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.
Advanced Diesel Engine Management (ADEM)
A4 Engine Controller
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.

Suspension and Traction Control
Performance and Productivity.
Front Suspension
The three-point front suspension oscillates ±6° to provide
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 brakes are tted 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.

Operator Comfort
High productivity from a comfortable, confident operator.
Ride Comfort
The three-point front suspension with its oscillating axle and low-pressure ride struts, combined with
the center-mounted cab, offers unrivaled levels of ride comfort for the operator in all driving conditions.
The operator remains comfortable and productive throughout the day.
Spacious Two-Person Cab
The 740 features a large two-person cab, offering comfortable working space for both the operator
and trainer or trainee. All 700 Family articulated trucks use the same spacious cab design.
Air Suspension Seat
The air suspension seat enhances operator comfort with a cushioned upper high back, adjustable
damping with three settings, ride zone indicator and adjustable lumbar settings. It is fully adjustable
to provide the optimal driving position.
Trainer Seat
Full-size trainer seat features a fully padded seat with a backrest and a wide seatbelt for a secure and
comfortable ride. The trainer seat is positioned next to the operator seat, giving both the operator and
trainee a clear view of the instrument panel, controls and the road.
Steering Column
A comfortable driving position is provided by a telescopic and tilt adjustable steering column.

Page 6
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 on the 740 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 can be 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 interaxle 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 Hoist Levers
The hoist lever provides easy, comfortable operation.
The transmission lever offers excellent comfort, and control
for top gear limit, transmission hold and neutral lock.
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.
Cat 2S Monitoring System
Provides an improved method of monitoring critical
machine functions and alerts the operator to an immediate
or impending problem. The system includes four levels
of warning.
