Can’t tell what type of roadwheels you have? The aluminum wheels have 18 small
rivets equally spaced around the rim of the roadwheel. There are no rivets on the
steel roadwheel.
You can also use a magnet.
The magnet will cling to the
steel roadwheel, but not to the
aluminum one.
Only steel roadwheels are
still available in the supply sys-
tem. If you need one, order it

M113-Series FOV…
Dear Half-Mast,
There are two different types of
roadwheels for M113-series vehicles:
steel
and
aluminum
.
My maintenance inspectors deadlined
several of our vehicles because they
had steel and aluminum roadwheels on
the same road arm. I’ve searched the
TMs, but can’t find anything that
supports what they’re saying.
What’s the straight scoop?

E
xercise only twice a year and
chances are you’ll be a flabby
mess. Fortunately that’s all it takes
to keep the M256 main gun’s recoil
mechanism ship-shape, though.
So, mechanics, don’t forget to
take a look at the tank’s DA Form
2408-4,
Weapon Record Data,
dur-
ing semiannual services.
Specifically, look to see when
the tank was last fired or the M256
recoil mechanism was exercised.
If neither has happened in the last six months,
exercise it now. The preferred methods of exercis-
ing the recoil mechanism are:
1.
Firing the main gun.
2.
Using the gun mount exerciser,
3.
Using the M3 oil pump, NSN 4933-00-712-2378.
If you don’t exercise the recoil mechanism every
six months like it says in TB 9-1000-234-13,
Exercising of Recoil Mechanisms and Equilibrators,
the gun mount seals are guaranteed to fail.
c’mon!

exercise

needs!
Dear Sergeant A.W.,
Your inspectors are right.
Mixing steel and aluminum road-
wheels on the same road arm
causes uneven wear that wears out
the roadwheels before their time.
You can mix steel and aluminum
roadwheels on the same vehicle,
just make sure you have two of the
same type on each road arm.
