doesn’t cover everything on your
MLRS that needs regular lubing.
Some of it comes from experience.
One such spot is the idler
tensioner pulley on the rear gen-
erator belt. Moisture from conden-
sation, rain and regular washing
gives rust a foothold on the pulley.
If the pulley won’t turn, the belt
takes a real beating and will eventu-
ally snap.
Keep the rust at bay by giving the
tensioner pulley a squirt or two of oil
once a month. Not too much, though.
Any extra oil should be wiped away to
keep it off the belt.

Avoid a Hatch-tastrophe!
M
ost crewmen eventually learn the lesson, even if it means a conk on the
head: carrier hatches are too heavy to stay open on their own.
They’ll come flying shut when your vehicle hits a big enough bump. You
could end up losing your teeth, your fingers—even your life—if a hatch comes
crashing down while you’re in the way.
But it doesn’t have to happen. It only takes a few seconds to stick the safety
pin through the bracket to lock that hatch in place.
Play it safe. Lock open the hatches before moving out. If the locking pin’s
missing, have your mechanic install a new one. NSN 5315-01-266-6508 gets the
pin used for all M113-series FOV ex-
cept the M981 FISTV and M901 ITV.
For these vehicles, the driver’s hatch
pin comes with NSN 5315-01-265-
0528 and the gunner’s hatch pin comes
with the handle assembly, NSN 5340-
01-240-7321.
