M981 FISTV…
Lube Keeps Head on Target
T
he targeting head on your M981 FISTV won’t be locating many targets if it does
not get lube when and where it’s needed. The hydraulic cylinder locks, elevation
cylinder bearings and pivot shaft bearings are perfect examples.
Without proper lube, the hydraulic cylinder locks suffer metal-on-metal wear.
When the detents wear out, the targeting head can’t be locked in place.
Lube the hydraulic cylinder
locks with WTR every 25 turret
hours, 250 miles or monthly,
whichever comes first.
The elevation cylinder bearings
and pivot shaft bearings control
elevation of the head. No lube
means no elevation. Plus, rust can
cause the mounting bolts to elon-
gate and snap.
Lube the elevation cylinder bearings and pivot shaft bearings with GIA every 25
turret hours, 250 miles or monthly, whichever comes first.
A
re you counting on luck to make sure the hold-open latch locks open the driver’s
hatch on your M992A2 ammo carrier? Eventually, luck will let you down.
Unless you lube the hold-open latch quar-
terly with GAA, the latch pin will rust in
place. If the pin can’t move, the hatch won’t
lock. That means the hatch could come
crashing down on your head, drivers.
Check the hold-open latch weekly to
make sure it locks. If the pin is hard to move
or won’t move at all, lube the latch until you
see grease oozing out around the pin. Then,
pull the latch knob in and out until the pin
moves smoothly.
If the pin still won’t move, report it. Your
vehicle is NMC.
Even if the pin seems to be working per-
fectly, don’t rely on it alone to hold open the
driver’s hatch.
For safety’s sake, always slide the quick-
release pin through the strike brackets on the
hold-open latch. The quick-release pin acts
as a backup in case the hold-open latch fails.
