M198 and M119A1 Towed Howitzers…
Dear Editor,
Units are having cable problems when they use the AN/GYK-29(V) gun
display unit (GDU) with M198 and M119A1 towed howitzers.
M198
TM
11-7440-283-12-2
doesn’t
list a cable long enough to run from
the truck’s SINCGARS radio to the
GDU when it’s mounted on the trails.
Order the cable you need with NSN
5995-01-358-1078. This 50-ft
speaker cable connects the radio in
your truck to the speaker mounted on
the M198.
Then connect the speaker to the
GDU using a W33A cable, NSN
5995-01-128-6425. That setup
lets you receive fire missions digitally
from the fire direction center as long
as your radio is in single-channel plain
text mode.
s heavy as those M88A1 engine grille plates are, you wouldn’t
think they’d move around very much. A lot of crewmen
must
believe that, since they’re leaving the plates unbolted after their
before-operation PMCS.
Despite their weight, those plates will still bounce loose and
fall into the engine compartment during operation.
If you’re lucky, only the engine is damaged. For an unlucky
few, though, a plate will land on top of the accelerator linkage
and hold it wide open.
Imagine your surprise as
you let up on the gas and the
vehicle doesn’t slow down.
Imagine your panic as you try
to control several dozen tons
of runaway vehicle. Imagine
your funeral.
Don’t
take
shortcuts.
Always bolt down the engine
grille plates before operation.
M119A1
The section chief can’t keep the section
chief assembly (SCA) with him while verifying
data on the M119A1 because the 15-ft SCA
cable is too short.
But you can fix this problem by connecting
the two SCA cables, NSN 5995-01-128-
6410, with an adapter connector, NSN
5935-00-879-8512. In most cases the
newly combined 30-ft cable is long enough
to work.

I guess that’s the long and short of it! CECOM took your
suggestions to heart, too. They plan to add the 50-ft cable
and adapter connector NSNs to Appendix D, Additional
Authorization List, of the GDU’s TM 11-7440-283-12-2.
Use adapter connector,
connect two SCA cables
Loose plate can hold

When you
come up
short…
…we’ll
provide the
length
you need!
