A
s a Soldier, you’re required to put on your cover whenever you go outside. It’s
a good idea to follow the same guidelines for the hydraulic line quick-disconnect
couplings on your AVLB.
The couplings, NSN 4730-00-257-0236, need to be capped whenever the vehicle
is separated from the bridge. Without the caps, dirt and moisture get inside the
couplings. That can damage or jam the retractable bearings inside.
If that happens, the couplings can pop loose when you try to launch the bridge.
That bridge won’t move until new couplings are installed.
A new coupling costs about twice as much as a new cap, so replace damaged or
missing caps with NSN 5420-00-816-5649. Then make sure you use ‘em!
W
hen pulling PMCS on your M119A2 howitzer, there are two very important things
to keep in mind.
The right lube to use is WTR, NSN 9150-00-944-8953. It stands up to higher
temperatures and won’t break down as fast as GAA. It’s also the lube speciFed in WP
0040 00-1 (see
Thing 1
).
Thing 2:
Select the right grease for
lubing. Most operators assume GAA is the
right lube. While GAA might be used on
most Army equipment, it is
not authorized
for use on the M119A2. GAA won’t hold up
to the higher temperatures generated by
firing the howitzer. It breaks down faster,
causing components to wear out before
their time.
Thing 1:
Always have your -10 manual
out, open and ready to use. Specifically,
turn to WP 0040 for guidance on PMCS,
including lube points. You’re sure to
miss something if you try to rely only on
memory. That leads to big trouble down
the road.
