You'll also have to check for possible MWO's on major components of your
equipment such as engines, transmissions and fire control items: they might
be listed under the component's publication number rather than under the MWO
number for the major item.
Your command headquarters has a list that'll help line up the current

You enter them on the DA Form 2408-5 or 2409 to be applied.
You'll have to order whatever parts or kits are needed for MWO's your

This dope won't tell you which horse will win the next Kentucky Derby.
But it will tip you off to the right cleaner for the 234 ball bearings that run
around the commander's station cupola upper race ring on your M114A1 Scout.
The plastic balls and surrounding area should be cleaned only with aliphatic
naphtha type II, TT-N-95 So now you know!
Your support will have this and they'll do the job.
For the crew and the company mechanic the only rule to remember is...

/ DON'T FOV-ET '

BALL BEARINGS 12341

Because they're plastic instead of steel, they need no lubrication. In fact,
lube, dry-cleaning solvent and mineral spirits like paint thinner are all bad
for the plastic.
The only time you see these balls is when the commander's cupola is pulled
but you don't need to see 'em to tell if they're working right. If the balls are
on the ball they'll let the cupola spin around quick and silent-like. But if dirt or
the wrong kind of fluid gets to 'em the cupola will operate slower and with
a lot more noise. Then you send it to your support for cleaning.

STEER UNIT OIL FILTER FACTS

The oil filter on your geared steer
takes a terrific pounding, particularly)
when you're warming up a cold engine.
The oil pressure can get so high it
narps the filter container, unseats the
gaskets and even breaks the container
bottom.
If any of this happens you lose oil
pressure and, of course, you can't steer
so good.
So. you need to keep your filter
health) and this is how you do it...

2. Never race the engine during warm up. Instead, you pull the
hand throttle out only enough to get a smooth idle.

3. Let the engine warm up three to five minutes before you
move out.

4. If your situation permits, drive at moderate speed steer-
ing selector in HI and transmission in D until the engine
warms up.

Ml113 PC FAMILY...

GROUSER HEIGHT RIGHT FOR E-A-S-Y ESC

'E N1 N CUR

No matter whether you're putting the tape to a beauty contestant or to the
grouser on your Ml13 PC series vehicle, if you measure from the wrong place
you get the wrong result every time.
There are now eight different TM 9-2300-224-ESC's covering the Ml13
family, but Item 2, the section on track, is the same in all of them. Item 2 says
to measure the remaining steel grouser height from the top surface of the shoe
to the maximum grouser height.
Only question is, where on the top surface of the shoe do you measure from?
Well, the people who wrote the ESC measured from the rib formed by the
inside edge of the sprocket opening to the tip of the nearest grouser, and you
wouldn't be wrong to do the same. 'Nuff said?
MEASURE FROM
STOP OF GROUSER
TO RIB OF INSIDE

The section on track is the same in all the M113 PC family ESC's but some of
the other sections are different so you have to have the right ESC for your par-
ticular vehicle.

You wouldn't drive your vehicle very long without having a cap on the gas
tank. You know that cap's there to keep out dust, sand, water, and just about
anything else that might fly into it if the cap's not on.
There's a spring clip on the M13 gas-particulate filter unit installed in your
M60 tank that does the same job for the filter unit that your gas cap does for
your vehicle.

You have to uncover the air intake openings before you start the filter unit. That doesn't mean you
have to take it completely off just slide it toward the air exhaust end of the precleaner and par-
ticulate filter assembly housing until the air inlet openings are completely uncovered.

Be sure you slide the spring clip back over the air intake openings after
you've turned the filter unit off.
If you don't have a clip for your filter unit, better order one. Ask for spring
clip, FSN 4240-806-0022.

OBJECTS FOUL UP FAN

A little carelessness around the en-
gine cooling fan of your Ml16 cargo
carrier can get you a big repair job.
The size of that fan can build up
enough suction during high speeds
(such as during climbing or rapid ac-
celeration) to suck up any loose objects
left inside the engine compartment.
Naturally, any good-sized object that
doesn't belong there is going to foul
up that fan. In one case, it was a me-
chanic's glove. In another, it was a
broken fan belt. The result was broken

NO! NO! N
DIESEL AND

fan blades, which unbalanced the fan,
causing engine compartment vibration
even at low speeds.
A quick check before putting the fan
access door back would have saved the
fan in each case. Or a homemade wire
mesh screen placed in front of the fan
during maintenance might have helped.
Remember to remove the screen before
operation. This would prevent small
objects from being vacuumed off the
crew compartment seat when the fan
access door is removed.

