You can tell when the cup’s full—
blow-by will start seeping into the en-
gine compartment. That’s too late—
the damage is already done. So, every
other day or so, remove the cup, empty
its contents into an approved container,
and clean it and the inner plastic
element.
In the field, just use a rag to clean
out the cup and element. If you’re near
a maintenance outfit, clean the cup and
element with
dry cleaning
solvent.
Whenever
possible, run
your carrier’s
engine at a
higher idle—
1,000 rpm or
so—to burn
blow-by inside the engine.
good washing is the best way to keep your MLRS clean and mean. But before
you grab that water hose, keep these things in mind:
•
Tighten all cables and cannon plugs before washing. Loose connectors will let
in water that can cause short circuits.
•
Cover the electronics unit
(EU) and electronics box
with a garbage bag before
washing. Both boxes have
a gasket to protect against
water, but you never know
when the gasket will go bad.
The bag provides an extra
line of defense.
•
Park the vehicle on an
incline with the front higher
than the rear whenever
possible. That helps water drain out quickly.
rivers, you just can’t avoid some
occasional low-rpm idling in your
M113A2 carrier. That means you also
can’t avoid the engine blow-by that
low-idling causes.
Too much crud in the “slobber cup”
creates excess pressure in the crank-
case. Your engine burns too much oil
and performance suffers.
So, clean the airbox drain and crank-
case breather collector every couple of
days rather than
weekly like it
says in TM 9-
2350-261-10.
And if you
must
idle at a
low rpm, like
when you’re in
the field, keep
an eye on the
collector cup.
