Engine Lubrication. Engine lubricatingoil is filtered, cooled and supplied bya gear-type pump.

Mechanical Electronic Unit Injector(MEUI™). MEUI is a high-pressure,direct injection fuel system that isvirtually adjustment-free. It electronicallymonitors operator and sensor inputs tooptimize engine performance.

Air-to-Air Aftercooler (ATAAC) System.The ATAAC system provides a separatecooling for the intake manifold air.It routes hot, compressed air from theturbo and cools it with a single pass,air-to-air aluminum heat exchanger.The cooled, compressed air greatlyreduces the emissions produced,meeting U.S. EPA Tier 3/EU Stage IIIrequirements.

• Airflow matched turbocharger withpower rating helps reduce emissions.

• 19 percent more bearing area allowsthe engine to operate at the maximumcylinder pressure.

• Higher cylinder pressure capabilityhelps reduce fuel consumption andimproves high altitude operation andprovides reduced emissions.

Cylinder heat exhaust port sleevesreduce heat rejection which results inless heat transfer into the water jacketsystem and provides high torque rise.

Next Generation Modular Radiator(NGMR). The parallel flow system withsix cores standard (seven on the highambient machine) improves coolingcapabilities. Serviceability is alsoenhanced as there is no top tank toremove. The NGMR uses copperbrazed brass tubes and copper fins.

ADEM™ IV (Advanced Diesel EngineManagement) System. ADEM IV uses a32-bit computer with sensors throughoutthe engine to regulate fuel delivery,valve timing and all other enginesystems that require input to manageload and performance.

ADEM IV also offers automatic altitudecompensation, a cold mode start-upstrategy, oil pressure and coolantwarnings which result in precise enginespeed control, superior cold startcapability, low smoke and emissionsin all operating conditions.

Power Train

Torque Converter. The torque converteruses a high-capacity impeller to handlethe engine’s increased torque rise(24 percent) and power.

Heavy-Duty Axles. The fixed front andoscillating (±13 degrees) rear heavy-dutyaxles feature strong gears and bearingsin both the differentials and heavy-dutyfinal drives for increased durability.Permanently lubricated, maintenance-free U-joints result in fewer parts andimproved serviceability. Free floatingaxles shafts can be removed independentlyfrom the wheels and planetary drives.

Spindles and Final Drives. Planetaryunits can be removed independentlyfrom the wheels and brakes. The finaldrives feature planetary reduction ateach wheel, and with torque developedat the wheel, less stress is placed onthe axle shafts.

Differentials. Conventional front andoptional No-SPIN rear differentialsdeliver maximum traction in low tractionor inconsistent ground conditions.

Service Brakes. Completely enclosedand located on the two front wheels, theservice brakes are self-adjusting withmodulated engagement and are designedfor easy servicing. With two brakepedals, the right pedal controls standardbraking while engine deceleration andbraking occurs with the left pedal.

Parking Brake. The spring-applied, oil-released, dry drum design parking brakeis mounted on the transmission outputshaft driveline for manual operation.The Caterpillar® Monitoring Systemalerts the operator if the transmissionis engaged while the parking brakeis applied.

Hydraulic System. The hydraulicsystem provides low-effort blade control.Seat mounted levers send electricalsignals to a pilot valve mounted onthe front frame, moving the sound,heat and effort caused by the hydraulicvalve out of the operator’s station.

Command Control Steering. A mechanicalfeedback system combines with valveratio to provide quarter-turn, side-to-side steering. Unlike systems that relyon steering wheel velocity to activatesteering cylinders, Command Controlsteering directly links the steering wheelposition to articulation. The speed themachine turns is proportional to thesteering wheel position. The benefit isprecise control, quicker response anddramatically reduced operator motionand effort.

Hydraulic Power Steering. Center-pointframe articulation permits the frontand rear wheels to track with hydraulicpower steering. The hydraulic systemhas full-flow filtering. The steeringwheel operated pilot valve controls flowto the steering cylinders. The steeringangle is ±42 degrees.

Load Sensing Steering. With loadsensing steering, machine performanceis maximized because power is directedto the steering system only when theoperator steers the machine. This allowsmore power to be applied to the groundwhen the machine is not being steered.It also helps decrease fuel consumptionsince the steering system does notconstantly draw on the engine.

Positive Displacement Hydraulic Pumps.All hydraulic pumps are mounted ona single pump drive for improvedserviceability

XT™-3 and XT™-6 Hose. ReliableXT-3 ES and XT-6 ES hoses, alongwith o-ring face seals and a largecapacity life cylinder complete thehydraulic system. Reliable componentsreduce the risk of leaks and blown lines,helping protect the environment andreducing operating costs.

Automatic Blade Positioning.Operator automation is providedthrough the use of in-cylinder sensorsand implement software.

HydraulicsWell-balanced hydraulics deliver precise, low-effort control and trouble-free operation.

Structure Construction. Combines theuse of robotic welding on up to 90 percentof the 824H, while castings are used inseveral areas to increase strength byhelping to spread the loads and reducethe number of parts. This provideshighly consistent welds with deep platepenetration and excellent plate fusion.The benefits are increased durability andfatigue strength. The computer controlledmachining ensures the alignment ofpin bore, axle pad, cab mount andtransmission/engine components.

Box Section Engine End Frame.Designed to resist twisting and torsionalforces, the box section engine end frameprovides a solid foundation for theaxles, engine and transmission.

Dozer Front Frame. Built specificallyto handle greater amounts of rimpull,the 824H can readily push its weightplus the weight of the material for longdistances in heavy dozing applications.

Spread Hitch Design. The spread hitchdesign improves load distribution byreducing loads to the hitch bearings.The large center hitch design improveshydraulic line routing and makesservice access easier.

Upper and Lower Hitch Pins. The hitchpins pivot on double-tapered rollerbearings. Box-style sections in thehitch pins and crossmember assemblyimprove frame structure strength.Increased diameter lower hitch pinsadd to the robust design.

Engine and Transmission Mounts.A rubber isolation mount designreduces noise and vibration.
