ost crewmen run their vehicles only for the 10 minutes or so that’s required to
do PMCS. Not good. The start drains the batteries’ charge and the engine doesn’t
run long enough to put the charge back.
Several starts will run the batteries out of juice. Then precious maintenance
time is used trying to find a nonexistent fault in the charging system.
When you do your PMCS, be prepared to run the engine for 20-30 minutes to
fully recharge the batteries. Keep the engine throttled to 1,200 rpm, too. The
higher idle helps prevent another serious problem on air box-configured 6V53
engines: diesel slobber.

M577-Series, M1068-Series Command Post Carriers…
Tough
Enough?
Y
ou may be a lean, mean fightin’ machine, but you’re probably not tough enough
to manhandle the 4.2 KW generator down from the top of a command post carrier.
Try and you’ll likely be sorry. The generator is large and bulky, so it’s easy to hurt
your back or even slip and fall off the vehicle.
Even if you are tough enough, the genera-
tor’s not! Its weight strains and rips the frame
welds. The frame’s hollow tubing is too light
to be re-welded, so you have to replace the
entire frame.
The right way is the only way. Remove the
generator by using the davit and chain hoist
stowed on the top deck of the carrier. Here’s
how:
1.
Slip the davit into the mounting brackets to the side of the generator.
2.
Attach one end of the chain hoist to the davit and the other end to the lifting bar
on the generator frame.
3.
Hoist the generator above the enclosure, then swing the davit around until the
generator is clear of the carrier.
4.
Lower the generator gently to the ground.
Make sure you stand clear at all times when removing or installing the generator.
That keeps you safe in case the generator slips and falls.
D
rivers, if you’ve got banged-up fuel pods on
your M113A3 personnel carrier, chances are
you’ve been towing recently.
Whenever you make sharp turns, the trailer
tongue hits the back corner of the carrier.
A new tow pintle extension, NSN 2540-01-
458-4846, is the answer. The extension increases
the reach of the tow pintle and keeps the trailer
tongue from hitting the carrier during sharp turns.
Make a note of the NSN until it’s added to TM
9-2350-277-24P.
