Counterbalance Lift Cables

Tools Required: Step ladder, Locking pliers, 3/8” Wrench, Tape measure, Safety

glasses, Leather gloves

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).

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 CABLE MAKING SURE THEY ARE

SEATED PROPERLY ONTO THE CABLE DRUMS AND THAT BOTH COUNTERBALANCE LIFT

CABLES HAVE EQUAL TENSION.
Once the counterbalance cables are set and if applicable tighten the coupler assembly

together by tightening the (3) 3/8” - 16 nylon hex lock nuts to secure the coupler halves

together.

Chalking Torsion Spring(s)

Tools Required: Step ladder, Chalk, Safety glasses, Leather gloves

Draw a chalk line horizontally along the center of the torsion spring coil(s). As the torsion

spring is wound, the chalk line will create a spiral. This spiral can be used to count and

determine the number of turns that are applied on the torsion spring.

Securing Door for Spring Winding

Tools Required: Vice clamps, Safety glasses, Leather gloves

With the door in the fully closed position, place vice clamps / c-clamps onto both vertical

tracks just above the third track roller. This is to prevent the garage door from rising while

winding springs.

NOTE:

Check the following before attempting to wind torsion spring(s):

a. Counterbalance lift cables are secured at bottom corner brackets.
b. Counterbalance lift cables are routed unobstructed to cable drums.
c. Counterbalance lift cables are correctly installed and wound onto cable lift drums.
d. Counterbalance lift cables are taut and have equal tension on both sides.
e. Cable lift drums are against end bearing brackets and set screws are tight.
f. Torsion spring or springs are installed correctly.
g. Review the label attached to the spring warning tag, to determine number of spring turns

required.

NOTE:

Door MUST be closed and locked when winding or making any adjustments to the

torsion spring(s).

WARNING

FAILURE TO ENSURE DOOR IS IN A CLOSED POSITION AND TO PLACE

VICE CLAMP ONTO VERTICAL TRACK CAN ALLOW DOOR TO RAISE AND

CAUSE SEVERE OR FATAL INJURY.
