Exchange ProgramCat dealer's exchange program for major engine components can cut repair time and costs.
Torque DividerA single-stage torque converter with output torque divider send 75% of engine torque through the converter and 25% through a direct drive shaft for greater driveline efficiency and higher torque multiplication.
Torque ConverterThe torque converter shields the driveline from sudden torque shocks and vibration.
Final DrivesElevated final drives are isolated from ground and implement induced impact loads for extended power train life.
TransmissionPlanetary power shift transmission has 3-speeds forward and 3-speeds reverse and utilizes large diameter, high-capacity, oil-cooled clutches.
The D10R combines power and efficiency with advanced technology for outstanding production at lower cost-per-yard.
Engine/Power Train Integration
Combining the electronic engine control with the Caterpillar electronic transmission control allows these critical power train components to work more intelligently.
PerformanceBy communicating, these components work to optimize overall power train performance, reliability and component life for reduced power train operating cost.
Cat Data LinkThe Cat data link electronically connects the engine and transmission control to provide these benefits.
Improved Diagnostics/ServiceabilityThe electronic engine and transmission controls provide enhanced diagnostic capability.
Superior cooling in the most demanding work conditions.
Cooling CapacityAdvanced Modular Cooling System (AMOCS) utilizes an exclusive two pass cooling system and increased cooling surface area to provide significantly more cooling capacity than conventional systems.
ServicingThe servicing of the AMOCS can be performed without tilting the radiator guard.
CirculationTwo pass cooling system circulates coolant from the sectioned bottom tank up through one side of the cooling element and down through the other side returning it to the bottom tank.
Cooling ElementsThe cooling elements are individual core modules that are connected to a sectioned bottom tank.
Demand Control FanEngine Control Module (ECM) regulates engine fan speed through a multi-disc fan clutch.
Designed for comfort and ease of operation.
ViewClear panoramic view.
OperationComfortable, non-tiring operation.
ControlsLow effort Finger Tip Controls (FTC) controls are easily accessible and provide sure, precise maneuvering with enhanced operator comfort.
SeatThe Caterpillar Contour Series Seat is fully adjustable and designed for comfort and support.
Monitoring SystemCaterpillar D10R Monitoring System has 3 display sections.
ThrottleThrottle rocker switch replaces the throttle lever, simplifying operation.
Implement Control Lever RestraintsImplement control lever restraints, when engaged, prevent inadvertent movement of control lever.
ThrottleA rocker switch replaces the throttle lever, simplifying operation.
Electronic Steering and Transmission Controls
Combines steering, machine direction and gear selection into a control system which can be operated with one hand for enhanced operator comfort and increased productivity.
Finger Tip Controls (FTC)Finger Tip Controls (FTC) are clustered for easy, one-handed operation to the operator's left.
SteeringElectronic Clutch and Brake (ECB) steering system consists of two small levers which send signals that control the steering valve.
Allows Precise WorkECB System allows the operator to work more precisely in close areas, around structures, obstacles, grade stakes, other machines or on fine grades.
Operator ComfortAdjustable operator comfort.
Machine DirectionMachine direction is controlled by a pivoting knob which can be actuated by the thumb of the left hand.
Gear SelectionGear selection is made by two buttons to the right of the machine direction knob.
Parking BrakeParking brake switch electronically locks ECB system.
Engineered to provide durability and the solid support necessary for maximum production and service life.
MainframeMainframe strength. The D10R mainframe is built to absorb high impact shock loads and twisting forces.
Frame RailsFrame rails are full box section, designed to keep components rigidly aligned.
Steel CastingsHeavy steel castings give added strength to the main case, equalizer bar saddle, front cross member and tag-link trunnion.
DurabilityThe top and bottom rails are continuous rolled sections, with no machining or welding to provide superior mainframe durability.
Final DrivesThe main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
Track Roller Frame AlignmentA pivot shaft and pinned equalizer bar maintain track roller frame alignment.
Tag-link ConstructionTag-link construction brings the blade closer to the machine for more precise dozing and load control.
Tag-link DesignTag-link design provides solid lateral stability and better cylinder positions for constant pryout independent of blade height.
The Caterpillar elevated sprockets are designed for better machine balance and component life.
DesignSuspended undercarriage design absorbs impact loads to reduce the shock loads transferred to the undercarriage.
SuspensionBogie suspension conforms more closely to the ground to provide more ground contact, especially in hard, uneven terrain.
Roller FramesRoller frames are tubular, to resist bending and twisting, with added reinforcement where operating loads are the highest.
TrackSealed and lubricated track. Permanently coats the track pin with a sealed-in lubricant, minimizing metal-to-metal contact.
