For Doors without Coupler Assembly:

Equalize the amount that the torsion shaft/torsion keyed shaft protrudes on each side. Align the stationary cone(s) of the torsion springs with the slots in the end bearing brackets and secure using (2) 3/8”-16 x 1-1/2” hex head bolts and nuts.

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 re-using the hex head screws, the lock wash- ers, the flat washers and the hex nuts, as shown.

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

Next, align the stationary cone(s) of the torsion springs with the slots in the center bearing brackets and secure using (2) 3/8”-16 x 1-1/2” hex head bolts and nuts. Repeat for opposite side. Secure all oval bearing(s), to the center bracket with (2) 3/8”-16 x 1-1/2” hex head bolts and (2) 3/8”-16 hex nuts. Insert bearing(s) into stationary cone and attach center bracket(s) to the torsion spring(s) using (2) 3/8”-16 x 1-1/2” bolts and (2) 3/8”-16 hex nuts. Repeat for others.

21	Counterbalance Lift Cables
	Tools: Locking pliers, 3/8” Wrench

IMPORTANT: RIGHT AND LEFT AND IS ALWAYS DETERMINED FROM INSIDE THE GARAGE LOOKING OUT.

Slide the black cable drum against the left hand end bearing bracket. Thread the counterbal- ance lift cable up and over the sheave and the black cable drum and position the cable drum and counterbalance lift cable, as shown. Hook the cable into the drum.

NOTE: For doors with a torsion keyed shaft, insert (1) key into the slot of both the black cable drum and the slot in the torsion keyed shaft, as shown.

Tighten the set screws in the black cable drum to 14-15 ft. lbs. of torque (once set screws contact the shaft, tighten screws one full turn). Slide the red cable drum against the right hand end bearing bracket.

Rotate the right hand drum and torsion shaft until counterbalance lift cable is taut. Apply locking pliers to track above third roller to prevent door movement and to keep counterbal- ance lift cables taut. Thread the counterbalance lift cable up and over the red cable drum and position the cable drum and counterbalance lift cable, as shown. Hook the cable into the drum.

NOTE: For doors with a torsion keyed shaft, insert (1) key shaft into the slot of both the red cable drum and the slot in the torsion keyed shaft, as shown.

Tighten the set screws in the red cable drum to 14-15 ft. lbs. of torque (once set screws contact the tube, tighten screws one full turn).

IMPORTANT: Check each counterbalance lift cable, making sure both are seated properly on the sheaves, cable drums, are securely attached to the bottom corner brackets and both sides have equal counterbalance lift tension.

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 perforated angle of the rear back hangs to keep counterbalance lift cable taut. Repeat the same process for right hand side.

Now, secure the coupler assembly by tightening the (3) hex head screws and the (3) hex nuts.
