HOW PO YOU RGURE
THIS AS Al PRIORITY
UNDER THE URGENCY
OF NEEP??

When an enemy is trying to do you in with a few well-
placed mortar or rocket rounds, it's clear that you've got to
have battle-ready equipment. '-' .

But, when there's no shooting, and everybody settles
into his peaceful job, it's not so clear that you've got to
have your equipment battle-ready. P"" I ,t

You must, though or you, your unit, your command
and your country could get caught not ready. Then the guys
who want to do you in might well do you in.
So, ready equipment is a must. No "Maybe ," "If
S. or '"Well sometimes." It's got to be ready always.
This means you bab that gear while you use it You
keep it clean, keep it cool, keep it lubed or whatever it
needs. Use the tech manual to make sure you do the
operating and maintenance jobs right
That way, no matter whether you're on the Mekong,
along the Danube, near the Korean DMZ or contented in
CONUS, you're ready, and your equipment's ready

NEW PUBLICATIONS-Manuals in the TM 9-2300-224-series
are being superseded for use with the M548 by a new series,
TM 9-2320-247. TM 9-2320-247-10 (Feb 69), TM 9-2320-
247-20 (Nov 68), TM 9-2320-247-ESC (May 69),LO 9-2320-
247-12 (Nov 68) and TM 9-2320-247-20P (May 69) in this
series have already been published.
These pubs will give you most of the dope, but here are a
few special things you ought to know....

TRANSFER GEAR CASE-The Cannibalspleas
transfer case on the M548 is dif- now uses transfer
ferent from the transfer on most 179-5608 which
other members of the M113A1 the XM730 missile
family. Instead of moving oil to
operate a ramp, its oil pump clears
oil from the transfer gear case.
If this pump conks out, oil will
pile up in the transfer. Some of it i
will be forced out the breather but
the seals will probably blow. Even
worse, the differential won't be get-
ting all the oil it needs and can
burn up. ENGINE DIPSTICK

CHECK ENGINE TWICE

IT'S TIGHT.

If you forget to screw it on, the
crankcase pressure can blow it out
and the oil can go too--leaving
you with a burned-out engine.

DIFFERENTIAL VENT-If there're HMM IT LOOKS

does, tell your mechanic. It's a sign
that you probably have a bad sump
pump on the transfer case or the
quick disconnect on the differential
return is not hooked up right.

DIFFERENTIAL OIL FILTER- Make sure it's cleaned atleastevery Q

clogged often, it means your oil's dirty, so ... change it!

AIR SEPARATOR TANK-Daily
draining of the air separator called
for by a tag attached to the tank has
been superseded by draining of the
primary fuel filter.

PRIMARY FUEL FILTER-Drain
daily before starting engine. If a
lot of water and gook comes out,
drain the secondary filter too.

AIR CLEANER-Service air cleaner element as often as necessary. (Daily in
dusty areas.) If element is frayed or bent out of shape, replace it. If you can get
100 PSI moisture-free compressed air, use it to clean the element like this:

.ou do this genil and a ithou beating up [he ends of the clement.

MAINTENANCE MUSTS

DRIVE BELTS-Generator, engine coolant
pump and fan drive belts can get thrown but it's
most likely to happen with the fan drive belts.
Check both front and rear fan drive belts and
the coolant pump belt every 50 miles or so to
make sure the tension is right.

FUEL EXPANSION TANK-If
there's a leak from your fuel expan-
sion tank get your mechanic to
work over the inside of the tank
with lacquer the way it tells in TB
750-981-2.

RIGHT SIZE DUCT?-The duct be-
tween the air cleaner and the engine
might be too short. Loosen the
clamps at each end of the duct and
pull it out. If it's 22 inches long,
(give or take 1/4-inch), replace it
with duct FSN 2940-913-1987,
which is 28 inches long (give or
take 1/4-inch).

LACQUER

LEAKS

CHANGE DATA PLATE-The data plate on the
inside of the right cab door may read that the
vehicle is an XM548E1. Scratch out or paint
over the X and the El so you are left with M548.

IF IT SAYS
"XM548E1",
CHANGE IT!

TRACK SHROUDS-In the wet season in SEA
mud and trash will ball up under your shrouds.
You're better off without 'em, so take 'em off,
and turn in to your DS, or store 'em. Do not
throw 'em away.

|TAKE OFF IN WSET\

PTO CABLE- This cahle "ill get stiff and hard
to aork unless it's lubed. Putting lube on the
cable is not cas3 because there's no grLase fitting.
So mork grease intoi it b) hand This is a little
trouble but worth it.

WOMORE>

WINDSHIELD WIPER ARMS-Some of the wind-
shield wiper arms have a bright chrome finish.
Go over 'em lightly with sandpaper and then
prime and OD paint.

WINDSHIELD WIPER BLADES-To get a good
wiping action make sure the blades are free to
move throughout their entire arc without hitting
anything.

MAKE SURE
YOU HAVE ONE
SIDE OF THE.
DOOR LOCKED
BEFORE YOU
TRY TO OPEN
THE OTHER
L SIDE.

