T
he search for mud flaps and hardware for M931 and M932 tractor trucks sends
you to Fig 616A in TM 9-2320-272-24P-2. But some of the information in the fig-
ure is wrong and other information that you need is missing.
First of all, the tractor
mudflap storage kit
comes with NSN 2540-01-281-9855.
The kit contains both left-side and right-side splash guards, mudflaps, hardware and
accessories needed for first-time installation only.
Note these corrections to listed items in Fig 616A:
Here’s one easy way to get a tire off a rusted
wheel. Using the bead breaker or bead
roller/combo tool on your tire machine, push the
tire further onto the rim base to expose the rust
around the rim.
Then use a wire brush and lots of tire mount-
ing and demounting lubricant, NSN 2640-00-
256-5527, to remove the rust and lube the rim.
Once rust is removed all around the wheel, most
tires slide off the rim base with little effort.
After the tire is off, inspect the wheel for other
damage. If the wheel remains serviceable, paint
it with CARC to prevent more rust. Use Green
383. Get a quart with NSN 8010-01-229-7546 or
a gallon with NSN 8010-01-229-9561. Refer to
TB 43-0242 for precautions and procedures.
R
ust eats only one thing—
metal. Truck wheels are metal. But
not all metal in a wheel is visible
for inspection at all times.
That includes the part of a wheel
that’s covered by the tire. When it
rusts, a tire may not come off the
wheel using normal manual or
machine procedures.
This is especially true for
multi-piece wheels, where
the tire bead must be
pushed off the rim.

If rust has had
long enough to
work on the metal,
a heavy enough
layer of the stuff
can keep the tire
from being easily removed.
