4.1 DRIVE MOTORS

The electric wheel drive assemblies are mounted indepen-
dent of each other on the base frame at the rear of the
machine.
The wheel drive assembly consists of a 15V AC asynchro-
nous electric motor driving a gear box. The assembly also
includes a friction disk parking brake assembly. This
brake assembly is mounted on the end of the drive motor
assembly.
The component parts of the left and right drive motor
assemblies are identical.

Brake - Dust Cleaning

Due to a possible build-up of dust from brake lining wear
inside the brake compartment, it is recommended to per-
form this dust cleaning task on an annual basis using
clean, oil free, compressed air.
Figure 4-1. Dust Cleaning
1. Disconnect battery plug.
2. Remove chassis hoods.
3. Remove the dust protection ring (1) from the friction
plate retaining groove (2) and pull it over the magnet
body (3).
4. Blow any accumulated dust in brake compartment.
5. Once complete, correctly reposition the dust protec-
tion ring.

Brake Disassembly

Figure 4-2. Brake Disassembly
1. Place the machine on a flat and level surface. Using
ground controls fully rotate the turntable either to the
left or to the right. Turn power off and disconnect
battery plug. Chock both front wheels.
2. Remove chassis hoods. Remove chassis rear shield.
3. Disconnect electric cables from brake terminal block
(1).
4. Remove dust protection ring (2) from friction plate
retaining groove (3) and pull it over magnet body (4)
as shown. The protection ring will help to keep all
parts together during brake removal.
5. Loosen the 3 screws (5) securing brake assembly.
6. Remove magnet body and armature plate assembly
(6).
7. Remove brake disk (7) from driver (8). Remove fric-
tion plate (3).

Brake Disk Wear Checking

Figure 4-3. Brake Disk Wear Checking
Check brake disk thickness on several locations.
Replace the disk if its thickness is below 8.5mm (0.335
in.).
