Speed
Torque Rise. The direct injection
electronic fuel system provides a
controlled fuel delivery increase as
the engine lugs back from rated speed.
This results in increased horsepower
below rated power. A combination
of increased torque rise and maximum
horsepower improves response,
provides greater drawbar pull and
faster dozing cycles.
Cooling System. The cooling system is
a single coolant unit including hydraulic
oil cooler, radiator, ATAAC and fan
installation. Aluminum cores and
hydraulically driven demand fan provide
optimum cooling and fuel efficiency.
Electric Fuel Priming Pump. A standard
electric fuel priming pump is located in
the primary fuel filter base above the
combined water separator/primary fuel
filter. A switch enables to easily prime
the fuel system after a fuel filter service.
Cat®C6.6 Engine with ACERT™
Technology. The Cat®C6.6 is a
6.6 liters (403 in3) displacement,
six cylinder, inline configured engine
equipped with a Caterpillar Common
Rail fuel System. It uses ACERT
Technology, a series of Caterpillar
engineered innovations that provide
advanced electronic control, precision
fuel delivery and refined air management,
resulting in outstanding performance
and lower emissions. The Cat C6.6 with
ACERT Technology meets the U.S. EPA
Tier 3, European Union Stage IIIA and
Japan MOC Step 3 emissions standards.
Design. The C6.6 features a compact
design with heavy-duty engine features
for outstanding durability, reliability
and performance. The C6.6 incorporates
a new cross flow cylinder head design,
a 4 valve head and an ADEM A4
electronic controller.
Electronic Controls. The C6.6 engines
use advanced electronic controllers,
which have a proven track record for
performance and reliability. ADEM A4
Electronic Control Module (ECM)
receives data from engine-mounted
sensors and adjusts critical parameters
to maintain optimum performance.
These adjustments also optimize fuel
economy and emissions compliance.
Electronics also make engines easier
to troubleshoot and repair.
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
process. The ADEM™ A4 module
directs the injectors to deliver precise
quantities of fuel at exactly the right
times during combustion for optimum
efficiency and performance.
Air Management. The C6.6 uses a
turbocharger fitted with a smart waste
gate to give precise control of the boost
pressure. Over the entire engine operating
ranges the result is improved: Throttle
response, Lower fuel Consumption and
optimized engine performance. A new
cross-flow design in the cylinder head
facilitates air movement, while tighter
tolerances between the piston and
cylinder liner are reducing blow by gases.

Structure
The frame is engineered to handle the most demanding applications, and is built to last
throughout the extended service life of the D6K.
Main Frame. The D6K one-piece main
frame is designed to absorb high
impact shock loads and twisting forces.
Robotic welding provides deep
penetration and consistency, ensuring
high quality, durability and reliability
throughout the structure.
Track Roller Frame. Track roller frames
feature an engineered box-section
design, which provides superior
strength and resistance to bending.
Equalizer bars are pinned in their
center to the machine main frame and
at the ends to each track roller frame.
This allows the forward ends of the track
roller frames to oscillate to keep more
track on the ground in uneven underfoot
conditions while providing maximum
traction and operator comfort.
Heavy Duty Components. Heavy duty
radiator grill, bottom guards and fuel
tank guard are available, for additional
protection in severe applications.

Drive Train
The D6K features an electronically controlled hydrostatic drive system with independent
power and control of each track for fast acceleration, variable speed control, and on-the-go
direction changes.
Hydrostatic Drive. The electronically
controlled hydrostatic drive system
automatically maintains engine speed
to match the power requirements of
the application for peak performance.
The hydrostatic drive train also offers
independent power and control of each
track, for fast acceleration, infinitely
variable speed control and on-the-go,
direction changes. The operator can
command smooth “power turns” or
even counter-rotation of the tracks for
precise steering control in tight areas.
The Caterpillar hydrostatic drive system
manages itself, freeing the operator to
concentrate on using the Caterpillar
track-type tractor’s superb agility, speed,
and maneuverability to do more
productive work.
Infinitely Variable Speed Control.
Hydrostatic drive provides infinite
speed selection from 0 to 10 km/h
(0 to 6.2 mph) in forward and reverse.
This lets the operator select the optimum
speed for ground and job conditions.
It also eliminates power interruption
during shifting.
Ground Speed Balancing. Hydrostatic
drive provides a completely “step-less”
transmission of power and automatically
matches travel speed and implement
loads for increased efficiency and easier
operation.
High Power Utilization. The hydrostatic
drive system on the D6K is designed
to use full available engine power
throughout the machine working cycle.
If the implement hydraulic system is not
in use, this engine power can be
delivered to the drive train, providing
high drawbar pull and fast travel speeds.
If the implement hydraulics are being
worked hard, the machine control ECM
will automatically slow the tracks as
necessary to use the full remaining
engine power, without overloading
and stalling the engine. As soon as the
implement hydraulic load is decreased,
the machine control ECM will
automatically speed up the tracks until
the machine is traveling at the speed
the operator has commanded with the
Hystat Control (left).
Unsurpassed Maneuverability.
Power turn and counter-rotation capability
improve machine maneuverability and
productivity. On the D6K, power turns
are accomplished by slowing the speed
of one track versus the other, while
maintaining power to both tracks.
The Cat Hystat power turn feature also
enables the D6K to handle large loads
around corners or through hard spots
encountered when dozing. Power turn
capability improves machine mobility
in soft underfoot conditions and is
very effective for controlling machine
operation on side slopes. Counter-rotation
also provides easy, quick maneuvering
in tight areas or congested job sites.

