Sampling valves andecology drains help prevent fluid spills.pg. 7✔ Powerful Performance. The 3126BATAAC engine delivers net power of119 kW (160 hp), and meets EPA Tier 2emissions standards. Its advanced fuelsystem keeps fuel at low pressure in thelines until it is injected into the cylinder.Fuel pressure is created hydraulically inresponse to a signal from the ADEM IIIElectronic Control Module.Electronic Control Module. The AdvancedDiesel Engine Module (ADEM III)fuel system is a proprietary electroniccontrol module, which providesimproved engine response and fuelefficiency, plus advanced diagnosticsand reduced emissions. Altitudecapability is increased to 3050 meters(10,000 feet) without derating.ADEM III allows full electronicintegration of the engine and transmissionfor maximum power train efficiency.Turbocharged, ATAAC. Turbochargingpacks dense air into the cylinders formore complete combustion and loweremissions. Air-to-air aftercooling(ATAAC) provides a separate coolingsystem for intake manifold air. TheATAAC system reduces smoke andemissions by providing cooler inlet airfor more efficient combustion.Constant Net Horsepower. The 938G II’selectronic engine is integrated with anon-demand cooling fan. The enginecompensates for varying fan loads andprovides constant net horsepower,regardless of operating conditions.A consistent level of “working”horsepower is provided and fuelconsumption is reduced.Oil Change Intervals. The engineoil change interval is increased to500 hours (with CH-4 oil), reducingcosts and downtime.4EngineThe 938G II provides more power, excellent fuel economy, and reduced maintenance. Electronic Power Shift Transmission.The electronic power shift transmissionwith automatic shift capability is acountershaft design built by Caterpillar.It is electronically controlled and allowsfull power shifts and directionalchanges. Fully modulated gear shiftscontribute to operator comfort andincrease component life.Electronic Clutch Pressure Control(ECPC). Senses input from both thetransmission and the operator controlsin the cab to modulate each individualclutch through a proportional electro-hydraulic valve. This results in smoothergear changes and improved shiftquality. Energy is modulated into theclutches, resulting in longer clutch life.Integrated Braking System. New forG Series II, IBS integrates downshiftingand transmission neutralization into theleft-hand brake pedal. IBS providessmooth, optimized transmissionneutralizer performance with a greaterrange of adjustability. The IntegratedBraking System also lowers owning andoperating costs by reducing axleoil temperatures, which can extendservice brake life.Easy Service. Daily transmission oillevel check is done from the groundthrough a well-protected sight gauge.An oil sampling valve allows quick,clean access to the transmission forS•O•SSMoil analysis.Variable Shift Control. New transmissionfeature which allows the operator toselect one of three different shift patternsbased on the application and operatingpreferences. VSC reduces fuelconsumption in many applications.In all modes, full machine powerremains available for loading.Traction Control System. The Caterpillarexclusive Traction Control Systemtraction aid (attachment) has beenimproved for G Series II. Sensors andconnectors have been upgraded forlonger life. A new lighted cab switchindicates when the TCS system is “on”.The Traction Control System measuresaxle shaft rotation and vehicle articulation.When a tire slips in poor underfootconditions the system applies theservice brake and torque is transferredthrough the differential to the oppositeside wheel with better traction. TCS isfully automatic, works on all four wheelsindependently and combines themaneuverability of an open differentialwith the power of a limited slip.5Power TrainAdvanced Caterpillar power train is reliable and fuel efficient. Reverse Flow. Air enters through therear grill and exits out the top openingand side hood doors. Rear air flow picksup less debris from the ground, reducingplugging.Improved System Access. The 938G IIadds a swing-out grill, hydraulic oilcooler and air conditioner condenserfor easier cleaning. Side panels open toallow access to both sides of all coresfor cleaning. A heavy duty AirborneDebris Grill, with 4 mm perforationsis available as an attachment.On-Demand Fan. Electronicallycontrolled, variable speed on-demandfan adjusts to meet the varying coolingrequirements of the machine. Fan speedis determined by oil, coolant and inletmanifold temperatures. In cooleroperating conditions, average fanspeed is reduced, resulting in less fuelconsumption, lower noise levels andless radiator plugging.Unit Core Radiator. New unit coreradiator with square wave shaped fins.Lower fin density (6 fins per inch) allowsdebris to pass through more easily.6Cooling SystemNew G Series II cooling package reduces radiator plugging and improves fuel efficiency. Low Exhaust Emissions. The Cat 3126BATAAC engine used in the 938G Series IIis a low emission engine designed tomeet Tier 2 emission regulations. It iselectronically controlled, with air-to-airaftercooling for more efficientcombustion and cleaner emissions.Reduced Sound. The electronicon-demand fan automaticallyregulates fan speed depending oncooling requirements. The fan drawsless horsepower in cooler ambienttemperatures, which reduces fuelconsumption. Sound levels are alsoreduced when the fan slows down.There is additional insulation aroundthe engine to reduce sound levels.Environmental Fluids. Extended LifeCoolant/Antifreeze with anti-foamingand anti-corrosion properties provideextended service intervals (up to6000 hours) and requires less frequentfluid changes and disposals. Airconditioning refrigerant is CFC-free.Fewer Leaks And Spills. Oil samplingvalves and pressure test ports areincluded for easy service diagnostics,with less chance of spills. Filters arepositioned vertically and located foreasy access, allowing for removalwithout fluid spillage.Ecology Drains. Standard for the engine,transmission, hydraulics, radiator andfuel. Activating the valve allows fluidto be drained into a container withoutspillage. Axle oil ecology drains arean attachment and allow quicker oilchanges with reduced spillage.Rebuildable Components. Many majorcomponents are designed to be rebuilt.Worn components can be remanufacturedinstead of thrown out.7Environmental FeaturesCaterpillar cares about the environment and continues to develop innovative solutions. 12345678910 11128The ultimate in wheel loader operator comfort and efficiency.Operator Station 1 Steering.
