TRACK SHOES. The most common track shoe
is the grouser shoe, as shown in figure 11-6. This shoe
is standard on crawler-mounted dozers. The extreme
service track shoe shown in figure 11-7 is equipped on
crawler-mounted dozers that operate primarily in rocky
locations, such as rock quarries and coral beaches.
Notice the grouser, or raised portion of the shoe, is
heavier than the one on the standard grouser shoe.
NOTE: The grouser absorbs most of the wear and
its condition can indicate when a track needs replace-
ment or overhaul.
The track frame serves as a framework and support
for the track assembly, rollers, front idler, recoil spring,
and adjusting mechanism.
TRACK FRAME ROLLERS. Two types of
track frame rollers are used on tracked equipment: those
located on the lower portion of the track frame, which
support the weight of the dozer, and those mounted
above the track frame, which support the track, as it
passes over the track frame assembly.
