cable with the terminals is outside of the motor
shell. Turn the cable so that the orange and blue
wires are facing the field coils.
11. Push the cable in so that the outer jacket is flush
with the bottom of the strain relief. Reassemble
the strain relief to clamp the cable in place.
12. Using small butt splices and small shrink tubing,
connect the field wires (orange and blue) with the
appropriate marked wires coming from the field
coils.
13. Connect the armature wires (2 red and 2 black) to
the appropriately marked brush leads using the
large butt splices and shrink tubing.
14. Pull each of the 4 armature slices through the
access holes in the motor end cap.
15. Pull the brake leads (yellow and brown) through
the access hole in the motor end cap.
16. Install the connector for the brake onto the yellow
and brown leads. The leads can go with either of
the connector pins.
Reassembling the Motor
1. Install the armature through the motor shell and
into the separated end cap. Retain the armature in
the end cap with the retention bolt.
2. Using a small brush hook or similar tool, pull each
of the brush springs so that they are contacting
the back of the brushes and are pushing the brush
down on the commutator.
3. Push the end cap back into the motor shell. Line
up the marks made in the disassembly instruc-
tions. Install the end cap retaining bolt to hold the
parts together.
NOTE: Take care not to pinch any wires in the interface of
the end cap and motor shell. Cable access may need
to be pulled out of the strain relief to get the parts
assembled.
4. Reassemble the strain relief onto the cable.
5. Reassemble the motor to the gearbox per assem-
bly instructions shown in the motor and brake dis-
assembly in this section.
6. After both motors are serviced, jack up the drive
wheels of the scissor lift and drive the wheels
under no load for approximately 10 minutes to
seat the brushes, if the brushes have been
replaced.
