980G Series II^Non-Current

Engine

Is a six cylinder, turbocharged and aftercooled 3406E Electronic Unit Injector (EUI) which is powerful enough for the most demanding work.
• Tier 2 compliant
• Four stroke engine features direct fuel injection for efficient, accurate fuel metering and excellent fuel economy.
• Oil cooled pistons and full-length, water-cooled cylinder liners maintain maximum heat tranfer for long component life.
• Turbocharging and ATAAC provide consistent, high horsepower, while ATAAC also provides for increased altitude capability.

Electronic Unit Injector (EUI)

Is a high-pressure, direct injection fuel system that is virtually adjustment-free. It electronically montiors operator and sensor inputs to optimize engine performance.

ADEM III Electronic Control Module

Along with the Caterpillar Monitoring System controls all major engine functions and regulates the timing, duration and pressure of the injected fuel. ADEM III also offers automatic altitude compensation, a cold mode start-up strategy and oil pressure and coolant warnings which result in precise engine speed control, superior cold start capability, low smoke and emissions in all operating conditions.

Cooling System

Is an electronically controlled, hydraulically driven on-demand fan system which reduces sound levels and increases fuel economy.

Separated System

The cooling system is isolated from the engine compartment and coupled with the variable rate fan, less air is required to pass through the system. This results in faster machine warm up in cold weather, increased fuel efficiency, less radiator plugging and lower sound levels.

Advanced Modular Cooling System

Utilizes an exclusive two-pass cooling system that provides significantly more cooling capacity than conventional radiator systems.

Powershift Transmission

Is heavy-duty, planetary driven and electronically controlled to provide smooth shifts that improve operator comfort and machine performance.

Integrated Braking System (IBS)

Is a Caterpillar exclusive feature that reduces axle oil temperatures, improves transmission neutralizer smoothness.

Axles

Are fixed on the front and oscillating +/- 13 degrees on the rear. The design meets the demands of Ride Control and autoshift that often result in higher speed load and carry applications.

External Axle Oil Cooler

Is available as a factory installed attachment for use in "high energy" applications, such as long distance load and carry in high ambient temperature conditions. With the availability of IBS, it is estimated that very few applications (five percent or less) and conditions will require AOC. Your Caterpillar dealer can perform an application analysis using Equipment Investment Analysis software to determine if an axle oil cooler is required.

Brakes

Braking can occur using either of the cab floor-mounted pedals. The left pedal also serves as the neutralizer and activates the IBS. This system eliminates the need for an air compressor and dryer, reducing the number of components and improving reliability.

Rims and Tires

Several tire options are available with Firestone, Goodyear and Michelin offering tread types for a wide range of conditions and applications.

Free Wheel Stator Torque Converter

The 980G Series II features a Free Wheel Stator Torque Convertor (FWSTC). A FWSTC improves machine power train efficiency in certain applications and contributes to the improved fuel efficiency of the 980GII. A torque converter provides a larger/broader output load potential than the engine can provide alone, reducing the need for very low speed gears and the number of gears required from a direct drive configuration.

Fixed Stator vs. Free Wheel Stator

The engine output shaft drives the torque converter's impeller. The impeller accelerates the torque converter fluid from low to high velocity, adding kinetic energy to the fluid. This energy is given up to a turbine causing the fluid to lose speed. The force of the oil that hits the turbine blades causes the turbine to rotate, driving the output shaft (input to transmission). The stator is a stationary reaction member between the turbine and impeller. The stator redirects the flow of oil as it leaves the turbine to increase the fluid's momentum as it returns to the impeller, increasing the unit's torque capacity. In conditions where demand placed on the torque converter is not extreme (output torque requirements equal to or less than input torque) such as when ground speed is high and resistance is low (machine slowing from high speed), turbine speed will be high relative to impeller speed. Oil passing through the turbine may then strike the back of the stator blades, eliminating the stator's ability to redirect and increase the oil's momentum. As a result, the stator actually lowers the efficiency of the system by increasing drag. Free wheel stator allows the stator to turn in the same direction as the turbine in this condition, minimizing drag on the converter and increasing efficiency.

How Free Wheel Stator Works

The free wheel assembly is a one-way clutch consisting of cam, rollers), springs and carrier. The cam is spline connected to the stator so that when the stator tries to move in the opposite direction to the turbine, the rollers are forced into the narrow end of the tapered grooves, preventing the cam and stator assembly from rotating around the carrier. Since the carrier is held stationary, the stator cannot turn and the free wheel assembly is locked. As the speed of the turbine approaches 85 percent of the impeller speed, oil passing through the turbine strikes that back of the stator blades so that the stator starts to turn in the same direction of the turbine. The cam then rotates so that rollers occupy the wide end of the tapered grooves. The cam and stator assembly are then free to rotate around the carrier (freewheel), thereby reducing drag and increasing efficiency.

Free Wheel Stator Benefits

The graph represents the efficiency of a fixed torque converter relative to an equivalent converter with a free wheel stator. When the turbine/impeller speed ratio of the two converter types is below 0.85 they perform virtually the same. Once the speed ratio exceeds 0.85, the benefit of a free wheel stator is realized through reduced drag in the torque converter. This higher efficiency results in increased fuel efficiency.
