Reassembling The Motor - JLG 1930ES Service Maintenance Manual

NOTE: Be sure cut the leads just below the splice to leave
as much cable as possible.
9. Remove the old cable from the motor shell.
10. Install the new motor cable into the motor shell
through the strain relief such that the end of the
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.

SECTION 3 - CHASSIS & SCISSOR ARMS

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 instructions.
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 assembly
instructions shown in the motor and brake disas-
sembly 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.
