Performance and Productivity – PowertrainIntegrated powertrain with more power, greater performance and lower fuel consumption –the power to do more work.3406E Electronic Engine. The electronicversion of this proven engine delivershigher power, durability and completesystem integration of the engine andtransmission for maximum efficiency.High Torque Rise. Provides unequaledlugging force during acceleration, onsteep grades and in tough underfootconditions.Turbocharged and ATAAC. Air-to-airaftercooling provides improved fueleconomy by packing cooler, denser airinto cylinders for more completecombustion of fuel and loweremissions.Electronic Control Module (ECM).Advanced Diesel EngineManagement III (ADEM III) providesimproved emissions, performance,advanced troubleshooting anddiagnostic capabilities.Fuel Efficiency. The electronicallycontrolled, computer actuated unitinjection fuel system has high injectionpressure for complete fuel combustion,greater fuel efficiency and reducedemissions.Controlled Throttle Shifting (CTS).CTS significantly reduces powertrainstress and clutch wear by controllingengine speed, torque converter lock upand transmission clutch engagements.Engine Construction. Since 1974,the 3406 engine has been the benchmarkfor heavy-duty reliability andperformance. The latest electronicversion incorporates major updates tokeep it ahead of the rest. Cylinder headwith overhead camshaft and a pendulumshock absorber improve efficiency andincrease reliability.Electronic Transmission. The sevenspeedelectronic transmission is basedon the proven design of the Cat769 Off-Highway <strong>Truck</strong>. It featuresIndividual Clutch Modulation (ICM)to ensure constant shift times evenwhen the oil is cold.Engine Compression Brake.The standard Jake Brake ® providesextra braking effort on downhill grades.It is an excellent match for the 3406Eengine, turning it into a powerabsorbingair compressor. It has veryfast response time and produces noadditional heat, so it can be usedcontinuously. Four modes of operationprovide an optimum match betweenoperating conditions and retardingpower.4
Performance and ProductivitySuspension systems and traction control – delivering power to the ground in all conditions.Front Suspension. New front suspensionoscillates ±6° to provide a smootherride, allowing the operator to travelfaster over rough terrain and softeningimpact loads on structures andcomponents.Rear Suspension. Features a walkingbeam geometry that provides a stableride for excellent load retention.Traction Control. The traction controlsystem is comprised of a wet clutchedinter-axle differential and wet clutchedcross-axle differentials. All differentialscan be engaged and disengaged on-thegofor maximum versatility. When usedtogether, the differentials provide100 percent driveline locking.Inter-Axle Differential Lock. Modifiestorque distribution to give a fixed 50/50torque split between tractor and trailerfor excellent traction in poor underfootconditions and on grades. It is operatedby a switch in the footrest.Cross-Axle Differential Locks. Providesfull driveline locking – all three axlesand all six wheels – for maximumperformance in the most adverseconditions. Acts in unison with theinter-axle differential lock when thefootswitch is actuated and the dashmountedswitch is selected.Oil-Immersed, Oil-Cooled Brakes.Multi-plate oil-immersed brakes arefitted to both front and center axles.These brakes provide outstandingstopping capability, while maintainingmaximum durability and low wearcharacteristics.Fastest Hoist Cycle Times. Carried overfrom the E Series II, fast body raise andlower times mean less time spent in thedump area.Load-Carrying Capacity. The <strong>740</strong> has alarge target area to provide consistentlyhigh load-carrying capacity.Its diverging flow design gives cleanload ejection, which maximizesproduction and avoids the waste ofmaterial carryback.Service brake detail5
