7.
Apply Loctite 638 (Green) to the shaft of
the motor.
8.
Install the sprocket (in the correct
orientation as observed in step 2 above)
on the motor shaft.
9.
Apply Loctite 222 (Pink) to the set screw
and tighten the Allen set screw.
10.
Plug the IDC connector into the Motor
Termination PCB (refer to drawing
134868 page 2 wiring diagram).
11.
Place the motor assembly down into
position on the circular section of the
feed assembly and slide forward under
the mounting screw heads.
12.
Use your 3mm Allen wrench to re-engage
motor, ensuring that the teeth on the
drive sprocket mesh with the sprocket in
the circular section of the feed. Tighten
the motor mounting screws.

Circular Limit Switch Replacement Procedure:
The feed assembly does not need to be re-calibrated as long as the potentiometer has not been replaced,
disengaged or removed from its mounting location.
After you have ascertained that the circular section potentiometer is failed:
1.
Note orientation of the failed limit
switch.
2.
From the underside of the bracket, using
your 2mm Allen wrench, remove the
mounting screws and remove the failed
limit switch.
3.
Install the replacement switch on the
bracket using the screws removed in the
previous step. This should orient the
body of the switch such that the wire
connections will be outward from the
body of the feed assembly.
4.
If the wires will be soldered to the
replacement switch, unsolder the wires
from the failed switch. Install a short
piece of heat shrink tubing on each wire
and then solder each wire to the correct
terminal on the switch (refer to drawing
134868 page 2 wiring diagram).
5.
If the wires and heat shrink are already
provided on the replacement switch,
disconnect the wires of the failed switch
and punch the wires of the replacement
switch into the IDC connector that plugs
into the Motor Termination PCB (refer to
drawing 134868 page 2 wiring diagram).
6.
Plug the IDC connector into the Motor
Termination PCB (refer to drawing
134868 page 2 wiring diagram).
