2.
Try to insert the handle of a track
pin punch between the top of the No.
2 roadwheel and the bottom of the
track. If you don’t have a track pin
punch handy, place your track and
sprocket gauge, NSN 5220-01-041-
9920, flat against the side of the No.
2 roadwheel with the top touching the
bottom of the track. You should be
able to see the top of the roadwheel
through the hole in the gauge.
If the track pin punch doesn’t
move freely, or if you can’t see the
top of the roadwheel through the
track gauge, the track is too loose.
3.
Look at the No. 3 roadwheel. The
bottom of the track should touch the
top of the roadwheel. If not, the track
is too tight.
4.
Eyeball the track adjusters for
damage or leaks. The vehicle is NMC
if an adjuster is missing or has a Class
II or Class III leak.
Make sure your vehicle completes its
mission by checking track tension
and inspecting track condition as part
of your after-operation PMCS.
Here’s how…
Top of roadwheel not visible
through hole? Track is too loose
Track should touch top
of No. 3 roadwheel
boy, my
dogs are
barkin’!!
Darn
boots!
hey,
my
shoes are
in rough
shape, too.
looks like
we
both
could use a
little pm!
If you went on a
march in boots that
were too loose, too
tight or falling
apart, you wouldn’t
get far.
The same can
be said for
the track
shoes on your
M113-series
vehicle.