If they hit the rubber seal that
holds the window in the wind-
shield, loosen the locknut at the
base of the arm and adjust arm as
necessary. (You may also have to
make an adjustment at the blade
adjusting screw.)

WINDSHIELD DEFROSTER-Let
the inside of the cab heat up first
before you turn on the defroster or
the sudden heat may crack a wind-
shield.

CARGO DOOR-Keep the cargo
door in place when ) ou run the e-
hice because it ties the sidewalls
together and prevents side-to-side
movement. When the vehicle is
operated without the cargo door
the rear cargo compartment sides
will break.

HEADLIGHT HAZARD-A little
trip through the brush can push
your headlights out of kilter. Get
'em lined up again before dark so
you don't put 'em on and find they
light up everything but the road.

WINCH DRAIN PLUGS-Mainte-
nance will be easier if you replace
the 6 female hex-drive winch drain
plugs with female square-drive
drain plugs FSN 4730-850-3883.

FUEL FILLER CAP-The only fuel
tank filler cap authorized for use is
the unvented type. FSN 2910-753-
9118 listed in the -20P will get you
an unvented cap. Be sure this is the
one you have.

SHIFT LEVER-If the
shift lever keeps com-
ing out of adjustment
it's a sign it's worn
out. Get a new one.
(See Pages 3-267 and
3-76 of TM 9-2320-
247-20P (May 69) for
the parts.)

NEUTRAL START SWITCH-With
this switch out of adjustment you
could start the engine with the
transmission in gear and somebody
might get hurt or the vehicle could
get damaged.
See if the starter
will work with the
transmission in re-
verse or in 1-3 range.
If it does, replace or
adjust the switch. SAFETY FIRST

.

EXHAUST STACK-The engine ex-
haust stack gets pretty hot. So when
you open the front flaps of the cargo
cover, roll them to the inside so
they won't touch the stack and get
burned. Also, keep the rest of the
front cover securely tied.

INSTRUMENT PANEL-Having
trouble with your instrument panel
lights and gages not always work-
ing? This will happen when the
panel is not firmly grounded. The
mounting bolts work loose and the
panel "floats" without having a
continuous path to ground. To
cure this make sure (he bolts are
right.

FAULTY HEATER-If the person-
nel heater is not working right,
check the control box ground wire
where it makes contact with the
control box. If it's loose, not mak-
ing good contact, your heater will
sometimes fail to work. Check the
heater troubleshooting table on
page 3-6 of TM 9-2320-247-20

STOWAGE LOCATION-The stow-
age location list in the BIIL of TM
9-2300-257-10 does not apply to
the M548. Use pages B-9 to B-16
of TM 9-2320-247-10 (Feb 69)
instead.

FUEL PUMPS-They're moisture-
resistant, but continuous soaking in
bilge water can short the wiring...
so don't let bilge water stand in
your vehicle. Turn the bilge pumps
on for a few minutes. To keep the
fuel pumps from rusting, pull the
hull drain plugs when parking out-
side in rainy weather, but make
sure they're replaced before an
amphibious operation.

NEW CLAMP-To make it easier to
remove and replace the power pack,
a quick-release V-band clamp is
standard equipment on late-model
vehicles. The new clamp, FSN
5340-886-7081, is a direct replace-
ment for the other camp.
PTO CABLE-The power-take-off
cable should be clamped either at
the ferrule or behind it. To straight-
en the loop you may have to put the
bracket in the second hole.

E C 0 N ? H OLE

FORCING-When your M548 is
combat loaded you have only a 12-
in freeboard, so the loading has to
be done exactly right. Keep the
weight balanced side-to-side for an
even keel. Careful not to overload.

FUEL TANK ACCESS COVERS-
Check the 4 fuel access covers for
loose screws. If they're backing out,
remove and clean 'em with solvent.
Draw 88 tapered lock washers FSN
5310-194-9211 (MS35336-27)
from supply. Then' reinstall the
screws with lock washers and
torque the screws to 45-50 inch
pounds. -./ / ,~ ,r I

NO SPEEDING-Your M548 is a
cargo ehiclc o ic can't be e\pecetd
to keep up with an M 113 over long
distances. Stay under 20 MPH
when fully loaded.

FINAL DRIVE-Check the torque
on your final drives often. The 10
screws on each final drive sprocket
take 100-115 lb-ft of torque. If you
let 'em get loose they can shear off.

PUSH-PULL CABLES-Operate all
of them at least once a week to
make sure they work. If they're
hard to operate, grease and adjust
them. If this doesn't work, have
them replaced.

MECHANIC'S MEMORY AID

FRONT ENGINE MOUNTS-It's
easier to get the M1548 power pack
our if )ou make up a 34f[ e\tenion
for the 15/16's soxket \ou use on
the front engine mounts.

AIR CLEANER-Need a new air
cleaner element? You can order
either of 2 optional air cleaner ele-
ments, FSN 2940-930-2065 or FSN
2940-930-2066.

