Power train electronic control system
Smooth and soft operation
D375A-5R uses a newly designed power train electronic control system.The controller registers the amount of operator control (movements of lever and operation of switches) along with machine condition signals from each sensor to accurately calculate the control of the torque converter, transmission, steering clutches and brakes for optimized machine operation. The ease of operation and productivity of the new D375A-5R is greatly improved through these new features.
Electronic Controlled Modulation Valve (ECMV) controlled transmission
Controller automatically adjusts each clutch engagement depending on travel conditions such as gear speed, RPM and shifting pattern. This provides shockless, smooth clutch engagement, improved component reliability, improved component life and operator ride comfort.
Electronic Controlled Modulation Valve (ECMV) controlled steering clutches/brakes
Sensors monitor machine operating conditions and electronically control steering clutches and brakes. Monitoring application parameters, such as size of load during dozing, incline angle of slope, and load provides smooth and easy counter-steering on downhill travel, etc.
Preset travel speed selection function
Preset travel speed selection function is standard equipment, enabling the operator to select fore and aft travel speed from three preset patterns; F1-R1, F1-R2 and F2-R2 by using the UP/DOWN switch. When the F1-R2 or F2-R2 preset pattern is selected and the travel control is moved into forward or reverse, the machine travels in the preset gear range automatically. This function reduces manual gear shifting frequency during machine operation, enabling the operator to focus on directional and hydraulic control. Preset travel speed selection is especially helpful when used in combination with the Auto-Downshift Function and reduces cycle times during repeated round trip operations.
When dozing and turning, ECMV automatically controls stroke ratio of steering clutches and brakes depending on degree of load, enabling smooth dozing and turning.
When dozing downhill, ECMV automatically controls steering clutches and brakes depending on incline of machine or degree of load, reducing counter-steering and producing smooth dozing operation.
Auto downshift function
Controller monitors engine speed travel gear and travel speed. When load is applied and machine travel speed is reduced, the controller automatically downshifts to optimum gear speed to provide high fuel efficiency. This function provides comfortable operation and high productivity without manual downshifting. (This function can be cancelled with cancel switch.)

Large blade
Capacities of 18.5 m324.2 yd3(Semi-U dozer) and 22.0 m328.8 yd3(U dozer) yield outstanding production. High-tensile­strength steel comprising the front and sides of the blade increase durability.
Dual tilt dozer (option)
The dual tilt dozer increases productivity while reducing operator effort.
Optimum blade cutting angle for all types of materials and grades can be selected on-the-go for increased load and production.
Digging, hauling, and dumping are easy and smooth with less operator fatigue.
Dozer tilt angle and tilt speed are twice that of a conventional single tilt system.
Rippers (option)
The variable giant ripper features a long sprocket center-to-ripper point distance, making ripping operation easy and effective while maintaining high penetration force.
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.
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.
The track shoe slip control system will contribute to lower fuel costs, because the engine output is automatically controlled to optimum levels for operation.

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.
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.
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.
K-Bogie undercarriage system
New K-Bogie undercarriage system combines prior advantages with new additional features.
Current features:
Effective length of track on ground is consistent. Shoe slippage is minimized, resulting in higher traction.
The idler does not oscillate under load, providing excellent machine balance. Blade and ripper penetration force remains stable for increased productivity.
New features on K-Bogie undercarriage system
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 link with wedge ring
New D375A-5R track links feature reduced press-fit force and a wedge ring. Conventional track pins are retained only with a large press-fit force. The new track link divides pin forces between the wedge ring and press-fit force. This results in easier service with 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.
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
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.
Adjustment-free disc brakes
Wet disc brakes require less maintenance.
