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.
An exclusive Caterpillar designed torque divider allows the engine to respond quickly to varying workloads.
The torque converter shields the driveline from sudden torque shocks.
Superior cooling in the most demanding work conditions.
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 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.
The Caterpillar elevated sprocket undercarriage arrangements allow optimized balance for the best possible performance in each application.
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.Applications
The LGP undercarriage is designed to work in soft and spongy conditions.Heavy-Duty Track Link
Heavy-duty track link is standard on all D6R configurations.
Minimizing build-up helps prevent component damage.
The elevated sprocket keeps final drives out of trash and eliminates impact loading for increased power train life.Extra Guarding
Extra guarding on final drives and idler seals prevents trash wrap-around from damaging final drive components.Larger Blade
Larger capacity landfill blade for increased trash handling capacity.Quick Access
Quick release radiator guard doors and engine enclosure doors allow quick access to engine compartment for cleaning.Striker Bars
Front and rear striker bars stop trash from damaging fenders, fuel tanks and hydraulic tanks.Additional Arrangements
Additional waste handling arrangement items are available from the Caterpillar Custom Product Group. [Refer to AEHQ5239(3/97)]
Caterpillar work tools include a choice of dozers, rippers and winches designed for efficient, high production.
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
Adjusts attachment and hydraulic power to increase both operator and machine efficiency.
Load-sensing hydraulics utilize a feedback loop from the control valve to the hydraulic pump to continually monitor the hydraulic power requirements of attachments.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.
Comfort and convenience designed into the control station for a more efficient and productive operator.
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.
Choice of Differential Steering or Finger Tip Control creates an efficient work platform.
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.
The Cat elevated sprocket tractor's modular design concept moves a generation ahead in simplified service and repair.
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.