DIFFERENT BARS-The torsion
bars for the M548 are different
from the bars used on the other
members of the M113/M113A1
family. Use FSN 2530-912-9511
for left torsion bars and FSN 2530-
912-9512 for right torsion bars.

TOW CABLE-The rubber strip
pads that keep your tow cable from
digging into your rear cargo door
sometimes work loose and fall off.
If you find loose ones stick 'em back
on with a dab of epoxy cement. If
they are already gone, order new
ones from pages 3-128 and 3-301 of
STM 9-2320-247-20P (May 69).

TOWING THE M548-Disconnect
both final drives before towing the
M548 or you'll run the risk of tear-
ing up your transmission.

SAFETY WARNING \
SIf you would just as soon get hit in-
the head with a steel beam, pay no at-
tention to this....
The beam you could get hit with is .
the cargo hoist beam on M548 cargo
carriers with manufacturer's serial
number of C850 or higher.
Seems the locking handle of the beam
support pin can come unlocked letting
the beam fall. ('Course there are 2 beam
supports so the beam would likely not
fall all the way but even so it could give
S TAPE IT you a nasty clout on the head.)
DOWN An MWO to take care of this is in the
works but for now make sure the beam
it j support locking handles stay locked.
/ You can do this by wrapping the
handles with a couple of turns of tape
Sor wiring them in position. Either way
is OK just so they don't unlock by
accident.
TIME SAVER
A little less slack in the track saves lots of time on your M548 cargo carrier.
Page 3-33 of TM 9-2320-247-10 (Feb 69) says "Distance must be 1/4 inch
or more with track resting on third road wheel."
Most everybody has been making it 1/4 inch on the nose-which means they
have to readjust the track every time they change the vehicle from loaded to un-
loaded or the other way around.
To save yourself sweat, tighten up on the track so the distance between the
top of the second roadwheel and the bottom of the track is 3/8 to 5/8 inches
with the track resting on the third roadwheel.
Here's how you do it and makes no difference if your carrier is loaded or un-
loaded:

Your M149, M149A1 and M625
water tank trailer and ol' man winter
don't mix without help your help.
Like when you forget to drain the out-
side pipes.
Water left in those pipes will freeze
solid.
So, in freezing weather, you drain
the pipes every time after drawing
water. You can do it fast 'n' easy:

1. Shutoff waer wit main volv 1

RB~IIII

Now the pipes are empty, and there's nothing' in there to freeze.
Although your tank trailer's got a fiberglass liner that'll keep your supply
from freezing for a long time, y'gotta be sure to keep the manhole and filler
covers battened down tight. This'll keep water heat in and freezing
cold out.
In sub-zero weather, it's a good idea to park your water trailer in a shelter
where it's warm like in a tent where there's a field range operating.
And always drain your water trailer completely if you're goin' to leave it
parked out in freezing weather for a long time.

Long before there was power steering
-or even a truck to put it in -an ol'
Roman philosopher said:
"He who has great power should use it lightly."
Now, with a li'l twist, it comes out like this:
"He who has power steering should use it right I"
Your power steering is mighty handy, especially for operation' over rough
country. What if you had to wrassle that wheel with just your own muscle power!
Even a 90-lb weakling would have no trouble ramroddin' a big truck with
power steering. But that same 90-pounder can bust up a truck's power steering
if he doesn't use it right!

power steering, though, if you try to -
turn your wheels while sitting' in a mud
hole or frozen rut.
Before you try to steer out of that bad C
spot you're stuck in, you've got to dig
out-even if you've got help from your
front-mounted winch or from another
vehicle.

So you unlimber that ol' shovel and
make space all around your front
wheels--space that's big enough and
flat enough for your wheels to roll while
you're steering.
Then you rock your truck as you turn
your wheels in the direction you want
to go.
Even when you're not stuck like
you're just parked on a good surface -
it's best to get your truck rollin' a little
before you start to turn your wheels.
Your power steering will 'preciate it.

1ST DIG OUT AROUND THE WHEELS

{( d ^@f i

NW TIME IS KILLER
Sure, you can make a hard right or
left turn with your power steering-
but for how long is the question. The
answer is:
"Never hold your steering wheel in
full steer position, right or left, for
more than 5 seconds."
Why? As you turn harder, pressure
goes up in your power steering pump.
As pressure goes up, so does tempera-
ture. So a hard turn for too long will
burn up your pump.

MWO FOR 5-TONNERS
Power steering on some 5-ton multi-
fuel engine trucks hasn't been working'
so hot, so MWO 9-2320-211-30/12
(Nov 68, corrected Sep 69) was issued
to straighten out the trouble. You'd
better check this MWO and see if your
5-ton multifuel falls in the serial num-
ber and contract number groups that
get their power steering pumps
improved.

