Operator Comfort
Operator comfort is essential for productive work. The
D275AX-5E0 provides a quiet, comfortable environment
where the operator can concentrate on the work at hand.
Hexagonal pressurized cab (optional)
● The cab's new hexagonal design and large tinted glass
windows provide excellent front, side, and rear visibility.
● Air filters and a higher internal air pressure combine
to prevent dust from entering the cab.

Comfortable ride with new cab damper mounting
and K-Bogie undercarriage
D275AX-5E0's cab mount uses a new cab damper which
provides excellent shock and vibration absorption capacity
with its long stroke. Cab damper mounts combined with
new K-Bogie undercarriage, softens shocks and vibration
while traveling over adverse conditions, that are impossible
to absorb with conventional cab mounting methods. The
soft spring of cab damper isolates the cab from machine
body, suppressing vibration and providing a quiet,
comfortable operating environment.

New suspension seat
D275AX-5E0 uses a new suspension seat. Fore and aft
sliding rails and suspension spring are reinforced and play
of joints is reduced.
In addition to turning
function for ripper
operation, the seat is also
tiltable to facilitate down
hill dozing. Air suspension
seat is also available.

Preventative Maintenance
Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the
D275AX-5E0 with conveniently located maintenance points to make necessary inspections and maintenance quick and easy.
Centralized service station
To assure convenient maintenance, the transmission and
HSS oil filters, power train oil level gauges and hydraulic tank
are arranged in the right side of the machine.
All warning and monitor lamps are lit for photo shooting.
Monitor with self-diagnostic function
With the starting switch turned ON, the monitor displays P
on the display, check-before-starting and caution items
appear on the lower right part of the panel. If the monitor
finds abnormalities, corresponding warning lamp blinks and
warning buzzer sounds. The monitor displays engine rpm
and forward/reverse gear speed on the upper part of the
monitor during operation. When abnormalities occur during
operation, action code and service meter are displayed
alternately. When a critical action code is displayed, the
caution lamp blinks and a warning buzzer sounds to
prevent the development of serious problems.
Enclosed hydraulic piping
Hydraulic piping for the blade tilt cylinder is completely
housed in the push arm, ensuring damage protection from
materials.
Low Maintenance Costs
Track link with wedge ring
New D275AX-5E0 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.

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.
Oil pressure checking
ports
Pressure checking ports for
power train components are
centralized to promote quick
and simple diagnosis.
Maintenance free disc brakes
Wet disc brakes require less maintenance.
Enlarged engine room
Engine room space is enlarged by increasing engine hood
height, facilitating maintenance of the engine and related
equipment. Perforated holes on the engine hood are
discontinued, preventing dust and rain entering and to keep
engine area clean.
Gull-wing engine side covers
The opening area is further enlarged when gull-wing engine
side covers are opened, facilitating engine maintenance and
filter replacement. Side covers have been changed to a thick
one-piece structure with a bolt-on catch to improve durability.
