2. If machine is equipped with optional Turf Guardian
Leak Detector System, remove leak detector tank and
solenoid valve assembly (see Leak Detector Tank (Ma-
chines Equipped with Optional Turf Guardian
Detector System) and Leak Detector Solenoid Valve As-
sembly (Machines Equipped with Optional Turf Guar-
TM
dian Leak Detector System) in this section).
3. Remove four (4) cap screws (item 7), flat washers
(item 9), neoprene washers (item 8) and spacers (item
20) that secure tank cover to hydraulic reservoir.
4. Loosen hose clamp and disconnect overflow hose
(item 10) from tank cover barb.
NOTE: On Greensmaster 3320 machines with serial
number above 312000000, the fuel system carbon can-
ister is attached to the reservoir cover. See Fuel System
Carbon Canister (Serial Number Above 312000000) in
the Service and Repairs section of Chapter 3 -- Gasoline
for information on disconnecting the canister.
5. Remove tank cover from machine.
6. Completely drain hydraulic oil from hydraulic reser-
voir through gear pump suction hose into a suitable con-
tainer.
7. Label hydraulic reservoir hydraulic hoses for assem-
bly purposes. Thoroughly clean hydraulic hose ends
prior to disconnecting the hoses from hydraulic reservoir
fittings.
8. Remove hose assemblies and O--rings from hydrau-
lic reservoir fittings. Allow hoses to drain into a suitable
container.
9. Put clean caps or plugs on disconnected hoses and
fittings to prevent contamination.
10.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).
11. Remove four (4) cap screws (item 14), flat washers
(item 13) and flange bushings (item 12) that secure the
hydraulic reservoir (item 3) to the tank mount plate.
12.Remove hydraulic reservoir from machine.
13.If hydraulic fittings are to be removed from reservoir,
mark fitting orientation to allow correct assembly. Re-
move hydraulic fittings and plugs from hydraulic reser-
voir as needed. Discard O--rings from removed fittings
and plugs.
14.Clean hydraulic reservoir and reservoir components
with clean solvent. Inspect reservoir for leaks, cracks or
other damage.

Leak
Threads in reservoir may become damaged.
1. Lubricate and place new O--rings onto all removed
fittings and plugs. Install fittings and plugs into reservoir
openings. Use marks made during the removal process
to correctly orientate fittings. Refer to Figure 59 for res-
ervoir fitting and plug installation torque specifications.
2. Position hydraulic reservoir onto the tank mount
plate.
3. Apply antiseize lubricant to threads of four (4) cap
screws (item 14). Secure hydraulic reservoir to the tank
mount plate with four (4) cap screws, flat washers (item
13) and flange bushings (item 12). Torque cap screws
from 30 to 50 in- -lb (3.4 to 5.6 N- -m).
4. 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).
5. Remove caps and plugs from disconnected hydrau-
lic hoses and reservoir fittings.
6. 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).
7. If machine is equipped with optional Turf Guardian
Leak Detector System, install leak detector tank and so-
lenoid valve assembly (see Leak Detector Tank (Ma-
chines Equipped with Optional Turf Guardian
Detector System) and Leak Detector Solenoid Valve As-
sembly (Machines Equipped with Optional Turf Guar-
TM
dian Leak Detector System) in this section).
NOTE: On Greensmaster machines with serial number
above 312000000, see Fuel System Carbon Canister
(Serial Number Above 312000000) in the Service and
Repairs section of Chapter 3 -- Gasoline for information
on connecting the fuel system carbon canister.
8. Position tank cover to top of hydraulic reservoir.
9. Connect overflow hose (item 10) to tank cover barb
and secure with hose clamp.
10.Apply antiseize lubricant to threads of four (4) cap
screws (item 7). Secure tank cover to hydraulic reservoir
with four (4) spacers (item 20), cap screws (item 7), flat
washers (item 9) and neoprene washers (item 8).
Torque cap screws from 30 to 50 in- -lb (3.4 to 5.6 N- -m).
11. Fill hydraulic reservoir with new hydraulic oil.