M109
HOWITZER KIT
CONFUSION
Like you already know, the elevating
cylinder on all M109 SP howitzers serial
number 1123 and above is different
from the elevating cylinder on early
production models.
But what you might not know (and
the TM's don't tell you) is that there're
2 kinds of late model elevating cylinders
and a different seal kit is needed for
each one.
So there are 3 different elevating cyl-
inders each of which can be repaired
only with its own seal kit.
Here's the whole thing in a nutty
little nutshell for your DS:

A cool cannon cocker never lets his piece go into recoil shock if he can help it.
And tropical heat-like in SEA-really expands recoil oils in those M102 105-
mm towed howitzers.
The solution is to establish a minimum instead of normal oil reserve in your
M37 recoil mechanism.

Watch the replacement oil for contaminants to be sure only oil enters the recoil
mechanism. And make certain all air is purged from the filling hole by twisting
down on the oil gun handle as far as possible before removing the gun.
Just as important... wait for the lowest possible temperature to reduce your
reserve. This will leave the most space for heat expansion of the recoil oil during
firing of the weapon.

YOUR M2'S SPARE BOLT e4
WITH THE "IN" CROWD? IL0 AJi J

^s.)t<(v41d 4 Th

Heck, you'd never tool off to Nowheresville with a spare tire that doesn't fit
your car.
So why take the much bigger risk of toting along a spare bolt that won't
work in your flexible or cupola-mounted M2 50-cal machine gun? Matter of fact,
why keep any M2 part that you can't depend on?
Here's the pitch: Certain parts in your bolt group must get along with certain
other parts in the barrel extension and buffer groups-compatibility of internal

parts is the name and aim of this game. -
With all the old M2 parts still kicking around you could get fouled up ...
Time was you had a choice of 4 combinations of old and/or new parts in these
3 groups. But now the choice boils down to the buffer parts only--those certain
parts in the bolt group and barrel extension must all be new.
This chart'll show you. The parts with FSN's are new-the ones with part
numbers are old and can't be requisitioned any more.

BACK OVER THE PARTS.

A WORD ON OLD PARTS AND SPARES

Be sure you check that old body and
buffer carefully. If either one is badly
worn or chipped or bent or otherwise
damaged, replace 'em with new ones.
These oldies, y'know, aren't made any
more.
And make a habit of checking your
spare bolt regularly, just like you'd
double-check the air pressure and con-
dition of your spare tire. Keep that bolt
protected in the spare parts box. Take it

out once a month anyway for cleaning
and lubing and inspecting.
'Cause in the showdown your M2's
never any better than its spare bolt.

SLANT TOWARD THE SLOT

To have as little breechblock driver
cracking as possible, you need to adjust
the counterbalance assembly for smooth
and even operation of the breech so it
opens and closes without slamming or
so you won't have to use a lot of muscle.
If your counterbalance needs adjust-
ment your friendly support mechanic
can easy do it by following para 65
on page 131 of TM 9-1025-200-35
(Apr 65).
This applies to all 155-MM towed BREECHBLOCK
howitzers including the M114, the DRIVER
M114A1 and the M123A1.

PULLING HUEY (UH-1) WINTER

AIR
MOBILITY
A, -

When the barometer drops and the snow begins to fly up -j /
north, pulling maintenance is no bed of roses.
That goes double when you're out in the boonies and you
can't get your bird under cover. Keeping 'er "snug as a bug
in a rug" is your number-one goal.

USE BIRD COVERS
This is the time to dig out the all- P
weather covers and put them on your WINTER COVERS
baby.
The covers are made of soft-back
cotton twill with an aluminum colored
waterproof outer surface. They'll keep
the snow off of the rotor blades, trans-
mission and 90-degree gear box-pre- 7/
vent water from getting into the bird i
where it can freeze up the works.

Cover protection will get your bird back in the blue much faster, with less
elbow grease, than going thru a deicing chore on unprotected surfaces.
Use covers when the bird is outside for a half-day or longer in freezing tem-
peratures, when you expect rain or snow.
One point, tho. Be sure the surfaces to be covered are dry so the covers won't
freeze to the bird. Secure 'em with the tie cords and eyelet tabs attached to the
covers.

SAMPLE THE FUEL
JP-4 fuel in your bird will keep 'er purring no matter how low the temperature
goes. Not so with JP-5, which will give you long starts and erratic heater opera-
tion (if you have a combustion type heater) at temperatures lower than +10
degrees F.
Use JP-4 and be sure it's clean and DRY. Water in the tanks can cause the
fuel boost pumps to freeze ... you won't even get off the ground.

-TANK SUMPS.

Drain the water out of the fuel system before running the pumps again.
You could even have trouble with the fuel filter which is a two-stage job with
a bypass valve.
If the element becomes dogged with ice particles the bypass valve will divert
the fuel into the second stage of the filter. At this point the fuel filter caution light
will come on which means that the element has to be cleaned before the next
flight.

Your best bet to keep water out of the
fuel is to make with the sampling jar
regularly.
Water will settle to the bottom of the
fuel tanks so drain off JP-4 until you
get no more water.

so that you can haul ex- .
ternal loads.

