5 A modular design permits easy removalof power train components forservicing. pg. 10 Environmentally Responsible DesignThe engine arrangement is designed toreduce emissions and meet currentregulations of the EnvironmentalProtection Agency, California AirResources Board and European 114 Cat 3306 enginecontinues its traditionof powerful, efficient performance andunmatched reliability and six-cylinder engine is turbochargedand aftercooled with a highdisplacement-to-power ratio. This largedisplacement produces better luggingcapability, lower internal stresses andextended 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.

6 Fuel 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 large bore-stroke design and conservative powerrating help minimize internal stressesand increase component life. The lowengine speeds reduce engine wear andsound levels. Ether starting aid comes standard on the14H to help ensure engine starting inthe extreme cold. The system monitorsengine coolant temperature to preventether from being injected into a TrainMatched Caterpillar components deliver smooth, responsive performance and reliability. 5 Power shift and builds transmissionsspecifically for Cat Motor graders . Thetransmission provides on-the-go, full-power shifting as well as inchingcapability.

7 Direct drivedelivers superior fuelefficiency and better feel of bladeloads, material hardness and forward speedsand eight reverse speeds give theoperator a wide operating range. Withfour gear selections below km/h( mph), the operator can preciselymatch working speeds to job conditionsfor maximum productivity inearthmoving applications. Gears five,six and seven provide the optimal speedrange for efficient snow removaloperations. A single lever controlsdirection, speed and the parking brake. Planetary clutchpacks and oil cooling help dissipateheat, resulting in extended 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. Dual air systemsupplies brakingcapacity to each side of the system ensures secondary brakingcapability in the event a failure occursin a single brake line.

8 The dual airsystem also has a large reserve forstalled-engine designs andbuilds multi-disc brakes that arecompletely sealed and 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. 6 HydraulicsBalanced hydraulics deliver consistent, precise and responsive on , thevariable displacement pump idles atnear-zero output. When it senses a loadrequirement, the pump supplies flowand pressure to match the demand. Theresult is less hydraulic system heat andlower power consumption. Implement control valvesare designedand built by Caterpillar specifically formotor graders . They provideoutstanding operator feel andpredictable system response forunmatched implement control.

9 To helpmaintain exact blade settings, lockvalves are built into all control relief valves are also incorporatedinto selected control valves to protectthe cylinders from operator controlsare designed to reduce operator feature short lever throws and lowefforts in both directions. Properlyspaced control levers and short leverthrows allow the operator to usemultiple controls with one hand. Balanced the operator usesseveral controls at one time, flow isproportioned to ensure all implementscan operate simultaneously. If hydraulicdemand exceeds pump capacity,cylinder velocities will be reduced bythe same floatis incorporated into theblade lift control valves. Blade floatallows the blade to move freely underits own weight. By floating bothcylinders, the blade can follow thecontours of the road when removingsnow. Floating only one cylinderpermits the toe of the blade to follow ahard surface while the operator controlsthe slope with the other lift cylinder.

Rugged drawbarfeatures an A-frame, box-section designfor high strength. The bottom ismachined to provide accurateadjustment and precise blading. A one-piece forged circle is built to stand up tohigh stress loads. To resist wear, teethare induction-hardened in the criticalareas. For maximum support, the circleis secured to the drawbar by six moldboardand large throatclearance help move material morequickly and efficiently. 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.
