Engine with ACERT™ Technology
Innovative technologies optimize performance.
ACERT Technology
The Cat C15 ACERT engine introduces a series of
evolutionary, incremental improvements that provide
breakthrough engine technology built on systems and
components developed by Caterpillar with proven reliability.
The ADEM A4 electronic control module manages fuel
delivery and provides exible fuel mapping, allowing the
engine to respond quickly to varying application needs.
Fuel Delivery
Multiple injection fuel delivery involves a high degree of
precision. Precisely shaping the combustion cycle lowers
combustion chamber temperatures, generating fewer emissions
and optimizing fuel combustion. This translates into more
work output for your fuel cost.
Transmission
Proven Reliability.
Electronic Transmission
The Caterpillar seven-speed electronically controlled
transmission features anti-hunt shift strategy for speed
continuity, and Individual Clutch Modulation (ICM)
to ensure constant shift times.
Controlled Throttle Shifting (CTS)
Signicantly reduces power train stress and clutch wear
by controlling engine speed, torque converter lock-up
and transmission clutch engagements.
Noise Reduction Technologies
Noise reduction has been achieved through design changes
to the isolated top cover, oil pan, multiple injection strategy,
insulated timing case cover, sculpted crankcase and gear
train renements.
Two Reverse Gears
The transmission arrangement provides a second reverse
gear for improved performance when operating in longer
rear hauling applications.

a smooth ride, allowing the operator to travel at speed over
rough terrain and softening impact loads on structures and
components. Large bore, low pressure cylinders are purpose
designed for tough applications and offer a soft, smooth ride.
Enclosed, Oil-Cooled Brakes
Multi-plate, oil-immersed, oil-cooled brakes are tted
1
to both front and center axles. These brakes provide
outstanding stopping capability, while maintaining
maximum durability and low wear characteristics.
Rear Suspension
Features a walking beam geometry with Caterpillar designed
rear suspension mounts which provide a reliable and stable
ride for excellent load retention.
Traction Control
The traction control system is comprised of a wet
clutched inter-axle differential and wet clutched cross-axle
differentials. All differentials can be engaged and disengaged
“on-the-go” for maximum versatility. When used together,
the differentials provide 100 percent driveline locking.
Inter-Axle Differential Lock
Locks all three axles in unison and modies torque
distribution for excellent traction in poor underfoot
conditions and on grades. It is operated by a switch located
at the footrest.
Cross-Axle Differential Locks
Provides full driveline locking – all three axles and all six
wheels – for maximum performance in the most adverse
conditions. Acts in unison with the inter-axle differential
lock when the footswitch is actuated and the dash-mounted
switch is selected.

Ease of Operation
Designed for ease of use – allows the operator to focus on production.
Ergonomic Layout
The controls and layout of the cab are designed to make it
as easy to operate as your car. Quick, easy to read and simple
to operate, the controls and gauges allow the operator to
concentrate on production.
Dash
The Generation II wrap-around dash puts all controls within
easy reach of the operator. Featuring LED illuminated rocker
switches, large LCD display and a rear wash wipe rocker
switch. It provides an automotive feel with the industrial
strength you would expect from Caterpillar.
Viewing Area
The low sloping hood and placement of the cooling package
behind the cab give the operator excellent all-around
visibility. The large glass area and central operator position
also provide excellent visibility.
Wipers
The wet arm wiper system cleans more glass area and
is bottom-mounted to keep it out of the operator’s line
of sight. Windows are tinted to reduce glare.
Differential Lock Controls
The inter-axle differential lock is engaged/disengaged
“on-the go” by using a raised switch incorporated into the
drivers foot rest, for ease of operation. For 100% lock up,
all three cross-axle differential locks act in unison with the
inter-axle differential lock when the foot switch is activated
and a dash mounted switch is selected. Disengaging the foot
switch opens all differential locks immediately.
Transmission and Ejector Levers
Finger tip controls allow easy operation and low effort.
The ejector and transmission levers are positioned for easy,
comfortable operation, along with the control for top gear
limit, transmission hold and neutral lock.
Blade Retraction Sequence
The ejector blade returns to the loading position as soon
as the blade retract sequence is initiated. The transmission
is held in the gear selected for the ejecting cycle until this
sequence is completed and the ejector control lever is
returned to the oat position.
Suspended Pedals
Easy to operate and reach with plenty of leg and foot room.
They also make for easier cleaning of the cab oor by
keeping the pedals out of the dirt.

To determine performance, read from Gross Weight down to % Total Resistance. Total Resistance equals actual % grade plus 1% for each
10 kg/metric ton (20 lb/ton) of Rolling Resistance. From this point, read horizontally to the curve with the highest attainable speed range.
Then, go down to Maximum Speed. Usable Rimpull depends on traction available.
To determine performance, read from Gross Weight down to % Effective Grade. Effective Grade equals actual % favorable grade plus 1% for
each 10 kg/metric ton (20 lb/ton) of Rolling Resistance. From this point, read horizontally to the curve with the highest attainable speed range.
Then, go down to Maximum Speed. Retarding effect on these curves represents full application of the retarder.
