out that load, the cable comes in loose
and tangles up on the reel. Warning lights
flash, an alarm sounds and the winch
shuts down.
Then it’s decision time. And the choice
you make will determine whether the
winch works the next time you need it:
Wrong Choice:
Flip the WINCH
OVERRIDE switch to OVERRIDE
and try to force the winch to con-
tinue pulling in the cable.
Unfortunately, forcing a tangled
cable burns out the winch, NSN 3950-
01-434-3231. Your unit has to foot
the bill for a new winch—about
$95,000.
Right Choice:
Use the WINCH
OVERRIDE switch to pay the cable
back out. With the cable untangled,
apply a heavy load to the cable and
slowly wind it back in again.

echanics, retrieving the main
winch cable on your M88A2 Hercules
is tricky business.
To reel it in properly, you have to
have a heavy load attached to the
cable—such as another vehicle. With-

rewmen, the generator on your M88A1 recovery vehicle generates a lot of
heat while it provides the electrical power your vehicle needs. Cooling air is
essential if it’s to keep from overheating and shutting down.
The small air intake vent at the bottom of the back wall in the crew compart-
ment will provide that cooling air if you let it.
Tossing field packs, helmets, and
other gear against the vent blocks the
air-flow. No more air, no more power.
It’s as simple as that.
Of course, keeping the vent clear
won’t help a bit if the air intake tube
that leads to the generator is loose.
Check the clamps that hold the tube in
place. If they’re loose, tighten ’em.
While you’re at it, eyeball the tube
for cuts or cracks. They let air escape
instead of cooling the generator. If you
find any cracks or cuts, replace the tube
with NSN 9330-01-054-9780.
