rewmen, you know that old saying about the squeaky wheel getting the grease? That
also goes for the idler wheel support arms on your M113-series carrier.
But you don’t wanna wait
until the support arms start
squeaking before you grease
them. That’s a sure way to
make those idler wheels idle.
It’s easy to miss the grease
fittings because they sit on
the support arms back behind
the idler wheels. And lots
of times, they’re covered
with mud.
If you don’t lube the support arms, the bearings dry out and the idler arm freezes.
When the arm won’t move, you can’t adjust track tension. That makes your vehicle
NMC.
Lube both idler arms with GAA every 150 hours, 1,500 miles or semiannually, whichever
comes first. Just remember, clean the fittings with dry cleaning solvent before you pump
in any lube. That’ll keep dirt from mixing with the grease.
Finally, put a dab of GAA on the grease fittings immediately after relubing, washing or
fording the vehicle. That’ll keep the fittings from rusting.

echanics, you’ve probably noticed that the M1-series tank’s transmission fller
neck doesn’t have a very big opening. It’s just too small to pour transmission Fuid
directly ±rom the can.
Some o± the Fuid is gonna spill,
no matter how care±ul you are. And
things don’t get any better a±ter that.
The oil cooler ±ans are gonna blow
that oil all over the oil cooler fns.
Dust is attracted to the oil residue.
The gooey mess that ±orms on the
cooling fns keeps the heat ±rom
radiating away ±rom the oil inside the
coolers. That leads to transmission
damage.
But something as simple as a
±unnel can prevent all that. A box o±
12 Fexible ±unnels comes with NSN
Never
add
oil
without using one. So get one o± these
i± your current oil ±unnel is broken or
too large ±or the transmission fller
opening.
Each ±unnel holds a quart o± oil. So
don’t pour more than a quart into the
±unnel at a time. And make sure you
wipe up any spilled oil right away.

embarrassing!
I
hate

this HapPens!
I guess in
this case, the

Your

you right up!
Look, pal, we’ve been
over this
before.
You
gotta use the right kind

gonna get all

if you’re not
prepared, my
