M109-Series Howitzer Bore Evacuator
Page J-4, Para J-6.d.(4), of TM 9-1000-202-14,
Evaluation of Cannon Tubes,
says to
use molding material when looking for pitting on your M109-series howitzer’s bore
evacuator. However, no NSN is provided for the molding material. Get it with NSN 9330-
01-564-4432. Instructions on how to apply it are on the container.
M113A3 FOV Radiator Hose Clamp
The radiator hose clamp, NSN 4730-00-278-2523, shown as Item 3 in Fig 49 of TM
9-2350-277-24P (Oct 03), is too large. Instead, use NSN 4730-00-277-6204 (CAGE 58536,
PN A-A-52506-F-06) to get the smaller clamp you need for the M113A3 FOV.
‘Course, location of the grease
Fttings is part of the problem. The
Frst grease Ftting is located on top
but inside the recessed portion of
the pintle. Its position is marked
by a small metal plate, NSN 9905-
01-341-8591. The plate is labeled
GREASE and has an arrow that
points to the Ftting.
Unfortunately,
that
plate
is
usually either missing or covered
with dirt. The pintle itself can Fll
with dirt, too. That also makes the
Ftting hard to Fnd.
The second Ftting is under the
pintle, so it’s easy to overlook
unless you know where to Fnd it.
Lube both of the Fttings weekly
with WTR, NSN 9150-00-944-
8953. Your howitzer—and your
eardrums—will thank you.

that makes it a lot

—to traverse
