Upper Drive Chain Removal
Pry off the edge guard (26). Remove the 4 screws secur-
ing the chain guard (22) and insert guard (25) that are
in line with the 4 holes in the motor mount arm. Pull the
chain guard out towards the motor mount arm. Slowly
run the feeder until the chain-connecting link is acces-
sible in the space between the tire and the upper motor
guards. Turn off and unplug the feeder. Pry off the con-
necting link C-clip and remove the link. Pull the chain
away from the motor sprocket and remove.
Reassemble in the reverse order noting the following:
The 2 legs of the chain will straddle the single stand off
that is directly between the 2 sprockets. Loosening the
4 bolts that attach the motor may ease fitting the
new connecting link. The C-clip should be placed so
the open end faces away from the direction of travel
(counter-clockwise rotation).
Lower Drive Chain Removal
Remove the 2 screws securing the insert guard (25),
the 5 screws securing the chain guard (22) and the 4
screws securing the lower motor guard (27). Slowly run
the feeder until the chain-connecting link is accessible
in the space between the tire and the frame. Turn off
and unplug the feeder. Pry off the connecting link C-clip
and remove the link.
Reassemble in the reverse order noting the following:
Loosen the 4 bolts that attach the motor and rotate it
clockwise. Temporarily retighten one of the top bolts
until the chain is fitted and then rotate the motor back
until the chain is taut. Retighten the motor bolts. The
C-clip should be placed so the open end faces away
from the direction of travel (clockwise rotation).
Motor Drive Sprocket Removal
Remove the drive chain. Loosen the 2 set screws that
secure the sprocket. Pull off the sprocket and key.
Reassemble in the reverse order noting the following:
Locate the sprocket with the hub facing outwards and
the inside face of the sprocket about 1/4" from the
upper motor guard or lower motor mounting plate.
Upper Motor Removal
Unplug the upper motor. Remove the upper drive chain.
Remove the 4 bolts attaching the upper motor while
supporting the motor. Remove the motor (28), motor
guard (21), short standoffs (15), second motor guard
(21), long standoffs (20) and the bolts.
Reassemble in the reverse order.
Lower Motor Removal
Remove the lower drive chain. Remove the 4 bolts
attaching the motor (28) and pull out the motor. Remove
the 4 screws attaching the motor electrical box (41) and
pull off the box. Pull off the red and black motor leads
from the rectifier. Remove the screw (47), nut (48) and
lock washer (49) securing the ground wires.

6810-22 Ultra Cable Feeder
Reassemble in the reverse order noting the following:
The lock washer is placed against the electrical box.
Before attaching the electrical box, make sure the motor
is oriented properly. Inserting the motor mount screw
through the frame hole first will make aligning the 3
other screws easier.
Rectifier Removal
Remove the 4 screws attaching the motor electrical
box (41) and pull off the box. Remove the 4 leads to the
rectifier. Remove the screw (61) and nut (62) attaching
the rectifier (46).
Reassemble in the reverse order noting the following:
On the upper motor the black wire connects to the posi-
tive terminal of the rectifier and the red wire connects
diagonally opposite. On the lower motor, the red wire
connects to the positive terminal of the rectifier and the
black wire diagonally opposite. The positive terminal of
the rectifier is the one 90° different that the other 3.
The blue and brown wires are interchangeable on the
remaining 2 terminals.
Control Unit Removal
Unplug the upper motor. Remove the lower motor elec-
trical box as described in rectifier removal. Unplug the
blue and brown wires from the rectifier and disconnect
the ground wires. Remove the 6 screws securing the
control unit. Pull out the top of the control unit. Remove
the 2 black wires from the emergency stop switch by
loosening the set screws and pulling out the wires.
Remove the control unit.
Reassemble in the reverse order.
(If replacing individual components of the control unit,
pay close attention to the proper wiring shown in the
electrical diagrams, especially the polarity of the low
voltage connections at the relay.)
Main Electrical Box Removal
Remove the control unit. (The wires to the lower motor
can be disconnected at the control unit instead of at
the lower motor to save effort.) Unscrew the nut attach-
ing the flexible conduit to the electrical box and pull
the conduit away. Pull out the electrical box while lifting
it up and keeping it square to the frame. Pull off the
contact assembly from the emergency stop switch.
Unscrew the lock nut and remove the switch.
Reassemble in the reverse order.
Upper Traction Wheel Removal
Remove the upper drive unit from the feeder. Remove
the 3 screws that attach the bearing retainer (16) to the
arm (3). Remove the 2 bolts securing the arm to the
cross bar (14). Pull the arm off the axle bearing and
rotate it out of the way. Remove the 4 flat head screws
attaching the wheel and lift off the wheel.
Reassemble in the reverse order.
