Service and Repairs
Hydraulic Reel Motor
IMPORTANT: When performing maintenance pro-
cedures on the cutting units, carefully position the
cutting unit reel motors to prevent damage to the
motors or hydraulic hoses.
Removal
1. Park machine on a clean and level surface, lower
cutting units completely to the ground, stop engine, en-
gage parking brake and remove key from the ignition
switch.
2. Loosen two (2) flange nuts that secure the hydraulic
reel motor to the cutting unit side plate. Rotate motor
clockwise and remove motor from cutting unit.
3. Inspect cutting reel insert splines for wear. Replace
inserts if necessary (see Reel Removal and Installation
in the Service and Repairs section of this chapter).
4. Inspect the O--ring on the reel motor flange and re-
place O--ring if damaged.
5. Place protective plastic cap (see Special Tools) into
the hole in the cutting unit side plate to prevent debris
entry into reel bearing area.
Installation
NOTE: Refer to Figure 12 for correct placement of cut-
ting unit reel motors and weights.
1. Coat spline shaft of the reel motor with No. 2 multi-
purpose lithium base grease. Lubricate the O--ring on
the motor flange with clean oil.
2. Rotate the motor clockwise so the motor flanges
clear the flange nuts in the cutting unit side plates. Align
reel motor shaft splines with cutting reel insert splines.
Slide motor shaft into reel insert.
3. Rotate the motor counter--clockwise until the motor
flanges are encircling the cap screws in the side plates.
While holding motor, tighten two (2) flange nuts to se-
cure reel motor to cutting unit.
IMPORTANT: After installing cutting reel motor,
make sure that the reel motor hoses are not twisted,
kinked or in the risk of being pinched.
