Dear Half-Mast,
I have an M88A1 engine sling,
with two unserviceable chain
sling legs.
Fig 318 of TM 9-2350-
256-24P-1 lists only the sling.
The characteristics data in FED
LOG gives PN 11671982 for
the legs, but the part number
doesn’t cross to an NSN.
We really don’t want to pay
$1,900 for a new sling just
because of some bad chain
legs. Can you help?
SFC R.V.F.
T
he fre wire in the lower Front oF the engine compartment oF some M992A2 ammo
carriers has some extra slack, mechanics. During production, that slack was coiled up in
the corner oF the engine compartment to keep it From getting cut or damaged.
Problem is, the extra wire
was supposed to be Formed into
a dip at the Front oF the engine
compartment to provide better
fre coverage.
So iF your carrier has a serial
number oF 821 or higher, you’ll
need to secure the extra wire
the next time the powerpack
is removed. Just gather all the
slack in the middle oF the engine
compartment and clamp the fre
wire in place to the existing boss
on the carrier’s hull. Make sure
you don’t crimp the wire.
Dear Sergeant R.V.F.,
Sorry, Sergeant, but there are no
repair parts for the engine sling. The
SMR code for the sling is PEFZZ, which
means it must be replaced upon failure.
TACOM’s thinking on the matter
is safety. And it’s hard to fault their
reasoning. After all, if the legs are
broken or missing, the overall condition
of the sling itself is probably not that
good either.
Trust me—you don’t want a sling
failure to happen in the middle of lifting
that engine!
