Komatsu-integrated design for the best value, reliability, and versatility. Hydraulics, power train, frame, and all other major components are engineered by Komatsu. You get a machine whose components are designed to work together for higher production, greater reliability, and more versatility.
The Komatsu SA6D170E engine delivers 391 kW 525 HP and 1,931 ft-lb of torque at 1800 rpm. These features, together with the heavy machine weight, make the D375A-3 a superior crawler dozer in both ripping and dozing production. The engine is designed to surpass EPA/CARB regulations, and features direct fuel injection, a turbocharger, and an aftercooler to maximize fuel efficiency.
To minimize noise and vibration, the engine is mounted to the main frame with rubber cushions. For further convenience, fuel adjustment is unnecessary up to an altitude of 3000 m 9,840 ft.
