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 technology capitalizes on Cat expertise in four core engine systems: fuel, air, electronics and after treatment. ACERT technology is a unique and revolutionary systems solution that enables Cat engines to meet today's clean air regulations, thus establishing the building blocks for attaining tomorrow's more stringent standards.

The one-piece, gray iron block features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. Straight O-ring connection points reduce the loss of engine oil and fluids.

The C15 ACERT engine has a cross-flow cylinder head with refined port geometry, which provides improved breathing and better combustion. The Monotherm/steel pistons have a forged steel design, which offers high strength, light weight and tighter tolerances. The result is better oil control, minimal blow-by and long liner life.

The ADEM™ A4 electronic control module manages fuel delivery to get the best performance per liter or gallon of fuel used. The engine management system provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It tracks engine and machine conditions while keeping the engine operating at peak efficiency.

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.

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 refinements.

A highly evolved fuel system with a proven record of reliability in the field. It combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. It excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C15 to have complete control over injection timing, duration and pressure.

ATAAC keeps air intake temperatures down and, in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. Significant improvements in air flow are generated by a turbocharger, unique cross-flow head and a single overhead camshaft.

Single wastegate turbocharger provides higher boost over a wide range, outstanding low-end performance with improved peak torque and engine response.

The Caterpillar seven-speed electronically controlled transmission is designed specifically for the articulated truck and its applications. It features anti-hunt shift shift strategy for speed continuity. It also incorporates Individual Clutch Modulation (ICM) to ensure constant shift times even when the oil is cold.

The transmission arrangement provides a second reverse gear for improved performance when operating in longer rear hauling applications. First gear reverse is now of a lower ratio for increased rimpull on wet or steep grades.

Significantly reduces power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagements.

Provides extra braking effort on downhill grades. It is an excellent match for the C15 ACERT engine, turning it into a power absorbing air compressor. It has very fast response time and produces no additional heat, so it can be used continuously.

Power train components work together to offer more usable rimpull at higher speeds on effective grades. In first gear, the torque converter overcomes grade resistance by sending more torque to the wheels and preventing engine lugging. On downhill grades, the engine compression brake works like a brake by slowing the machine.

The remote-mounted hydraulic fan is temperature sensitive providing variable speeds when needed, which minimizes power requirements. The result is more power to the ground and faster cycle times.

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.

Features a walking beam geometry with Caterpillar designed rear suspension mounts which provide a reliable and stable ride for excellent load retention.

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.

Locks all three axles in unison and modifies torque distribution for excellent traction in poor underfoot conditions and on grades. It is operated by a switch located at the footrest.

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.

Fast body raise and lower times mean less time spent in the dump area.

Multi-plate, oil-immersed brakes are fitted to both front and center axles. These brakes provide outstanding stopping capability, while maintaining maximum durability and low wear characteristics.

The body comes exhaust heat ready.

The 740 has a large target area to provide consistently high load-carrying capacity. Its diverging flow design gives clean load ejection, which maximizes production and avoids the waste of material carry-back.

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.

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.

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.

Plenty of storage space to create a safe, secure and uncluttered working environment.

Full-size trainer seat features a fully padded seat with a backrest and a wide, retractable seatbelt for a secure and comfortable ride. The trainer seat is positioned next to the operator seat, giving both the operator and trainer a clear view of the instrument panel, controls and the road.

Twelve vents provide air distribution to keep the operator comfortable and to provide rapid defrosting of all windows. Heating, air conditioning and defrosting are standard. The recirculation filter is positioned for easy servicing.

The radiator is mounted at an angle to prevent heat transfer to the cab.

The right-hand window is a dual-sliding window. Opening this window with the left rear hinged window provides cross-flow ventilation and enhanced operator comfort.

Cab mounts are designed to reduce noise and vibration in the cab. All connections to the cab are resiliently mounted. The operator's station makes extensive use of sound-absorbing and barrier materials to keep sound levels low.

A comfortable driving position is provided by a telescopic and tilt steering column.

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.

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.

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.

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.

The inter-axle differential lock is engaged/disengaged 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.

The hoist lever provides easy, comfortable operation. The transmission lever offers excellent comfort, along with the control for top gear limit, transmission hold and neutral lock.
