Removal (Fig. 55)
1. Park vehicle on a level surface, turn key switch to
OFF, engage the parking brake and remove key from
the key switch.
2. To allow easier access to traction motor, remove car-
go bed from vehicle (see Cargo Bed in the Service and
Repairs section of Chapter 5 -- Chassis).
3. Make sure that vehicle battery charger IS NOT con-
nected to electrical outlet. Open the battery circuit by
disconnecting the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter).
NOTE: Label all traction motor electrical leads for as-
sembly purposes.
IMPORTANT: When removing cables from motor
terminals (U, V and W), use a wrench to retain lower
nut while loosening upper nut (Fig. 56). If terminal
studs are allowed to turn during upper nut removal,
internal motor damage can occur.
4. Disconnect electrical connectors from traction motor
and position them away from motor:
A. While retaining lower nut to prevent it from loos-
ening, remove upper nut, lock washer and cable con-
nector from traction motor terminal studs U, V and W.
B. Unplug wire harness connectors from traction
motor encoder (speed sensor) and thermistor (tem-
perature).
5. Position disconnected cables and wire harness
leads away from traction motor.
CAUTION
To prevent motor damage and personal injury,
make sure that traction motor is well supported
as it is removed. Motor weighs approximately 66
pounds (30 kg).
6. Wrap suitable lifting strap around center of traction
motor housing for support and as a lifting point for motor
removal. Do not capture encoder (speed sensor) or
thermistor wires under strap. Support motor with strap
to prevent it from moving.
7. Remove two (2) flange head screws (item 9) that se-
cure cable bracket (item 10) to transaxle and traction
motor. Position cable bracket with attached cables away
from motor and transaxle.
8. Remove remaining four (4) flange head screws (item
9) that secure motor to transaxle.

9. Pull motor away from transaxle until motor shaft is
disengaged from transaxle input shaft. Then, carefully
lift motor from vehicle taking care to not damage motor
sensors or vehicle components while motor is being re-
moved.
10.If necessary, remove washer head screw (item 11)
that secures isolator retainer and isolator to isolator
bracket. Separate isolator and motor cables from brack-
et.
