Caterpillar electronic engines meet worldwide exhaust emission requirements for the EPA Tier 2 and the EU Stage II regulations. With the HEUI fuel system, injection pressure is independent of engine speed and provides maximum fuel delivery efficiency with low emissions. The Cat 3126B engines are equipped with an electronic air inlet heater. This 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 D5N single stage torque converter efficiently responds to changing load conditions by providing torque multiplication, therefore increasing drawbar power. It also provides protection to the drive train components by preventing shock loads from heavy dozing applications. This 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 D5N provides Finger Tip Control for steering. Soft touch buttons located on the steering controls shift the electronically controlled transmission.
The D5N 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.
The electronic clutch and brake steering system incorporates low effort finger tip levers allowing the operator to work more precisely in close areas, around structures, obstacles and grade stakes. Pulling the left or right finger paddle causes the machine to turn according to the amount of paddle displacement.
Machine direction is controlled by moving the machine's transmission forward/neutral/reverse direction lever. The middle position puts the machine transmission in neutral.
State-of-the-art operator's station has reduced sound levels, lower cab vibration and increased glass area.
Finger Tip Control (FTC) steering system provides simultaneous one-handed steering and transmission control.
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 clutch and brake disc provide long service life.
Caterpillar 3126B HEUI engine meets EPA Tier 2 and EU Stage II exhaust emission regulations.
Multiple Row Modular (IMRM) radiator is less subject to plugging and provides excellent heat transfer.
Efficient torque converter provides torque multiplication for increased drawbar pull and protects the drive train from shock loads.
The new cab incorporates large glass window and door panels. This allows for excellent visibility to the blade, rear and sides of the machine. New 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. The cooling system is now incorporated into the cab structure providing good visibility to the rear of the machine. Individual windshield wiper controls are located in the front section of the headliner. The new design is spacious and comfortable to promote shift-long productivity.
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 of the operator. New footpads keep the operator stable and comfortable while working on slopes.
Ergonomically shaped blade and ripper controls have low lever efforts for reduced operator fatigue. The voltage converter provides two 12-volt power supplies.
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.
Rotating Bushing Track is designed to extend system life and lower costs in highly abrasive low to moderate impact applications. RBT features bushings which rotate when in contact with the sprocket, greatly reducing bushing and sprocket wear. This design eliminates bushing turn maintenance expense and sprocket replacement costs. Rotating Bushing Track is available as optional undercarriage.
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.
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, machine location as well as integrated mapping/route planning.
The D5N features a more 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, this upgraded monitoring system will allow the machine to be easily updated.
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 D5N or access stored data with the use of Electronic Technician (Cat ET) or ECAP.
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.
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.
Your Cat Dealer offers a wide range of services that can be set up under a Customer Support Agreement (CSA) when you purchase your equipment. The dealer will help you choose a plan that can cover everything from the machine and attachment selection to replacement. This will help you get the best return on your investment.
Save money with remanufactured parts. You receive the same warranty and reliability as new products at a cost savings of 40 to 70 percent.
Whether in the dealer's fully equipped shop or in the field, you will get trained service technicians using the latest technology and tools.
Make detailed comparisons of the machines you are considering before you buy. How long do components last? What is the cost of preventive maintenance? What is the true cost of lost production? Your Cat Dealer can give you answers to these questions.
Consider the financing options available as well as day-to-day operating costs. This is also the time to look at dealer services that can be included in the cost of the machine to yield lower equipment owning and operating costs over the long run.
Improving operating techniques can boost your profits. Your Cat Dealer has training videotapes, literature and other ideas to help you increase productivity.
Repair, rebuild or replace? Your Cat Dealer can help evaluate the cost involved so you can make the right choice.
More and more equipment buyers are planning for effective maintenance before buying equipment. Choose from your dealer's wide range of maintenance services at the time of your purchase.
