AIR
MOBILITY

A spark plug bin with nothing in it
is starvation for sure.
Aircraft don't fly without spark.
But there's help in that spark plug
cleaning kit like your FSN 4910-"86-
9271, Type TK-2, in your organiza-
tional maintenance A, B and C tool
sets. With a kit, any plug that's
basically healthy can be put back to
work.

rels, or electrodes chewed halfway off.

and guck from plug bases and make
your pressure-cleaning compound last
longer. Steer clear of carbon tet and
gasoline and use lots of ventilation.
Whenever you use solvents, you want
no fires, smokes or matches around.
You can put plugs in a metal tray
(fabricate one as you like it), and give
'em a bottom-end bath in solvent.
About 15 minutes should do the
trick. Then turn the plugs over in the
tray and dry 'em with compressed air.
Before applying that pressure, protect
yourself with safety goggles and gloves.
Don't be tempted to hold the plugs in
your bare hand while drying 'em. Com-
pressed air is dangerous when shot at
your skin.
DUNK 'EM IN SOLVENT

Trichloroethylene vapor is toxic,
which sort of rhymes with sick, a kind
of sick you prevent with ventilation.
You want no fires, smokes, or matches
in the area.

ON THE BUSINESS END
Now check out your cleaner kit,
make sure your water trap on the
air supply line is good, your cleaning
compound is dry, plentiful, and not
over-age ... and you're going good. If
your compound is shy, take off the door
and take out the container. Pour in
pure AC type CL-3 Aircraft Spark Plug
Cleaning Compound... about half a

fresh package is right. Never use sand
or gypsum powder. Replace your clean-
ing nozzle with a fresh one (part CL-73)
every time you replace compound. Then
put door and container back snug.
On this outfit, you have to make sure
you're grounded. If your electric supply
isn't 3-wire with ground, then hook the
whole case to a standard ground rod or
water pipe.
Now sort out your plugs .. Put
the right adapter for the bunch you'll
work on first into the pressure-cleaning
rig, lock it in ... and here you go, first
plug in place.
You push down the compound blast
lever with one hand, and wobble the
plug with the other (holding the plug

WOBBLE THE
PLUG -
DON I TWIST

in, natch) for about 5 seconds. Then
take a 5-second plain air blast cleanup
to blow out compound particles.
Then's when you hold another small
CMMI of your own- get the firing end
of the plug under the AV24-1 inspec-
tion light and scan sharp-eyed. If you
see carbon or anti-knock deposits up in
CHECK FOR LEAD AND OIL FOULING

-a

the cavity, set the plug aside for a trip
through your vibrator tool-AV19-3
by name.
If the firing end isn't badly leaded
or carboned, another short compound
blast and air cleanup could be enough
... but not a long grind. That just
chews up electrodes and porcelains.
Whatever you do, that compound,
every speck of it, has to come out of that
plug base before you even think of
reinstalling in an engine. Nothing on
earth is deadlier on polished aircraft
cylinders than that abrasive.
USE THE VIBRATOR
Several plugs will likely be black
up inside. Your vibrator, which looks
like a small smiling alligator with buck
teeth, fits right up in the shell.

RECOGNIZE
ME?

It's simple. You pick out the right
tool, take each plug between your
thumb and fingers, and rotate it gently
while running. On 3-electrode plugs,
use paired tools CL-273 and CL-274 in
a CL-272 holder.

Soon's the tough ones are thru the
vibrator, run them back for a com-
pound and air cleanup. Then all you
have left is barrel run-out and re-
gapping.

THE OUTSIDE END
Barrel cleanup is an item you can't
be slack about. Electrical leaks there can

GA, ;K

BARREL/

be disastrous .. and a dirty barrel is
a leaky barrel.
So put the sleeve cleaner in your
bench grinder chuck, use AV7-1 cleaner
compound like creamy soap, and make
with a gentle ream-out. Then comes
dishwashing; all that soap has to come
out in plain old good 'n' warm water.

GIVE IT
A FINAL
INSPECTION.

Air blast drying is the finale. And right
then is a good time for another short
inspection.
The thing is, breaks you couldn't see
for dirt may show up when you get
barrel insulation nicely cleaned. That's
one reason you do that barrel shine job
in the first place--so you can see what's
what.
GET THE GAP RIGHT
You have a set of spacer gage leaves
to take everything up to 21 thou-
sandths. Follow your TB 55-2925-200-
25 (Feb 66), and be sure you have not
left any wire brush bristles inside. Then
check the gap. For flight engines, the
gap is .016, that is, 16 thousandths.
You can have a thousandth over or

under, but two thousandths over is
NO-GO.
For AC 172, AC 272, SR47P and
REL38B plugs, a gap of .019 is right.

