: 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.

NOTE: Always assemble the left hand cable and cable drum first to help maintain equal cable tension on both sides of the door.

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).
