5. Remove the 6 torx-head screws that secure the motor cover (item 8 in
119) to the rear of the motor housing.
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. Use an electric motor rotor tool set (refer to
(page 5–16)) to carefully remove the rotor assembly (items 11, 5, and 12 in
Figure 119) and motor cover from the motor housing.
7. Remove the motor cover and wave washer from the rotor assembly. Remove
and discard the O-rings (items 10 and 7 in
8. Remove and discard the O-ring (item 3 in
Ensure that you do not damage the gearbox cover counterbore when
removing the shaft seal from the cover.
9. Carefully remove the shaft seal from the gearbox cover, and discard the seal.
10. If necessary, remove the bearings from the output gear (item 14 in
119) and rotor. Discard the bearings if they are removed.
11. Inspect grease in the output gear area of the motor housing. If grease is
clean and not contaminated, it can remain in the housing. If grease is
contaminated, clean the grease from the housing and replace with 15 ml of
NLGI grade 00 grease during motor assembly.
12. Inspect the motor components for wear or damage. Replace the components
or complete electric motor assembly if necessary.
1. Ensure that all the motor components are cleaned before assembly.
2. If the bearings were removed from the output gear (item 14 in
and rotor, install new bearings.
Note: Ensure that the bearings are fully pressed onto the shafts.
3. Lubricate new inner O-ring (item 3 in

the motor housing.
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.
4. Use an electric motor rotor tool set (refer to
(page 5–16)) to carefully install the rotor assembly (items 11, 5, and 12 in
