so,
half-masticus,
what will make
an
end
to the
matter
?
the
bottom
line
? to get the
tension right,
they should
always
,
always
follow the info
in the dozer's
technical
manual
.
is there
not
more
their
hands
and
eyes
can
do?
certainly
! just like
a thrown horseshoe, a
missing
or
broken grouser
can be
costly
. it
will let
dirt
,
mud
and
rocks
get into
the track assembly. and that will cut
down
efficiency
as the wear
and tear piles up.
also,
they should be on
the lookout for grouser or
plate
wear
caused by
slippage
,
impact
or
friction
. another
thing-- they should make sure
the track shoe bolts are
tight
.
loose ones will
damage
shoes and links.
how will
their eyes behold a
loose bolt
?

or
track chains

he looks
for
too much
sag
here.
they look for
fractures in the
track
itself
, the
links
, the
pins
and the
bushings
.
how

know truly when
a track i

did you say.

out-of-
whack
?
"they check the idlers
and rollers for
loos
e
mounts
,
leaky seals
or
lots
of
wear
."
"and
tooth wear
on the drive
sprocket.
severe
wear will cause
the track to
jump
off
the sprocket."
"it will have a
shiny area
around
its head, or dirt
broken away
by
vibration. but
just
looking at it
won't
hack it--they have got to
use their
fingers