When the landing light is lowered for a touchdown in white stuff, eye the
light cavity before it's retracted. A packed cavity will prevent the light from
going all the way up and damage the motor.
Sweep loose snow out of the cabin before each flight. Otherwise, it will turn
to water when the bird heater is turned on and run into compartments under
the floor. The water will freeze and give you a gradual weight increase ..
maybe even restrict control movements! Be sure you eye the drain tubes in the
fuselage and tail boom. Tubes jammed with ice and snow won't hack it.
If your baby gets caught out in the cold get rid of ice and AT LEAST
snow, especially on the main and tail rotor blades. Do it up THE BLADES
brown. If ice and snow removed from the rotor head and RCLE
blades lands on the fuselage or tail boom clean it off before
it freezes.
You'll find all the info you need to do the job in TM 55-410 (7 Mar 66) ...
Chap 2, Maintenance Under Cold Weather Conditions.
Pulling maintenance during the winter is going to take extra time and muscle.

WATER IS TROUBLE

T TOLD YOU
WE HAD A WEAK -
CABLE I...

wVA5 ONLY
ONE STRAND!

The weak link in a chain, or an aircraft control cable, can upset the applecart.
Oh, the cable won't fail sudden-like because it's made up of 7 strands with
either 7 or 19 wires in each strand. It's woven together for added strength.
But, one wire will let go-then
another. You'll have time to spot broken
wires, and save the day, if you eye the
control cables as called for in the bird
PMI and PMP checksheets.
EYE THE (ABLE

When you eye the cables focus on
those places where the cable makes con-
tact with pulleys and fairleads. That's
where you'll get cable wear and broken
wires.

Even with 20-20 eyesight you can't spot broken wires right-off. And running
your hand along the cable will give y~ou a mean cut when you hit a broken wire.
So, latch onto a piece of cloth. Cheesecloth works real well.

The checksheets usually have the lowdown on how many broken wires are
allowed m each strand before the cable has to be changed.

iIAI]N C:AB TYP Ain.:ll IL OESIlPE STAl

If you have any doubts that a cable is good after your broken-wire count,
change the cable. A corroded cable, for example, should get the heave-ho.
Scrap badly worn cables even tho the number of broken wires is within limits.
Here're the wear limits.
Any 7 x 7 cable with 3 wires or less per inch worn not more than half way
thru the wire diameter, or any 7 x 19 cable having 6 wires or less per inch worn
not more than half way thru the wire diameter is OK. No broken wires are
allowed in the wear spots.
One less worn wire is allowed for each broken wire in the same inch. It's OK
to have more than one wear spot along the cable. But no adjacent wear spot is
allowed around the circumference of the cable.
When you come across a kinked, twisted or bird-caged condition that won't
straighten out under normal cable tension, change the cable.

... BY THE NUMBERS!

Dear Windy,
In addition to the aircraft periodic inspection, the PMP checklist calls for other checks
to be made every 2nd thru 12th time around.
How do you figure which ones are due when the aircraft is past the 12th PE?
SP4 J. O. F.
Dear Specialist J. O. F.,
Focus in on block 9 of the DA Form 2408-13 for your bird to see what number
PE is coming up next.
Then, just divide all the frequency numbers on the checklist into the PE num-
ber. Only those extra checks that divide evenly into the PE number are to be done.
Say, for example, your bird had been around a spell and the PE number is 33. If
numbers 2 thru 12 are in the frequency columns of the checklist the only num-
bers that divide evenly into 33 are "3" and "11".
So, only those checks called for every 3rd and 11th PE are pulled, in addition
to the regular PE items. /)/

NEW BIRD PUB
If there's a brand-spanking-new Kiowa (OH-58A) in your future run your
peepers over a copy of TM 55-1520-228-20 (Jul 69). It has all the organiza-
tional maintenance poop for the Army's newest light observation helicopter.

USE NEW OIL
The word in message AMSAV-R-EU-6-1339 (20 Jun 69) is that you can now
use MIL-L-23699 oil in the Huey and HueyCobra main transmission, gear boxes
and main rotor hub when the temp's above -25 degrees F (-32 degrees C). Con-
tinue to use MIL-L-7808 oil if you're operating in temps below -25 degrees F.

7NAPE--NOPE, USE CHIN PAD

STRAP
Read and heed that Ch 2 (Sep 68) to P
TM 10-8415-202-13 (Sep 66), which
covers your APH-5, APH-5A, and
AFH-1 protective flying helmets.
You use nape pad, FSN 8415-926-
2300, on the nape strap, and you use
chin pad, FSN 8415-753-5993, on the OflN
chin straps on all helmets. If you're ST
using the nape pad as a chin pad, better
order the chin pads pronto.

NO OMFER ... PITCH IT

Anyone maintaining Sioux (OH-13E,
G, H, S and TH-13T) helicopters with- HORN
out chamfered pitch change horns,
better go talk with support.
Some P/N 47-120-126-1 horns got
by without having the chamfer modifi-
cation applied by TM 1-1H-13-533
(Oct 57). Even though this publication LOOK
is rescinded, the chamfer is still required FOR
to prevent possible interference between THIS
the pitch change link and horn. AMF
Use Figure 8-14 in your TM 55-
1520-204-20 (Jun 66) for a guide. And
if you find a -1 without the chamfer,
ask support to replace it with a -3 or -5

NUTS ON THE FUEL CONTROL

Dear Windy,
A discussion has come up on the Huey
T53-L-13 and T53-L-15 engines about the
safety on the actuating rod on the inlet
guide vane actuator to fuel control.
Do the rod bolts require a castellated
nut and cotter pin or a self-locking nut?
SFC C. N.T.
S0 Fort Eustis, Va.
C S THAT NUT
S \ WON'T HACK
C IT!

