Some Good PM
Oh, Nuts!
Stud nuts that
hold the inner
wheel assembly
together are rarely
seen. You have to
crawl under the
vehicle and look
for ‘em in the
assembly between
the rim and axle.
When one nut comes loose, the other nuts are
stressed, and can come loose, too. Then the wheel
begins to wobble, wallowing out the holes and
ruining the wheel. Enough wobble and wallow
and the wheel assembly breaks off. It’s happened!
So eyeball the nuts visually for tightness. You’ll
probably need a flashlight to see ‘em clearly.
Look for shiny spots on the stud’s washer and for
corrosion around the stud.

621B Scraper…
Scrape Up
Brake Chamber Boot
The rubber boot that protects the air brake
chamber’s spring gets worn and torn from rough
terrain, heavy use, and the elements. A torn boot
lets dust, water and dirt into the chamber, caus-
ing brake failure.
So check the
boot to see if it’s
torn away from
the chamber. If
it is, report it.
Your mechanic
can replace the
boot with NSN
2530-01-065-
9104.
After following the
PM in TM 5-3805-248-14&P-1,
go the extra mile with your
621B scraper by following
these tips
before
heading
out for your day’s work.
Check brake chamber
boot to see if it’s worn
stud nuts that
hold the inner
wheel assembly are
out of sight—
and
out of mind!
all this sand
should be
no
problem
for you…
no sir, not
since you did
your morning
round of PM!
Shiny spots around nuts?
