Cat 3176C Engine. The Cat 3176C enginemeets EPA Tier 2, EU Stage II, andJapan MOC Step 2 exhaust emissionregulations. Major features include:

• Power of 179 kW (240 hp) forsuperior performance.

• Large displacement electronicengine with lower exhaust emissionsand good cold start capability.

• Power train to engine link withcontrolled throttle shifting.

• Higher efficiency turbochargerfor improved airflow.

• Fuel/Air Ratio Control to minimizeacceleration smoke.

Cylinder Block. Engine durability beginswith its foundation – the engine block.The serpentine design of the 3176Cblock provides maximum strength withreduced weight. A single-piece, deep-skirted design provides a solid base forthe durability you require in today’s572R Series 2.

Electronic Unit Injector (EUI). Themechanically actuated, electronicallycontrolled unit injector combines anelectronic actuator, pump assembly andnozzle into a single, compact unit forreliability and durability. The 3176Cfuel system has been tested in thousandsof engines in some of the most demandingapplications and environments aroundthe world.

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 steelforging with induction-hardenedjournals and fillets. The wide centerand end main journals and bearings aredesigned to maintain maximum oil filmthickness for excellent lubrication andfor cooling the bearings. The result islong life-to-overhaul.

Power Train The 3176C engine, matched with the torque divider and field proven power shifttransmission, provides years of dependable service.

Two-Pass Cooling System. Using a two-pass system, the AMOCS radiatorprovides a more efficient heat exchange.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.

Design includes:

• Standard 9 steel fins per 2.54 cm(1 in), or an optional 6 steel finsper 2.54 cm (1 in).

• Brass tube construction within eachcore for improved reliability.

Separate Circuit Aftercooling.The 572R Series 2 features a SeparateCircuit Aftercooler. Two of the AMOCScores are dedicated to the aftercoolercoolant circuit to achieve cooler inletair temperatures, which increasesperformance and improves engineemissions. A separate water pump isused to circulate the aftercooler coolant.

Serviceability. Modular core designpermits removal of a single core withoutremoving the entire radiator, reducingrepair costs and downtime. AMOCSeliminates the top tank, side channelsand one sealing surface, making itmore reliable and easier to service.Also features a site gauge for quickservice checks.

Protection From Leaks. To reduce thepotential for coolant leaks, brass tubesare welded to a large, thick header,improving strength of the tube-to-header joint. In conditions whereabrasive materials can be airborne,the attachment sand blast grid shouldbe used to inhibit core damage.

Sand Blast Grid. In applications 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.

Operating Efficiency and DrivelineReliability. The 572R Series 2 torquedivider attains the best combinationof operating efficiency and drivelinereliability. Reduces shock loads to thetransmission and final drives by actingas a hydrodynamic component betweenthe engine and transmission.

Transmission. The proven 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 smootheroperation and longer component life.

• The transmission and bevel gear setare modular by design and easilyslide into the machine’s rear case.

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