Sure, you can slow the damage by occasionally wiping away any condensation
in the ammo compartment. But to really put the brakes to corrosion, you’ve got to
stop moisture.
A few bags of desiccant will do
the trick. Just open each ammo
door and put a bag or two on the
Foor between the ammo tubes and
the compartment wall. NSN 6850-
00-264-6571 gets a drum of 300
bags of desiccant.
When it’s time to pull PMCS on
the hull ammo compartment, check
the desiccant bags. If they’re moist
to the touch or if the compartment
walls are wet again, it’s time for
new desiccant.

M
echanics, a little battery acid in the wrong place will damage more than the
batteries. You have to worry about what’s
under
the batteries, too.
In the case of your M88A1 recovery vehicle, that’s the steering linkage bell crank
assembly.
The assembly is to the side and below the battery box, so any battery leakage
usually ends up on it, too. If it’s not lubed regularly, the resulting corrosion makes
the rods brittle. Eventually, they break.
So, before you lube the steering linkage bell crank assembly quarterly with GAA,
carefully wipe off any corrosion you ±nd with a rag. If the corrosion is heavy, use a
solution of water and baking soda. Wear rubber gloves and safety glasses to protect
your hands and eyes.
Next, put a light coat of GAA on the
outside of the assembly, then use your
grease gun to lube normally. The GAA
helps protect the assembly from battery
corrosion until it’s time to lube again.
