Hydraulic System Oil - Change
SMCS Code: 5056-044
NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before open-
ing any compartment or disassembling any compo-
nent containing fluids.
Refer to Special Publication, NENG2500, “Caterpillar
Tools and Shop Products Guide” for tools and supplies
suitable to collect and contain fluids on Caterpillar
products.
Dispose of all fluids according to local regulations and
mandates.
1. Operate the machine in order to warm the
hydraulic oil.
2. Park the machine on level ground. Lower the
attachment to the ground and apply slight
downward pressure. Engage the parking brake
and stop the engine.

Illustration 204
3. The hydraulic tank is located on the right side of
the machine. Press the button on the breaker
relief valve (1) in order to relieve any tank
pressure.
4. Remove the hydraulic tank filler cap (2) and the
filler strainer (3). Wash the filler cap and the
strainer in a clean, nonflammable solvent. Install
the strainer.
5. Inspect the gasket on the hydraulic tank filler cap
for damage. Replace the gasket, if necessary.
6. Remove the drain plug (5) from the bottom of the
hydraulic tank. Wash the drain plug in a clean,
nonflammable solvent.
7. The hydraulic tank is equipped with an ecology
drain valve. Attach a hose to a 126-7914 Oil
Drain Coupling. Install the threaded end of the
coupling into the drain valve in order to unseat
the internal drain valve.
NOTICE
Never start the engine while the hydraulic oil tank is
being drained or while the hydraulic oil tank is empty.
Excessive wear and damage to the hydraulic compo-
nents can occur.
8. Close the drain valve. Install the drain plug.
9. Change the hydraulic oil filter.
Reference: Refer to Operation and Maintenance
Manual, “Hydraulic System Oil Filter - Replace”
for the correct procedure.
10. Fill the hydraulic tank with clean oil. Make sure
that the oil level is at the “FULL” mark on the
sight gauge (4). Install the filler cap.
Reference: Refer to Operation and Maintenance
Manual, “Lubricant Viscosities and Refill
Capacities” for the correct type of oil and for the
correct amount of oil.
11. Start the engine and run the engine for at least
ten seconds. Then, stop the engine and add
hydraulic oil to the tank until the oil level is at
the “FULL” mark on the sight gauge. Install the
filler cap.
12. Start the engine and run the engine at low
idle. Cycle the implements so that all hydraulic
systems are filled with oil.
Note: If the alert indicator for a low oil level comes
on, stop the engine and immediately add oil to the
hydraulic tank. The oil level should not be below the
suction ports in the hydraulic tank while the engine
is running.
13. Add hydraulic oil to the tank until the oil level is
at the “FULL” mark on the sight gauge.
14. Stop the engine. Top off the hydraulic tank so
that the oil level is at the “FULL” mark on the
sight gauge. Install the filler cap.
