If your door came with a Center Bracket Bushing:
Slide the center bracket bushing into the center bracket. Align the stationary spring cone(s)
with the holes in the center bracket bushing assembly.
If your door came with a Center Bearing Bracket(s):
Slide the center bearing into the spring. Align the stationary spring cone with the holes in the
center bearing bracket.
Secure the torsion spring to the center bracket bushing assembly or the center bearing
bracket assembly with (2) 3/8”-16 x 1-1/2” hex head bolts and (2) 3/8”-16 nuts. Repeat for
others, if applicable.
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.
For Doors with a Coupler Assembly:
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.

Counterbalance Lift Cables

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. Starting on the left hand
side, slide the left hand cable drum onto the torsion shaft and up against the left hand end
bearing bracket. Counterbalance lift cable should provide a minimum of 1/2 pre-wrap on the
cable drum. Tighten the (2) set screws in the cable drum to 14-15 ft. lbs. of torque (once set
screws contact the shaft, tighten set screws one full turn).
NOTE: For doors with a torsion keyed shaft, insert (1) key shaft 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 against the jamb to keep counter-
balance lift cable taut. Repeat the same process for right hand side.
Now, secure the coupler assembly by tightening the (3) 3/8”-16 x 1-3/4” hex head screws
and the (3) 3/8”-16 hex nuts.
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.
