Hydraulic
system has built-in reliability and provides exceptional
lift, breakout and auxiliary power to work tools.
|

Maximum
power and reliability are built into the Cat Skid
Steer Loader hydraulic system. In addition to providing
power to drive the wheels, this system also provides
the loader lift and tilt functions, powers the auxiliary
circuit to drive work tools and drives the engine
cooling fan.

The
hydraulic pumps are driven directly off the engine
for maximum hydraulic performance and reliability
- no belts are used. Pumps are fixed-displacement
and provide flow to the loader and auxiliary circuits
at 60 L/min (15.6 gal/min) at high idle. Maximum
system pressure for the loader and auxiliary circuit
is 21 400 kPa and 3110 psi.

| · |
Standard
auxiliary hydraulics to power work tools is available
through quick connect hydraulic couplings that are
rigidly mounted to the loader arm. The Caterpillar
line of high pressure XT ES hoses and O-ring
face seals help assure a leak-free system.

Hydraulic
system reliability and cleanliness are improved
by using single components in place of multiple
components, such as the monoblock hydraulic valve
and monoblock pumps. Fewer leak points improve reliability
and result in a cleaner machine.
In
addition, hydraulic oil flows through a 5-micron,
spin-on filter. A filter restriction indicator
is located in the operator station. A 74-micron
screen in the hydraulic tank prevents larger debris
from entering the system and causing damage to
the hydraulic components.

A
high-efficiency, hydraulic oil cooler lets the Cat
Skid Steer Loader work longer and harder in higher
ambient temperatures, even when using continuous
high flow work tools. The high capacity, hydraulic
oil reservoir also helps keep operating temperatures
lower.

World-class
operator station provides exceptional working comfort
with excellent visibility, enhanced fingertip control
and optimum instrumentation.

Caterpillar
hystat power train delivers aggressive performance
and easy operation.
