CUMMINS 6CTAA8.3 Type ......turbocharged, aftercooled, direct injection, 4-cycle diesel Number of cylinders..............................................6 Bore x stroke............114 x 135 mm (4.49 x 5.31 in) Displacement ................................8267 cc (504 in3) Governed rpm ...............STD/XLT version 2000 rpm version LGP 2000 rpm Maximum torque ....84.2 daNm (621 lb ft) at 1500 rpm Lubrication .....................full pressure by gear pump

The machine may be operated up to 2500 m (8202 ft) altitude without derating the engine.

Engine complies with TIER 2 CE 97/68, and with U.S. standards CARB & EPA.

Lubrication

Combined replaceable oil filter; the upper section includes the total flow filtering element, whereas the lower section contains the by-pass element. Minimum permissible lube pressure: -At low idle..................................0.69 bar (10 Psi) -At nominal rpm........................... 2.07 bar (30 Psi) Oil sump capacity ...............................19 L (5 USG)

Cooling system

Circulated water by centrifugal pump, integrally mounted. The coolant flows from the oil heat exchanger into the cylinder block, then passes through the cylinder head. Radiator equipped with seven blade blowing fan. Water circulation from engine to radiator regulated by thermostat. Setting of thermostat ......... 81 to 83 °C (178 to 181 °F) Max. opening ......................................95 °C (203 °F) Upper tank temperature Max. allowed .................................... 100 °C (212 °F) Max. recommended ............................70 °C (158 °F)

Fuel system

In-line BOSCH type PES.MW injection pump, with RSV governor. BOSCH drilled injectors, set at 260 + 10 bar (3771 + 145 psi). A mechanical fuel pump pulling the fuel from the reservoir. The fuel flows through a pre-filter between reservoir and fuel pump. Two replaceable cartridge filters, one with water separator and one filtering the particles in the fuel.

Air intake

Dry air cleaner with replaceable cartridges, turbocharger, equipped with WASTEGATE valve.

TRANSMISSION

Hydraulic torque converter with max. stall torque ratio 2.280 : 1. "Powershift" transmissions providing three forward and three reverse speeds, with ELECTRONIC sliding control. Moving the joy-stick to neutral the transmission is disengaged. AUTO KICK DOWN function button and AUTO SHIFT function button. Safety lock lever preventing in "lock" position the FORWARD + REVERSE operation of the joy-stick and automatically engaging the service brakes. Torque converter/transmission oil cooling by a radiator, side by side to the water radiator. Transmission oil filtered by two total flow filters; one metal mesh on suction line, the other cartridge type with by-pass valve on delivery line.

Final drives

Central bevel gear type reduction in the centre of rear transmission housing. Double reduction modular type final drives. Reduction ratio: 1 : 12.286.

STEERING DIFFERENTIAL Power Steering

The steering differential allows steering without ever locking the track, transferring power with continuity to both tracks, during the steering phase, with tight turns, as well. With the two tracks constantly under traction, it is possible to push greater loads also at maximum speed. The steering occurs by increasing the speed of one track and slowing-down the other, in an equal manner; the speed difference makes the machine steering. The steering system operates as a differential and it is composed of: a pump, an hydraulic motor and relevant controls, joy-stick actuated.

BRAKES

Oil-bath disc brakes, spring applied pressure release The single pedal actuates, simultaneously, the brakes of both tracks, both as service and emergency devices. The machine is prevented from moving with parking brakes engaged. A manual system allows the disengagement of the brakes, without hydraulic pressure, to tow the machine, in the event of a failure. Parking brake: automatically actuated, by the transmission safety lever or with engine inoperative.

EQUIPMENT HYDRAULIC SYSTEM

Hydraulic oil reservoir, equipped with level indicators, located in the back of the machine. Gear type feeding pump. Oil filtration by means of two total-flow filters: one metal mesh on pump suction line; one replaceable, with safety by-pass valve in case of clogging, on oil return line to reservoir. Three-spool, monoblock control valve. Single lever control for the first two spools of the control valve for: • raising/lowering/floating of blade; • blade tilting. Two double-acting hydraulic cylinders incorporating stroke-end and quick dropping valves in the upper sleeve, operate the blade. An optional supplementary lever is available for the third spool. A safety locking lever, retains the equipment control and gearshifting controls in neutral, to avoid accidental maneuver.

Power Steering

The hydraulic system load-sensing, controls the hydraulic power required by the steering/equipment circuits, with maximum efficiency. The flow of the steering system is prioritized, when power is required by the equipment controls, at the same time. The circuit is composed of a variable displacement piston pump and an hydraulic motor distributing adequate power to each track, during the steering phase.

UNDERCARRIAGE

Includes two welded box structure type track frames. The track frames are connected, in the front, by an oscillating cross-bar and are hinged, in the rear, on the PIVOT SHAFTS. Lubricated track chains. Two support rollers per side, permanently lubricated. Sprockets with replaceable toothed sectors. Idler wheels permanently lubricated, and hydraulic tension adjuster.
