echanics, before you install the new
A-20 Global personnel heater, NSN
2540-01-396-2826, in an M992A2
ammo carrier, you’ll need to make a
few modifications.
The existing fuel pump doesn’t provide
enough pressure for the new personnel heater. Also, the personnel heater cradle
assembly doesn’t allow enough clearance to install the new heater.
Modification instructions and a list of parts you’ll need are found on Pages
3-22 through 3-25 of TB 43-0001-62-8 (Jan 99). If you need a copy, see your
local TACOM logistics assistance representative or write to Half-Mast.
rivers, there’s no need to keep the master switch on just to use your M113A3
carrier’s personnel heater or radio. Both
work just fine with the switch off.
Leaving the switch on keeps the
steering lockout solenoid energized. If
it’s on long enough, the solenoid will
burn out and deadline your vehicle.
Just make sure you remember to turn
the radio off when you turn off the
engine. If it’s still on the next time you
start the engine, you’ll end up with a
fried radio.

rivers, the canvas cover for your vehicle’s intake and exhaust grilles is made
to keep ice, snow and other debris out of the engine compartment when the
vehicle’s not in use.
The cover is
not
made to help the engine warm up faster during cold weather.
Some operators keep the grilles covered anyway. They figure the faster the
engine warms up, the sooner the mission will be accomplished.
Not true. In fact, the mission may not get accomplished at all. Leaving the
cover in place heats the engine too fast and can burn it up.
Also, fumes from the engine compartment that would normally be vented
through the exhaust grille are forced into the driver and crew compartments.
That’s a deadly proposition.
Always roll back the cover from the exhaust and intake grilles before starting
your vehicle. Secure the cover in place with the straps provided.
