C9 Engine. The Caterpillar C9 enginemeets worldwide emissions regulationsfor the Environmental ProtectionAgency (EPA), the European Union(EU) and the Japan Ministry ofConstruction (JMOC).

• Wastegated turbochargerfor improved response.

• Extended oil change intervals.

Cylinder Liners. Mid-supportedwet cylinder liners provide excellentdurability and rebuildability.

Advanced Fuel System. The C9features an electronically controlled,hydraulically-actuated, direct injectionfuel system that provides improvedfuel economy and reduced emissions.

Cylinder Block. Engine durabilitybegins with its foundation – the engineblock. The serpentine design of the C9block provides maximum strength ina reduced weight design. It is a single-piece, deep-skirted design providing asolid base for the durability you requirein today’s D6R II.

Cylinder Head. The C9 cylinder head isdesigned for maximum breathing, whichhelps ensure excellent fuel efficiency.This one-piece, stress-relieved,gray-iron casting has four valves percylinder. Robust intake and exhaustvalves aid airflow and provide excellentreliability and fuel efficiency.

Pistons. The two-piece articulatedpiston design consists of a forged-steelcrown for maximum strength and acast aluminum skirt to reduce weight.A large piston pin holds the crown,skirt and connecting rod together.The aluminum skirt runs cooler thanconventional pistons, allowing a closerfit to the cylinder liner and providinglonger life. The steel crown handlesthe higher internal pressures oftoday’s engines.

Crankshaft. The crankshaft is a steelforging with induction-hardened journalsand fillets. The wide center and endmain journals and bearings are designedto maintain maximum oil film thicknessfor excellent lubrication and forcooling the bearings. The result islong life-to-overhaul.

EngineThe C9 engine, matched with the torque divider and field proven power shift transmission,provides years of dependable service.

Two Pass Cooling System. Using a twopass system, the AMOCS radiatorprovides a more efficient heat exchange.The coolant is routed from a sectionedbottom tank up the front side, over thetop of the core and down the engineside of the core to the bottom tank.This flow pattern allows the coolantto pass through the radiator twice forbetter cooling.

Modular Design. The cooling elementsare individual core modules connectedto a sectioned bottom tank. There is notop tank to remove.

• Standard nine steel fins per 2.54 cm(1 in), or an optional 6 steel fins per2.54 cm (1 in).

• Brass tube construction within eachcore for improved reliability.

Air-to-Air Aftercooler. The D6R IIfeatures air-to-air aftercooling.Dedicated air-to-air aftercooler circuitprovides cooler inlet air temperatures,which improves performance andreduces engine emissions.

Serviceability. Modular core designpermits removal of a single corewithout removing the entire radiator,which reduces repair costs and downtime.AMOCS eliminates the top tank,side channels and one sealing surface,making it more reliable and easier toservice. It features a site gauge forquick service checks.

Protection From Leaks. To reduce thepotential for coolant leaks, brass tubesare welded to a large, thick header,improving strength of the tube-to-headerjoint. In conditions where abrasivematerials can be airborne, use theattachment sand blast grid to preventcore damage.

Sand Blast Grid. In an application whereairborne debris is prevalent, radiatorcore protection is a concern. To extendradiator life in harsh applications, a sandblast grid is available as an option todeflect the damaging debris the enginefan propels at the radiator.

5

Advanced Modular Cooling System (AMOCS)AMOCS utilizes an exclusive two pass cooling system and increased cooling surface areato provide significantly more cooling efficiency than conventional systems.

Torque Divider. A single stage torqueconverter sends 70% of engine torquethrough a converter and 30% through adirect drive shaft for greater drivelineefficiency and higher torquemultiplication to get heavy loadsmoving. The torque divider providesimproved efficiency and broader rangeof performance in second gearapplications.

Key Benefits of a Torque Divider.The D6R II torque divider provides:

• High reliability.

• Low dynamic torque.

• Optimum combination of operatorefficiency and driveline reliability.

• Components are designed to absorbfull engine power.

Transmission. The D6R II planetarypower shift transmission features threespeeds forward and three speeds reverseand utilizes large diameter, high-capacity,oil-cooled clutches. To maximize thelife of the transmission, the planetarydesign distributes loads and stressesover multiple gears.

• Controlled throttle shifting regulatesengine speed during high energydirectional shifts for smoother, morecomfortable operation and longercomponent life.

• Electronic clutch pressure controlpermits fast speed and directionchanges.

• Modular transmission and bevelgear slide into rear case for servicingease, even with ripper installed.

• Oil-to-water cooler for maximumcooling capacity.

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

Drive TrainGet maximum power to the ground with the efficiency and reliability you expect fromCaterpillar machines.

Operating Efficiency and DrivelineReliability. The D6R II torque dividerattains the best combination ofoperating efficiency and drivelinereliability. It reduces dozing shockloads to the transmission and finaldrives by acting as a hydrodynamiccomponent between the engine andtransmission.

Finger Tip Control. The D6R II withFinger Tip Control features low effortfinger tip levers for steering and touchshift buttons for upshift and downshift.The steering clutches and brakes arefade resistant and adjustment free.Multi-disk, oil-cooled steeringclutches are hydraulically applied andelectronically controlled. Brakes areapplied by springs and hydraulicallyreleased for safe, reliable brakingperformance.

Differential Steering. A D6R II equippedwith differential steering maintainspower to both tracks while turning.The tractor turns when one track speedsup and the other slows down an equalamount. The operator can steer andcontrol the transmission simultaneouslywhich can reduce cycle times in someapplications. The differential steeringtiller bar has touch shift buttons forupshifts and downshifts. The tiller baritself is easily rotated forward or reverseto change the respective tractor direction.The tiller bar is moved forward to steerthe tractor to the left and pulled backto go right. Low tiller bar efforts assureoperator comfort during long shifts.Large blade loads can be maneuveredaround buildings, bridge abutments,trees, or other obstacles. Steeringmodulation is also optimized for precisecontrol in these applications. Greaterload capacity, power and speed controlare possible in soft underfoot conditionsand on steep slopes because both tracksare powered during turns.

Elevated Final Drive. Isolates finaldrives from ground and work toolinduced impact loads for extendedpower train life.

Thick, Large Diameter Plates andClutch Disks. Provides higher torquecapacity and increased service life.

Auto-Shift/Auto-Kickdown. Auto-shiftallows the operator to pre-select aforward and reverse gear for easy,efficient directional changes. Auto-shiftsettings include first forward to secondreverse, second forward to secondreverse and second forward to firstreverse. Auto-kickdown allowsthe transmission to automaticallydownshift when significant loadincreases are detected.

Load Compensating Shifting.Automatically adjusts the clutchengagement timing according to loadfactor, resulting in improved tractorperformance and operator comfortduring speed changes. Load compensatingshifting reduces the amount of energydissipated through the clutches to helpextend transmission component life.
