163H All-Wheel Drive Motor Grader : AEHQ5269 - Kelly Tractor

Power TrainMatched Caterpillar components deliver smooth, responsive performance and reliability.Cat 3306 engine continues its traditionof powerful, efficient performance andunmatched reliability and durability.The six-cylinder engine is turbochargedwith a high displacement-to-powerratio. This large displacement producesbetter lugging capability, lower internalstresses and extended component life.Superior lugging performance. Hightorque output and high torque rise makethe 3306 engine very responsive. Theengine’s lugging capability allows it topull through sudden, short-termincreases in loads, reducing the need todownshift. As a result, the operator canmaintain desirable working speeds,which means the work gets done faster.Fuel efficiency. High fuel injectionpressures ensure proper mixing of fueland air. This high injection pressure,coupled with the precise metering andtiming of the fuel injection, results insuperior fuel efficiency and reducedemissions. High compression ratiosensure dependable cold-startingperformance and low emissions.Extended engine life. The large borestrokedesign and conservative powerrating help minimize internal stressesand increase component life. The lowengine speeds reduce engine wear andsound levels.Variable horsepower comes standardand can deliver an additional 15 kW(20 hp) in gears 4 - 8 forward whenall-wheel drive is turned off. Whenall-wheel drive is engaged, it deliversfull power in all gears. Variablehorsepower produces higher rimpull formoving heavy loads in applicationssuch as high-speed blading and snowremoval. It also improves gradeabilitywhen roading or working in the highspeedranges.Electronic overspeed protection helpsprevent engine and transmissiondamage from premature downshiftingand grade-induced overspeeding.4

Power shift transmission. Caterpillardesigns and builds transmissionsspecifically for Cat motor graders. Thetransmission provides on-the-go, fullpowershifting as well as inchingcapability.Direct drive delivers superior fuelefficiency and better “feel” of bladeloads, material hardness and groundspeed.Gear selections. Eight forward speedsand six reverse speeds give the operatora wide operating range. With four gearselections below 9.7 km/h (6 mph), theoperator can precisely match workingspeeds to job conditions for maximumproductivity in earthmovingapplications. Gears five, six and sevenprovide the optimal speed range forefficient snow removal operations.Electronic transmission controlproduces easy, smooth shifts, whichenable the operator to maintain uniformsurfaces if shifting is required. Smoothshifts also extend the life of thetransmission by placing less stress ontransmission clutches. A single levercontrols direction, speed and theparking brake.Inching capability. Low pedal effortand excellent modulation provideprecise control of machine movementswhen using the inching pedal. This isespecially important in finish grading orother close-quarter work where machinecontrol is critical.Optional autoshift improves ease ofoperation and maximizes productivityby automatically shifting thetransmission at optimal shift points.Dual air system supplies brakingcapacity to each side of the machine.This system ensures secondary brakingcapability in the event a failure occursin a single brake line. The dual airsystem also has a large reserve forstalled-engine braking.Oil-disc brakes. Caterpillar designs andbuilds multi-disc brakes that arecompletely sealed and adjustment-free.The brakes are oil-bathed, air-actuatedand spring-released. They are located ateach tandem wheel to eliminate brakingloads on the power train and to reduceservicing time. The large brake surfaceprovides dependable braking capabilityand extended life before rebuild.5

Drawbar, Circle & MoldboardEvery component is designed for maximum productivity and durability.Blade positioning. The blade linkagedesign provides extensive moldboardpositioning. This extended range ismost beneficial in mid-range banksloping and in ditch cutting andcleaning.Blade angle. A long wheel base allowsthe operator to obtain an aggressivemoldboard angle. This aggressive anglepermits material to roll more freelyalong the blade, which reduces powerrequirements. This is particularlyhelpful in handling very dry materials,cohesive soils, snow and ice.Rugged construction. The Y-framedrawbar is constructed of two solidbeams. A one-piece forged circle isbuilt to stand up to high stress loads.To resist wear, teeth are inductionhardenedin the critical areas. Formaximum support, the circle is securedto the drawbar by six support shoes.Replaceable wear items. Tough,durable nylon composite wear insertsare located between the drawbar andcircle, and between the support shoesand circle. This wear system helps keepcomponents tight for fine grading andallows easy replacement. In addition toproviding extended life, these insertsallow higher circle turning forces byreducing the friction between the circleand drawbar. Replaceable metallicwear inserts are used in the blade liftand centershift cylinder sockets,draftball surface, moldboard slide railand tip bracket bearings.Circle drive slip clutch protects thedrawbar, circle and moldboard fromshock when the end of the bladeencounters hidden objects. It alsoreduces the possibility of the gradermaking abrupt directional changes,further protecting the machine, operatorand surroundings.Optional blade lift accumulators absorbvertical shocks encountered when themoldboard contacts immovable objects.This option is especially useful in roughgrading and rocky areas.7

Operator’s StationCaterpillar sets the standard for comfort, convenience and visibility.8

