The Cat 3126B engine is designed for easy maintenance and can be rebuilt for additional service lives. With the HEUI™ fuel system, injection pressure is independent of engine speed and provides maximum fuel delivery efficiency with low emissions. Equipped with an electronic air inlet heater, the 3126B warms the air in the air inlet manifold, for easier starting and reduces white smoke on cold starts. Machines will automatically activate the timed air inlet heater prior to engine startup.
A well-matched turbocharger and air-to-air aftercooler results in higher power while keeping rpm steady and exhaust temperatures low.
The direct injected electronic fuel system provides a controlled fuel delivery increase as the engine lugs back from rated speed. This results in increased horsepower above rated power. A combination of increased torque rise and maximum horsepower improves response, provides greater drawbar pull and faster dozing cycles. • 70% torque rise.
The D6N single-stage torque converter efficiently responds to changing load conditions by providing torque multiplication, therefore increasing drawbar pull. It provides protection to the drive train components by preventing shock loads from heavy dozing applications. The torque converter is efficiently matched to the power train components and provides the superior performance you need.
Oil cooled, hydraulically actuated, large diameter plates and clutch discs provide higher torque capacity and increased service life.
Final drives are isolated from ground and work tool induced impact loads for extended power train life.
The D6N offers both Differential Steering and Finger Tip Controls for steering. Both systems deliver the control the operators need for all applications. Soft touch buttons located on the steering controls shift the electronically controlled transmission.
The D6N has an additional transmission shifting feature for added performance and operator comfort - the Electronic Clutch Pressure Control (ECPC). This unique feature provides smoother shifting by regulating and modulating the individual clutches based on current operating conditions.
When moving straight ahead, power flows through the transmission pinion and bevel gear into the dual differential, transmitting equal, uninterrupted power to each final drive. While turning, power is shifted to the outboard track speeding it up. The inboard track slows down to accommodate a tighter turning radius. Forward ground speed remains the same throughout the turn.
State-of-the-art operator station has reduced sound levels, lower cab vibration, and increased glass area.
Differential Steering Tiller Bar control system and the optional Finger Tip Control (FTC) steering system provide simultaneous one-handed steering and transmission control.
Bi-directional hydraulic steering motor activates the dual differential, which changes the speed of individual tracks. Slowing one track and increasing the speed of the other track achieves a smooth power turn.
Proven planetary design provides fast smooth speed changes while distributing loads over multiple gears for long life.
Caterpillar elevated final drives provide isolation from ground or work tool impact loads, extending service life.
Oil cooled large diameter brake disc provide long service life.
Caterpillar 3126B HEUI engine meets worldwide engine exhaust emission regulations.
Aluminum bar plate radiator provides excellent heat transfer.
Efficient torque converter provides torque multiplication for increased drawbar pull and protects the drive train from shock loads.
The design is spacious and comfortable to promote shift-long productivity. Large glass window and door panels allow for excellent visibility to the blade, rear and sides of the machine. Door and window seal design allows for a fully pressurized low dust cab. Acoustic headliner material, and sound suppression foam panels reduce sound levels to 79 dB(A) according to the dynamic test procedure and conditions that are specified in ISO 6394:1998. Individual windshield wiper controls are located in the front section of the headliner. The cooling system is incorporated into the cab structure providing good visibility to the rear of the machine.
The instrument panel, with easy to read analog gauges and warning lamps, keeps the operator aware of any potential problems. All gauges and readouts are easily visible in direct sunlight. HVAC controls and vents are conveniently located on the dash to provide climate control for the operator. Auto-shift and Auto-kickdown controls are located within easy reach. Footpads keep the operator stable and comfortable while working on slopes.
A rocker switch control activates high or low idle with a touch of the finger. A decelerator pedal gives the operator full control of engine speed when the rocker switch is in the high idle position.
Low effort pilot operated hydraulic controls make the D6N easy to operate and provide sure, precise blade control with less operator fatigue. Ergonomically shaped blade and ripper controls provide increased operator comfort during long shifts.
The AccuGrade Ready Option (ARO) provides a factory installed on-board platform for the AccuGrade Laser System or the AccuGrade GPS installation. All of the changes required to the electrical system, hydraulic system, blade, and cab are incorporated into the ARO. Mounting brackets added on the blade allow easy installation of the masts. Mounting brackets in the cab secure the in-cab display. Plug-in points inside the cab and on the front of the machine make it easy to install electronic components.