CORRECT GAGE
LEAF WILL
GIVE YOU
CORRECT GAP

That's all there is to it... but do be
sure you gap all the plugs you clean.
Looking at them and deciding they
don't need gapping could conk an
engine.
WELL THEY
LOOKED
OKAY/

RNAL INSPECTION
You need to make sure of your work,
of course, and this kit even includes a
little giant handy checkup, otherwise
called the indicator portion.
Pick the right size adapter for the
plug to be tested, run the plugs in just
finger tight (you have to have a little
bit of air leak for the tester to work
best), and hook on your connector.

Next, get the high-voltage contact arm
onto the exposed terminal, and take
your hand offa the works.
Reach over by the indicator gage and
push the high-voltage button. If your

> r~ e -

plug is healthy at all, it'll flash fire, and
you can see it reflected in the gage
mirror.
Now put the air pressure to it .. .
open air control needle valve gently,
and let pressure build a bit. See if the
plug still sparks; as the gage needle
goes from red to green, do you still
get good fire?

HOOK UP OPEN AIR
CONNECTOR CONTROL VALVE
Several things could happen. You
might see sparks run all up and down
the center porcelain, but unless one gets
"stuck" in one spot, mox nix-that
high voltage current wanders around
like thunderstorm lightning. What you
want to be sure of is, the spark on the
plug tip doesn't dim out and an arc
doesn't develop in one single spot away
up inside the throat... if it does, you've
found a break in the porcelain, and out
goes the plug.

QU ICK! GET,
THE DOC! IT'S
ARCING UP
IN THERE!

You could get a spark at first, then
it could stop before your needle ever
gets out of the red-and you'll know
that if there's nothing left in the throat
by accident, and the gap is right, that's
a bum plug, too.
In fact, if the spark stops but your
dial still registers, no matter what the
air pressure is, you've probably got an
invisible insulation crack some place-
so take no chances with that plug either.
The same troubles could be in the
barrel insulation. A fine crack there
could be draining your current. So be-
lieve your gage pointer, and the rule
is-

SPARK PLUG HEALTH HINTS
You won't be doing anybody's en-
gine a favor if you reinstall plugs that
haven't been brush-cleaned at the base.
Those threads take on a lot of carbon
and lead guck. A rotary brush in your
chuck, .005 wire size, and a careful

BRUSH
CLEAN
THE
BASE
hand-held run-through, will do the job.
If you've got a slow-turning motor,
1000 to 1725 RPM, that's good.
Checking gaps before you give plugs
a thumbs-up is another good rule.
That's what your GO-NO-GO round-
wire gages are for.

Your magnifying glass will help you
see whether any fine breaks in sleeve or
tip porcelains might have sneaked past

And before you store plugs for later
use, best pickle those barrel and shell
threads in an oxidation inhibitor, MIL-
C-6529-A, Type III. While you do that,
scan the threads real well to see that
none of them are roughed up and likely
to damage your engine; if in doubt, get
your support to check 'em with a thread
gage. Damaged engine cylinder head
bushings is one item you can do with-
out.

-2XZ"t-' BY THE NUMBERS
You should have received a TM 9-4910-422-12 (Jun 64) with your kit; if not,
get one ordered on a DA Form 17. It has all the factory part numbers and FSN's
you could dream about. / UST IN CASE

I PROPS `-- PITCH

Basic Beaver (U-6A) props P/N 2D30-301 and 2D30-237-6101A18 have the
same diameter-8 feet, 6 inches-and a pitch range of 10.5 to 24 degrees at the
42-in station. You may have prop, P/N 2D30-237-6101A20, which is 2 inches
shorter in diameter and gets a pitch range of 11.5 to 24 degrees at the 42-in spot.
Better check your props and pitch ranges 'cause a wrong pitch setting could put
your Beaver-bird in a bind.

Mayday! Mayday! from pilot or troops gets faster action than Cong from
Mini-the-gun. Successful rescue from Cong or crash may depend on how well
you've pulled PM on your distress marker light-FSN 6230-067-5209, P/N
SDU-5/E.
This 8-oz strobe light is about as caretaker-free as can be. Usually the only
upkeep is replacing the battery when the light needs a shot of adrenalin. But
giving the light a PM check-out once in a while is playing the game according
to Hoyle.
PM CHECK LIST

Check the date of manufacture CHECK DATE
of the battery. If you think a bat-
tery has been in your light two
years or longer, replace it with FSN
6135-073-8939, P/N MSS6135-
IC. Cost: $2.50. PiE

Take a look-see at the battery -
for cracks, dents, leakage. You'll
know a leaky battery by the strong
pungent odor that smells like A PLAIN OL'
vomit. UGH! Bum batteries get ERASER DOES

sion. A pencil eraser does a bang-up
Mr. Clean-type job here.

