1 The Cat 3508B Diesel Engineis a four-stroke design and useslong, effective power strokes formore complete fuel combustion andoptimum efficiency. The 3508B isdesigned with large displacementand a low speed rating for longhours of service between scheduledoverhauls and lower operating costs.

■ The 30 percent torque riseprovides high lugging forceduring dozing and acceleration inhigh rimpull conditions. Thetorque curve effectively matchesthe transmission shift points toprovide maximum efficiency andfaster cycle times.

■ Electronic Unit Injection (EUI) isa proven high-pressure, directinjection fuel system thatelectronically monitors operatordemands and sensor inputs tooptimize engine performance.

■ Advanced Diesel EngineManagement (ADEM) systemcontrols the fuel injectorsolenoids to start and stop fuelinjection. This system providesautomatic altitude compensation,air filter restriction indication,and will not allow the engine tofire until it has oil pressure,acting as a cold start protectionand a form of pre-lube.

2 Separate engine cooling systemisolates the radiator and fan from theengine compartment providinglower sound levels, more efficientcooling and a sloped hood forincreased viewing.

■ Advanced Modular CoolingSystem (AMOCS) improvescooling capabilities by usinga parallel flow system with 16cores. Serviceability is improvedwith AMOCS as there is no toptank to remove and the radiatorguard does not have to be tilted toremove the cores.

■ Separate Circuit Aftercooling(SCAC) dedicates six of theradiator’s cores to theindependent aftercooler circuit.This allows the aftercooler circuitto operate cooler resulting indenser air charge and improvedemissions.

3 Caterpillar planetary, power shifttransmission features perimeter-mounted, large diameter clutchpacks that control inertia for smoothshifting and increased componentlife. The electronically controlledtransmission enhances productivity,durability and serviceability.

■ Rimpull Control System (RCS)allows the operator to select fromfour preset maximum rimpullsettings available in first gearsettings (80,65,50 and 35percent).

■ The torque converter is equippedwith a lockup clutch for directdrive efficiency in second andthird gear.

5 Heavy-duty Axles feature standardaxle oil coolers, permanently lubeduniversal joints and stronger axlecomponents in both the differentialsand final drives for increasedperformance, serviceability anddurability.

■ Free floating axle shafts can beremoved independent of thewheels and planetaries for quickand easy serviceability.

■ Axle oil cooling system circulatesoil from the brakes anddifferentials through an oil-to-aircooler providing increased oil lifewhile extending componentperformance and durability.

6 Oil-enclosed, multiple-disc brakesare adjustment free with fewer partsfor improved serviceability. Fullyhydraulic actuators withindependent front and rear circuitsuse separate accumulators and newvalves for increased performanceand reliability.

■ Location of the brakes improvesserviceability. The axle-shaftbrake design allows brake servicewhile leaving the final driveintact.

■ Axle-shaft brakes require lessforce by operating on the lowtorque side of the axle. Combinedwith improved axle oil circulationfor increased cooling, the oil-enclosed, multiple-disc brakedesign improves durability.

4 Impeller Clutch Torque Converter(ICTC) combined with the RimpullControl System (RCS) allows theoperator maximum flexibility inmodulating rimpull.

■ The impeller clutch torqueconvertor uses the left brakepedal to modulate rimpull from100 to 20 percent for reduced tireslippage. After 20 percent isachieved, further pedal travelapplies the brake.

Structures are designed to helpimprove visibility, stability, bladecapacity and durability, without addingweight to the machine. These featuresprovide the strength expected inCaterpillar structures.

Castings in the engine-end frame areused in critical high-stress areas to helpspread the load and reduce the numberof parts. The casting for the reartrunnion mount also serves as an enginemount, which provides a load path forthe weight and torque of the engine totravel down to the trunnion and then onthrough to the axle. Other castings usedin the engine-end frame include: fronttrunnion mounts, steering cylinderbrackets, articulation stops and locklink.

1 Full box-section rear frame absorbsshock loads and twisting forcessolidly, supporting the driveline forrigid component alignment. Theframe is now extended furtherforward, which improves rail to hitchstrength.

2 Heavy-duty, box-section front frameprovides maximum structural strengthto resist twisting loads experiencedduring dozing.

3 Upper and lower hitch pins pivot ondouble-tapered roller bearings and areshaped to direct stress away from theend of the weld, resulting in asmoother transition of stress loads.The hitch is open for access.

4 Spread-hitch design helps square upthe frame and provides moreclearance for hydraulic lines. Doubletapered roller bearings and hardenedpins resist both horizontal andvertical loads to increase life. Thespread-hitch also makes serviceaccess easier.

Engine and transmission mounts aredesigned to use mushroom and cup-shaped ISO mounts, reducingcomponent vibration and sound levels.The engine mounts directly to the rearcross member, simplifying andimproving load transfer structure.
