1. Electric motor housing
2. Motor rotor tool base plate
4. Secure the base plate of the motor rotor tool (Toro part number 139-8420) to
the housing with four M6 – 1.0 X 50 cap screws.
5. Install the rotor tool shaft into the base plate and turn it in against the rotor
shaft.
The rotor magnets are very powerful and can cause the rotor to
shift position very rapidly during removal. Be cautious during rotor
removal to prevent component damage or personal injury.
6. Turn the rotor tool shaft to push the rotor and cover assembly from the
housing assembly. Support the rotor to prevent it from falling during removal.
7. Remove the motor cover and wave washer from the rotor assembly.
8. Remove and discard the O-rings from the motor cover.
9. Remove and discard the O-ring from the motor housing.
10. If necessary, remove and discard the bearings from the rotor.
11. Inspect the electric motor components for wear or damage. Replace
components or complete electric motor assembly if necessary.
Refer to Figure 68 for this procedure.
1. Make sure that motor components are cleaned before assembly.
2. If the bearings were removed from the rotor, install new bearings. Make sure
the new bearings are fully pressed onto the rotor shaft.
3. Lubricate a new O-ring with dielectric lubricant and install it into the groove
in the housing bearing bore.