In case )ou didn't notice, Change 1 IFeb 63) to TM 9-20" .Scp 59) has a
caution thrown in about not adding alcohol to diesel fuel systems.
This caution note is added to para 41a(1) by the change to the TM which
is the manual on operation and maintenance of Army materiel in extreme cold
weather.
The reason for the caution is that while alcohol will mix with diesel fuel,
it can't combine into an alcohol-water-diesel fuel mixture like it does with gaso-
line. Besides, the water is already blocked out by the filters in the diesel fuel
system. So the alcohol really doesn't help to absorb or trap any of the water in
diesel fuel.

Electronic equipment OFF.

transient current surges in
tracked and wheeled vehicles.
The ignition-master switch
combo in tracked stuff, fact is,
has added a iew victim the
AM-1780 amplifier of the new
FM-series radios.
Which takes you way back:
Before you start your engine,
turn off electronic equipment
(with the AM-1780, this means
you turn off the amplifier's
power switch in addition to
the switch on the radio).
Start your engine. If it's a
slave start, keep electronics
stuff off until you disconnect
the slave cable and turn on
the master battery switch.
Turn on your electronics stuff
... and you've beat it one way.
Now, NEVER turn off the
master switch of a running ve-
hicle. Before you stop any en-
gine, turn off all electronic
equipment.
Then, turn off the ignition
switch or press and hold
the engine shutoff switch (in a
diesel, it's the engine fuel shut-
off switch).
Wait'll the engine stops, and
cut off the master switch.
Remember, too, that in all
vehicles you turn off radio
equipment before removing
components from mounts to
keep from getting an arc that'll
burn the pins.

Dear Sergeant G. W. C.,
The direction of electrical current
flow has been, and wil be, a trouble-
some topic. Current to most people is
confusing.
Way back when, Ben Franklin estab-
lished the theory that current flow is
from positive I +) to negative (- ). This
idea is still believed by most people.
When the vacuum tube was put in
use, the positive.to-negative theory
didn't work. In electronic circuits
(radios, transmitters, television, etc.)
the actual flow of electrons (current)

within a tube is from negative to posi-
tive.
Experts are still finding out new
things about current flow. From what
we know now you are right when you
say that "electron flow" (current) is
from negadtie to positive.
In the M-series wheel and tactical
vehicles, the actual flow of current is
not too important. But it is important
to connect all cables marked positive
i+) to their properly marked connec-
tions and the negative( -) cables to their

The big danger in applying the
"electron flow" theory to vehicle cir-
cuits is that somebody who is not aware
of the "negative-to-ground" electrical
system may get the idea that since cur-
rent flows from the negative source
then the vehicle's positive batery cable

signed to operate with positive ground,
but all our M-series tactical and combat
vehicles are designed with negative-to-

So always keep the vehicle's ground

Dear Half-Mast, -.
I'm a maintenance sergeant in a truck battalion and I've got a big tail gate
headache. When drivers unload or let troops out they drop the tail gate and
it gets all banged up.
I've done everything short of swinging a meat ax to get 'em to stop. Do
you have any suggestions on how I can save my tail gates from those costly
repairs? Sgt L. E. M.

Dear Sergeant L. E. M.,
Your headache is an old one. We had the same problem with wagons when in
the hands of rookie mule drivers.
The only other thing you can do besides training is to cushion the gate's fall
- like many other outfits have done.
These outfits attach two 3-in pieces of thick rubber hose on the gate's top
rail with OD tape. The hose is positioned so they'll bounce on the bumperettes
when the gate is dropped. This cushion action does wonders for the gate.