SystemOne™ Undercarriage
Exclusively for Caterpillar machines the SystemOne™ Undercarriage is a revolutionary new
undercarriage system – from the ground up.
SystemOne™ Undercarriage.
Exclusively for Caterpillar machines the
design extends system life and reduces
operating costs.
• Long-life Sprocket. Extended life
sprockets will outlast two or more
tracks. The rotating bushing
technology extends life.
• Guiding System. The guiding
system contacts link rails instead
of pin ends and helps keep the track
within the roller system. The result
is improved track guiding.
• Rollers. The increased flange
diameter on the rollers provide
optimum guiding and longer life.
• Carrier Rollers. Redesigned carrier
rollers are factory sealed and serviced
as a unit. The larger diameter provides
extended wear to better match
undercarriage system life.
• Idlers. The center tread idlers
contact only the bushing – not the
links – eliminating scalloping and
providing more guiding to the link
assembly. The idlers last longer
because they contact a rotating
bushing instead of a link rail.
• Cartridge Joints. Factory-sealed
cartridge joints are laser welded to
control end play. They offer improved
seal integrity through an innovative
new sealing system and do not
depend on the link interface to
remain sealed. As with all Cat
undercarriage products, they are
filled with special oils.
• May be used in any application.
• The track roller frames are welded
and have a box section design,
which provides strength and
resistance to bending without
adding extra weight.
• The track adjuster and mechanical
recoil spring and grease filled
adjustment cylinder which allows
the idler to move forward and back
to maintain proper track tension as
it absorbs undercarriage shock.
Undercarriage Arrangements.
XL (Extra Long) arrangement
• Forward idler position provides
more track on the ground and to
the front of the tractor. It provides
optimal balance, superior traction
and blade control for finish grading.
• Long roller frame provides good
flotation in soft underfoot conditions.
LGP (Low Ground Pressure)
arrangement
• Specially designed to work in soft
underfoot conditions.
• Wide track shoes, a longer track
frame and a wider gauge increase
track contact area and reduce ground
pressure for excellent flotation.
Complete Guarding. Caterpillar
undercarriages are designed with full
length guarding on top of the track
roller frame. This prevents abrasive
materials from being recirculated in
the track.
Roller Frames. Roller frames attach to
the tractor by a pivot shaft and pinned
equalizer bar.
Oscillating Undercarriage. The pinned
equalizer bar is saddle-mounted
beneath the mainframe, allowing the
roller frames and track to oscillate.
The oscillation provides a steady
working platform and smooth ride
for the operator.

material with new technology solutions
for earthmoving machines – solutions
that provide greater accuracy, higher
productivity, lower operating costs and
more profitability.
The AccuGrade System is designed and
integrated into the machine and hydraulic
systems to create an automated blade
control system that allows operators to
grade with increased accuracy.
The system uses machine-mounted
sensors to calculate precise blade slope
and elevation information.
The integrated electrohydraulic valve
control module uses the information
received from the sensors to automatically
adjust the blade to maintain grade.
Automated blade control allows
operators to improve efficiency and
productivity by achieving grade faster
and in fewer passes than ever before,
reducing the need for traditional survey
stakes or grade checkers.

AccuGrade Laser. AccuGrade Laser
designed for precise grade control using
a laser transmitter and receiver.
A laser transmitter is set up on the
work site and creates a constant grade
reference over the work area. A digital
laser receiver is mounted on the machine
and captures the laser signal as the
machine moves across the work site.
The system captures information and
calculates the blade adjustments
necessary to achieve grade. The system
makes automatic elevation adjustments
typically performed by the operator
and provides automatic blade control.
The operator simply steers the machine.
The system also calculates cut/fill
requirements for manual blade control.
AccuGrade GPS. AccuGrade GPS
computes the positioning information
on the machine, compares the position
of the blade relative to the design plan
and delivers that information to the
operator via an in-cab display.
Information, such as blade elevation,
necessary cut/fill to achieve grade,
visual indication of the blade’s position
on the design surface and a graphical
view of the design plan with machine
location.
AccuGrade GPS puts all the information
the operator needs to complete the job
in the cab, resulting in a greater level of
control. Vertical and horizontal guidance
tools visually guide the operator to the
desired grade.
Automated features allow the hydraulic
system to automatically control blade
adjustments to move the blade to grade.
The operator simply uses the light bars
to guide the machine for consistent,
accurate grades and slopes, resulting
in higher productivity with less fatigue.
