Preventative maintenance
Preventative maintenance is the only way to ensure long service life from your equipment. That's why Komatsu designed the
D61EX/PX 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 gauge and hydraulic tank
are arranged on the right side of the machine.
Monitor with self-diagnostic function
With the starting switch turned ON, the monitor displays
check-before-starting and caution items appear on the
lower right part of the panel. If the monitor detects
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. If abnormalities occur during
operation, user code appears on display. When a critical
user code is displayed, the caution lamp blinks and a
warning buzzer sounds to prevent the development of
serious problems.
Easy/cleaning with hydraulic driven radiator
cooling fan
The radiator core and the core on the front side of the oil
cooler can be easily cleaned by running the hydraulic engine
fan in reverse. Accordingly, the cleaning intervals of those
cores can be increased.

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.

Reliable simple structure
Simple hull structure main frame design increases durability
and reduces stress concentration at critical areas. The track
frame has a large cross section and utilizes pivot shaft
mounting for greater reliability.
Maintenance-free disc brakes
Wet disc brakes require less maintenance.
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.

Clean engine
The SAA6D107E-1 engine is EPA (Environmental Protection
Agency) Tier 3 and EU Stage 3A emission regulations
certified. It developes low emission of NOx, hydrocarbon,
and particle matter, without sacrificing power or machine
productivity.
Quiet design
Rubber mounted noiseless engine and hydraulically driven
fan provide a low noise operation.

Use of recyclable parts
Recyclable parts are used to minimize the effects on the
environment.
Extended service interval
Long-life consumable parts such as filters and elements are
used to lengthen their replacement interval to lower the
maintenance cost.
