NOTE: If you just installed the
Torquemaster ® Plus counterbalance,
continue with Step 4 on page 12. If you
have the Torquemaster
® counterbalance
system, complete Steps 2-3 on pages 10
and 11.
Shake the torque tube gently to extend the
winding shafts out about 5" on each side.
For single spring applications, there will be
no left hand spring in the torque tube.
Lift the torque tube and rest it on the top of
the flagangles. Orient torque tube so that
back of opener is flat against header/
mounting surface.
NOTE: Cable drums and torque tube are
cam shaped to fit together only one way.
Pre-wrap the Torquemaster ® cable drum
with the counter balance cable 1/2 wrap
(see illustrations).
To install the cable drum, slide the cable
drum over the winding shaft until the cable
drum seats against the torque tube. The
winding shaft must extend past the cable
drum far enough to expose the splines and
the groove.
Align the winding shaft groove with
the round notch in the flagangle.
For double spring applications, repeat for
opposite side.
For single spring applications, pre-wrap the
left hand Torquemaster
® cable drum with
counter balance cable 1/2 wrap and insert
loose winding shaft into the cable drum
prior to sliding the cable drum over the
torque tube.
NOTE: On single spring applications, take
care in handling the loose winding shaft
(left side) so that it does not slide back into
the torque tube.
Beginning with the right hand side, lubricate
entire circumference of the drive gear
with lubricating oil. Slide the drive gear onto
the winding shaft splines until it touches
the flagangle.
NOTE: On single spring applications,
no drive gear is required on the left side.
NOTE: If additional lubricating oil is
required “Dura-Lube Engine Oil Treatment”
is recommended.
