Removing Hydraulic Reservoir (Fig. 78)
1. Park machine on a level surface, set brake, lower
cutting units and stop engine. Remove key from the igni-
tion switch.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components in
this section.
2. Disconnect oil level sensor wire connector from ma-
chine wire harness.
3. Remove leak detector tank (see Leak Detector Tank
Removal in this section).
4. Remove leak detector solenoid valve assembly from
hydraulic reservoir (see Leak Detector Solenoid Valve
Assembly in this section).
5. Completely drain hydraulic oil from hydraulic reser-
voir through gear pump inlet (suction) hose into a suit-
able container.
6. Label hydraulic reservoir hoses for assembly pur-
poses. Thoroughly clean hydraulic hose ends prior to
disconnecting the hoses from reservoir fittings.
7. Remove hose assemblies and O−rings from reser-
voir fittings. Allow hoses to drain into suitable container.
8. Put clean caps or plugs on disconnected hoses and
fittings to prevent contamination.
9. To allow easier access to fasteners that secure hy-
draulic reservoir, raise and support tank mount plate as-
sembly (hydraulic reservoir, fuel tank and tank mount
plate) (see Tank Mount Plate Assembly in the Service
and Repairs section of Chapter 7 − Chassis).
10.Remove four (4) cap screws (item 17), flat washers
(item 16) and flange bushings (item 15) that secure the
hydraulic reservoir (item 2) to the tank mount plate.
11.Remove hydraulic reservoir from machine.
12.If hydraulic fittings are to be removed from reservoir,
mark fitting orientation to allow correct assembly. Re-
move hydraulic fittings from hydraulic reservoir as need-
ed. Discard O−rings from removed fittings.
13.Remove oil level sensor (item 11) from hydraulic res-
ervoir. Discard O−ring from sensor.
14.Clean hydraulic reservoir and reservoir components
with clean solvent. Inspect reservoir for leaks, cracks or
other damage.
Installing Hydraulic Reservoir (Fig. 78)
1. Lubricate and place new O−rings onto all removed
fittings. Install fittings into reservoir openings. Use
marks made during the removal process to correctly
orientate fittings. Refer to Figure 78 for reservoir fitting
installation torque specifications.
2. Install oil level sensor into reservoir making sure that
arrow on sensor is pointing down (Fig. 79). Torque sen-
sor nut from 110 to 140 in−lb (12.5 to 15.8 N−m).
3. Position hydraulic reservoir onto tank mount plate.
4. Apply antiseize lubricant to threads of four (4) cap
screws (item 17). Secure hydraulic reservoir to the tank
mount plate with four (4) cap screws, flat washers (item
16) and flange bushings (item 15). Torque cap screws
from 30 to 50 in−lb (3.4 to 5.6 N−m).
5. Lower and secure tank mount plate assembly (hy-
draulic reservoir, fuel tank and tank mount plate) (see
Tank Mount Plate Assembly in the Service and Repairs
section of Chapter 7 − Chassis).
6. Remove caps and plugs from disconnected hydrau-
lic hoses and reservoir fittings.
7. Lubricate and position new O−rings to fittings on res-
ervoir. Use labels placed during the removal process to
properly install hydraulic lines to reservoir fittings (see
Hydraulic Hose and Tube Installation in the General In-
formation section of this chapter).
8. Install leak detector solenoid valve assembly to hy-
draulic reservoir (see Leak Detector Solenoid Valve As-
sembly in this section).
9. Install leak detector tank (see Leak Detector Tank
Installation in this section).
10.Connect oil level sensor wire connector to machine
wire harness.
11.Fill hydraulic reservoir with new hydraulic oil.
12.Verify leak detector operation.
