The six-cylinder, turbocharged engine is built for power, reliability and economy.
Proven Cat EnginesProven Cat engines feature high torque rise for excellent lugging in tough loading applications and are designed to work long hours in the most demanding job conditions.
Displacement-to-Horsepower RatioHigh displacement-to-horsepower ratio reduces stress for long engine life.
Fuel SystemDirect injection fuel system is adjustment-free, with individual injection pumps and valves.
TimingAutomatic, variable-injection timing delivers fuel as needed for maximum fuel efficiency when engine rpm varies between cut or fill work and high speed hauling.
Fuel/Air Ratio ControlFuel/air ratio control is tamper resistant. Break-off blots and seal wires protect the control from adjustments that will not meet emissions regulations.
TuborchargerTurbocharger air flow is matched with the horsepower rating for improved performance and lower emissions.
Exhaust PortsExhaust ports have stainless sleeves to reduce heat rejection, resulting in less heat transfer to the jacket water system.
Cooling JetsDual-tube cooling jets in the block provide more oil to the bottom of the piston for better cooling.
Front Engine Support GroupFront engine support group is isolation-mounted to reduce vibration transfer.
Ground-Level Engine Shutoff SwitchGround-level engine shutoff switch provides convenience and emergency access.
Thermo-ShieldLaminated Thermo-Shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, improves hose and wiring life.
Smooth, automatic shifts for top production
Eight-Speed Power Shift TransmissionEight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation. It also eliminates torque converter drive at haul road speeds above 5 mph (8km/h).
Neutral Coast Inhibitor ControlNeutral coast inhibitor control utilizes a ground speed sensor which automatically downshifts the machine to the current ground speed until torque converter drive speed is reached.
Top Gear ControlTop gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.
Directional Shift ManagementDirectional shift management reduces drivetrain stress during an aggressive directional shift.
Electronic Programmable Transmission Control (EPTC II)The Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.
Smoother ride improves productivity.
DesignCaterpillar cushion hitch design dampens shocks to provide a smoother ride. The result is higher speed capability, less machine wear and increased productivity.
Work-alone capability reduces the operating cost-per-ton.
Variable Speed ElevatorInfinitely variable speed elevator, in both forward and reverse, allows the operator to match elevator speed to material.
Ejector Bowl and SidesEjector bowl and sides have been raised, improving the load profile by providing better carrying capacity and material retention.
Comfort and control increase operator efficiency.
ROPS CabSound suppressed, rubber-mounted ROPS cab reduces sound and vibration for comfortable, shift-long operation.
Electronic Monitoring SystemThe electronic monitoring system checks important machine systems and provides a three-level alert system.
Hydraulic Servo-Steering SystemHydraulic servo-steering system provides low-effort, automotive feel and excellent maneuverability.
Telescopic Steering SystemThe telescopic steering system is height adjustable and tilts at knee level for enhanced operator comfort and easy entry and exit.
Implement ControlsPilot-operated implement controls can reduce operator fatigue by requiring a very low effort to actuate a machine function.
SeatAir suspension seat is multi-adjustable.
Radio Ready ArrangementRadio ready arrangement includes speakers, a 5-amp converter and two radio openings. A 15/25-amp converter is available from Custom Products.
Simplified service means more productive uptime.
Service FeaturesThere are many convenient service features that keep these machines on the job.
O-ring Face SealsO-ring face seals help make these machines "dry".
Hydraulic Chain AdjusterNew hydraulic chain adjuster is easily adjusted using a grease gun, reducing service time and improving overall chain life.
Centralized Lubrication BlocksCentralized lubrication blocks for the hitch and steering reduce lube time.
Service PointsService points for the engine are grouped on the righthand side for easy access.
Platforms and HandholdsService platforms and numerous handholds for easy access and safety.
Folded Core RadiatorFolded core radiator allows individual cores to be replaced as a module which reduces service time and expense.
Sealed Floor RollersSealed floor rollers eliminate lubrication.
Unmatched in the industry.

RetarderOptional retarder extends brake life when working on severe, downhill slopes.
Component CommonalityIncreased component commonality with other Cat scrapers improves parts availability.
BumpersRounded off bumpers reduce hooking into high walls.
Ground-Level Engine Shut-OffsGround-level engine shut-offs for operator convenience and emergency access.
CastingsExtensive use of castings in the frame, hitch and bowl provides long service life.
Wiring Harness and Hose AssembliesWiring harness and hose assemblies run down the draft arms to eliminate the need for "jump-over" lines which can reduce hydraulic system efficiency.
TiresStandard tires provide the maximum flotation.
Scraper Driveline GuardScraper driveline guard protects the output case, differential and ejector cylinder which can minimize driveline maintenance costs.
Laminated Thermo-ShieldLaminated Thermo-Shield helps keep surface temperatures in the engine compartment below the flash point of diesel fuel.