Dear Sergeant C.N.T.,
Would you believe one model gets a
nut and the other one doesn't? It's true!
The T53-L-15 bolt is put through an
unthreaded lever arm and is held by a
castellated nut (P/N AN150432) and
cotter pin.
The T53-L-13 rod is held at the fuel
control end with a bolt put through a
threaded lever arm and secured with a
cotter pin-no nut needed.
'Course, the rods for both engines on
the actuator end need a washer, self-
locking nut (P/N MS21042-3) and a
cotter pin to hold the bolt.

OE or PE for M113?

If you've got any of the M113 (gasoline engine) family of vehicles, LO 9-

2300-224-12 with changes 1 and 4 could get you a little confused about what

kind of oil should be in the transmission.

You should have the original PE oil until the first 2000-mile or semiannual

oil change-after which you use one of the OE group of oils, (OE 10, OE 30 or

OES) according to the temperature. If you need to add oil before your first oil

change use OE, not PE. Change 5 to the LO should make this clear.

N 1 DRY CEL BATTERY TESTER
COUNATION NOW YOU KNOW...

WHEN YOU GOTTA GO

DOES IT...OR
DOESN'T IT A

1LET'S GO!

So here you are. Ten minutes till the patrol leaves, one dry cell battery to
your name and you're not quite sure whether it's got the juice to get the
message back till you get back.
Routinely, you'd probably toss the battery and scrounge a fresh one ..
somewhere.
Chances are good you'd be tossing a serviceable battery. If everybody did
that, it'd cost Uncle enough to pay for a division's R & R.
So wot to do?
So latch on to an AN/PSM-13 battery test set, a fiendishly clever and simple
dry battery tester that takes about a minute, maximum, to tell you how good
your battery is.

handy canvas carrying bag, the CW-843( )/PSM-13, FSN 6625-936-5490,
which lets you carry the test set and any 2 adapters in separate compartments.
SB 11-623 (30 Jun 69) has the requisitioning details, including emergency
requirements.

If you've got magnesium batteries, such as the BA-4386 for the PRC-25,
use the BA-386 adapter. A green or yellow reading on the magnesium bat-
tery means you've got double the life of a similar reading for the BA-386.
Same goes for the BA-4505 of the PRR-9. Use the BA-505 adapter ... and
ditto.
The adapter connectors give you readings for specific batteries and for
each section of compartmented batteries. Like, if you've got a 3-section battery,
its specific adapter, plus the selector switch on the tester, allows you to check
each section.
Naturally, you rate the battery on its worst section. If one section rates
"BAD," then all are rated bad.

The SELECTOR SWITCH has

Maintenance is simple. The opera-
tor keeps the exterior and the meter
glass dean (and unbroken); checks the
switch for binding or looseness, and "- j'"y
assures that the meter pointer is not
stuck or bent. There's a pin straight-
ener (FSN 5120-935-0749) that comes
with the set in case you should bend
the adapter pins.
The unit repairman replaces the KNOB
switch (Knob, FSN 5355-616-9659) FSN 5355.616-9659
and the adapters when necessary.
So there it is. A quick, simple test

GUIDEPIN GUIDE

' Broken guides and bent pins on PCM panels of multiplexers like the TD-
202, -204 and -352 can be avoided with a "do" and a "don't."
Do line up the panel guidepins and push 'em in gently .. by hand.
Don't bang 'em into place from the rear or try to force them.

THE SITUATION

There's a new FSN for the blower
vent-hole cover to be installed on your
early model MT-1029 mount for the
RT-524 and RT-246 receiver-trans-
mitters.
You can request the detachable cover
under FSN 5820-918-7783.
Y'see, if you're making' messages
with one of the early models of the
M-1029/VRC mount, you'll need a
blower vent-cover to cut down chances
of damage to the blower on the RT-524
or RT-246.
That goes even more when the AN/
VRC-12 radio series is installed in
open-type vehicles.
Your authority for ordering the
cover is still SB 11-586 (Aug 64), which
gives installation procedures.

FOLO WITH 'BOLO'

Next time you turn in your AN/URM-98 wattmeter for repair, be sure
to include the MX-2144( )/U radio frequency bolometer. The bolometer is
required in order to calibrate the URM-98. As a basic issue item, it goes wherever
the URM-98 goes.

