Benefits & Features
Overview
Engineered for demanding work.
The D6R's durable construction is made for tough working conditions. It keeps material moving with the reliability and low operating costs you expect from Cat machines.
Power Train
Turbocharged 3306 Diesel Engine
Turbocharged 3306 diesel engine delivers plenty of power for quick response and big loads.
Large Displacement
The 3306 has large displacement, high torque rise and low rpm rating for low stress, long life.
High Torque Rise
High torque rise offers superior lugging capabilities to keep moving through tough spots without downshifting.
Direct Fuel Injection
Direct fuel injection precisely meters fuel for maximum productivity per unit of fuel.
Good Weight-To-Horsepower Ratio
Good weight-to-horsepower ratio allows faster loading, bigger loads and shorter cycle times.
Planetary Powershift Transmission
Planetary powershift transmission has 3-speeds forward and 3-speeds reverse and utilizes large diameter, high-capacity, oil-cooled clutches.
Torque Divider
Torque Converter
The torque converter shields the driveline from sudden torque shocks.
Cooling System
Advanced Modular Cooling System
Advanced Modular Cooling System (AMOCS) utilizes an exclusive two pass cooling system and increased cooling surface to provide a more efficient heat transfer system than conventional systems.
Two Pass Cooling System
Two 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.
Caterpillar Extended Life Coolant
Caterpillar Extended Life Coolant is now standard in all D6R tractors. This coolant can double the Cat engine coolant life and allow for longer intervals between coolant changes when Cat extender solution is used at 3000 hours.
Cooling Elements
The cooling elements are individual core modules that are connected to a sectioned bottom tank. There are nine steel fins per inch, brass tube construction within each core and no top tank to remove.
Servicing AMOCS
The servicing of the AMOCS can be performed without tilting the radiator guard. There is no need to remove or replace a major component as on single core radiators. Each core module can be replaced individually, saving considerable cost and repair time.
Undercarriage
Final Drives
Final drives and associated power train components are raised above the work area - isolating them from ground-induced impact loads, as well as implement and roller frame alignment loads - extending power train component life.
Sprocket Position
The sprocket position keeps sprocket teeth, bushings and final drives away from the abrasive materials and moisture - resulting in longer final drive gear and seal life.
Heavy-Duty Sealed and Lubricated Track
The heavy-duty sealed and lubricated track is designed for superior track life. A wider bushing strap provides improved bushing retention and resistance to bore stretching and cracking.
High Flange Improved Track Rollers
High flange improved track rollers (optional) combined with center or full length roller guard attachments greatly improve track guiding for demanding side slope or impact conditions.
Rotating Bushing Track
Rotating bushing track (optional) is a sealed and lubricated system which includes four track seals per joint, non-restrained floating bushings, longer track pins, redesigned track links and a unique pin retention system.
Built to Excel
The XR undercarriage is built to excel in drawbar, skidding, and ripping applications.
Heavy-Duty Track Link
Heavy-duty track link is standard on all D6R configurations.
Work Tools
Blades
Choose from the S, SU or A blade for optimum production.
Ripper
The multi-shank parallelogram ripper lets you choose up to three shanks, depending on job conditions.
Winch
A single lever control actuates both clutch and brake functions to improve operator efficiency. A separate lever is used for freespool operation.
Load Sensing Hydraulics
Hydraulic Power Requirements Continually Monitored
Load-sensing hydraulics utilize a feedback loop from the attachment valve to the attachment pump to continually monitor the hydraulic power requirements of the implement.
Lower Pump Requirements
Lower pump requirements can reduce engine power requirements for the hydraulics, making more drawbar power available for increased machine production, higher operator efficiency and increased fuel efficiency.
Operator's Station
Operator Station Design
The operator's station provides excellent viewing area to the blade and rear of machine for maximum operator productivity.
Easy-To-Reach, Low-Effort Controls
Easy-to-reach, low-effort controls provide sure, precise steering and dozer control for less operator fatigue.
Isolation-Mounted Cab
Isolation-mounted cab (optional) with air pressurizer and heater reduces noise and vibration for shift-long comfort.
Caterpillar Contour Series Seat
The Caterpillar Contour Series Seat is ergonomically designed and fully adjustable for maximum comfort.
Radio Installation Group
The radio installation group is standard in the D6R cab. It includes mounting brackets, AM/FM antenna and speakers.
Sound Levels
Sound levels have been reduced.
Other Improvements
Other improvements include enlarged storage compartments for personal items, a cupholder, adjustable armrests, kneepads for side slope operations and window slides providing better sealing.
Steering
Differential Steering
Differential steering maintains uninterrupted power to both tracks during turns through a hydraulically actuated planetary differential, and allows simultaneous one-hand steering and transmission control.
Finger Tip Control
Finger Tip Control allows simultaneous, one-hand steering and transmission control.
Automatic Shifting
Automatic shifting features and easier upshifts and downshifts increase operator productivity, reduce fatigue, and shorten cycle times.
Serviceability
Major Components
Major components are easily accessible and removable as single units.
Modular Design
The modular design permits fast removal and installation.
Pre-Testing of Modular Components
Pre-testing of modular components before installation or after repair assures quality.
Grouped Service Points
Grouped service points allow easy access to service areas and make routine checks fast and convenient.
Diagnostic Connector
A diagnostic connector for a special dealer tool enables fast troubleshooting of tractor systems.
Quick, Easy Service Access
The D6R design allows quick, easy service access and inspection.
Ecology Drains
Ecology drains provide an environmentally safer method to drain fluids. They are included on the radiator, engine and hydraulic tank; optional for the transmission, bevel gear case and torque divider.
