Advanced Modular 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.
Modular Design
The cooling elements are individual core modules that are connected to a sectioned bottom tank. There is no top tank to remove.
- With standard 9 steel fins per inch, a lower fin density reduces plugging.
- Brass tube construction within each core for improved reliability.
- Optional core configurations are available for high ambient and/or high wear applications.
Easy Serviceability
Servicing can be performed without tilting the radiator guard. Each core module can be replaced individually (without removing the entire radiator), saving considerable cost and repair time.
Protection From Leaks
To reduce the potential for coolant leaks, brass tubes are welded to a large, thick header, improving strength of the tube-to-header joint.
Attachments
In conditions with airborne abrasive materials an optional coated blower fan and sand blast grid should be used to minimize radiator damage.

Transmission

Transmission
The proven Cat planetary power shift transmission operates with three speeds forward and three speeds reverse. With this design, many gears share the load as it gets transferred to the axles. In contrast, with a countershaft transmission, just one gear carries the load.
Bevel Gear Design
Helical and spiral bevel transfer gears reduce operator and spectator sound levels by design as well as location, being placed in the rear case of the machine.
Oil Cooled Clutch Packs
The transmission features large oil-cooled clutch packs that efficiently absorb the energy of directional shifts for smooth machine performance and excellent operator comfort. Proprietary F37 clutch material extends clutch life, especially in applications where extensive maneuvering is used to maintain peak machine productivity. This material also minimizes transmission oil contamination compared to materials used in other manufacturers' transmissions.
Separate Transmission Oil Reservoir
The transmission oil sump is separate from both final drive reservoirs, controlling cross contamination in the event of a failure of either system. This allows the use of modular components to maximize uptime over the life of the tractor.
Clutch/Brake Steering
Hand levers with combined steering, control clutch disengagement and brake application for each track.
Serviceability
In terms of serviceability, the planetary transmission provides significant advantages. The modular design simplifies removal and installation. Since the bevel gears and pinions are manufactured to such a high degree of accuracy, they do not need to be lapped and mated into sets, reducing repair costs.

Torque Divider
Torque Divider Performance
An improved single-stage torque converter sends 75% of engine torque through a converter and 25% through a direct drive shaft for greater driveline efficiency and higher torque multiplication. The torque divider provides improved efficiency and a broader range of performance in second gear dozing and scraper push loading.
Operating Efficiency and Driveline Reliability
The torque divider shields the driveline from sudden torque shocks and vibration.
Freewheel Stator
Improves torque divider efficiency. During machine operation under low drawbar loads, the stator is permitted to rotate to achieve peak efficiency. The result is a reduction in heat and an increase in fuel efficiency.
Key Benefits of Torque Dividers
- High reliability.
- Proven component design.
- Low dynamic torque.
- Optimum combination of operator efficiency and driveline reliability.
- Components are designed to absorb full engine power.
- High torque multiplication to get heavy loads moving.
Additional Feedback
A minor, but important, by-product of the torque divider is its tendency to increase engine lug all the way to converter stall. This gives the operator additional feedback concerning tractor speed and drawbar pull.
Read More
Operator Station

Monitoring System
Provides the operator instant feedback on the condition of operating systems and records performance data to help diagnose problems. Gauges monitor fuel level and the temperature of the engine coolant, hydraulic oil, and power train oil. Includes alert indicators that monitor engine oil pressure, coolant flow, electrical system and transmission oil filter.
Interior Storage and Amenities
Includes intermittent windshield wipers, 12-volt power outlet, first aid kit storage, inside door releases, lunch box tie-downs, cup holder, console pads, standard 24 to 12 volt converter, speakers and antenna.
Comfortable Operation
An optional isolation-mounted cab reduces noise and vibration. The Cat Comfort Series Seat is fully adjustable and designed for comfort and support. The seat and back cushions are thicker to reduce pressure on the lower back and thighs while allowing unrestricted arm and leg movement.
Wide Panoramic View
A tapered hood and “notched” fuel tank give the operator a clear line of sight to the front and rear work areas. The low rear window lets the operator see the ripper tip. The large single-pane door windows allow clear sight to each side without leaning.
Isolation-Mounted Operators Platform
The D9R features an isolation-mounted operators platform with standard ROPS/FOPS.

Structure

Mainframe
The D9R mainframe is built to absorb high impact shock loads and twisting forces encountered during severe dozing and ripping applications.
Heavy Steel Castings
The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.
Frame Rails
Full box section, designed to keep components rigidly aligned.
Top and Bottom Rails
Top and bottom rails are made from continuous rolled sections providing superior mainframe durability.
Main Case
Elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.
Pivot Shaft and Pinned Equalizer Bar
Maintain track roller frame alignment and allow the roller frame to oscillate for smoother ride.
Equalizer Bar End Pins
Proper grease lubrication on working surfaces can significantly extend component life and help lower maintenance cost. Remote lubrication is performed from a service point conveniently located on the left hand side of the engine compartment and allows an operator or service technician to lubricate both the left hand and right hand equalizer bar pin bearings and pins from one service point.
Tag-Link
Tag-Link blade mounting brings the blade closer to the machine for excellent maneuverability, machine balance and blade penetration. This design also eliminates the need for diagonal bracing by transferring side loads to the mainframe, instead of the dozer push arms.
Read More
Undercarriage
The elevated sprocket and fully suspended undercarriage work together, increasing traction while creating a smoother ride for your operators. The elevated sprocket design transfers implement shock loads to the mainframe, so final drives, axles and steering components are isolated from harsh impacts. These benefits translate into higher production and longer component life.
- Bogie Suspension allows the track to conform to ground condition, providing up to 15% more ground contact, especially in hard, uneven terrain. Higher traction means less slippage, better balance, and a smoother ride.
- Roller frames are tubular to resist bending and twisting, with added reinforcement where operating loads are highest.
- The undercarriage idler guard provides additional wear protection from abrasive material to the moving undercarriage. Includes rubber idler protectors.
Positive Pin Retention (PPR) Sealed and Lubricated Track
Designed for high-impact and high load applications. The PPR exclusive Caterpillar design locks the link to the pin reducing the opportunity for premature loss of lubrication. Sealed design permanently coats the track pin with lubricant, minimizing metal-to-metal contact and virtually eliminating internal pin and bushing wear.
Read More
