ACERT™ TECHNOLOGY. Since March
2003, ACERT Technology has been
proving itself in on-highway trucks.
More recently it has proven itself again
in field tests of off-highway equipment.
This technology allows Cat engines to
meet durability and reliability
expectations without sacrificing fuel
economy or performance.
CATERPILLAR DESIGNED
COMPONENTS. Components used to
build Cat Wheel Loaders are designed
and manufactured to Caterpillar quality
standards to ensure maximum
performance even in extreme operating
conditions.
Engine electronic control modules and
sensors are completely sealed against
moisture and dust. Deutsche connectors
and electrical wire braiding ensure that
electrical connections resist corrosion
and premature wear.
Hoses are engineered and manufactured
for high resistance to abrasion, excellent
flexibility and easy installation and
replacement.
Caterpillar
®
couplings use o-ring face
seals to provide positive sealing for
durable leak-free connections.
Heavy duty components reduce the risk
of leaks, corrosion and premature wear
increasing uptime and helping to protect
the environment.
MONITORING PROGRAMS. Monitoring
product health is key to maintaining
reliability of any equipment. Many
programs are available on the 950H both as standard and optional features to help you track machine condition.
Caterpillar Monitoring System. The
950H is equipped with the Cat
Monitoring System (CMS) that keeps
watch over the health of your loader.
CMS monitors critical engine system
functions and will derate the engine to
protect itself from damage if needed.
Depending on which of the following
six critical conditions arise, the CMS
monitor or front panel will display
warning lights and sound audible
alarms.
• High coolant temperature
• High air inlet temperature
• Low engine oil pressure
• High fuel pressure
• Low fuel pressure
• Engine over-speed
Product Link. Product Link is a state-ofthe-art satellite technology based
product that provides two-way
information flow between machine onboard systems and the Caterpillar
network operations center. Multiple
types of information can be collected
and tracked - from machine location
and service meter hours, to health and
productivity information.

RELIABILITY
EquipmentManager. With a
subscription to EquipmentManager
through the Cat Dealer Storefront the
information collected through Product
Link can be transmitted to a computer.
With fast, easy-to-access machine
information, you can optimize asset
utilization, reduce security risks,
improve maintenance management and
implement before-failure repair
strategies. The result is more uptime,
lower operating costs and a higher
overall return on equipment investment.
S•O•SSMServices. Keep minor repairs
from becoming major ones and avoid
complete failures. By regularly taking
samples from the ports provided, your
Cat dealer tracks wear of components
and parts, oil performance, and oil
condition and uses that data to predict
wear-related problems before they
happen. Often a simple adjustment or
replacement of a part, based on S•O•S
reports, can keep a small problem from
turning into a major repair - allowing
your machine to be running when you
need it, not waiting in the shop for
service.
DEALER SUPPORT. The Caterpillar

EPA TIER III, EU STAGE III COMPLIANT
C7 ENGINE. ACERT Technology
combines proven systems with
innovative new technologies to
precisely deliver fuel to the combustion
chamber. It maintains engine
performance, efficiency and durability
while dramatically reducing emissions.
The Cat C7 with ACERT Technology is
a 7.2 L displacement, 6-cylinder,
electronically governed engine.
Electronic fuel injection is provided
through the well-proven Caterpillar
hydraulically actuated, electronically
controlled unit injection (HEUI) system.
A wastegate turbocharger, equipped
with a titanium wheel for improved
durability, combined with air-to-air
aftercooling (ATAAC) provides
consistent high horsepower with
increased altitude capability.
Electronic Controller. The engine is
governed by the ADEM™ A4 electronic
control module. The controller
continually adjusts engine output based
on load demand using a series of
sensors located on the machine and
engine.
Hydraulically Actuated Electronic Unit
Injectors (HEUI). The HEUI™ system has
been at work in Cat engines across the
product line with a proven track record
of consistent, durable, reliable
performance.
Engine Block and Pistons. The gray,
cast iron engine block is made of the
same material as the cylinder heads.
Wall diameters are thicker than in
previous designs while adjustments
have been made to reduce sound levels
and increase rigidity. One-piece all-steel
pistons are housed within a wet,
replaceable cast iron cylinder liner
constructed of high-strength, heattreated castings. Steel-forged
connecting rods are larger in diameter
and are connected to the crankshaft with
two bolts.
Cylinder Head. The cylinder head is a
one-piece design that incorporates
cross-flow design to facilitate air
movement. This allows the engine to
breathe cooler, cleaner air with less
effort.
RADIATOR. Brazed aluminum
construction provides a stronger joint
for maximum durability and resistance
to leaks. The 6-fins-per-inch, squarewave core design decreases the chance
of blockage and plugging.
POWERSHIFT TRANSMISSION. The
950H continues to use heavy-duty
powershift transmission technology
proven on previous models and
currently used up through the largest
wheel loader built by Caterpillar - the
994F.
The planetary powershift transmission
features heavy-duty components to
handle the toughest applications. Builtin electronic controls enhance shift
quality, productivity and durability.
Control Throttle Shifting. Control
Throttle Shifting regulates engine speed
during high-energy directional 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 950H 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 ± 13°
oscillation. All four wheels remain on
the ground over uneven terrain
providing excellent stability and
traction.