Current earthmoving and fine grading processes are labor intensive, dependent on manpower and instruments. Maintaining consistent grade between stakes is challenging, even for experienced operators. The AccuGrade Laser and GPS Machine Control and Guidance Systems reduce labor requirements and help operators work to the design plan by accurately cutting, filling and reducing material cost.
Automatic control of the blade's lift and/or tilt, provides consistent accuracy with higher productivity by reducing blade control demands on the operator. Based on correction signals, a hydraulic control valve automatically raises or lowers the blade to maintain the correct edge elevation.
The AccuGrade Laser and the GPS systems are designed for a wide range of construction earthmoving applications requiring tight tolerances and high productivity rates. Choosing whether to use a Laser or GPS system depends on the job site requirements.
The laser system is ideal for fine grading sites with flat, single slope or dual slope surfaces such as industrial, commercial and residential building sites.
The in-cab display with easy-to-read grade indicator and backlit elevation display shows the operator all AccuGrade system information. The in-cab display arrows show the blade's position relative to grade and indicate cut or fill requirements of the work area. Push button operation allows the operator to easily switch from manual mode for rough grading to automatic mode for fine grading.
The AccuGrade Global Positioning System (GPS) is the best solution when the construction site involves contours, rather than single or dual slope planes. A GPS system compares the blade position to a three-dimensional computerized job site plan and signals the operator or hydraulic system to raise or lower the blade to achieve the design requirements.
The in-cab display provides real-time operating information to the operator. Designed for simple operation, the 140 mm (5.5 in) color LCD daylight readable display with keypad allows operators to easily interface with the system. Settings and views can be easily configured according to operator preference. The display is designed for reliable performance in extreme operating conditions including shock, dust and moisture.
All AccuGrade components are designed for dependable performance in harsh environments.
Caterpillar AccuGrade Laser and GPS systems are available at your local Caterpillar Dealer.
The pinned equalizer bar gives the roller frames the ability to oscillate up or down to better match ground contours while providing maximum traction and operator comfort.
N-Series cab supports have been stiffened. Stiffer cab supports result in lower noise and vibration in the cab, providing the operator increased comfort.
Caterpillar undercarriages are designed with full length guarding on top of the track roller frame. This prevents abrasive materials from falling down on moving parts.
Roller frames are tubular, to resist bending and twisting. • Roller frames attach to the tractor by a pivot shaft and pinned equalizer bar.
The recoil system is superior because it is protected from the elements and maintained in a sealed, oil-filled cavity for years of reliable service.
The pinned equalizer bar is saddle-mounted beneath the mainframe, allowing the roller frames and track to oscillate. The oscillation provides a steady working platform and smooth ride for the operator.
Built for tough applications where penetration and blade side loading are important. The design of the SU blade makes it excellent for aggressive dirt penetration and loading materials. The blade wings are designed for superior load retention.
Designed to conform with the 3 m (9.8 ft) width transport limit without blade removal. Allows a 0.30 m (1 ft) section on both ends of the blade to fold into transport position.
In forestry and land clearing applications where limbs and debris can damage a machine, optional sweeps are available for the N-Series. Sweeps help to shield critical components on the tractor such as hydraulic lines, exhaust stacks, cab windows and lights from damage.
Rear counterweights are available through Custom Products and can be used to help the machine's balance in severe applications such as backing up slopes or heavy angle dozing.
Less service time means more working time. Major components are designed as modules and most can be removed without disturbing or removing other components.
Diagnostic connector allows Caterpillar dealers to quickly troubleshoot the D6N or access stored data with the use of Electronic Technician (Cat ET).
This option allows the customer or dealer to obtain machine diagnostics and location from their offices. Product Link provides updates on service meter hours, machine condition and machine location, as well as integrated mapping/route planning.
The D6N features a flexible monitoring system that is easily upgraded by flashing software rather than replacing the module, reducing parts cost. As technology changes and new electronics and software become available, the monitoring system will allow the machine to be easily updated.
Ecology drains provide an environmentally safer method to drain fluids. They are included on the radiator, hydraulic tank and major power train components.
Individual radiator core modules are easily serviced without major component removal.
