Removing Hydraulic Reservoir (Fig. 80)
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. Remove four (4) cap screws (item 7), flat washers
(item 9), neoprene washers (item 8) and spacers (item
20) that secure reservoir cover to hydraulic reservoir.
3. Loosen hose clamp and disconnect overflow hose
(item 10) from reservoir cover barb.
NOTE: On Greensmaster 3300 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.
4. Remove reservoir cover from machine.
5. Completely drain hydraulic oil from reservoir through
gear pump suction hose into a suitable container.
6. Label reservoir hydraulic hoses for assembly pur-
poses. Thoroughly clean hydraulic hose ends prior to
disconnecting hoses from hydraulic reservoir fittings.
7. Remove hydraulic hoses and O--rings from hydraulic
reservoir fittings. Drain hoses into a 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 14), flat washers
(item 13) and flange bushings (item 12) that secure the
hydraulic reservoir (item 3) to the tank mount plate.
11. Remove hydraulic reservoir from machine.
12.If reservoir fittings are to be removed, mark fitting ori-
entation to allow correct assembly. Remove hydraulic
fittings and plugs from hydraulic reservoir as needed.
Discard O--rings from removed fittings and plugs.

13.Clean hydraulic reservoir and reservoir components
with clean solvent. Inspect reservoir for leaks, cracks or
other damage.
Installing Hydraulic Reservoir (Fig. 80)
IMPORTANT: When installing reservoir cover and
reservoir to machine, do not over- -tighten cap
screws. Threads in reservoir may become dam-
aged.
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 80 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).
NOTE: On Greensmaster 3300 machines with serial
number above 312000000, see Fuel System Carbon
Canister (Serial Number Above 312000000) in the Ser-
vice and Repairs section of Chapter 3 -- Gasoline for in-
formation on connecting the fuel system carbon
canister.
7. Position reservoir cover to top of hydraulic reservoir.
8. Connect overflow hose (item 10) to reservoir cover
barb and secure with hose clamp.
9. Apply antiseize lubricant to threads of four (4) cap
screws (item 7). Secure reservoir cover to hydraulic res-
ervoir 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).
10.Fill hydraulic reservoir with new hydraulic oil.
