Loosen the adjustment nut of the Torque Limiter located on the top
of the Gear Box on the GS6000 sufficiently to allow the large drive
sprocket and output shaft to turn without back driving the gear box,
v-belt and motor (see exploded view at back of this manual, the
Torque Limiter adjustment nut is the top component of Part No.
010217). This is done by first loosening the small set screws
(5/64” hex key required) on the adjustment nut facings and then
loosening the nut (1-5/8” hex socket or wrench).
At this time also loosen the Stop Pall that is mounted to the large
output drive sprocket (see Figure 9 below), this requires a 1/8” hex
key tool.
Attach the Crank Arm to the Output Shaft by fitting the arm’s large
circular opening onto the shaft, see Figure 10, Action A. Slide the
crank arm onto the operator’s output shaft such that the slot on the
arm is roughly parallel with the closed gate. The crank arm should
be pointing towards the bracket on the gate.
Turn the output shaft so that the hole to mount the clevis pin is
lined up with the hole in the crank arm. Insert the clevis pin fully
through the hole in the crank arm, the hole in the output shaft and
extend through the other side of the crank arm, see Figure 10,
Action B. The ring on the clevis pin should be on the gate side of
the crank arm when fully inserted.
At this time insert the release handle/bolt assembly into the outer
through hole on the crank arm, see Figure 10, Action C. The
release handle/bolt assembly is inserted such that it points away
from the gate. Place the 3/8 internal tooth lock washer onto the
bolt end and screw on the 3/8 wing nut finger tight, see Figure 10,
Action D. As you are tightening the wing nut hold the handle such
that it is pointing away from the crank arm. Tighten the wing nut
as tight as possible with finger pressure.
Rotate the release handle 180 degrees such that it is parallel and
pointing in the same direction as the crank arm, see Figure 10,
Action E. This action completes the installation of the crank arm
to the output shaft. Ensure the arm is tight on the shaft.
As shown in Figure 8, attach the Crank Arm Extension to the
Crank Arm with the (2) 1/4-20 x 1-1/2” long bolts, (4) 1/4 internal
tooth lock washers, and (2) 1/4-20 keps washer hex nuts, (Items 9
through 13) provided. For a standard installation use the two holes
