The ghost seems
interested only in vehicles
that are parked without
their bridges and with the
launch mechanism in the
stowed position.
This strange phenomenon
has come to be known as
“ghost launching”.
ID Tip
Not sure if your AVLB is the
upgraded HEU? There are two
easy ways to tell. First, look
at the vehicle data plate in the
driver’s
compartment.
HEU
AVLB’s will be stamped with
an “M”. Second, look for the
yellow hydraulic breather ±lter
on top of upgraded vehicles.
M1068 Circuit Breaker
There’s now an NSN available for the circuit breaker on your M1068 command post
carrier’s power control enclosure. Use NSN 5925-01-371-0179 for Item 2 in Fig 387 of
TM 9-2350-261-24P. Also, note that the PN has changed to 12382014 and the CAGE to
19207. Make a note until the TM is updated.
M119A2 Howitzer Wrench
The 7/16 x 1/2-in open end wrench, listed as Item 50 in WP 0051 00-12 of TM 9-
1015-252-10, is no longer available. It has been replaced by NSN 5120-01-335-1203, PN
LTA1416, CAGE 55719. Make a note until the TM is updated.
1.
You can leave the bridge
on top of the HEU AVLB.
The weight will keep the
foot from moving.
2.
If the bridge is removed,
place the foot on the
ground with the tongue
parallel with the ground.
3.
If the bridge is removed
and the tongue is in the
stowed position, you can
secure the tongue to the
vehicle to keep it from
moving.
Before you make that emergency call to get rid of those pesky ghosts, check this
out: Turns out there’s no ghost at all.
The launching is due to a pressure build-up in the overhead cylinder of the bridge
launch mechanism. Motion occurs very slowly and is hard to spot with the naked
eye. But by the next morning, the foot will have moved from the stowed position.
AVLB…
units with the new hydraulic
electrical upgraded (heu)
avlb have noticed a problem:
they seem to have a ghost
loose in their motor pools.
in the motor pool,
there are three
ways to prevent
this movement…
just one of these
will eliminate the risk
of ghost launching
and damage to the
vehicle or other
equipment.
ok,
who called
about the ghost
problem?
false
alarm!
there are
no ghosts
here!
HEU AVLBs
have yellow
breather ±lter
By the next morning, the foot will move
a few inches from the stowed position