THKK RUBBER HOSE

-,

The pieces of hose are usually scrounged from a junk pile or salvage yard.
The thicker the hose the better. And the cloth backed waterproof OD tape can
be found in any self-service store or supply room. This tape makes the rubber
cushions easy to remove for inspections. II

To replace a Delco-Remy regulator with an Auto-Lite, just install the mount-

r VALVE

Some things are worth re-
peating. This time it's the
valve tappet settings for the
5-ton truck G744-series R6602
engine.
The engine name plate and
the cylinder head decals on the
R6602 say to set the intake
valve tappet at 0.020 inch. TM
9-2320-211-20 (Mar 63) says
to set 'em all at 0.024 inch.
Neither one is right.
Go by Change 1 (13 Jul 64)
to TM 9-2320-211-20. This
change gives the correct valve
settings (Hot) like this:

S01a INCH FOR TH IKEi
0.024 INCH FOR THE EXHASJT.

Make a note of this R6602
valve setting change and stick
it on page 80 of your -20,
right near para 41c(2).

STATIC REEL KAPUT?

A fix for a busted static reel on your
M49C tank truck is simple a hunk
of electrical wire and a couple o' clips.
There're no repair parts for the reel
in the supply system yet, but TB 9-

make sure you've got a safe ground

Wor
I SAID!

Any jockey or cow-poke can tell you that every mount has its own set of
riding traits. Some breeds are meant for a smooth track and others for a rough
trail. And running them out of their bailiwick calls for careful handling if you
don't want to be bucked from the saddle.
Your M151 /4-ton truck is just another mount with its own traits. It's a
trail-rider and is groomed for off-highway traveling; that is, designed for
moving over rough terrain on a tactical mission. It was not designed to be
operated on a highway like a passenger car.
Now don't get the wrong impression-the M151 is a winner on any track
as long as you handle it right.
In other words, all drivers of the M151 should know their mount. A brief
but thorough rundown on how the M151 behaves is covered in DA Circular
385-8 (Apr 65), and a color movie-Training Film 55-3412. Reading this DA
Circular and seeing the movie should be SOP for every M151 driver. The peo-
ple at the head shed feel that no one should drive the M151 until they know
how to stay in the saddle.

Did you know there's a possibility
that you have wrong lug nuts on the
front wheels of your 10-ton trucks?
Wrong lug nuts will gouge the ball

Look your M123's and M125's over.
If you find the rounded radius type,
you're OK.
But if you have the indented tN pe.
you've got to replace 'em with the
rounded type. TB 9-2320-206-12/2 .

SEAR M HAMMER

Of course, this all centers on remov-
ing or not removing the components of
the lower receiver to do the servicing
job.
It's a fact. The 5.56-mm rifle doesn't
like having its lower receiver taken
apart for cleaning- and for good
reason.
The lower receiver's made of alu-
minum to keep the weapon light-
weight. But the pins that hold the auto-

maric sear, the hammer ascmble. the
trigger and the selector lever arc .ll
made of steel.
So. if .%ou keep taking the lower
receiver apart. theic pins'll b..c-n-b-e
makc the holes the. go through bigger
and bigger. First thing )ou knou, the
pins fall out and get lost*- or the
parts they hold won't line up right and
your firing's 'way off.
Truth is, you don't have to remove
the lower receiver's parts at all to do
a good cleaning job, if you do it this-a-
way and do it every day you fire
the weapon:
1. Soak your artist brush (FSN 8020-244-
0153) or other similar type brush real
good with bore cleaner. Then scrub all
the parts like there's no tomorrow to get
off all the dirt and carbon you can.

2. Tip the lower receiver sideways to drain
the excess bore cleaner from the cavity
and then wipe it dry.
/I/

cleaning by riflemen and armorers.
Parts replacement and extra-tough
cleaning jobs are for direct or general
support only.
But, please don't miss out on that
lubing job. All components of the
lower receiver as well as the bolt
carrier group must wear a light coat
of oil at all times. No butss" about it.
Your rifle can't perform without it.
That's why "white-glove inspec-
tions" are too risky for this baby.
There's always the danger that some
guy might be tempted to give his weap-
on a shower or tub bath before inspec-
tion to get rid of dirt and lube.

