Japan D375A-5R 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. [. . . ] Undercarriage life is improved due to better control of track chain alignment with track rollers. Riding comfort is improved by reducing vibration and shock when traveling over rough terrain. Track shoe slip control system (option) Eliminates the need for the operator to constantly control engine power output with the decelerator while ripping. Operator fatigue is substantially reduced. Maneuverability is improved because the operator is free to focus on the ripping application without having to monitor the track shoe slippage. Repair costs are significantly lowered and undercarriage life is prolonged with the reduction in track shoe slippage. Hydraulic driven radiator cooling fan Fan rotation is automatically controlled depending on coolant and hydraulic oil temperature, saving fuel consumption and providing great productivity with a quiet operating environment. Fulcrum of major bogie Track shoe slip control panel The track shoe slip control system will contribute to lower fuel costs, because the engine output is automatically controlled to optimum levels for operation. Automatic torque converter lockup system For greater efficiency during long pushes, the lockup mode allows the system to automatically engage the torque converter lockup clutch. Locking up the torque converter transmits all the engine power directly to the transmission, increasing ground speed thus achieving efficiencies equal to a direct drive. The result is efficient use of engine power, less fuel consumption, and faster cycle times. The cab damper mounting, combined with new K-Bogie undercarriage, softens shocks and vibrations while traveling over adverse condition that are impossible to absorb with conventional cab mounting methods. The soft spring cab damper isolates the cab from machine body, suppressing vibrations and providing a quiet, comfortable operating environment. Photo may include optional equipment. Enlarged engine room Engine room space is enlarged by increasing engine hood height, facilitating maintenance of the engine and related equipment. Solid engine hood prevents dust and rain from entering and keeps the engine clean. Gull-wing engine side covers Gull-wing engine side covers facilitate engine maintenance and filter replacement. Side covers are a thick two-piece structure with bolt-on latch to improve durability and repairability. New suspension seat D375A-5R uses a new suspension seat. Fore and aft sliding rails and suspension spring increases strength and rigidity. New seat provides excellent support and riding comfort. Fore and aft sliding amount is designed to fit all operators. Low maintenance costs Photo may include optional equipment. 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 cleaner. Cleaning interval of the filter is greatly extended, and use of a new structure filter element facilitates cleaning and replacement. Track link with wedge ring Cab damper mounting Rubber Boot Rubber Silicon Oil Spring New D375A-5R 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. guard This 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. Flat face O-Ring seals Flat face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage. 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. 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 Adjustment-free disc brakes Wet disc brakes require less maintenance. 8 9 D375A-5R C R AW L E R D O Z E R CRAWLER DOZER D375A-5R RELIABILITY FEATURES Filtration Engine Newly added main fuel filter of 2µ and water separator help protect the engine against dust and water in the fuel.
