our Paladin’s hard-working idler arm and housing don’t always get the respect—or
lube—they deserve.
It’s easy to overlook the idler arm and housing during PM. But you can’t do that if
you want to keep your Paladin riding smooth.
There are two lube points for the idler arm and housing. Miss them too often and
the arm can lock up and even shear off during operation.
The Frst lube point is
behind
the
idler
wheel
on top of the idler arm. It
gets covered with dirt and
mud, so it’s easy to miss.
Be sure to clean it off before
lubing so you don’t force in
any dirt.
The second lube point is
in a recessed area inside the
mechanical drive housing,
NSN
Because
the
lube
point
sits back out of sight, it’s
often
forgotten.
You’ll
need to remove the pipe
plug and replace it with a
grease Ftting, NSN 4730-
00-050-4208, to lube this
area. Hit both lube points
semiannually with GAA to
prevent problems.

Now?
it’s Amazing
what a little air
filter PM will do
for a fellow!
Hey,
{splut}
bub!
Keep

it
below
my
{splut}
turret line, willya?
Keeping your tank
nice and clean
helps keep the bad
stuff outta the
filters and seals.
But high-pressure
water, air or steam
can end up doing more
harm
than good.
you said it,
half-Mast!
if high-
pressure water,
air or steam
is forced
into
the air intake
system, you’re
looking at
clogged
V-packs
that can shut
your tank down
fast.
Those steps outline all
the precautions needed to
make sure I not only come
out of the wash rack clean,
but also battle-ready.
That’s
why it’s very
important to follow all
the steps in the Cleaning
and Lubrication PMCS
section of your -10 TM.