If \ou find corrosion
or rust, a wire brush
treatment is in order.
Add a dab of silicone
grease to stop crud
build-up.

Notice the glued-on
O-ring? Is it cracked,
broken, loose? If so, you
may not have a water-
tight light. Replace bat-
tery if you can't find

So-o-o-o, if you're an OV-1 pilot who

a preventive maintenance inspection--
and washers are no exception.
For one, be sure \ou focus on the
chamfered washers, FSN 5310-925-

ment.
If the clevis doesn't appear to be
centered on the mixing arm the washer
is shot.
Keep the washer wear pattern in
mind, say, every 4th periodic. You can
replace worn washers for peanuts.

You guessed it. On the maintenance

M16A1 RIFLE

ADDED LSA
INSURANCE
.lW2.aMr,

Oops, hold one there, you sure-shootin' M16AI zapman.
Before you head out on patrol or even to the firing range, add this one bit of
LSA-type insurance to your weapon. WHAT WE MEAN
THIS IS WHAT WE MEAN
Put a very light film of LSA inside the BY VERY
bore, the chamber and on the locking lugs Put some LSA on a swab, LIGHT!
... after you clean 'em good and get through squeeze the swab out till
with the other before-firing cleaning and lub- it's just moist...
ing chores outlined in paros 3-7 and 3-8 of
TM 9-1005-249-14 (1 Aug 66) w/4 changes.

The film of LSA it leaves won't interfere one bit with your shooting, but it
will protect the pas against corrosion-especially, if for some reason you
don't get to fire off.
The next change to your good book will have a word on this.
Meantime, remember: Cleaning and lubing before firing go together like a
go-go girl and a cage.

Dear Half-Mast,
Some of the M16AI rifles in our outfit have letters stamped on 'em to show that
they've been chrome-plated. Does this mean they don't need as much cleaning as
those not chrome-plated, or what?

Dear Specialist F. C. E.,
Kill that idea quick, Man! Every
weapon ever made needs the best clean-
ing job you can give it.
If your M16A1 has a C, or RNC or
RUC stamped 1 inch from the flash sup-
pressor shoulder, it means the chamber
has been chrome-plated and that's
all. Not the bore, or any other part.
This chrome job helps keep the cham-
ber area from getting pitted or cor-
roded... a real good deal. It will not
keep the chamber from getting powder-
fouled or otherwise gooked up.
The dirt'll get in there same as

SP4 F. C. E.
always, and it will still foul up your
firing if you don't get rid of it real often.
Matter of fact, after a weapon's been
fired for some time, you can't tell by
looking whether its chamber's been
plated or not. Either way, give the
chamber the cleaning job the TM calls
for. And keep the habit of eyeballing
the chamber area after you clean it for
any kind of damage.

BORE NOT CHROMED
Once more, the bore is not chrome-
plated. Clean it extra carefully-and
keep a sharp eye peeled for pitting.

H~~-A~

looks can be deceiving. battered bolt, ruptured cartridge or
unextracted cartridge. And too little
headspace in the other weapon can
IDDBIIAL make it tough to chamber a round.
DONT BT So ... please not to switch bolts-
ON if! either on purpose or by accident. And
you can make the switch accidentally
What your eye can't see is the hair- by mixing your disassembled parts with
width difference between bolts for the another guy's-like when you're clean
same weapon--the kind of difference ing the weapon.

You know it... you leave the job of removing the
butt plate from your M14 rifle to the man in your HANDS
support unit. OF
And now that the M14 is getting a plastic stock,
it's even more of a must for you to keep a screw-
driver, knife blade or what-have-you dear of the
screws-especially the top one--that hold the butt
plate fast.
Seems the top screw goes into a nut and retainer
nut in the plastic stock. With the screw out, the nuts
can get lost. And when this happens, it's a job for
your DSU to replace them.

NEEP SOME
SIGHT ADVICE

~j~AI6P Hirs UIr

Even a seeing-cye mutt can't help
you if you let the elevation sight scale
on your M60 machine gun get bent or
busted. And this aluminum part is the
No. I patsy when you're careless with
your weapon. So-o-o-o...

1. Always loosen the range-plate screw
before you move the scale up or
down. And tighten it reda snug after
you've found your setting. \

2. If the tadicad situation permits,
always fold the sight down flat when
you cany or haul the M60, and any
time you lift the cover. You don't
have to danger the sewing to do
this, either.