ar ,LL h .
1-ITE 5.OEE

a~^ t\ ,',oe'T\ f^'i

A cleaning job like this will get rid
of all the carbon and dirt that might
keep your weapon from shooting right.
Any stuff that's left after you do your
level best won't make no never-mind.
Of course, if the lower receiver ever
gets so fouled up that the rifle won't
fire right, then you let support have a
whack at it.
Now you can understand why Change
3 to the new TM 9-1005-249-.14 (15
May 65) no longer authorizes disassem-
bly of the lower receiver group for

Anybody whoi bathri his rifle is d.u
ing it dirt tmo \\o ).. Firt. he's r,''bbing
itr of their lube protei~i.c'n it need'. 2ie.
ond, he's liable to let water seep into
the lower receiver extension. This could
cause rusting of the extension and the
action spring or it might result in a
short recoil of the bolt carrier group,
thereby preventing the bolt assembly
from retracting far enough to strip a
cartridge from the magazine.
When you consider that all this has
a direct bearing on how well your M16
or M16El's going to fire and protect
your hide in a showdown, these angles
make real good sense, don't they?

I'M TOUGHER'N YOU THINK!

Dear Sergeant G, B. J.,
No, the weapon wouldn't have to be scrapped. Your
M14's a lot tougher than you think. In a case of a burn-
out from continuous firing like this even if the barrel
and other metal parts look bad it can be put back in
fighting shape. Replacement of the wooden or fiberglass
parts and a good clean-up job are all it takes.
F'rinstance, you can get rid of the discoloration by
Cleaning the metal with bore cleaner and wiping it off
with an oily rag. Then your armorer can replace the
handguard with FSN 1005-856-2108. Support can re-
S place the stock with FSN 1005-771-4617 and the butt
plate with FSN 1005-690-4067.
The point is, though, that the barrel's metal won't be
Weakened by the burn-out.

YOUR ARMORER SUPPORT CAN AND SUPPORT
CAN REPLACE REPLACE THE CAN REPLACE
HANDGUARD STOCK WITH... BUTT PLATE WITH...
WITH ..

...FSN 1005856-2108 ... FSN 1005-771-4617 ... SN 1005-690-4067

i Of course, if the weapon should happen to get caught
in a fire or such-like, and got exposed to excessive heat for
a considerable spell, the tensile strength of the metal
would be weakened and the weapon'd better be
scrapped for everybody's sake.
26 M-

YOUR M14E2'S HANDGRIP
GIVE HER SOME TENSION

Position's everything in life to the handgrip assembly on your M14E2 rifle
S. when she's attached to the sling and bipod, anyway.
She wants to be slightly forward and held firm in the unlocked position to
the front part of the sling by the sling's second hook.
She does not want to be straight down and locked like this or you'll
wind up with a dead hinge.

LIKE THIS NOT THIS

Y'see, the tension of the sling from the bottom of the handgrip to the front
swivel helps support the handgrip and keeps you from yanking her back hard
enough to bust the hinge when you're firing. This tension also adds support to
the bipod legs .. gives you better muzzle control during automatic firing...
and could help prevent damage if you make a bad landing while going into
the prone firing position.
So, get your baby in her preferred position every time. Put that second hook
through the rung at the bottom of the handgrip. Then push the handgrip for-
ward a couple inches, and finally tighten the sling till you get the tension youwant.

CARBON SHUTOUT
Here're a couple quick-pitches that'll help keep carbon from getting to first
base whenever you're cleaning your M14 rifle and M60 machine gun:
On the M14 turn the spindle valve off. On the M60 keep the gos cylinder up

Bear down on these and you'll shut bore cleaner and oil out of the gas
cylinders .. and lessen your chance of a no-fire. Bore cleaner and oil, y'know,
lead off for carbon buildup during firing.

If you're in rice paddy territory, or any damp climate, rust can be a prob-

means it's cadmium plated to prevent rust.
Until the new baby comes your way, tho, try coating the un-plated bolt with

You wouldn't keep your Huey (UH-1) on the ground any longer than neces-
sary when pulling a Preventive Maintenance Periodic, now would you? 'Course
not.
Yet that's what could happen if any of the transmission oil jets get busted
because they're not pulled right when you take them out for cleaning. Getting
replacements may take time.
Take the "D" Model. The removal poop on the oil jet is in Chap 2, Sect VII,
Para 7-33 of TM 55-1520-210-20 (1 Oct 64). The operation to focus on is
just after you cut the lock wire between the two screw heads.

