Outline of electronic control system
Power Train Electronic Control System
Smooth and soft operation
D475A-5E0 utilizes 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 acculately
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 D475A-5E0 is greatly improved through
these new features.
ECMV (Electronic Controlled Modulation Valve) controlled transmission
Controller automatically adjusts each clutch engagement depending on travel
conditions such as gear speed, revolution and shifting pattern. This provides
shockless smooth clutch engagement, improved component reliability,
improved component life and operator ride comfort.
ECMV (Electronic Controlled Modulation Valve) controlled steering clutches/brakes
Sensors monitor machine operating conditions, and electronically control steering clutches and brakes depending on type of
job, such as size of load during dozing, incline angle of slope or load, providing smooth and ease of operation by reducing
counter-steering on downhill travel, etc.
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.)

Preset travel speed 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.

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 SAA12V140E-3 engine delivers 664 kW 890 HP
at 2000 rpm. These features, together with the heavy
machine weight, make the D475A-5E0 a superior crawler
dozer in both ripping and dozing production. The engine is
designed to surpass EPA Tier 2 emission regulation, and
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 drive 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:
●K-Bogies that oscillate with two fulcrums assure large
amount of track roller vertical travel. Impact load to
undercarriage components is minimized and durability of
components is improved since track rollers are always in
contact with track link.
●Track rollers follow track link movement to extend the
undercarriage life.
●Excellent riding comfort is provided due to less vibration
and shock when traveling over rough terrain.
Features on new K-Bogie undercarriage system:
●New K-Bogies with front and rear single bogies are utilized
providing increased length of track on ground to improve
machine stability.
●The oscillating idler and increased sprocket lead angle
improve riding comfort when travelling over rough terrain.
Large blade
Capacities of 27.2 m335.6 yd3(Semi-U dozer) and 34.4 m345.0 yd3(U dozer) yield
outstanding production. High-tensile-strength steel has been incorporated into the front and
sides of the blade for increased 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 up tough
material. The ripping angle is variable, and the depth is adjustable in four stages by a
hydraulically controlled pin puller.
●The multi-shank ripper is a hydraulically controlled parallelogram ripper with three shanks.
The ripping angle is variable and depth is adjustable in two stages.

Low Maintenance Costs
Track link with wedge ring
New D475A-5E0 track links
feature reduced press-fit force
and a wedge ring. Conventional
track pins are retained only with
a large 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

mounting which further improves viscous damper and
provides excellent shock and vibration absorption capacity
with its long stroke. 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.
·Operator noise: 70dB(A)
(Engine at high idle, fan speed at 70%, and air conditioner OFF)
·Dynamic noise (outside): 110dB(A) (As per ISO 6395)
Improvement of visibility in rear of blade
The shape of the blade heel and the position of the operator's
seat are changed so that the operator can check the ground in the rear of the
blade during dozing. Accordingly, the operator can work more accurately. In
addition, the position of the exhaust pipe is changed for better front visibility.
New suspension seat
D475A-5E0 uses a new air suspension seat. Fore and aft sliding rails and
suspension spring increasing strength and rigidity and reducing play of joints.
In addition to turning function for ripper operation, the seat is also tiltable to
facilitate down hill dozing.
Relocated air intake ports of air conditioner
The air conditioner fresh air inlet is located above the fender to prevent dust
from the undercarriage from entering the cab. The inside air recirculation inlet is
located behind the operator's seat, away from the dirt and dust of the floor mat,
to provide an increased cleaning/replacement interval.
