six cylinder engine. The C6.6 utilizes
ACERT Technology, a series of
Caterpillar engineered innovations that
provides advanced electronic control,
precise fuel delivery and refined air
management, resulting in outstanding
performance and lower emissions.
The C6.6 with ACERT Technology
offers a compact design with big, heavy
duty engine features for outstanding
durability, reliability and performance.
The C6.6 incorporates a new cross flow
cylinder head design, 4 valve head and
an ADEM™ A4 electronic controller.
The C6.6 also features a proven cylinder
block, pistons and crankshaft.
Electronic Control ADEM™ A4.
The Advanced Diesel Engine
Management – Electronic Control
Module consistently monitors important
engine conditions and functions. It uses
sensors throughout the engine to regulate
fuel delivery and all other engine systems
that require input to manage load and
performance. The ADEM A4 controller
is the brain behind engine responsiveness,
self-diagnosis, controlling emissions
and fuel economy.
Air Management. Air management
is a key concept in optimizing engine
performance and controlling emissions.
Engines must breathe clean cool air in
order to perform. To aid this, the C6.6
uses a turbocharger fitted with a smart
waste gate to give precise and reliable
control of the boost pressure. A new
cross-flow design in the cylinder head
facilitates air movement, while tighter
tolerances between the piston and
cylinder wall reduce blow by gases.
Fuel System. Through multiple injection
fuel delivery, fuel is introduced in the
combustion chamber in a number
of precisely controlled microbursts.
Injecting fuel in this way allows for
precise shaping of the combustion cycle
while reducing engine sound levels
Fuel Pump. The C6.6 uses an oillubricated high-pressure fuel pump
to feed a common fuel rail. By using
an oil-lubricated fuel pump, the C6.6
has been designed to be more tolerant
of alternative fuels.
Fuel Priming Pump. An electrical fuel
priming pump is located between the fuel
tank and the combined water separator/
primary fuel filter. The electric priming
pump eliminates the need to pre-fill or
manually prime filters after a change,
thus reducing contamination and
improving injector life.
Engine Idle Management. The Engine
Idle Management System (EIMS)
maximizes fuel efficiency and provides
flexibility in managing idle speeds
for specific application requirements.
Four idle control speeds are available.
Powershift Transmission. The IT38H
continues to use powershift transmission
technology proven on previous series.
The countershaft powershift transmission
features heavy-duty components to
handle the toughest applications.
Built-in electronic controls enhance
productivity and durability.
Control Throttle Shifting. Control Throttle
Shifting regulates engine speed during
high-energy directional and gear changes
for smoother shifting and longer
component life.
Electronic Clutch Pressure Control.
Electronic Clutch Pressure Control
(ECPC) system modulates clutches
individually to improve shift quality,
component life and operator comfort.
Adjustment is simplified with all
solenoid valves externally mounted
on top of the transmission housing.
Axles. The IT38H axles are designed by
Caterpillar for durability in all operating
conditions. The front axle is rigidly
mounted to the frame to support the
weight of the wheel loader and withstand
internal torque loads as well as external
forces encountered throughout operation.
The rear axle is designed to allow
±12° oscillation. All four wheels remain
on the ground over uneven terrain
providing excellent stability
and traction.

Built Strong and Tough
Durability
Page 7
Integrated Braking System. The Cat
exclusive Integrated Braking System
reduces axle oil temperatures and
improves transmission neutralizer
smoothness. IBS has a direct impact
on durability of the axles and brakes
especially in applications involving
long distances and/or heavy braking.
Radiator. Brazed aluminum construction
provides a stronger joint for maximum
durability and resistance to leaks.
The 6-fins-per-inch design decreases
the chance of blockage and plugging.
Structures. The articulated frame design
of the IT38H features a durable plate
engine frame and four plate loader
tower that is robotically welded.
Robotic welding creates frame joints
with deep plate penetration welds and
excellent fusion for maximum strength
and durability.
