rewmen, it’s tempting to reach for that high-pressure water hose when it’s time to
clean your tank after a mission. But the use of high-pressure water or steam is strictly
off limits for certain parts of your tank, while OK for others.
So keep a few things in mind so you don’t end up doing more harm than good.
Outside the Turret
You can use steam or water to clean the outside of your tank as long as you follow
the precautions outlined in the Cleaning and Lubrication section of your -10-1 TM’s
PMCS.
You’ll need to close all open hatches, grilles and access doors before you begin
cleaning. Also, if your tank is equipped with one, activate the turret’s inFatable seal
to protect the race rings from damage caused by water, dirt and other contaminants
being forced inside the race ring. Grease can be washed away, which opens the door
to excessive wear and corrosion. That’ll damage springs, ball bearings and the race
ring itself.
If your tank’s turret
doesn’t have the inFatable
seal, keep high-pressure
water and steam away
from the race ring area.
Be sure to grease the race
ring monthly with WTR.
That’ll
±ght
corrosion
and keep the race ring
turning smoothly.
Inside the Turret
Never
use
high-
pressure water or steam
inside
the
turret
or
driver’s station. The line
replaceable units (LRUs)
can be easily damaged
that way and LRUs are
expensive.
Water
and
electrical
components,
connectors
and
circuit
cards just don’t mix.
Use a bucket of soapy water and a nylon bristle brush to clean the inside of your
turret. Rinse with clean water from a bucket, being careful not to get water into
electrical connectors. And make sure the drain valves are open so water can drain out
of the hull.
Wipe down electrical components with a damp cloth instead of using the brush.