Remember that the jet flange and barrel are a one-piece deal. Taking out
both screws and using a screwdriver behind the jet flange as a pry will snap-
off the barrel inside the housing. Then you've really got your work cut out for
you!
To prevent this type of revoltin' development, make with your duckbill
pliers on the loosened screw in the barrel. Pull straight out and the jet will
come out in one piece.

Wj EXCEPTION TO THE RULE

SDear Specialist B. S.,
You're stopped-from following the general rule.
There're sometimes exceptions to a general rule like when binding and
clearance would require they be installed opposite to normal.
The manufacturer puts the bolt in opposite to the direction of rotation on
the UH-1B and UH-1D models. This poop should wind up in your pubs soon.
Never guess always follow the installation instructions in your mainte-

When it comes to discovering the source of an oil leak if at first you don't
succeed look, look again.
'Tis mighty important to find out what's leaking, otherwise you could be
wasting time and elbow grease changing the wrong part.
Take the engine oil cooler in your Beaver (U-6). TM 55-1510-203-20P (Sep
64) lists the cooler as a recoverable item. So, it goes thru direct exchange chan-
nels back for repair. The trouble is many of them are A-OK and don't need
repair.
When a cooler is serviceable, the leak is caused by either faulty oil tempera-
ture valve gaskets, or a bum gasket between the valve body and the cooler, sure

BEAVER CARBURETOR GASKET
Dear Windy,
When we removed the carburetor on our Beaver (U-6) there was a gasket
on the adapter mounting pad.
TM 55.1510-203-20 (29 Aug 63) Chap 2, Para 4-356 says a gasket isn't re-
quired.
What gives?
** ------^_____ .V- II

H V H

Dear H. V. H.,
Your maintenance pub is right. You
don't need a gasket because the carbu-
retor and mounting pad mating sur-
faces are lapped to give you an air-tight
seal.
However, if the adapter or carbu-
retor mounting surface is worn or
scratched, it should be re-lapped. A
gasket isn't used because it contracts
and will give you an induction leak
after awhile.
To lap the adapter, put a sheet of
abrasive silicon carbide paper, 320A,
FSN 5350-224-7203, on a flat block.
Rub the adapter mounting surface over
the paper in a figure eight pattern until
you get a flat, level surface.
The surface will be level when all
the dark spots (depressions) are gone
and the entire surface is bright and
shiny.

CATCH THIS COLD
Just a cold weather reminder about
not confusing the Bird Dog (0-1) with
the Beaver (U-6) when it comes to op-
eration of the carburetor air control
lever. Unlike with the Beaver, the lever
on the Bird Dog should not be left in
any of the intermediate positions. The
reason is spelled out in a "caution" be-
longing to para 2-20, Chap 2, TM 55-
1510-202-10.

You wouldn't be getting your fabu-

guys in the outfit.
Even so it'd pay you to remind your-
self to hit these key points just one

and y'think everything's about under
control. a
Watch out for thesepossible defects;:

the locking pin and cam nur. That -"

JUNCTION BOX LOCKING GATE Not hooked all the
way.
Even though the locking arm's secured with
a live cartridge, double-check that the box's
locking gate's latched in the full dosed position.
If it pulls loose in flight, your AGM-22B's gonna
take the junction box with it on a free flight -
a real unguided missile!

EXPLOSIVE BOLT Cables frayed,
shielding broken, connector in wrong.
You 427's keep it connected to
the shorting plug (safe). You gun-
ners connect it to the firing plug
just before take-off. After every
'check, though, don't forget to latch
the cover down to ward off un-
,friendly weather attacks.

