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 Truck. 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 740 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

Operator ComfortThe operator’s office – high productivity from a comfortable, motivated operator.Ride Comfort. The new front suspensionwith its oscillating axle and lowpressure ride struts, combined withthe new center-mounted cab, offersunrivaled levels of ride comfort forthe operator in all driving conditions.Operators remain comfortable andproductive throughout the day.Spacious Two-Person Cab.The 740 features a large two-person cab– 41 percent larger than the E Series II –offering comfortable working space forboth the operator and trainer or trainee.All 700 Family articulated trucks usethe same spacious cab design.Cat Comfort Seat. The new Cat Comfortair suspension seat enhances operatorcomfort with a dual-sided supportrecliner and thicker cushions. It is fullyadjustable to provide an optimal drivingposition.Trainer Seat. Full-size trainer seatfeatures a fully padded seat with abackrest and a wide seatbelt for a secureand comfortable ride. The trainer seat ispositioned next to the operator seat,giving both the operator and trainer aclear view of the instrument panel,controls and the road.Storage Space. More storage space tocreate a safe, secure and unclutteredworking environment.Heating/Ventilation/Air Conditioning.Twelve vents provide air distribution tokeep the operator comfortable and toprovide rapid defrosting of all windows.Heating, air conditioning and defrostingare standard. The recirculation filter ispositioned for easy servicing.Sound Levels. Cab mounts are designedto reduce noise and vibration in the cab.All connections to the cab are resilientlymounted. The operator’s station makesextensive use of sound-absorbing andbarrier materials to keep sound levelslow.Steering Column. Offers telescopingand tilting features to provide acomfortable driving position.6

ServiceabilityMore time on production, less time and money spent on servicing.Extended Service Intervals. Increasedengine oil change and hydraulic oilchange intervals.Test and Lube Points. Test points aregrouped together behind the cab and areaccessible from the ground. Lube pointsare grouped at the rear of the frontframe and the front of the rear frame.Service Points. Engine and transmissiondipstick and fill caps, air and fuel filtersand the fuel-priming pump are allmounted on the left side of the engineunder the hood. Coolant level indicatorand fill cap are outside the cab.Radiator. The radiator package islocated behind the cab, which providesimproved access to both inlet and outletsides of the radiator. The ATAACradiator is located at the front of thetruck.Extended Life Coolant. Extends thechange interval and improvescomponent life by reducing aluminumcorrosion.Hood. The hood is raised and loweredelectrically, minimizing operator effortwhen servicing the machine. A manualoverride is also provided.Electrical Service Center. Locatedinside the cab, this service centerprovides a power port, diagnosticconnector and Cat Data Link connector.Cat Data Link Connector. The Cat DataLink connector provides a plug-in usinga laptop computer with ElectronicTechnician (ET) software. The Cat DataLink port performs programmingfunctions on all electronic controls.Service Access. The cab tilts to the sideto provide easier access underneath,which simplifies servicing of thetransmission, drive shafts and hydraulicpumps. Accessibility to machineelectrical and hydraulic interfaces hasalso been improved. They are locatedon the right side of the cab, behind aremovable cab body panel.Truck Transport. The new suspensionsystem eliminates the need to lower thesuspension when transporting the truck,reducing maintenance and downtime.Output Transfer Gear. The OTGprovides lubrication of all bearings andclutches using a distributed-pressurelubricated and filtered system, whichreplaces the previous splash-lubricatedsystem on the E Series II. Betterlubrication and filtration reduce serviceand repair. In addition, improved lipseals on output yokes decrease thechance of leaks.9
