Keep Access Covers in Place
A
missing or loose access cover be-
tween the crew and engine compart-
ments on your AVLB can be hazard-
ous to your health.
Loose or missing covers let engine
exhaust gases into the crew compart-
ment. Carbon monoxide in exhaust gas
can kill you!
Loose or missing covers will also let
an engine fire spread into the crew
compartment before you have a chance
to get out.
So, always make sure the covers are
in place and tight. Replace any miss-
ing or damaged gaskets.
rivers, there are 10 plugs for draining the water that collects in the hull of
your MLRS. Only nine are usually remembered, though.
The dry cell drain plug is the forgotten one. It’s located between the vehicle’s
two fuel tanks. If water from rain, washing and condensation isn’t drained from
this area at least weekly, it will soak and corrode the 1W30 wiring harness.
You’re not going anywhere when that happens because the fuel pumps won’t
work.
Be very careful when you crawl under the vehicle to open the dry cell plug.
It’s located next to the fuel tank drain plugs. If you get them mixed up, you’ll
have a major fuel spill.
Just remember that the dry cell drain plug has a recessed square. The fuel cell
plugs look like conventional hex-head bolts.
rewmen, your AVLB’s engine needs plenty of
air to run smoothly.
That means the intakes to the air induction sys-
tem need to be clear of stored items—like a tarp,
camouflage net or duffel bag—so the engine gets
its needed supply of air.
The tell-tale signs of an air-starved engine are
excessive black exhaust and a big drop in power
until the vehicle eventually shuts down. Engine
and transmission damage are the end results.
It’s already happened to some crews. Don’t be
the next. Keep the area around the air inlets clear
of all items at all times. It’s the best way to ensure
the flow of air and smooth operation.
