[. . . ] See page 7. Photo may include optional equipment. New track link design reduces maintenance cost by making turning pins easier, with improved pin reuse. See page 9. Low-drive, long-track, seven roller undercarriage provides outstanding grading ability and stability. K-Bogie undercarriage system improves traction, component durability, and operator comfort. See page 8. Rippers (option): Variable giant Multi-shank See page 7. 3 Track shoe slip control system (option) reduces operator fatigue. See page 7. 2 D375A-5R C R AW L E R D O Z E R CRAWLER DOZER D375A-5R PALM COMMAND CONTROL SYSTEM (PCCS) Komatsu's new ergonomically designed control system "PCCS" creates an operating . [. . . ] The variable giant ripper is a parallelogram single shank ripper ideal for ripping tough material. The ripping angle is variable, and the depth is adjustable in three stages by a hydraulically controlled pin puller. The multi-shank ripper is a hydraulically controlled parallelogram ripper with three shanks. New features on K-Bogie undercarriage system Engine The Komatsu SAA6D170E-5 engine delivers 391 kW 525 HP at 1800 rpm. The fuel-efficient Komatsu engine, together with the heavy machine weight, make the D375A-5R a superior crawler dozer in both ripping and dozing production. The engine features direct fuel injection, turbocharger, and air-to-air aftercooler to maximize fuel efficiency. To minimize noise and vibration, the engine is mounted to the main frame with rubber cushions. K-Bogies oscillate with two fulcrums, and track roller vertical travel is greatly increased. Impact loading to undercarriage components is reduced and component durability is improved since track rollers are always in contact with track link. 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. 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. 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. 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.
