MLRS Carrier…
Take Your Best PM Shot
Take Your Best PM Shot
Without
PM,
your MLRS
has
no
shot
at smooth
operation.
So take your
best shot
with this PM
information.
Track Deflectors
Before moving out,
take a look at the track
deflectors. They protect
the roadwheel arms
from track slap. If the
bolts are loose,
the
deflector can get caught
in the track and break
off. Tell your mechanic
about loose bolts.
Hardware
At first glance, it may seem cheaper and easier to re-use
bolts, screws and self-locking nuts on the MLRS’s suspen-
sion, steering and braking components.
It’s not.
Used hardware won’t hold. It works loose and falls out.
That results in damaged components. So toss old hardware
and replace it with the parts called out in the parts TM.
Cold Start Pump
The fittings on the cold start pump
crack from wear and vibration. Fuel
drips from the fittings to the rocker arm
covers and then onto the exhaust—a real
fire hazard.
Eyeball the fittings for cracks before
every operation. Feel for moisture and
then smell your fingers for any trace of
fuel. Immediately report a potential leak.
Radiator Plenum Seal
Check the radiator’s plenum seal at least semiannually for cracks and tears. A
bad seal lets in dirt, sand and insects that will coat the radiator fins and keep your
engine from cooling off. Make a note until this check is added to the PMCS tables.
Final Drive Sprockets
Reverse the final drive sprockets when
they wear down to the wear circle. If the
wear goes too far past the circle, the
sprocket starts hooking the track shoes.
That damages the shoes and could result
in a thrown track. When both sides of the
sprocket are worn to the circle, replace
the sprocket.
Track deflectors
loose?
Check cold start pump
for cracks or moisture
Bad seal means
dirty radiator
Reverse sprockets when
wear mark is reached