Exceptional visibility helps improveoperator confidence and productivity.The drawbar has been modified toimprove the view through the circle,allowing the operator to see the materialas it rolls along the moldboard withoutleaning. Large side windows allow aclear view of the moldboard heel andtandem tires. A wide rear window andtapered engine hood provide a goodview to the rear of the machine.Quiet cab. With the doors closed,interior sound level does not exceed77 dB(A) when tested using SAE J919standard. The quiet environment keepsthe operator alert and focused.Low efforts on all pedals, hydrauliccontrols and the transmission shifterreduce operator strain and fatigue.Pedals are angled and raised off the cabfloor to make them easy to reach.All-Wheel Drive. Using the rockerswitch on the transmission console, theoperator can choose from threeoperating modes — automatic, manualor off. The torque control lever allowsthe operator to control theaggressiveness of the front wheels inboth active modes.Roomy interior. Extra leg and foot roomcreate a spacious, open cab. The cabincludes built-in storage space forpersonal items such as a lunch box,cooler and coat.Contour series suspension seat featuresfold-up armrests and a retractable seatbelt. The seat follows the contours ofyour body and can be easily adjusted foroptimal support and comfort. Seatcontrols are located in front and to theleft of the operator in plain view.Optional air conditioner and heaterarrangements create a comfortablework environment for the operator.Both arrangements use high-capacitysystems to ensure the operator staysproductive — even in the bitter cold orheat and humidity. They dehumidify theair as well as pressurize the cab, whichkeeps the air fresh and seals out dust.The adjustable air vents evenlydistribute air throughout the cab,keeping the operator comfortable andthe windows clear of fog or frost.Electronic Monitoring System checksimportant machine systems andprovides the operator with three levelsof warning.Comfort and convenience are designedinto every feature:■ Engine start-stop switch enables theoperator to start and stop engine witha simple key turn.■ Gauges are located inside the cab,■■■■■■■■directly in front of the operator.Controls and switches are located onthe steering console, shift console andright cab post — all within easyreach.Rocker switches and transmissionshifter are backlit for nighttimeoperation.The operator can adjust implementcontrols and steering wheel angleindependently.Cab floor is flush with the bottom ofthe doors, making it easy to sweepout and keep clean.Fresh air filters are located aboveeach cab door for quick replacement.Cab door releases from ground levelor inside the cab.Ashtray, lighter and cupholder arewell-positioned for easy access.Optional 12-V powerport is availablefor use with computers, cellularphones or other electronic equipment.9

All-Wheel DriveAll-wheel drive keeps productivity high, even in poor underfoot conditions.Superior traction. All-wheel driveimproves tractive performance in poorunderfoot conditions such as snow, mudand sand. This feature also providesexcellent steering and sidedraft control.More power. The variable horsepowerfeature is standard on the 163H. Whenall-wheel drive is engaged, variablehorsepower kicks in and deliversmaximum power in all gears.Wide working range. All-wheel driveis available in gears 1-7 forward and 1-5reverse, making it effective in both lowspeedand high-speed applications —from ditch cutting to snow winging.Three operating modes are available —automatic, manual or off. The operatorselects the operating mode using arocker switch on the transmissionconsole.■ Automatic mode makes the all-wheeldrive feature easy to use. Itautomatically increases torque to thefront wheels as rear wheel slipincreases. The operator controls theresponsiveness of the front wheels byadjusting the torque control lever.The farther forward the lever, themore rapidly front wheel torque willincrease as slip increases.This mode provides power to thefront wheels only when needed,which reduces hydraulic system heatand lowers power consumption. Italso allows the operator to focus allhis attention on his work.■ Manual mode gives the operator 100percent control. He adjusts the torquecontrol lever to set a constant torquelevel to the front wheels. He canmake torque setting adjustments asoperating conditions change.There are many situations where anoperator may want to control the frontwheels independent of rear wheel slipsuch as when trying to remove amachine from a snow drift; whenmaking a tight turn on snow, mud orsand; or when working on a sideslope.10

ServiceabilityConveniently placed service points make routine maintenance quick and easy.Easy access to service areas speeds upmaintenance and ensures that routineservice is performed on time:■ Large hinged doors provide easyaccess to the engine and radiatorservice points.■ Spin-on filters make changes quickand clean.■ Lubrication points for the articulationjoint are remote-mounted.■ Disconnect switch and most servicepoints are located on the left side,making them easy to access when asnow wing is mounted on the rightside of the machine.■ Fuse panel is located inside the cab.Its cover clearly identifies circuitsand fuse sizes.■ Tandem oil checkpoint isconveniently located between thewheels in the center of the tandem.■ Service meter is located on the leftside of the steering console, givingthe operator a clear view from theground.■ Sampling ports are provided fordrawing engine and hydraulic oil.■ Lockable battery box cover is easilyremoved without tools.Power train components feature amodular design so you can remove theengine, transmission or final drivesindependently for quick servicing.Diagnostic capabilities offer fastservicing of the transmission andall-wheel drive system. The electroniccontrol modules automatically recordand save any system faults for lateranalysis. S•O•S oil and coolantsampling valves provide a fast,convenient means of obtaining fluidsamples and improve analysisreliability.XT hose. Caterpillar designs andmanufactures its own heavy-duty XThose and installs it in all high-pressurecircuits. Its resistance to abrasion,coupled with its exceptional strengthand flexibility, help minimizemaintenance and extend life.O-ring face seals create a reliable sealand are used in all hydraulic circuits tominimize the possibility of oil leaks.Radiator cleanout access. Removablecovers on each side of the radiatorguard provide access to the front of theradiator for cleanout with compressedair or pressure washer.Extended Life Coolant (ELC) extendscoolant life to 6000 hours. A singleaddition of ELC Extender at 3000hours is the only maintenance required.Separate wiring harnesses connect allelectrical components. This modularharness design provides simpledisconnects for major machine repairsor rebuilds. The wires are also colorcodedand numbered to speed updiagnosis and repairs.
