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 938H continues to use powershift
transmission technology proven on
previous series. The countershaft
powershift transmission features heavyduty 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 938H 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.

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 938H features a durable
plate engine frame and two 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 938H 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, lift cylinders and tilt cylinder.
The fabricated, two-plate loader tower
design reduces material packing under
the lift cylinders while absorbing the
forces associated with loading, twisting
and material handling.
Counterweight. The two-piece
counterweight is integrated into the
938H design and provides added
protection for the lights by incorporating
them into the top of the structure.
Linkage. The 938H linkage is a singletilt Z-bar design. Z-bar linkage generates
excellent breakout force and good rack
back angle for better bucket loading
and load retention.
Lift arms are solid steel, providing
superior strength with an excellent front
end viewing area. The proven design
offers excellent dump clearance
and reach.

LOAD SENSING HYDRAULICS. The 938H
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
and a 16% increase in lift force.

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 938H
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, full-power 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.
AUTOLUBE. The optional Caterpillar
Autolube System provides precise,
automatic lubrication of pins and
bushings – during loader operation.
Automatic lubrication reduces time spent
on daily maintenance and downtime for
unplanned repairs due to inadequate
greasing – improving productivity.