Hey, there, operator friend, the fact that the CV-1548/G telephone signal
converter, multiplexers TD-202/U, -203/U, -204/U,-352/U, -353/U and a few
other multi-channel communications systems items have screwdrivers handily
attached doesn't mean you should merrily go about turning every channel and
tuning screw in sight.
Let those panel screws alone.
The screwdriver's for maintenance types, who use it with handy test equip-
ment like oscilloscopes and such.
Messing with 'em can put your equipment down.
'Nother thing. That test button on the 18A3A and 18A3B panels of your
CV-1548 takes the light touch to do its job.
Heavy fingering can push the button clear into its shell.

r Once upon
a crazy time, like
there sacked out in
this lovin' supply room
a groovy chick, name of
Connie and her teenie
boppin' DA Form 2765.
All day long she
would rap with the
swingers from supply
and maintenance- telling
about how it really is and
how to do their thing-
So, one day, when it
came time to send little
DA Form 2765 back to support
to get supplies, she gathered
all the parts poppers 'round
her and ... '

0W WHEN YOU
ISEND TIS5 FORM OUT \j
ON 175 JOURNEY TO
SUPPORT, AAAKE SURE
IT'S FILLED OUT RIGHT!
FOR A CARELESSLY MADE-
OUT FORM WILL DELAY
RECEIPT OF YOUR
REPAIR PARTS... AND
FOUL UP THE WORKS.

TROUBLE-SHOOTING DA FORM 2765,
REQUEST FOR ISSUE OR TURN-IN...

HANDLE THE FORM RIGHT

What can you do to help speed up your supply of
repair parts?
Could be you can do a heck of a lot.
For a starter-how's your SOP on DA Form 2765?
Do you fill the form out right? Do you read it right when
it comes back to you?
The form's like money in the bank for your shop, you
know. It's your buyer at supply support. And, how well
it does on its shopping trips, always depends on how
well it's made out.
A form with incomplete, incorrect or scribbled info
(in most any block or column), will delay a request, foul
up the support types, and most likely will bounce back
empty handed. So, the first rule is: Accuracy across-the- jj
board for all your repair parts requests.
For easy step-by-step guidance on making out a DA
Form 2765, check Figs 4-1 and 4-2, and para 4-1, in HEH
Change 1 to AR 735-35 (Oct 65). And, right now here
are some pointers to help you check your SOP on request- pTHAT
ing repair parts. FORM
WILL
NEVER
IS Be Right Always double-check each request before MAKE IT--
VHAT you shoot it in. Write clearly, use the right info in the right THEY'LL
STO IT spaces, and give exact item identification (FSN, nomenco- SKEWER
GETS ture, plus all other info you're responsible for). SURE.
TD You don't have a pre-printed 2765? Then be real sure
BACK! all your entries are accurate. HFW

Pre-prints- Handle pre-printed 2765's
carefully Keep 'em clean and fresh. And, even
if you keep 'em filed with the DA Form 3318
covering the item, check to be sure you've got
the right card before you start filling it out
When you receive new FSN, unit-of-issue.
nomendalure, etc.. info from support toss out
(or correct, if possible) any pre-prints you
have on file with the old info.

IOAD

Odd Type

Items

If you've got any odd-type
items and you have no repair
parts info on 'em, alert support
ahead of time. That way they can
scout around for supply info be-
fore repairs are needed.

Suspense Files

Keep 'em neat and orderly so
you can easily check requests that
are due a follow-up query. Good
suspense files also help you give
support a complete report on your
due-in requests when they ask you
for a reconciliation report.

Folow-ups

Memorize the
follow-up routine.
Check your local
SOP and para 4-8,
in the AR's Change l.

Everytime you repeat an un-canceled request, your
re-order can be registered as a new demand for the
item at support. That'll eventually foul up demand
data all the way up the supply line.
You can end up with a big load of stuff you don't
need, didn't want, and that you're not authorized ...
to begin with. And, in the process you can create no
end of shortages, costly, time-consuming transfers
and shipment of supplies, plus a lot of other costly
flaps in the repair parts supply business.
The only safe thing you can do on an open request
is to send in your timely followups, or cancel it.

I, ua og
J '-- And, here's a word of caution on canceling. As long as you need
an item it's best not to cancel your request. Here's why:
You can be sure that others are on the waiting list, too. Your place on a priority
group airing list is usually the date of your original request. If you cancel,
you're struck off the list. Then when your new request goes in for the item,
you'lll normal' be placed at the bottom of the waiting list. Para 4-8, in the
AR's Change .1 also clues you on canceling requests.
Remember, a request isn't canceled until you get a "Roger" status card from
whoever o es you the due-out.
It shouldn't take long to get a cancellation squared away when your request
is due out at .our immediate support outfit. But, when support converts your
request to a MILSTRIP requisition (AR 725-50), your request to cancel has to
reach the depot and the status card, confirming your request to cancel, starts
out from depot ... so. the exercise takes a bit longer.

REPRINTS CAREFULLY
THE 3318'S CONCERNEDIZ

Support acriidties now have extra,
special help which gises them up-dated
into regularly. A special DA system
(The Arms Master Data File) gives
them up-dated info on every FSN'd item
in the supply system. All FSN's, you
might sa., now get a health check regu-
larly and support receives the latest
reports.
All support has to do is run some
microfilm rapes or some know-it-all
card decks, and in a flash they have the
goods on any FSN in the Master File.
The SOP on contacts or liaison work
with support is usually set up through
your S4 or unit supply office.

