Engine Specifications
The Hyundai heavy machinery is equipped with a Cummins QSB6.7 engine, which is a water-cooled, 4-cycle, turbocharged, charge air-cooled direct injection, electronically controlled diesel engine. It delivers a gross power of 149 kW at 2,200 rpm and a net power of 147 kW at the same rpm. The engine has a maximum torque of 95 kg·m at 1,400 rpm and consists of 6 cylinders. It complies with EPA Tier III and EU Stage III-A emission regulations and does not require derating for continuous operation up to 2,286 meters (7,500 feet).

Transmission
The machine features a 3-element, single-stage, single-phase torque converter with a full automatic power shift, countershaft type transmission. It offers four forward and three reverse speeds, with a maximum forward speed of 38.5 km/h.

Axles
The drive system is a four-wheel drive with a rigid front axle and oscillating rear axle, allowing a rear axle oscillation of +/- 13°.

Hydraulic System
The load-sensing hydraulic system includes a variable axial piston pump with a flow rate of 185 liters/min. The system pressure is 280 kgf/cm². The bucket controls are pilot-operated with a single-lever joystick control.

Brakes
The service brakes are hydraulically actuated wet disc brakes, and the parking brake is spring-applied and hydraulically released. An emergency brake automatically applies if brake oil pressure drops.

Steering System
The steering system is a load-sensing hydrostatic articulated type with a piston pump delivering 105 liters/min and a relief valve setting of 250 kg/cm².

Service Refill Capacities
The fuel tank capacity is 294 liters, with other capacities including 46 liters for the cooling system and 202 liters for the hydraulic system.
