4. Lubricate new O-rings with dielectric lubricant and install the O-rings into the
grooves in the motor cover. Place the wave washer in the cover bearing bore
and fit the rotor assembly into the cover.
5. Secure the base plate of the motor rotor tool to the housing with four M6 –
1.0 X 50 cap screws.
6. Install the rotor tool shaft into the base plate and turn it in so the end of the
shaft prevents the rotor body from entering the housing assembly.
The rotor magnets are very powerful and can cause the rotor to shift
position very rapidly during installation. Be cautious during rotor
installation to prevent component damage or personal injury.
7. While supporting the rotor and cover assembly, slowly turn the rotor tool
shaft to allow the rotor to be drawn into the housing assembly. Once the
rotor and cover assembly is fully seated in the housing, remove the rotor
tool base plate.
8. Secure the cover to the housing with the six cap screws and tighten the
screws from 8 to 9 N·m (70 to 80 in−lb).
9. Make sure that rotor rotates without binding before installing the motor
assembly.
Refer to Figure 106 for this procedure.
1. If previously removed, install the square key and spur gear on the motor shaft.
A. Apply medium strength thread locking compound (Loctite 243 or
equivalent) to the socket head cap screw (item 9) and tighten the screw
to 15 N·m (11 ft-lb).
B. Apply medium strength thread locking compound (Loctite 243 or
equivalent) to the set screw (item 7) and tighten the set screw.
2. Use a new O-ring and new gasket and fit the 3WD traction motor to the
gear box cover.
3. Install the fasteners securing the motor to the cover and tighten the fasteners
from 11 to 12 N·m (8 to 9 ft-lb).
4. Assemble and install the 3WD gear box assembly; refer to
Box (Optional 3WD) (page
5. If the 3WD traction motor was replaced, update the machine software;