To make the scene, of course, you have to love your constant
companions your repair parts manuals, supply catalogs and
whatever other parts lists you keep.
The listings cost a lot of dough and, the) have only one
reason for existing to help you keep )our outfit's gear combat
ready. So get real close to 'em ... make 'em work for )ou.
First and foremost, read, study, check and re-check a manual's
introduction section. Box, or line in red, or v whatever color
pleases you, any section or instructions, that are of special
interest or importance to you.
Learn a manual's format so you can O MUCH .

How urgent is your need.
Onlh \ou can tell. And, it's to your advantage to tell it right ... eery time.
Here's why:
The Army supply s. stem is geared to support you and everyone else on an issue
priority basis. That means the best support possible for everyone concerned. But.
it also means top priority support for specific items needed to keep essential equip-
ment ready to shoot, scoot and communicate- or, pull its combat-essential job...
whatever it happens to be.
Equipment and items of equipment that uon't directly affect an ourfit's combat
readiness, of course, rate a lower issue priorirn. That's where )ou really have to
play the game right... other ise you'll cause all kinds of grief for .ourself and
create gruesome bottleneck problems in the supply system.
In a nutshell- supply. support must go all out when you send in a top priorir)
request. The) drop evenr, thing and work around the clock to find u hat's needed.
and ship it soonest... b) the fastest means available. That means by high priority
jet plane for man) items.
That's no s cat. The s) stem's set up to respond that a) to urgent needs.
But, when )ou (and too many other supply t pes). accidental. or unkno" ingl)
demand top priority) service on ever) thing you order, support's issue priority oper-
ation gets flooded, over-loaded and bogged down. Eventually your entire suppl.
support system is crippled and slows up as it tries to catch up and dig out from
under. That means all requests are delayed and nobod) gets what he needs when
he needs it.

ABOUT THE F/AD'S
A unit's F/AD is assigned by DA (or a major commander). It's based on the
operational situation and the outfit's mission.
There are 5 F/AD's: I, II, III, IV and V.
But, all you really have to know about them is which one is assigned to your
outfit.

UND'S
There are 4 UND's. They're labeled A, B, C and D. A and B are top priority, C
is special and D is routine. Each one covers specific equipment and the various
urgency of need situations an outfit can find itself in.
It's up to you to know which UND to grab right off, so you can pick the right
I PD for each request you submit. For that know-how, you have to study up on
the UND scoop in the issue priority table.
Selecting UND's, you might say, really boils down to the question: What'll
happen to your outfit's equipment or its mission capability if the needed supplies
or equipment are not immediately available?
You might find that an item may be urgently needed today and rate an A, B or
C UND. Later, the same item may be needed to replenish stocks, or for equipment
that's not essential to the unit's effectiveness, and it'll rate a D.
IAlso, what's urgent for a neighboring outfit today may be strictly routine for

men who have trouble breathing life into the supply codes the% carr And ir's
a shame-because every one of these cards zing with snappy uppl dialogue
for you. And sometimes they expect answers, too.
That's where you come in! With a trusty copy of AR 735-35 (Oct 65) open" _
on your desk, you're ready to meet any status card that comes along. The part of I
the card you talk back to are the columns which carry the Advice and Status -
codes listed in Appendix I of this AR. Just be sure you have the Changes 1, 2 and
3 revisions, too.
Any one of these codes may be punched into card columns 65-66 of the typical
status card, which also carries the same message in printed form somewhere on No matter what it looks like, each status card carries a recent supply decision
that card. which updates or revises a piece of information concerning your supply request.

Every status card carries a two-way message channel in card columns 65 and
66. Status codes transmit decisions made by the supply source for that item down
to you and your DS. Advice codes follow the same path in the opposite direction.
Advice codes should be limited to the occasions when they
are really needed, such as telling your DS what restrictions
should be considered in filling your request. Here are the
,.. ..* most commonly used.

DO YOUR OWN LIST
Some theaters and local supply channels may have slightly different status
code listings which implement and modify those used in AR 735-35. It's your
responsibility to be sure you know all the codes that apply to using units. After
all, you're the one who really needs the item- the supply activities who support
you are just trying to help.
KEEP IN TOUCH
You can also save a lot of time by staying in close contact with your imme-
diate support activity passing information back and forth each time either
one requests or receives status. This cuts down on useless followup requests
for the same item.
The code of cooperation is just as important as the codes on your status cards.

Dear Mr. F. H., l
It's how many times (the number of
transactions) you order this same FSN
that determines if it becomes a PLL item
... and that's 3 times in 180 days. -

difference. One DA Form 2765 = one

And then there's the exception to the PLL rule. AR 735-35 (Oct 65) allows a
major commander to change the usual PLL policy in para 6-6e, page 6-5, of
Change 2 (Nov 68). In other words, he can authorize your oil filter as a "right
now" PLL item if he anticipates a continuing demand for this filter due to

certain conditions within his command.
