MLRS Carrier…
d
raining the hull on your MLRS should be second nature, crewmen. After all, water
from rain and washing will continue to rise until you pull the drain plugs.
If you don’t drain the hull, water will eventually short out the diodes on the 1W30
cable, NSN 2590-01-104-9148, and the 1W31 cable, NSN 2590-01-104-9146.
Since those cables control the fuel pumps, your vehicle is going nowhere fast.
Once the hull’s completely drained,
be sure to close and tighten the drain
plugs, NSN 4730-00-010-3867, before
you drive the vehicle. If they’re not
closed tight, the plugs can work loose
and fall out. That will let water in
when you ford the carrier.
Clean the plugs before you install
‘em, too. Wipe off any mud or sand
that might keep the threads from
meshing properly.
Before you screw in the plugs, lightly coat the threads with calking compound,
NSN 8030-00-965-2397. That’ll hold down corrosion and keep the plugs from
sticking the next time you need to drain water.
O
ne Bradley unit stopped boresighting its TOW launchers for so long that they for-
got how to do it. When the time came to fire TOWs, they didn't know what to do or
where to find boresight information.
Other Bradley crews go to the field
with broken boresight knobs.
So don't pick and choose when it
comes to boresighting your Bradley's
weapons. Even if you're not going to
fire the M242 gun or TOW launcher,
it's still good practice to boresight
them. Then you'll know what to do
before a real battle.
The boresighting procedures for all the Bradley weapons, including the TOW, are
in Chapter 2 of both TM 9-2350-252-10-2 and TM 9-2350-284-10-2. When you
boresight the coax guns and M242 gun, boresight the TOW, too.
Don't forget to remove the TOW
borescope when you're done. Otherwise,
you damage the launcher when it's stowed.
Also remember that when you boresight
the M242, you must push in the AZ knob
before you turn it. If you force the knob to
turn without pushing it in first, the knob
can break. That means no firing.
