Engine
6930, 6940, 6946, 6960
- 6930 Volvo D7EGCE3. 6940 Volvo D7EGBE3, 6946 and 6960 Volvo D7E6AE3. A 7.2 litre (439 in3) six cylinder, four stroke, direct-injection, low-emission engine which is turbocharged with charge air cooling of the air to air type. Common rail fuel system and IEGR (internal exhaust gas recirculation) are controlled by the engine electronic control unit (E-ECU) software.
- The engine has wet, replaceable cylinder liners and two valves per cylinder with replaceable valve guides and valve seat inserts. The accelerator position is transferred electrically from the accelerator pedal to the control unit (E—ECU). All models have VHP (Variable horsepower).
6970, 6976, 6990
- 6970 Volvo D9BGAE3, 6976 and 6990 Volvo D9BGBE3. A 9.4 litre (574 in3) six cylinder, four stroke, direct-injection, low- emission engine which is turbocharged with charge air cooling of the air to air type. Overhead camshaft and unit injectors and IEGR (internal exhaust gas recirculation) are controlled by the engine electronic control unit (E-ECU) software.
- The engine has wet. replaceable cylinder liners and two valves per cylinder with replaceable valve guides and valve seat inserts. The accelerator position is transferred electrically from the accelerator pedal to the control unit (E-ECU). All models have VHP (Variable horsepower).
VHP
All Volvo grader models have engines that provide three different power levels depending on the gear selected by the operator.
Electrical system
- The electrical system is a 24VDC. negative-ground system. Power is supplied by two 12VDC batteries connected in series. Battery charging is accomplished using a standard 80 amp alternator or an optional 100 amp alternator. Electrical power can be isolated using a battery disconnect switch.
- The machine has three electronic control units (ECUs). The I-ECU for the instrumentation is integrated with the display unit, warning lamps and instruments, and provides the operator with information via these.
- The V-ECU (for the machine) receives signals from sensors on the machine and these are passed on to the I-ECU and E-ECU. The V-ECU is placed in the electrical distribution box on the back wall of the cab. The E-ECU controls the engine. For D7 engines. the E-ECU is installed in the cooling module. For D9 engines, the E-ECU is installed on the engine.
Power transmission
All machine models are equipped with the standard HTE840 powershift transmission, which has 8 forward and 4 reverse speeds. All machine models can be equipped with the optional HTE1160 powershift transmission, which has 11 forward and 6 reverse speeds. Both transmissions are direct drive, fully sequential units using a countershaft design.
Rear axle / tandems
Models 6930, 6940, 6946 and 6960 are equipped with the APR7O rear axle. Models 6970, 6976 and 6990 are equipped with the APR90 rear axle. Each has an operator-controlled lock / unlock differential. Tandem wheels are chain-driven.
Brake system
Hydraulically actuated, oil disc service brakes are located at the four tandem drive wheels. The crossover dual braking circuits provide even braking on both sides of the machine. If the engine stalls or hydraulic boost pressure becomes unavailable, full braking capability is available through a reserve system. An electric motor and hydraulic pump unit supplies the power required to bring the machine to a safe stop.
Parking brake
The parking brake is a spring applied / hydraulically released, wet multiple disc brake. The brake assembly is installed inside the rear axle housing. In the event of transmission system pressure loss, an accumulator in the circuit stores system pressure and allows the parking brake to remain released for about 20 minutes.
