Dear Editor,
If the nut for the J4 connector
on the
Avenger’s Identification
Friend or Foe
(
IFF
) intercon-
nector box works loose and comes
off, the connector can actually be
pushed inside the box when you plug
in its cable. Sometimes the only fix
is to get a new interconnector box
at a cost of more than $1,000.
We stopped the nut from loosen-
ing and disappearing by lock-wiring
it to one of the screws on the front
of the box. The connector nut has
a slot to run the wire through. Your
unit armorer has lock-wire pliers.

MLRS Launcher…
Reprinted from PS 242 (1973)…
echanics, if the oil in the MLRS launcher’s elevation actuator gear housings runs
low or gets too dirty, the actuators seize up and the launcher won’t elevate.
Just
checking
the oil level annually isn’t good enough. You must
replace
it like
the -20 TM says. Otherwise that vehicle will turn into a very expensive paperweight.
Here’s the drill:
1.
Install the jury struts according to the instructions that start on Page 2-89 of TM
9-1425-646-20.
2.
Place a drip pan under the gear housing and remove the drain plug. Allow all of
the fluid to drain from the housing.
3.
Use a clean cloth to wipe off the drain plug. Then reinstall the plug a little more
than hand tight.
4.
Remove the fill and level plugs.
5.
Using a small funnel, pour gear
into the fill hole until it starts to
run out of the level hole.
6.
Reinstall the fill and level
plugs a little more than hand
tight, and wipe off any spilled
gear oil. Make sure you dispose
of the gear oil in the drip pan in
an authorized container.