Engine End Frame (EEF). The IT38H
uses a proven solid plate engine end
frame which provides a strong, rigid
structure that resists twisting and evenly
distributes impact loads. The result is an
extremely solid mounting platform for
the engine, transmission, axle, ROPS
and other accessories.
Hitch. The distance between the upper
and lower hitch plates is an important
contributor to machine performance and
component life. The Caterpillar hitch
design provides excellent load distribution
and bearing life. Both the upper and
lower hitch pins pivot on double tapered
roller bearings – improving durability
by distributing both vertical and
horizontal loads over a larger surface
area. The wide opening also provides
excellent service access.
Non-Engine End Frame (NEEF).
The non-engine end frame provides a
solid mounting base for the front axle,
lift arms and lift cylinders. The fabricated,
four-plate loader tower absorbs the
forces associated with loading, twisting
and material handling.
Counterweight. The one-piece
counterweight is integrated into the
IT38H design and provides added
protection for the lights by incorporating
them into the top of the structure.
8-Bar Linkage. This linkage provides
parallel lift to keep the load level
throughout the lift cycle – particularly
important when using forks. Parallel lift
allows the operator to concentrate on
placing the load, instead of retaining it.
Visibility to the work tool is excellent.

• Hydraulics are easy to control with
low effort
• Differential locks provide maximum
traction in varying underfoot
conditions
• Constant net horsepower across
various applications
• Standard and optional features that
maximize productivity
Load Sensing Hydraulics. The IT38H
features a load sensing hydraulic system
that supplies flow and pressure for the
implements only upon demand, and
only in the amounts necessary to
perform the needed work thus providing
a more efficient loader.
With the new S3PC Priority Proportional
Pressure Compensation Valve, implement
control is improved over the previous
system – raise/lower and rack back/dump
can be operated simultaneously.
Operators will notice enhanced ease
of operation, more rimpull into the pile
as well as an increase in lift force.
New! Differential Lock. Maximize
productivity with the new hydraulic
locking front differential. This standard
feature provides operators with the
confidence to maneuver through poor
underfoot conditions with ‘on the fly’
engagement.
A Caterpillar exclusive, the optional
automatic front/rear locking differential
collects input from sensors throughout
the loader and adapts tractive effort to
meet operating requirements.
Constant Net Horsepower. On many
competitive machines, gross horsepower
is constant, meaning that net engine
power available for actual work will vary
based on demands made from parasitic
sources, such as air conditioning or
cooling fans.
The Cat C6.6 engine is electronically
configured to provide constant net
horsepower at full parasitic load
enhancing productivity and improving
fuel efficiency.
On-Demand Fan. With electronic control
of the variable speed on-demand fan,
temperature levels of the engine
coolant, transmission oil, hydraulic oil
and air inlet manifold are constantly
monitored. This data is used to control
and maintain fan speed at the level
necessary to maintain normal system
temperatures. Controlled fan speed
improves fuel efficiency, lowers noise
levels and reduces radiator plugging.
Isolated Cooling System. The IT38H
cooling system is isolated from the
engine compartment by a non-metallic
shield. The hydraulically driven,
variable speed fan draws in clean
air from the rear of the machine and
exhausts it out the sides and top of
the hood. The end results are optimal
cooling efficiency, increased fuel
efficiency, less radiator plugging
and reduced operator sound levels.
Countershaft Powershift Transmission.
The electronic countershaft powershift
transmission with automatic shift
capability is designed and built by
Caterpillar. The very responsive, fullpower speed and directional changes
provide excellent cycle times
and productivity.
Fuel Economy Mode. Match transmission
shifting patterns to machine application
requirements. The Fuel Economy Mode
(within Messenger) provides operators
with the ability to choose between three
different shift modes in order to maximize
shift quality and fuel efficiency.
Ride Control. The optional Ride Control
System improves ride, performance and
load retention when traveling over rough
terrain. Operators gain confidence
moving at higher speeds in load and
carry operations decreasing cycle times
and increasing productivity.
