Mechanical PartsFewer mechanical parts in the fuel system improves reliability.
Electronic ControlElectronic control provides automatic altitude deration and automatic air filter restriction deration.
Multiple Horsepower RatingsMultiple horsepower ratings limit output in first and second gears unless the operator has the auger or elevator engaged.
Neutral Start ControlNeutral start control prevents engine from starting unless transmission is in neutral.
Throttle Back-upThrottle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.
Directional Shift ManagementDirectional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.
Controlled Throttle ShiftingControlled throttle shifting increases drivetrain life by reducing the fuel injection rate just prior to shifting.
Automatic Ether Starting AidAutomatic ether starting aid greatly improves cold weather starting.
Electronic Ground Level ShutoffElectronic ground level shutoff enables the operator to stop the engine from the ground with the flip of a switch.
Steel Spacer PlateSteel spacer plate between the block and head eliminates the need for counterbores and helps prevent associated cracking problems.
Oil-Cooled PistonsOil-cooled pistons and full-length water-cooled cylinder liners provide maximum heat transfer for longer component life.
AftercoolerThe aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.
Engine Oil CoolerEngine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.
Laminated Thermo-ShieldLaminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.
Optional RetarderThe optional retarder can extend brake life.
TransmissionEight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.
Neutral Coast Inhibitor ControlNeutral coast inhibitor control helps prevent the transmission from shifting to neutral at speeds above 8.1 km/h (5 mph).
Top Gear ControlTop gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.
Electronic Programmable Transmission Control (EPTC II)Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.
Electronically Controlled Cushion Hitch
Smoother ride improves productivity.
DesignThe Caterpillar electronically controlled cushion hitch design dampens shocks to provide a smoother ride.
Nitrogen AccumulatorsNitrogen-over-oil accumulators absorb and dampen road shocks.
Cushion Hitch LockElectronically controlled cushion hitch locks down for positive control of the cutting edge during loading and dumping.
Double Kingbolt DesignDouble kingbolt design withstands high external forces and allows easy installation and removal.
Hitch CastingsExtensive use of steel castings eliminates many welded joints, making a strong hitch.
Low, wide, large-capacity design boosts production.
EdgeWide cutting edge scoops large volume loads from shallow cuts, while the low-profile design of the bowl offers less resistance to incoming materials.
ConstructionCellular construction adds strength and dent resistance to bowl sides and floor.
Steel RouterSteel router and edge supports, floor plates and high-abuse components are tempered for strength.
Bulldozer Ejection systemCat bulldozer ejection system combines constant spreading control with bowl-cleaning efficiency.
Angled Top PlateAngled top plate on ejector helps retain load.
Auger MechanismAn auger mechanism in the bowl improves self-loading capabilities by lifting material off of the cutting edge and carrying it to the top of the load.
Comfort and control increase operator efficiency.
CabStandard rubber-mounted cab reduces noise and vibration for comfortable, shift-long operation.
ControlsLow-effort controls are easily accessible for sure, precise operation.
SteeringHydraulic servo-steering system provides low-effort automotive feel and excellent maneuverability.
Steering ColumnTilt steering column adjusts to five different positions for operator comfort and control.
SeatA suspension seat delivers a comfortable ride.
Electronic Monitoring SystemThe Electronic Monitoring System checks important machine systems and provides a three-level warning.
RadioThe operator's station includes radio compatible wires in the cab.
Multifunction Bowl LeverMultifunction bowl lever gives operators the ability to control important scraper functions without removing their hands from the bowl lever.
Engine Overspeed Indicator LightEngine overspeed indicator light and alarm sound when the engine rpm exceeds 2700.
Simplified service means more productive uptime.
Fuel TankScraper-mounted fuel tank improves access to tractor engine compartment.
Wiring HarnessImproved wiring harness incorporates color coded and numbered circuits for quick identification, minimum 10-amp fuses and improved connectors.
Diagnostic ConnectorDiagnostic connector, with the aid of a service tool, allows quick analysis of the starting and charging circuits.
O-Ring Face SealsO-ring face seals help keep these machines 'dry'.
Centralized Lubrication BlocksCentralized lubrication blocks for the hitch and steering reduce lube time.
Service PointsService points for the engine are grouped on the right side for easy access.
Service PlatformsService platforms and numerous handholds improve access and safety.
Parts AvailabilityIncreased component commonality with other Caterpillar scrapers/machines improves parts availability.
Engine Shut-offsElectronic ground-level engine shut-offs for convenient operator and services areas.
Cat is committed to provide the most dependable machines on the market.
Optional RetarderThe optional retarder extends brake life when working on severe, downhill slopes.
CastingsExtensive use of castings in the frame, hitch and bowl provide long service life.
Wiring Harness and Hose AssembliesWiring harness and hose assemblies run down the draft arms to eliminate the need for "jump-over" line which can reduce hydraulic system efficiency.
TiresStandard tires provide the maximum flotation of the available options.
Scraper Driveline GuardScraper driveline guard protects the output case, differential and ejector cylinder to help minimize driveline maintenance costs.
Laminated Thermo-ShieldLaminated Thermo-Shield helps keep surface temperatures in the engine compartment below the flash point of diesel fuel.
