Installation (Fig. 55)
1. If isolator and wire cables were removed from cable
bracket (item 10), insert cables into isolator. Secure iso-
lator and cables to bracket with isolator bracket and
washer head screw. Torque screw from 90 to 110 in- -lb
(10.2 to 12.4 N- -m).
2. Apply antiseize lubricant to the splines of the trans-
axle and traction motor shafts.
CAUTION
To prevent motor damage and personal injury,
make sure that traction motor is well supported
as it is installed. Motor weighs approximately 66
pounds (30 kg).
3. Wrap suitable lifting strap around traction motor
housing for support and as a lowering point for motor in-
stallation. Do not capture encoder (speed sensor) or
thermistor wires under strap.
4. Carefully lower traction motor into vehicle. Align mo-
tor shaft with transaxle input shaft and slide motor to
transaxle. Take care to not damage encoder (speed
sensor) while installing motor.
5. Secure traction motor to transaxle:
A. Align mounting holes of motor and transaxle.
B. Install four (4) flange head screws (item 9)
through transaxle holes and into traction motor leav-
ing upper two (2) holes vacant for cable bracket in-
stallation.
C. Position cable bracket with attached cables to
motor and transaxle. Install final two (2) flange head
screws.
D. Torque all six (6) flange head screws from 90 to
110 in- -lb (10.2 to 12.4 N- -m) to secure motor to
transaxle.
E. Remove lifting strap from traction motor.
Electrical System
6. Make sure motor terminals and cables are clean (no
corrosion) and in good condition.
IMPORTANT: When connecting cables to motor ter-
minals (U, V and W), use a wrench to retain lower nut
while tightening upper nut (Fig. 56). If terminal studs
are allowed to turn during upper nut installation, in-
ternal motor damage can occur.
7. Using labels placed during motor removal, secure
electrical connections to traction motor:
A. Plug connectors from traction motor traction mo-
tor encoder (speed sensor) and thermistor (tempera-
ture) into vehicle wire harness.
B. Make sure that lower nuts are installed on motor
terminals and are torqued from 72 to 88 in- -lb (8 to 9
N- -m).
C. Install correct cable, lock washer and nut to motor
terminals U, V and W. While retaining lower nut,
torque upper nut from 72 to 88 in- -lb (8 to 9 N- -m).
8. Connect the conductors between the battery pack
and vehicle components (see Opening Battery Circuit in
the General Information section of this chapter). Make
sure to torque hex nuts on battery terminals from 72 to
88 in- -lb (8 to 9 N- -m).
9. After all cable connections are made, apply Toro bat-
tery terminal protector (see Special Tools) to all battery
posts and traction motor cable connectors to prevent
corrosion. Make sure that cable terminal boots are posi-
tioned over all connections.
10.Install cargo bed to the vehicle (see Cargo Bed
Installation in Service and Repairs section of Chapter 5
-- Chassis).
11. Before returning vehicle to operation, fully charge
the batteries by connecting the on--board battery char-
ger to an appropriate electrical outlet.
