Grooming Reel Bearing Replacement

Bearing Removal
1. Park machine on a clean, level surface. Lower cut-
ting units completely to the ground, stop engine, engage
parking brake and remove key from the ignition switch.
2. Disconnect the cutting units from the electrical power
supply by separating the cutting unit power disconnect
couplers (see Opening Electrical Circuit to Cutting Units
in the General Information section of this chapter). This
will prevent unexpected cutting unit operation.
3. Remove the cutting unit from the machine and place
cutting unit on a flat work area.
4. To remove groomer drive plate assembly from right
side of cutting unit, remove front roller, grooming reel
and then drive plate assembly (see Grooming Reel (For-
ward Rotating or Counter Rotating) in this section).
5. To remove support plate assembly from left side of
cutting unit (Fig. 19):
A. Remove two (2) socket head screws and lock
nuts that secure motor mount to cutting unit (Fig. 19).
Remove motor mount from cutting unit.
B. Remove lock nut and spring washer that secure
LH groomer arm lift rod to support plate (Fig. 20). Re-
move support plate from cutting unit.
6. Remove grooming reel seals and bearings from RH
drive plate and LH support plate assemblies (Figs. 21,
22 and 23). Discard all removed seals and bearings.
Bearing Installation
1. Install new grooming reel bearings and seals into RH
drive plate and LH support plate assemblies (Fig. 24):
IMPORTANT: Bearings should be installed with ex-
tended inner races toward center of housing. Also,
apply pressure equally to inner and outer bearing
races when installing bearings.
A. Press new outer bearing fully to shoulder of RH
drive plate bore. Then, install new inner bearing until
inner race contacts outer bearing race.
B. Press new bearing into LH support plate until it is
flush with shoulder of bearing bore.
C. Install new seals into groomer side plates. NOTE:
Seals should be installed so the lip side of the seal
will face the center of the cutting reel. When bearings
are greased, grease will purge from inner seals.
