RELIABILITY & MAINTENANCE FEATURES
Excellent Reliability & Durability
Parallel Link Undercarriage System (PLUS)
Komatsu's new PLUS provides less downtime, plus longer
wear with up to 40% lower undercarriage maintenance
costs. Rotating bushings eliminate the cost and downtime
for bushing turns, and strengthened rollers and links
increase wear life up to two times. With PLUS, individual
links can be replaced with common track tools.
Planned maintenance and daily checks are the only way
to ensure long service life from equipment. That’s why
Komatsu designed the D61EX/PX-24 with conveniently
located maintenance points to make necessary inspec-
tions and maintenance quick and easy.
Hydraulically-driven swing-up fan
The D61EX/PX-24 utilizes a swing-up fan with a gas
strut-assisted lift system to provide easy access to the
(side-by-side) radiator, oil cooler and charge air cooler.
The hydraulic fan has a cleaning mode which can be
used for periodic cooler cleaning.
One of the design goals behind the creation of the D61EX/
PX-24 was to manufacture a more durable machine. This
was achieved by reducing component complexity and using
a strong modular design for increased serviceability and
durability. Steel castings reduce the number of welds,
improving rigidity and strength.