Keying your mike before your radio
completely warms up is a good way to
cut down transmitter tube life.
Since transmitter tubes have to be
bigger, with heavier filaments, they al-
ways take longer to heat up than the
smaller receiving rubes. While this is
true for most of your aircraft radios,
it's particularly so for your UHF set
because of the large amounts of power
needed for proper LUHF operation, time
So let's take the AN/ARC-55 UHF Y
radio for instance. The larger air- comn
cooled transmitter rube is going to take earp
longer to warm up than the little re- 15 s
ceiving tube for the same set. The duri
modulator tube provides audio modu- Bi
lation for the transmitter tube and de- tube
serves the same amount of warmup as a

P

ou normally hear receiver tubes

minute or so to warm up to operat-

Sthe panel drop without first disconnecting the
cable by hand will rip the UG-88 plug connector
loose from the cable. The right way is to support
the panel with one hand while you reach in to
disconnect the cable with the other hand.
I / 4 To make it easier, you can ask avionics sup-
port to make you a cable extension the first time
)ou have to remove that access panel. This al-
-.-- lows enough slack in the cable for you to reach

Sure! You can contact the tower on
cold tubes. But any time you operate
transmitter tubes either below or above
their rated temperature range, you
shorten tube life. From the economic
point of view, transmitter tubes cost

More important you weaken the

coating will cause a gradual decrease

ARC-44 RADIO FILTERS...

CASE OF THE DISAPP

ING FUZZ

The RT-294 receiver-transmitter in your AN/ARC-44 FM radio set is sup-
posed to have two fuzzed-up air filters. No fuzz spells trouble.
Depending on which side you look, this filter lays alongside the megacycle
crystal turret or the 1/10 and whole megacycle gear trains.

l DIRECT MOISTURE ... SUCKED INT
CONTACT WITH LOOSENS HOUSING FOULS
MOISTURE. FUZZ... UP CONTACTS.

So if that fuzz starts to powder off one or both filters, it can interfere with the
contacts and relays on either side. All it takes to start the action is some direct
contact with moisture. Even the use of a damp rag to wash off a dirty filter may
lead to more harm than good.
Normal operating vibration and air flow through the housing eventually
knocks off the moisture-carrying fuzz until all you can see is pure screen. The
more fuzz that powders off, the more dirt that's sucked into the housing -until
you really have no filter left at all.
You usually bring this set into the avionics support shop for cleaning every
second PE, But even though the aircraft locations of some R-T housings make it
difficult to inspect the filters, it's a good idea to keep checking between PE's.
Powderless filters require just as rapid replacement as extremely choked up,
dusty filters do.

A 2-HANDED DEAL OR...

HOL

.. tTs::-

Every piece of equipment has its weakest part. So you always handle that
part with care in order not to damage the entire assembly. Same goes for the
base assembly insulator on the belly antenna (AT-701/AR) for the AN/ARC-
60 UHF command radio set.
You can loosen or break this insulation by forgetting to hold the insulator
bushing steady with a wrench before attaching the antenna rod to the base.
Holding the bushing by its flats will keep the tightening torque action from
making the insulator turn as you snug up the antenna rod jam nut.

HOLD IT
BY THE
FLATS.

BELLY
ANTENNA
The base assembly is connected to an impedance matching coil which can
turn freely once the insulator gets loose or broken. The more the coil turns,
the quicker it will snap off ... and then you need a new antenna to bring your
radio back in action.
Sometimes you may want to remove the antenna rod to make it easier to clean
the fuselage and the base of the antenna. But even when you get an oil leak
streaming back along the belly, saturating the antenna base, you can clean up
just as easily with a rag in one hand and the insulator bushing in the other one
.. held by the flats.

WATCH THAT FRAYED BRAID...

NEAT CABLE DRESSING'S NEEDED

Cutting WM-46/U cable for connecting ANGRY-3 through -8 series radio
set components?
Whether installing or replacing, better make sure there's no cable shield
strands sticking out past the bushing before soldering those 10 wires to the
terminals of the MT-297/GR mount and C-375/VRC control box.

LOOSE < ',l NO SHIELDS STICKING
SHIELD /,'^\ OUT PAST BUSHING
STRANDS /

Maybe nothing'll happen right away, but the jarring and jolting of that ve-
hicle can shake the frayed braid against a terminal and short out the radio set.
Clean cable cuts, as spelled out in TM 11-284 (May 53), will help keep that
radio communication .
A free-flying strand from the inner or outer shield of the cable'll make the
radio lose its taste for talking' or listening' like you'd lose your taste for
chicken if it had the feathers on.
While you're soldering the wires to the terminals in the mount or control box
make sure the solder is the resin core kind.
Acid flux is sorta corrosive, like it says in TB Sig 222 (Mar 60). There-
fore, acid flux can't be followed by resin flux and solder ... unless you wanna
flirt with replacing the terminal panel.

