Japan D375A-6 C R AW L E R D O Z E R New hexagonal designed cab includes: Komatsu-integrated design for the best value, reliability, and versatility. Hydraulics, power train, frame, and all other major components are engineered by Komatsu. [. . . ] Side covers are a thick two-piece structure with bolt-on latch to improve durability and repairability. Fresh air intake from rear of engine hood The air conditioner air intake port is now located at the rear of the engine hood where there is minimal dust. As a result, the air inside the cab is always clean. Cleaning interval of the filter is greatly extended, and use of a new structure filter element facilitates cleaning and replacement. Abnormality warning screen Maintenance List screen for replacement time display Cab damper mounting Rubber Boot Large multi-lingual LCD color monitor A large user-friendly color monitor enables safe, accurate and smooth work. Improved screen visibility is achieved by use of TFT (Thin Film Transistor) liquid crystal display that can easily be read at various angles and lighting conditions. Industry first function keys facilitate multi-function operations. Display data in 10 languages to globally support operators around the world. Rubber Low Maintenance Costs Track link with wedge ring New D375A-6 track links feature Pin press fitting force + reduced press-fit force and a wedge ring holding force wedge ring. Conventional track pins are retained only with a large press-fit force. The new track link divides pin forces between the Track guiding wedge ring and press-fit force. This guard results in easier service with Wedge ring reduced pin damage when turning pins and bushings. The result is improved undercarriage life and reduced maintenance cost through reduced wear, greater pin reusability, and reduced maintenance man-hours. increase mechanical strength, provide longer life, and protect the system from damage. Silicon Oil Flat face O-ring seals Flat face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage. Spring New suspension seat D375A-6 uses a new suspension seat. Fore and aft sliding rails and suspension spring increases strength and rigidity and reduces play of joints. New seat provides excellent support and riding comfort. Fore Enclosed hydraulic piping Hydraulic piping for the blade tilt cylinder is completely housed in the push arm protecting it from damage. Modular power train design Power train components are sealed in a modular design that allows the components to be dismounted and mounted without oil spillage, making servicing work clean, smooth, and easy. Indicators and aft sliding amount is designed to fit all operators. In addition, air suspension seat with seat isolator is optionally available, that reduces vertical and lateral vibrations more Function switches effectively. Highly reliable electric circuit The electrical circuit reliability is increased by utilizing dust, vibration and corrosion resistant "DT connectors". The reinforced electrical wiring harnesses include a circuit breaker and are covered with a heat-resistant material to Basic operation switches Maintenance-free disc brakes Wet disc brakes require less maintenance.
