EPA TIER III, EU STAGE III COMPLIANT
C11 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 C11 with ACERT Technology
is an 11.1 L displacement, 6-cylinder,
electronically governed engine.
Electronic fuel injection is provided
through the well-proven Caterpillar
mechanically actuated, electronically
controlled unit injection (MEUI) 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 an electronic control module
designated the A4:E4V2. The controller
continually adjusts engine output based
on load demand using a series of sensors
located on the machine and engine.

Mechanically Actuated Electronic Unit
Injectors (MEUI). The MEUI 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, heat-treated
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, square-wave
core design decreases the chance of
blockage and plugging.

POWERSHIFT TRANSMISSION. The 966H
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

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 966H 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.

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.

Built Strong And Tough

DURABILITY

STRUCTURES. The articulated frame

design of the 966H 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 one-piece
counterweight is integrated into the 966H
design and styling. This 2,517 lb (1142 kg)
counterweight incorporates the rear
lights into the top of the structure.

Linkage. The 966H 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.

the 966H 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 C11 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 966H cooling system is isolated
from the engine compartment by a non­metallic 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, full­power 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.

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 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.

FUEL EFFICIENCY. Many manufacturers
tout fuel consumption as one of the
determining factors for machine
acquisition, but fuel consumption is only
part of the story. Productivity must also
play a part in the decision. Even more
importantly, how fuel consumption and
productivity interact – fuel efficiency –
should be considered.

966H Fuel Efficiency. Customer testing
of the 966H is showing an improvement
in fuel efficiency over the 966G Series
II. This fuel savings is achieved through
the use of the Caterpillar proportional­flow load sensing hydraulic system,
Engine Idle Management System
software, Variable Shift Control
and ACERT Technology.

ACERT™ Technology Fuel Economy.

Based on Caterpillar testing, the fuel
economy of Cat engines with ACERT
Technology is 3 to 5 percent better than
current competing technologies. This
fuel economy is directly related to the
complete combustion of fuel due to
the integration between the electronic
control that monitors conditions, the
air management system that controls
air volume and the fuel injection system
that delivers just the right amount of
fuel as needed.

Free Wheel Stator Torque Converter
(FWSTC). The free wheel stator torque

converter improves power train
efficiency in load and carry operations
which contributes to the improved fuel
efficiency of the 966H.

ENGINE IDLE MANAGEMENT SYSTEM.

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.

Hibernate Mode. Idle speed drops after
a preset time to provide lower fuel
consumption, reduced sound levels
and lower emissions.

Work Mode. Adjust to working idle
speeds according to customer preference
and operating conditions.

Warm-Up Mode. Keep the engine at a
consistent temperature in cold conditions.

Low Voltage Mode. Prevent battery drain
due to high electrical loads from
attachments and accessories.

• Grouped service points and sight
gauges for easy daily maintenance

• Convenient access to engine
compartment for excellent
serviceability

• Swing-out grill and cooling cores for
easy cleaning

• Electronic systems to monitor
product health

HYDRAULIC SERVICE CENTER.

Transmission oil and hydraulic filters are
located in the Hydraulic Service Center,
behind the hinged, right-side access
ladder. The hydraulic oil tank can be
drained from this location using the
access port.

• Hydraulic filter change interval at
500 hours

• Transmission filter change interval
at 1,000 hours

ELECTRIC SERVICE CENTER. Batteries,
relay panel and an optional tool box are
conveniently located below the left-side
access platform. The engine shutdown
switch is housed with the relay panel.
A compartment integrated into the access
platform contains the hood tilt actuation
switch, master switch and jump-start
receptacle.

GROUND LEVEL GREASE POINTS.

Grease fittings are grouped on the right
side of the machine in two convenient
locations – in a service compartment just
below the right-side service platform, and
a bank located just off the non-engine end
frame. These locations facilitate easy
lubrication of vital components located
throughout the machine.

AUTOLUBE. Reduce time spent on daily
maintenance and downtime for unplanned
repairs due to inadequate greasing with
the optional Caterpillar Automatic
Lubrication System. Precise lubrication
of pins and bushings at specific intervals
improves component wear and reduces
ground contamination from excessive
greasing.

S•O•S SERVICES. Sampling valves on
the 966H allow quick access to engine,
transmission and hydraulic oils for S•O•S
analysis. Oil change intervals and other
services can be optimized according to
your work schedule, reducing downtime
and managing expenses.

REMOTE PRESSURE TAPS. Pressure taps
for the steering and hydraulic systems,
transmission (optional) and brakes are
grouped behind an access panel just
below the right-side service platform.

BRAKE WEAR INDICATORS. Axles are
equipped with standard brake wear
indicators, allowing a technician to easily
determine when it is necessary to service
the brakes.

SIGHT GAUGES. Well-protected, yet easily
visible sight gauges for the transmission,
hydraulic oil and radiator coolant allow
easy daily checks while reducing the risk
of contaminants entering the systems.

Easy To Maintain – Easy To Service

SERVICEABILITY

ENGINE COMPARTMENT ACCESS.

The non-metallic hood on the 966H
has been redesigned and restyled from
previous models. Side and top panels are
stronger due to more robust reinforcement
ribs – the change in contour also adds to
rigidity of the hood.

A single mechanical lift cylinder
with manual back-up opens the hood.
The tilting hood provides excellent access
to the engine compartment, and if
necessary, the entire hood can be
removed with the built-in lift points.

With the hood closed, quick checks of
engine oil levels and the coolant sight
gauge can be completed through the
side service doors.

Panels located behind the tires lift up
and can be removed for additional access.
Roading fenders hinge from the rear and
swing out allowing easier access to the
engine compartment.

ECOLOGY DRAINS. Engine, transmission
and hydraulic oils can be easily drained
with standard-equipment ecology drains.
An axle oil ecology drain is optional.

ELECTRIC PRIMING PUMP. An electric
fuel priming pump located on the primary
fuel filter base eliminates the need to
pre-fill or manually prime filters after
a change, eliminating engine
contamination.

COOLING SYSTEM. Cooling system
access for clean-out and maintenance
is outstanding. The perforated and
corrugated grill minimizes debris build­up and swings out for easy cleaning and
access to the cooling cores.

The full-width air conditioning condenser
and oil cooler cores swing out 45° to
allow easy cleaning of the rear radiator
face. Access panels on either side of the
radiator support structure provide access
to the front face of the radiator and
ATAAC cores for easy cleaning.

CAB. The entire operator station can be
removed in about 45 minutes and is easy
to re-attach. Quick disconnects are used
so no wires need to be cut and no
refrigerant is lost.

Cab cleaning is made easy with channels
on the cab floor and no threshold at the
door – the floor can be swept or mopped
out easily.

WINDSHIELD CLEANING PACKAGE.

An optional windshield cleaning package
consists of two steps for the loader front
frame, two additional handrails and a
folding mirror. This package allows
access to the entire front windshield
for easy cleaning.

COMPLETE CUSTOMER SUPPORT.

Cat field service technicians have the
experience and tools necessary to service
your loader on site. Technical experts at
the dealership and Caterpillar can provide
additional assistance to field service
technicians as needed.

When on-site repair isn’t enough, Cat
dealerships are fully equipped to service
your loader quickly.
