Heavy-Duty Axles and Brakes
Are designed to last in all kinds of operating conditions. Two front axles disc brakes provide improved braking capability and better heat dissipation. Planetary final drives use free-floating, bronze sleeve bearings in the planet gears. • Oil disc brakes are adjustment-free and fully enclosed to lock out contaminants.

Front Axle
Is rigidly mounted to the frame to support the weight of the compactor, internal torque loads and external loads applied during compacting and dozing operations.

Rear Axle
Includes a trunnion, two trunnion supports and associated bearings, allowing it to oscillate plus or minus 12 degrees.

Four Piece Axle
Contains two axle shaft housings - the center housing and the intermediate housing. Features and benefits of this design include: • Inboard brakes on the front axle only are positioned immediately adjacent to the differential and operate on the low torque side of the final drive, requiring less braking to stop the machine.

Operator Station and Controls
Comfort and control - a top quality operator's station helps maximize productivity.

Operator Station and Controls

1 Exceptional All-Around Viewing Area
Reduces strain and fatigue, making operators more productive.

2 Caterpillar Monitoring System
With electronic analog gauges is a highly effective and reliable warning and diagnostic system. As a warning system, it constantly checks machine functions and tells the operator when there is a problem. Easy-to-read gauges display fuel level, temperatures for engine coolant, transmission and hydraulic oil, engine rpm and gear range. Hour meter, odometer and analog tachometer readings are also displayed. As a diagnostic system, it identifies conditions, shows current readings and plays back maximum or highest readings registered during recent operations. The right side panel contains a three level warning system, providing full-time monitoring of key functions. The system alerts the operator of immediate or impending problems with air inlet temperature, brake oil pressure, electrical system, low voltage, engine oil pressure, engine over-speed, fuel filter status, parking brake status, steering oil pressure and transmission filter status.

3 Quick Gear Kick Up/Down Button
Lets the operator easily downshift or upshift to a different gear. It is a convenient way to shift that saves time and effort.

4 Ignition Key Start/Stop Switch
Is positioned for easy machine starting and stopping.

5 12-Volt Power Supply and Cat Electronic Technician (ET) Diagnostics
Is provided inside the cab for powering radios, telephones or a laptop computer. This is particularly useful for powering a laptop running Cat ET to access the enhanced engine and transmission control system diagnostics.

8 Contour Seat
Is designed for comfort and support. Seat cushions reduce pressure on the lower back and thighs while allowing unrestricted arm and leg movement. • A fully adjustable air suspension seat with self-contained compressor is available as an option.

9 Built-In Storage Space
Is designed to hold cups, lunch box, insulated bottle and personal items.

10 Repositioned Vents
Throughout the cab keep fresh air flowing while improving the cab's heating, cooling, defrost and defog capability.

11 Throttle Lock
Allows and operator to set the engine speed and remove his foot from the governor (accelerator) pedal much like cruise control on an automobile. Using this feature increases productivity, fuel efficiency and improves operator comfort.

12 Decelerator Pedal
On the left acts as both an engine decelerator and a brake that overrides the engine speed selected by the throttle lock. This enables the operator to slow down when throttle lock is engaged and to return to throttle lock without pressing a button. It aids in maneuvering around shovels, haul trucks, tractors or any other obstacle.

13 Windshield Washers/Wipers
With in-the-blade washer delivery system are standard features on front and rear windows. The front wiper has intermittent speed capability.

Straight Blade
Multiple box-section construction with heat-treated moldboard and DH™-2 steel edges and end bits for long life.

Straight Blade

Blade Package
Consists of blade, push arms, trunnion mounting, dozer length skid plate, reversible cutting edges, self-sharpening end bits, hydraulic lines guard and hydraulic blade cylinders.

Outside Mounted S-Blade
With multiple box section construction including heat treated moldboard and DH-2 steel cutting edges and end bits does light production dozing, spreads fill, backfills, cleans up around trucks and shovels. The outside mounting is a stronger design because stresses are put on the frame rather than the blade so blade flexing is reduced. It also allows for higher lift and a wider blade can be used than with an inside mounted design.

Operator Controls
Lift and tilt/tip are standard options and the levers are located to the right of the operator.

Does light production work, including dozing, spreading fill, backfilling, stockpiling, charging hoppers and cleaning up around trucks and shovels.

Tire Options
Are available from Goodyear (two options) and Michelin (two options).

Is located on either side of the push arms. For each specific application, there is a correct machine weight for proper balancing of traction, flotation, mobility and response. Lower machine weight is usually required for typical second gear applications such as fill spreading, stockpiling, road maintenance, towing implements and shovel cleanup. Higher machine weight is usually required for such typical first gear applications as heavy dozing and push loading.

Air Conditioner
Uses blended air and R134a refrigerant for immediate temperature changes.

Air Suspension Seat
Provides added comfort for the operator so productivity stays high.

Fast Fill Adapter
Used during peak periods when high production is needed and little down time can be afforded for fueling. Fuel is pumped into the tank through a filling nozzle at rates up to 378.5 liters (100 gallons) per minute. As fuel enters the tank, air is forced out through an open vent. When the tank is full, the vent closes and the filling nozzle.

If maintenance is simple and areas easily accessible, it gets done.

Caterpillar Monitoring System
Provides diagnostics that allow technicians to review a machine's operation and quickly troubleshoots problems. Operating parameters, diagnostic codes and out-of-range readings are displayed through the diagnostic connector.
