John Deere 350D LC - Manual (Page 8)

Graphite-iron wet-sleeve cylinder liners, mono-
steel pistons, and large-diameter connecting rods
ensure long-term engine durability.
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.
Hydraulically driven fan runs only as needed,
reducing fuel consumption and debris fl ow
through the coolers.
Optional reversing fan back-blows cooler cores to
reduce debris buildup. It’s a welcome addition that
will increase uptime.
Tungsten-carbide coating creates an extremely
wear-resistant surface to protect the all-important
bucket-to-arm joint.
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.
1. With large idlers, carrier and bottom
rollers, heavier links, and 12 track guides,
the signifi cantly beefed-up undercarriage
delivers long and reliable performance.
2. Reinforced resin thrust plates, grooved
bushings, and thermal-coated bucket
joints increase arm and boom lube
intervals to 500 hours.
3. Welded bulkheads within the boom resist
torsional stress. Reinforced D-channel
side frames provide maximum cab and
component protection.
4. Highly effi cient, heavy-duty cooling
system keeps things cool, even in tough
environments or high altitudes.
5. Large box-section track frames,
thick-plate single-sheet mainframe,
and massive swing bearing deliver
rock-solid durability.