IDENTIFICATION LIST
You have Identification Lists (IL) which take the place of your Stock List
of All Items (Type 1 supply manuals) and/or Stock List of Current Issue Items
(Type 5 supply manuals).
Here's a comparison of the old Type 1 supply manual and new IL's:

ML MANAGEMENT DATA LIST (PRICES)
When it comes to the price list, you'll find the Management Data List (ML)
supply catalog takes the place of your type 2 supply manual. You may have
one or several ML supply catalogs superseding the type 2 supply manual.
Here's an example:

X -- CROSS-REFERENCE LIST

You'll also have Cross-Reference Lists.
XL-Cross-Reference List (Part Numbers identified with the applicable Fed-

This is the catalog that replaces the old Type 3 supply manual. Here's an ex-

There's no sweat in telling at a glance the Army supply catalogs from the
Department of Defense supply catalogs. The DA supply catalogs will have
colored covers. ''
The Identification Lists will have green covers. And you can let your fingers
do the walking if you need management data (price, unit of issue, etc.) because
the ML's have yellow covers. The components list (CL's) have salmon covers.
The Cross-Reference Lists (XL) have blue covers.
Don't get too upset if you see some hybrid numbers and some colors that
aren't according to Hoyle. They were some of the first catalogs published.
You'll find the latest listing of supply catalogs and supply manuals "Index
of Supply Catalogs and Supply Manuals," in the DA Pamphlet 310-6 (Mar 65).

KEEP YOUR RECORDS STRAIGHT WITH AN...

OPERATOR'S GUIDE

So you're sending your newest equip-
ment operators 0O miles back of the
boondocks for training and there're
nor enough copies of TM 38-750 or
DA Pam "50-38 to go around.
How can \ou help 'em to keep the
equipment records straight?
One outfit made it easier to train
operators to shape up the records -
like DA Form 2404 and DA Form
2408-1 by extracting from TM 38-
750 the necessary instructions. These
were typed on cards about 6-1/2-in by
9-1/2-in and slipped into the equip-
ment log book.
The instructions can be ryped on the

cards so they'll face the form any time
the log is opened at the particular rec-
ord the operator needs to make an entry
on.
It'll cut down a heap on that old
back o' the boondocks disease. lacka-
kno-how.

NEW FSN TO PBO
Dear Half-Mast, %
Our property book officer says he needs a N.
notice when we apply an MWO that changes S'5-..
the equipment FSN.
We submit a revised DA Form 2408-8,-as
required by para 4-12b(3) of TM 38-750, but -J r-
the control copy goes to the commodity com-
mand as called for by para 4-12d(2). There is
no copy to send to the PBO, so how do we
handle it? \
S\ SFC N. M. P.

Dear Sergeant N. M. P.,
You can dial the PBO and give him the new
FSN.
But para 4-11b(2)(c) of TM 38-750 requires
you to make and submit a new DA 2408-7 when
the FSN of the equipment is changed as a result
Sof modification or rebuild. So, the "control
S copy" of the DA 2408-7 may be forwarded to
the PBO if the local commander approves.

Dear Sergeant R. L. P.,
You win! There was a Change 1 (17 Mar 65) to TM 10-7400-201-10 (Apr
64), Operator's Manual, Office Machines, which deleted the words "weekly
services." So, you don't have periodic preventive maintenance services and you
don't have to keep the DD Form 314. #,01 4

When you fill out those DA Forms
12-37, 12-38 and 12-39 for your outfit's
tank, truck and trailer Pin-Point distribu-
tion of publications, be sure to order
enough for all concerned. For example,
you'll need one copy of the Operator's
Manual, the Lube Order and ESC to go
in each vehicle, plus copies for section,

squad and platoon leaders. You don't
want to leave out anybody. And you'll
check to see how many Maintenance
and Parts Manuals your mechanics and
the parts man need. Circular 310-38 sets
10 Oct 65 as the deadline for the forms
for fastest service.