Built Strong And Tough
DURABILITY
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.
STRUCTURES. The articulated frame
design of the 950H features a durable
box-section engine frame and rigid
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). A full boxsection engine end frame with hitch
plates at the front end provides a strong,
rigid structure that resists twisting and
impact loads. The result is an extremely
solid mounting platform for the engine,
transmission, axle, ROPS and other
accessories.
Spread Hitch. The distance between the
upper and lower hitch plates is an
important contributor to machine
performance and component life. The
Caterpillar spread 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 cylinders.
The fabricated, four-plate loader tower
absorbs the forces associated with
loading, twisting and penetration.
Counterweight. The two-piece
counterweight is integrated into the
950H design and styling. This 1853 lb
(840 kg) counterweight incorporates the
rear lights into the top of the structure.
A heavy-duty counterweight, 3084 lb
(1399 kg), is optional for logging or
high-lift applications.
Linkage. The 950H 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 for exceptional matching to both
on- and off-highway trucks.
Rotary sensors, for the tilt lever and lift
circuit allow the operator to
electronically set detent positions from
the cab. A guard covers the sensor to
protect it from damage.

• Hydraulics are easy to control with
low effort
• Maximum fuel efficiency and
flexibility in idle speeds
• Consistent horsepower regardless of
conditions
• Standard and optional features that
maximize productivity
LOAD SENSING HYDRAULICS. The
950H features a load sensing hydraulic
system that automatically adjusts to
operating conditions to provide only the
hydraulic flow required by the
implement for improved fuel efficiency.
With the new M3PC Priority
Proportional Pressure Compensation
Valve, implement control is improved
over the previous system - raise/lower
and rack back/dump can be operated
simultaneously and fine modulation is
repeatable for improved productivity.
Operators will notice enhanced ease of
operation, more rimpull into the pile
and a 20% increase in lift force.
Electrohydraulic Implement Controls.
Electrohydraulic implement controls on
the 950H provide the operator with incab programmable kickouts to prevent
material spillage - improving
productivity. The implement control
console features an optional
Forward/Neutral/Reverse switch
allowing fast, easy directional changes
to reduce cycle times.
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 C7 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.
Separated Cooling System. Many
competitive loaders use cooling systems
that pull air in from the sides, through
the engine compartment and exhaust it
out the rear of the machine. The 950H
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.
PLANETARY POWERSHIFT
TRANSMISSION. The electronic
planetary 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.
VARIABLE SHIFT CONTROL. Match
transmission shifting patterns to
machine application requirements.
Variable Shift Control (VSC) improves
shift quality and fuel efficiency in
certain applications by allowing the
transmission to upshift at lower engine
RPMs.

Work Smart And Move More
PRODUCTIVITY
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.
PAYLOAD CONTROL SYSTEM. Scales,
designed specifically for Cat machines
allow on-the-go weighing of material in
the bucket. Operators load trucks more
accurately and efficiently. Loading
trucks right the first time equates to
quicker cycles for the operator and
more productivity and controllability
for your operation.
Payload Control is offered as a factoryinstalled option. Driver tickets and a
variety of reports can be printed with
the addition of the optional printer.
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.
AGGREGATE AUTODIG. Well-received
by both experienced and novice
operators, the optional Aggregate
Autodig automates the loading process.
Aggregate Autodig provides smoother
loading cycles, consistently full
payloads and eliminates tire spin - all
without touching the controls.
