9. Install the rotor tool shaft into the base plate and turn it in against the rotor
shaft.
CAUTION
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.
10. 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.
11. Remove the motor cover and wave washer from the rotor assembly.
12. Remove and discard the O-rings from the motor cover.
13. Remove and discard the O-ring from the motor housing.
14. If necessary, remove and discard the bearings from the output gear and rotor.
15. Inspect the cutting unit motor components for wear or damage. Replace
components or complete cutting unit motor assembly if necessary.
Assembling the Cutting Unit Motor
Refer to
or this procedure.
1. Make sure that motor components are cleaned before assembly.
2. If the bearings were removed from the rotor or the output gear, install new
bearings. Make sure the new bearings are fully pressed onto rotor or output
gear shaft.
3. Lubricate a new O-ring with dielectric lubricant and install it into the groove
in the housing bearing bore.
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.
