Graphite-iron wet-sleeve cylinder liners, mono-
steel pistons, and large-diameter connecting rods
ensure long-term engine durability.
Welded bulkheads within the boom resist torsional
stress. Reinforced D-channel side frames provide
maximum cab and component protection.
Tungsten-carbide coating creates an extremely
wear-resistant surface to protect the all-important
bucket-to-arm joint.
An optional reversing fan back-blows cooler cores
to reduce debris buildup. It’s a welcome addition
that will increase uptime.
Oil-impregnated bushings enhance durability and
extend grease intervals to 500 hours for the arm-
and-boom joint and 100 hours for the bucket joint.
Booms, arms, and mainframes are so tough,
they’re warranted for three years or 10,000 hours.
1. Hydraulically driven cool-on-demand
fan runs only as needed, reducing fuel
consumption and debris fl ow through the
coolers. Highly effi cient system keeps
things cool, even in tough environments
or high altitudes.
2. Perforations in the hood and side shields
serve as a “fi rst fi lter,” helping prevent
trash entry. Anything that passes through
will also clear the eight-fi n-per-inch
cooler cores.
3. Reinforced resin thrust plates, grooved
bushings, and thermal-coated bucket
joints increase arm and boom lube inter-
vals to 500 hours.
4. You won’t fi nd a more durable swing
bearing or mainframe on comparable-
size excavators.
