Drive Motors

How to Remove a Drive Motor
The drive motors are AC powered and are a
brushless design requiring very little maintenance.
They have built-in speed and temperature sensors
which is monitored by the ground controls (GCON).
The speed sensor is a Hall-effect type and is part of
the rear motor shaft bearing. The temperature
switch will shut down the drive motor if it becomes
excessively hot.
1 Disconnect the battery pack from the machine.
Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
2 Chock both sides of the wheels at the steer
end of the machine.
3 Center a lifting jack under the drive chassis at
the non-steer end of the machine.
4 Loosen the wheel lug nuts. Do not remove
them.
5 Raise the machine approximately 2 inches / 5
cm. Place blocks under the chassis for
support.
Crushing hazard. The chassis
will fall if not properly supported.
6 Remove the wheel lug bolts. Remove the tire
and wheel assembly.
