Hydraulic System Oil - Change
Clean the oil cooler and clean the radiator at the
same time. Clean the oil cooler in the same manner
as you clean the radiator.
You can use compressed air, high pressure water,
or steam to remove dust and other debris from the
radiator core. However, the use of compressed air
is preferred.
Note: Care must be taken when you are using high
pressure water. High pressure water can cause
damage to the radiator. Use of a water spray nozzle
on the pressure washer which will disperse the water
pressure is preferred.
Note: Cat HYDO Advanced 10 has a 50% increase
in the standard oil drain interval for machine
hydraulic systems (3000 hours versus 2000
hours) over second and third choice oils - when
following the maintenance interval schedule for
oil filter changes and for oil sampling that is
stated in the Operation and Maintenance Manual
for your particular machine. 6000 hour oil drain
intervals are possible when using S·O·S Services
oil analysis. Contact your Cat dealer for details.
Note: At the same interval, clean the air conditioner
condenser.

NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to
collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.
Hydraulic tank drain valve (1) is located on the bottom
of the hydraulic tank in front of the right tractor wheel.
Refer to Special Publication, NENG2500, “Caterpillar
Dealer Service Tool Catalog” for tools and supplies
suitable to collect and contain fluids on Caterpillar
products.
• The parking brake must be applied.
Dispose of all fluids according to local regulations and
mandates.
Note: The normal hydraulic oil change interval
is at every 2000 Service Hours or 1 Year. By
performing S·O·S oil analysis, the hydraulic
oil change interval may be extended to 4000
Service Hours or 2 Years. S·O·S oil analysis
must be performed at every 500 Service Hours
or 3 Months in order to extend the hydraulic oil
change interval. The results from the S·O·S oil
analysis will determine if the hydraulic oil change
interval may be extended. If S·O·S oil analysis is
not available, the hydraulic oil change interval
must remain at every 2000 Service Hours or 1
Year . Refer to the Operation and Maintenance
Manual, “S·O·S Information”.
Note: Before you change the hydraulic tank oil, the
machine must meet the following conditions:
• The machine must be level.
• The hydraulic oil must be warm.
• The transmission control must be in NEUTRAL.
• The bowl must be lowered.
