Don't let the paint
shop paint parts that
need to move. If parts
like the front stays,
locking devices, equili-
brator, and gear box
are painted, they have
trouble doing what
they're supposed to.
An equilibrator or gear
box that can't function
deadlines the howitzer.
Before your howitzer
goes to the paint shop,
cover those parts that
shouldn't be painted.

When you change the
knockoff hub on the
right wheel, be sure to
replace the backing
plate, NSN 5365-01-
343-1783, and seal,
NSN 5330-01-465-
4538. They don't
come with the hub.
Otherwise the bearings
won't be tight and the
wheel can come off.
Plus the hub will wear
out fast even if the
wheel doesn't come off.
•
The PMCS for the
M119A2 doesn't pay
much attention to the
collimator, but if it
doesn't work your
accuracy suffers. When
you do weekly PMCS,
get the collimator out
and make sure its
knobs still work and the
leveling bubble moves.

(Editor's note:
You do know the "how to" of howitzer PM.
Thanks for sharing your experience.)
M119A2 Howitzer…
Dear Editor,
We have learned these lessons the hard way
-through experience.
M119A2 crews will save themselves grief if they remember these points:
•
The M119A2 has 36 grease fittings, but you'll miss some if you just go by
the LO charts on Pages 0037 00-22 and 0037 00-28 in TM 9-1015-
252-10. To hit all the lube points you must read the pages of notes that
follow the charts, which many crews don't do.
These are the fittings that are usually missed:
if they don't
all
get weekly
shots of WTR,
eventually they
will quit moving
and
break
if
you force them
to move.
…and overrun
brake lunette.
Make sure
collimator
knobs…
Don’t forget
to lube
traversing
hand
wheel…
…non-detachable spade…
…sight
mount…
…and
leveling
bubble
move
during
PMCS
Cover items like equilibrator before painting
thanks for
the how to
info, sergeant
fluharty!
you guys
at drum
sure know
your stuff!
I
TOLD
you
not
to knock
him off until
we'd replaced
the backing
plate and
the seal!
