  • Powerful Performance. The 3176C highperformance electronically controlleddiesel engine - with six-cylinder, directinjection, turbo-charged, air-to-air after-cooled (ATAAC), and 4-valves percylinder - delivers net power of 184 kW(246 hp) and enables the 966G II toperform in the most demanding ofapplications. The 3176C is the ultimatecombination of Caterpillar diesel andelectronic component technologyincluding ADEM III, CaterpillarMonitoring System, and ATAACresulting in unmatched productivityand efficiency.

    Advanced Fuel System. The 966G IIfeatures a Caterpillar exclusiveAdvanced Diesel Engine Module(ADEM III) fuel system controller.ADEM III controls all major enginefunctions, regulates the timing,duration, and pressure of the fuelinjection, providing this informationto the Caterpillar Monitoring System.

    Caterpillar Monitoring System (CMS).CMS monitors six major engine systemfunctions and derates the engine shouldany critical conditions occur. Timelyinformation allows operators to bettermanage machine operation and takenecessary corrective actions, lesseningthe risk of potential machine damage.

    Turbocharged and ATAAC. Turbo-charging packs dense air into thecylinders for more complete combustionand lower emissions. Air-to-air after-cooler (ATAAC) reduces smoke andemissions by providing cooler inletair for more efficient combustion.The result is high output and efficiencywhile meeting EPA Tier 2 emissionscompliance.

    Constant Net Horsepower. The 3176Celectronic engine continuously gathersinformation to control the on-demandfan speed and provide constant nethorsepower regardless of operatingconditions. Compensating for varyingfan loads enables the machine tomaintain normal system temperaturesand reduce fuel consumption.

    Less Maintenance. With the 3176C, theengine oil change interval is increasedfrom 250 to 500 hours with the useof CH-4 oil, after an initial 250 houroil change, to provide reduced costsand downtime.

    EngineThe 966G Series II engine is built for power and reliability to deliver excellent productivityand cost effective operation.

  • Electronic Power Shift Transmission.The planetary power shift transmissionwith automatic shift capability is designedand built by Caterpillar. The planetarydesign results in more gear tooth contactfor transmitting loads and durability.This robust transmission allows fullpower, speed, and directional changes.

    Electronic Clutch Pressure Control(ECPC). Input from both the transmissionand the operator controls in the cabmodulate each individual clutch througha proportional electro-hydraulic valve.Six proportional electro-hydraulicvalves pressurizing the clutches areidentical and are bolted on top of thetransmission. This results in smootherspeed and directional shifts. Energy ismodulated in the clutches, resulting inlonger component life.

    Integrated Braking System (IBS).The Caterpillar exclusive IBS integratesdownshifting and neutralizer logic intothe left-hand brake pedal. IBS increasesperformance and productivity with anoptimized transmission neutralizer andautomatic downshifting. IBS also lowersowning and operating costs by reducingaxle oil temperatures to extend brake life.

    Free Wheel Stator Torque Converter(FWSTC). FWSTC reduces drags in thetorque converter at high turbine speed/impeller speed ratios. This improvesmachine power train efficiency andcontributes to improved fuel economyin certain applications.

    Variable Shift Control (VSC). VSCtransmission software allows theoperator to select three different shiftpatterns based on the application andoperating preferences. This featurereduces fuel consumption in certainapplications. In all modes, fullmachine power remains availablefor production loading.

    Easy Service. Daily oil level check isdone from the ground through a well-protected sight gauge. An oil samplingvalve allows quick, clean access to thetransmission for SOSSM oil analysis.

    Ecology Drain. A transmission oil ecologydrain is standard and allows oil to bedrained without spillage.

    Electronic TransmissionAdvanced Caterpillar power train is reliable and fuel efficient.

  • Reversed Airflow, Unit Core Radiator.The airflow is reversed on the 966G IIand enters through the rear grill, exitsout the top and side hood panels.Reversed air flow means less debrisentering the system. In addition, a newunit core radiator with square waveshaped fins and lower fin density (6 finsper inch) allows debris to pass throughmore easily.

    Electronically Controlled On-DemandFan. Electronically controlled,temperature sensing variable speed on-demand fan adjusts to meet thevarying cooling requirements of themachine throughout the work cycle.Hydraulic oil, engine coolant, and inletmanifold temperatures determine fanspeed. In cooler operating conditions,average fan speed is reduced, resultingin less fuel consumption and lowernoise levels. Lower air flow alsoreduces cooler core plugging inhigh airborne debris applications.

    Convenient System Access. The 966G IIoffers both a swing-out grill and swing-outhydraulic oil cooler and air conditionercondenser for fast and easy cleaning.Left and right side panels also allowaccess to cores for cleaning.

    Airborne Debris Grill (Optional).An optional attachment, the airbornedebris grill replaces the standard reargrill with one that has a verticallycorrugated steel screen with 4 mm(0.16") perforations to restrict theentry of airborne debris. The grill ishinged to allow access to cooler coresfor cleaning, and also includes bracketsto seal around the fuel tank and screenmaterial between the bottom of the grilland the counterweight.

    Cooling System The 966G Series II cooling package provides reduced radiator plugging, fuel efficiency, andeasy maintenance.

  • Heavy-Duty, Four-Piece Axle Design.Caterpillar designed and built withproven durability, the 966G four-piece axle design is maintained for the966G Series II. Designed to last in alloperating conditions, each axle containstwo axle shaft housings, the centerhousing, and the intermediate housing.The front axle is fixed, and the rearaxle oscillates 13 degrees.

    Fully Hydraulic Service Brake.Inboard brakes are positioned next tothe differential operating on the lowtorque side of the final drive. Fourfriction discs, two each side, are fullyenclosed within each axle to lock outcontaminants. Multiple oil-disc brakesare adjustment free, and bathed in axleoil for excellent cooling. Independentfront and rear brake circuits use separate,heavy-duty piston-type accumulators toensure dead engine braking.

    Integrated Axle Diagnostics.

    1. Brake wear indicators (2 per axle)provide easy access to measure brakedisc wear without disassembling theaxle. The original brake reading isrecorded in the machine controls atthe factory to allow precise
