yeah,
but how do
you plan to
get it
off
?
rewmen, loose or missing end con-
nectors are a sure invitation to a thrown
track on your M109A6 Paladin. So,
make sure you check the track after
every operation.
Cracked and missing end connectors
are easy to spot. Loose ones, however,
are another matter. It takes sharp eyes
to detect those.
Tap each of the end connectors gen-
tly with a ball peen hammer. Watch for
any movement of the connector. If
there’s any movement at all, the end
connector is loose.
Get your mechanic to torque loose
end connectors to prevent damage to
them and the rest of the track. Remem-
ber, any missing or cracked end con-
nectors make your vehicle NMC.
Some crewmen think replacing the
wing nut with a regular nut solves the
problem. Unfortunately, there never
seems to be a wrench handy when it’s
time to check the filter. Again, the fil-
ter ends up ignored.
No, the only
real
solution is to re-
place that broken wing nut with a new
one, NSN 5310-01-064-8787. And
don’t forget to keep a washer, NSN
5310-01-353-0338, under the wing nut.
That keeps the wing nut from vibrat-
ing loose.

Uncleaned filter gets clogged quickly
Broken wing makes nut hard to remove
one or both of the wings break off.
Then the wing nut is difficult, if not
impossible, to remove by hand.
That’s too bad, because a filter that
doesn’t get cleaned or replaced regu-
larly results in a burned-up APU
generator.
rewmen, you’re supposed to clean
the generator air filter on your ammo
carrier’s auxiliary power unit (APU)
weekly. That’s hard to do if you can’t
get the weather hood off.
The weather hood is held in place
with a wing nut. It works great until
