| Power Train | Matched Caterpillar components deliver smooth, responsive performance and reliability. | 
|
| Cat 3306 Engine | The Cat 3306 continues its tradition of powerful, efficient performance and unmatched reliability and durability. The six-cylinder engine is naturally aspirated with a high displacement-to-power ratio. This large displacement produces better lugging capability, lower internal stresses and extended component life. |
|
| Superior lugging performance | High torque output and high torque rise make the 3116 engine very responsive. The engine's lugging capability allows it to pull through sudden, short-term increases in loads, reducing the need to downshift. As a result, the operator can maintain desirable working speeds, which means the work gets done faster. |
|
| Fuel Efficiency | High fuel injection pressures ensure proper mixing of fuel and air. This high injection pressure, coupled with the precise metering and timing of the fuel injection, results in superior fuel efficiency and reduced emissions. High compression ratios ensure dependable cold-starting performance and low emissions. |
|
| Extended Engine Life | The large bore-stroke design and conservative power rating help minimize internal stresses and increase component life. The low engine speeds reduce engine wear and sound levels. |
|
| Electronic Overspeed Protection | Electronic overspeed protection helps prevent engine and transmission damage from premature downshifting and grade-induced overspeeding. |
|
| Power Shift Transmission | Caterpillar designs and builds transmissions specifically for Cat motor graders. The transmission provides on-the-go, full-power shifting as well as inching capability. | 
|
| Direct Drive | Direct drive delivers superior fuel efficiency and better "feel" of blade loads, material hardness and ground speed. |
|
| Gear Selections | Eight forward speeds and six reverse speeds give the operator a wide operating range. With four gear selections, the operator can precisely match working speeds to job conditions for maximum productivity in earthmoving applications. |
|
| Electronic Transmissions Control | Electronic transmissions control produces easy, smooth shifts, which enable the operator to maintain uniform surfaces if shifting is required. Smooth shifts also extend the life of the transmission by placing less stress on transmission clutches. A single lever controls direction, speed and the parking brake. |
|
| Inching Capability | Low pedal effort and excellent modulation provide precise control of machine movements when using the inching pedal. This is especially important in finish grading or other close-quarter work where machine control is critical. |
|
| Dual Air System | The dual air system supplies braking capacity to each side of the machine. This system ensures secondary braking capability in the event a failure occurs in a single brake line. The dual air system also has a large reserve for stalled-engine braking. |
|
| Oil Disk Brakes | Caterpillar designs and builds multi-disc brakes that are completely sealed and adjustment-free. The brakes are oil-bathed, air-actuated and spring-released. They are located at each tandem wheel to eliminate braking loads on the power train and to reduce servicing time. The large brake surface provides dependable braking capability and extended life before rebuild. | 
|
| Hydraulics | Balanced hydraulics deliver consistent, precise and responsive control. | 
|
| Power On Demand | Normally, the variable displacement pump idles at near-zero output. When it senses a load requirement, the pump supplies flow and pressure to match the demand. The result is less hydraulic system heat and lower power consumption. | 
|
| Implement Control Valves | Designed and built by Caterpillar specifically for motor graders. They provide outstanding operator "feel" and predictable system response for unmatched implement control. To help maintain exact blade settings, lock valves are built into all control valves. Line relief valves are also incorporated into selected control valves to protect the cylinders from overpressurization. |
|
| Low Operator Effort | Implement controls are designed to reduce operator fatigue. They feature short lever throws and low effort in both directions. Properly spaced control levers and short lever throws allow the operator to use multiple controls with one hand. |
|
| Balanced Flow | When the operator uses several controls at one time, flow is proportioned to ensure all implements can operate simultaneously. If hydraulic demand exceeds pump capacity, cylinder velocities will be reduced by the same ratio. |
|
| Independent Oil Supply | Large independent oil supply prevents cross-contamination and provides proper oil cooling, which means less heat build-up and extended component life. |
|
| Drawbar, Circle & Moldboard | Every component is designed for maximum productivity and durability. The blade linkage design maximizes moldboard positioning. | 
|
| Blade Positioning | The blade linkage design enhances moldboard positioning. This blade linkage is most beneficial in ditch cutting and cleaning. | 
|
| Blade Angle | A long wheel base allows the operator to obtain an aggressive moldboard angle. This aggressive angle permits material to roll more freely along the blade, which reduces power requirements. This is particularly helpful in handling very dry materials, cohesive soils, snow and ice. |
|
| Rugged Construction | The Y-frame drawbar is constructed of two solid beams. A one-piece forged circle is built to stand up to high stress loads. To resist wear, teeth are induction-hardened in the critical areas. For maximum support, the circle is secured to the drawbar by six support shoes. |
|
| Replaceable Wear Items | Tough, durable nylon composite wear inserts are located between the drawbar and circle, and between the support shoes and circle. This wear system helps keep components tight for fine grading and allows easy replacement. In addition to providing extended life, these inserts allow higher circle turning forces by reducing the friction between the circle and drawbar. Replaceable metallic wear inserts are used in the blade lift and centershift cylinder sockets, draftball surface and moldboard sli |
|
| Circle Drive Slip Clutch | The circle drive slip clutch protects the drawbar, circle and moldboard from shock when the end of the blade encounters hidden objects. It also reduces the possibility of the grader making abrupt directional changes, further protecting the machine, operator and surroundings. |
|
| Operator's Station | Caterpillar sets the standard for comfort, convenience and visibility. | 
|
| Excellent visibility | Helps improve operator confidence and productivity in all grader applications. The large front glass area and well-positioned blade linkage provide an unobstructed view of the moldboard heel and tandem tires. A wide rear window and tapered engine hood provide good visibility to the rear of the machine. | 
|
| Quiet Cab | With optional engine compartment doors and the cab doors closed, interior sound level does not exceed 77 dB(A) when tested using SAE J919 standard or 79 dB(A) when tested using ISO 6394 standard. The quiet environment keeps the operator alert and focused. |
|
| More productive work environment | Low efforts on all pedals, hydraulic controls and the transmission shifter reduce operator strain and fatigue. Pedals are angled and raised off the cab floor to make them easy to reach. Extra leg and foot room create a spacious, operator station. The operator station includes built-in storage space for personal items such as a lunch box and cooler. |
|
| Roomy Interior | Extra leg and foot room create a spacious, open cab. |
|
| Contour Series Suspension Seat | The optional contour series suspension seat features fold-up armrests and a retractable seat belt. |
|
