6. Use cutting reel motor rotor tool set (see Special
Tools in this chapter) to carefully remove rotor assembly
(items 5, 6 and 7) and motor cover (item 2) from motor
housing.
7. Remove motor cover and wave washer (item4) from
rotor assembly. Remove and discard O- rings (items 14
and 3) from cover.
8. Remove and discard O- ring (item 8) from motor
housing.
IMPORTANT: Make sure to not damage the gearbox
cover counter bore when removing t he shaft seal
from the cover.
9. Carefully remove shaftseal from gearbox cover.Dis-
card removed seal.
10.If necessary, remove bearings from output gear
(item11)androtor(item6). Discardbearingsifremoved.
11.Inspect grease in output gear area of motorhousing.
If grease is clean and not contaminated, it can remain in
housing. If grease is contaminated, clean grease from
housingand replacewith 15ml ofNLGI grade 00grease
during motor assembly.
12.Inspect cutting reel motor components for wear or
damage. Replace components or cutting unit motor as-
sembly if necessary.
Assembly (Fig. 95)
1. Make sure that motor components are cleaned be-
fore assembly.
2. If bearings were removed from output gear (item 11)
or rotor (item 6) install new bearings. Make sure that
bearings are fully pressed onto shafts.
3. Lubricate newinner O- ring (item 8)with dielectriclu-
bricant (see Special Tools in this chapter) and install O-
ring into groove in motor housing.
IMPORTANT: The rotor magnets are very powerful
andcan causethe rotorto shiftposition veryrapidly
during installation. Use cutting reel motor rotor tool
set (see Special Tools in this chapter) to remove ro-
tor. Be cautious during rotor installation to prevent
component damage or personal injury.
4. Use cutting reel motor rotor tool set (see Special
Tools in this chapter) to carefully install rotor assembly
(items 5, 6 and 7) into motor housing.
5. Lubricate new O- rings (items 14 and 3) with dielec-
tric lubricant (see Special Tools in this chapter) and
install O- rings to grooves in motor cover. Place wave
washer (item 4) in cover.
6. Carefully slide motor cover onto rotor until it contacts
motor housing. Secure cover with six (6) torx head
screws.
7. Make sure that rotor rotates without binding before
continuing with motor assembly.
8. Placewavewasher (item4)into housingbore forout-
put gear bearing.
9. Make sure that output gear area of motor housing
has clean grease remaining in housing. If grease was
cleaned from housing, install 15 ml of new NLGI grade
00 grease int o housing during motor assembly.
10.Slide output gear assembly (items 5, 11 and 7) into
front of housing. Make sure that output gear teeth mesh
with rotor gear.
11.Install shaft seal (item 13) into gearbox cover. Press
shaft seal into front cover until it is flush with the cover
surface. Shaft seal should have the seal lip toward the
inside of the motor (Fig. 96).
12.Lubricate new O - rings (items 8 and 10) with dielec-
tric lubricant (see Special Tools in this chapter) and
install O- rings to grooves in gearbox cover.
IMPORTANT: Make sure to not damage the shaft
seal when installing the gearbox cover.
13.Carefully slide gearbox cover onto output gear shaft
until it contacts motor housing. Secure cover with six (6)
torx head screws.
14.Torque all torx screws (item 1) on gearbox cover and
motor cover from 70to80in-lb(8to9N-m).
1. Output gear
2. Gearbox cover
3. Shaft seal
