3306 Diesel Engine. The Caterpillar 3306is a six-cylinder, four stroke diesel.The large displacement allows lowerengine speeds for reduced stresses andincreased engine life.

Direct Injection. The 3306 maintainsgood productivity per unit of fuel burnedby using direct injection to control fuelconsumption. Optimum weight-to-horsepower ratios minimize cycle times,allow larger blade loads and shorterload times.

Injector nozzles are non-clogging andadjustment free.

Aluminum Pistons. The 3306 featurescam-ground three-ring cast taperedaluminum alloy pistons used to reducefriction, decrease heat build-up andprovide excellent oil control. Crankcasejournals are hardened and aluminumbearings are steel-backed. The highfatigue aluminum alloy-bearings surfacenot only has the capability to withstandheavy shock loads during crankshaftrotation, it will also adapt to normalwear of the crankshaft journals.Valves. Valves are stellite face hardenedwith hard alloy steel seats for hardnessthat contributes to long service life.

Rebuildability. The 3306 has the abilityto be rebuilt to provide long andreliable life.

EngineThe Cat 3306 uses direct injection to control fuel consumption and allows lower enginespeeds for reduced stresses and increased life.

Torque Divider. The torque dividerarrangement is a Caterpillar exclusivethat provides high torque multiplicationwhen under load with direct driveefficiency when completing lowerengine load functions such as backfillingtrenches or spreading material.

Power Shift Transmission. Three speedsforward and three speeds reverse,utilizing large diameter, high capacity,oil-cooled clutches.

Modulation system permits fastspeed and direction changes.

Oil-to-water cooler for maximumcooling capacity.

Forced oil flow lubricates and coolsclutch packs to provide maximumclutch life.

5

Power TrainWith a power train that is designed and built by Caterpillar, the D6G Series 2 ensurescompatibility, maximum performance and reliability.

Roller Frames. The track roller frameis a reinforced box section constructionwith seven lifetime lubricated trackrollers per side and outside mountedcarrier rollers, two per side.

Rollers and Idlers. Feature symmetricDuo-Cone seals for long sealing life toprevent oil loss and dirt entry. Toric ringsmaintain performance over a wide rangeof temperatures. Rollers and idlers arelifetime lubricated, serviceable andrebuildable to provide value. Abutment-style caps securely attach rollers andidlers to the bogies.

All idlers, track and carrier rollersare life-time lubricated and requireno periodic maintenance intervals.

Track Shoes. Track shoes are availablein sizes to match the working conditions.

Guards. Front and rear guiding guardsare standard.

Sealed and Lubricated Track.Minimizes internal bushing wear withthe pin by a thin film of lubricantand retained by a polyurethane seal.Extends service life of the undercarriageas a system.

UndercarriageThe Caterpillar undercarriage is designed for optimized machine balance and best possibleperformance and component life.

Bulldozers. All blades feature astrongbox-section design that resiststwisting and cracking. Blades are madeof Cat DH-2 steel that has high tensilestrength and stands up to the mostsevere applications. Heavy moldboardconstruction and hardened bolt-oncutting edges and end bits add strengthand durability.

Straight Blade. The straight bladecan handle a wide variety of materialsincluding heavy material. With the highkW per meter (hp/ft) of cutting edge,aggressive penetration is achieved.

Angle Blade. The angle blade can bepositioned straight or angled 25 degreesto either side making this blade aversatile option.

Semi-Universal Blade. The Semi-Universal blade is built for toughapplications where penetration is moreimportant than capacity. The bladewings are designed for superior loadretention and penetration in tightlypacked materials and for finishingapplications.

Multi-Shank Ripper. Multi-shankrippers are made to penetrate toughmaterial fast and rip thoroughly for usein a variety of materials.

Cutting Edges and End Bits. Cutting edgesare made of DH-2 steel. End bits aremade of DH-3 steel to providemaximum service life in tough materials.

8The operator station is designed with optimum comfort and maximum productivity in mind.Operator Station

Directional Controls. Steering andtransmission controls are locatedconveniently to the operators leftfor comfortable operation.

Dozer Blade Controls. The dozercontrols are located on the operatorsright hand side.

Walk Through Operator Area.The operator area has a walk throughdesign providing a comfortable operatingenvironment with the controls withineasy reach.

Seat. A comfortable suspension seat isable to be adjusted fore and aft for greateroperator comfort. Arm rests also helpprovide comfort for all day operation.Wide 76 mm (3 in) seat belt is standard.

Monitoring System. A machinemonitoring system lets you track thefollowing machine systems:

Fuel level

Coolant temperature

Transmission/torque convertertemperature

Service hour meter

Air cleaner service indicator

Engine oil pressure and alternatorare monitored by a warning lampand audible alarm system.

Brake Pedal. A single brake pedalactuates both tracks to makeoperation easier.

Air Conditioner. An optional airconditioner with strategic vents providea comfortable environment in a varietyof weather conditions.

Cab. The optional cab is pressurizedto keep dust out. A 3 speed blower fanis standard.

9

Serviceability. Minimizes maintenanceand repair downtime. Large openingson either side of the machine makemajor service points easily accessible.

Machine Selection. Make detailedcomparisons of the machines you areconsidering before you buy. How longdo components last? What is the costof preventive maintenance? What is thetrue cost of lost production? Your CatDealer can give you answers to thesevery important questions.

Purchase. Consider the financingoptions available as well as day-to-dayoperating costs. This is also the timeto look at dealer services that can beincluded in the cost of the machine toyield lower equipment owning andoperating costs over the long run.

Product Support. Plan for effectivemaintenance before buying equipment.Choose from your dealers wide rangeof maintenance services at the time youpurchase your machine. Programs suchas Custom Track Service (CTS), SOSanalysis, Technical Analysis andguaranteed maintenance contractsgive peak life and performance toyour machine.

Parts Program. You will find nearlyall parts at your dealer parts counter.Cat Dealers use a world-wide computernetwork to find in-stock parts to minimizemachine downtime. Ask about yourCat Dealers exchange program formajor components. This can shortenrepair time and lower costs.

Remanufactured Components. GenuineCat Remanufactured parts save youmoney. You receive the same warrantyand reliability as new products at costsavings to further reduce operatingcosts. Components are available forthe drive train, engine, and hydraulics.

Operation. Improving operatingtechniques can boost your profits.Your Cat Dealer has training videotapes,literature, and other ideas to help youincrease productivity.
