SECTION 9D. HYDRAULIC TANK
GENERAL
The hydraulic tank is mounted to the right of the opera-
tor’s seat. A plastic cover is mounted over the hydraulic
tank and used for mounting the control panel.
The tank is a single piece molded plastic tank with a
vented cap that serves as a breather. The tank should
require little service other than cleaning unless punc-
tured or otherwise accidentally damaged.
NOTE:
Hydraulic oil expands when hot. Do not check the
oil level when the hydraulic oil is hot. Always clean
the hydraulic tank before checking the oil level to
prevent contamination of the hydraulic system.
A dipstick type level indicator is used to check hydrau-
lic oil level. The oil level should be checked daily. The
oil level should never be below the low level mark or
more than 0.25 in (6.35 mm) above the high level.
Check the filler cap and breather frequently for clog-
ging, wear, and damage.
Check the hydraulic oil for water (noted by a cloudy or
milky appearance), air (noted by a foamy appearance),
visible contaminants, and rancid odor (indicating
excessive heat). The hydraulic oil should be drained
and flushed and the filter replaced after changing major
hydraulic components.
If water, air or contaminant are indicated, the entire
hydraulic system must be inspected for leaks, dam-
aged cap/breather, bad seals, and contaminated oil
supplies. Repair or replace components or oil supplies
as necessary.
The hydraulic tank holds 8 U.S. gallons (30.28 liters).
The control panel, seat, and seat pan must be removed
to remove the tank.
REMOVAL
NOTE:
If available, use a portable filtering unit when
draining the hydraulic oil. If a portable filter is not
available, the oil should be drained into a clean
container and filtered for use. If filtering is not
available, dispose of the hydraulic oil and fill the
tank with clean filtered oil.
1. Using a portable filtering unit, pump the hydraulic
oil into a suitable clean container. The tank holds
8 U.S. gallons (30.28 liters). If a filtering unit is not
available, remove the drain plug at the bottom of
the tank and drain the oil into a suitable container.
2. After draining, replace the hydraulic tank drain
plug.
NOTE:
The hydraulic tank is mounted to the seat pan.
The seat and seat pan must be removed to
remove the hydraulic tank. The fuel tank and
hydraulic tank are seated on looped frame brack-
ets for support.
3. Remove the seat pan mounting bolts, the fuel tank
mounting bolts, and the hydraulic tank mounting
bolts (Figure 9D-1).
4. Tag and disconnect the seat interlock switch con-
nector located underneath the seat.
5. Carefully remove the seat and seat pan.
6. Disconnect the negative battery cable from the
battery.
7. Remove the control panel from the hydraulic tank
cover and place to the side.
8. Tag and disconnect the hydraulic return hoses
and outlet hose. Immediately plug the hoses and
tank to prevent contamination of the hydraulic sys-
tem.
CAUTION
Do not overfill the hydraulic tank. Overfilling the tank
will result in oil leakage through the filler cap
breather.
CAUTION
A damaged filler cap or clogged breather can result
in an over-pressurized tank and damage to the
hydraulic components or leakage. Inspect the filler
cap and breather for wear, damage, or clogging.
CAUTION
Dispose of unwanted oil properly. Dumping oil in an
unsafe manner is illegal. Check with the local envi-
ronmental officials for information on dumping oil
properly.