3. Always fold the sight dwn flat be-
fore you put your weapon in a
vehide-ond he mighty careful
how you put it in the vehide, too.
Never pile one weapon n top of
another. I- %

bly does get banged up, get DS on it,
pronto. They're now authorized to re-
place busted parts.

COUPLE OF LAPS

ThAT'LL SAVE YOU.

Are the socket-head cap screws (re-
taining bolts) loose?
Those would be the ones that hold
the elevating and traversing assembly
to the tripod on the M79 mount for
your M40A1 106-MM recoilless rifle.
Your support people can take care
of 'em by latching onto a 10-CC plastic
bottle of sealing compound -the kind
that comes under FSN 8030-081-2339
on page 73 of Fed Cat C8000-IL-A
(Jan 68).

They'll remove the
screws and lock washer
...clean the screw and
hole threads with dry
cleaning solvent. Put new
lock washers on the screws...
and then coat the screw threads with the
sealing compound. After the screws
are put back and tightened, you're in
business.

GET 'EM STAKED

He%, reckless rifleman, take a minute
right now to ee-check these 6 screws
in the receiver of your M8C sporting
gun. Loose? Missing? Not staked?
They're apt to work loose after a lot
of firing if the wrong screws are in
there and if they're not staked. Get your
DS to replace any loose screws with
socket-head cap screws (FSN 5305-389-
81331 and to stake each of the 6 screws
in 2 places.

You could cause a misfire if you hooked up a rocket in the launcher with a
damaged firing wire or a disconnected disc on it.
Here's the safe way to do it: Lift up the looped end of the retaining wire,
then push it forward and away to unhook the other end -making sure neither
end catches on that firing wire or the contact disc.

Then, never forget to check the condition of the firing wire and disc as you
load the rocket in the launcher.

M113A1 CARRIER
SMOOTH
OPERATORS
NEEDED

YOU ARE?
SO LET'S
SEE HOW
YOU DO
WITH YOUR
ENGINE .
^d

A smooth operator always knows just
what to do, whether he's making out
with girls or keeping the blower drive
shaft on his M113A1 engine from
breaking.
The smooth operator sees to it that
his M113A1 engine is adjusted so it has
a gentle idle. A rough idle puts too
much strain on the shaft.
Likewise, he lets his engine warm up
3 to 5 minutes at 800 to 1,000 RPM
before he moves out and he gives it a
2-minute cool-down period at 1,000
RPM before he shuts down.
He does these engine and shaft-
saving things because he operates his
vehicle like it says in Change 1 (Oct
65) to his TM 9-2300-224-10/2/1
(Sep 64).
A SUDDEN
TORQUE ,\
CHANGE....

A smooth operator always keeps his
air cleaner clean, since a plugged air
cleaner puts a fatal strain on the blower
drive shaft.
One thing a smooth operator will
never do-he will never, but never,
stop the vehicle engine by pulling the
fuel cutoff out and letting the vehicle
coast to a stop. This sudden change in
torque can break the shaft.
The new and tougher shaft, FSN
2990-903-0908, will also break if
abused. (It is made weak on purpose
so it will break and save the blower
and/or engine.)
If this happens, send out an EIR on
DA Form 2407.

Aside from these danger areas you
can, of course, both traverse and shoot
at maximum depression.
The thing to do is traverse gently at
different elevations until you get a feel
for how low you can go in various posi-
tions before iou hit something. Sort of
file that away in your memory like you
hate already done with the location of
the interrupters.
Not understanding how the inter-
rupters work is the other thing that can
foul you up.
As iou already know, when you tra-

2 places where the gun stops like a
balky mule and will not go ahead until
you press the red o'errind button near

the 2 interrupter points are closer to-

Another thing, each individual vehi-

placement of its interrupter stops, so

These stops are a warning to the
track commander that his observer
might be in danger of gearing clobber-
ed. The TC should nor press on the
override button until he is sure the gun
barrel is riding high enough to clear
both the observer and the observer's
machine gun.

This system will work OK if everybody remembers that each stop gives pro-
tection from only one direction.
After the override button is pressed and you continue traversing the gun in
the same direction, you will pass through the opposite stop without knowing it.
This stop will work only if your gun barrel "hits" it while moving in the
opposite direction.

DErUIKLE ur. HILL V

This is the way to remember it .... Once you have pressed the override for
either stop, neither stop will work again until it is hit by a gun barrel traveling
in the direction it protects for. A gun barrel going in the opposite direction
would pass right through the position without being stopped.
'Course, actually the stop action is done by a cam but the position of the gun
is what you have to think about so you can clobber the Bad Guys instead of your
buddies or your own vehicle.

can be a little off when the reflector is
reversed.
To keep 'em the same, put a small
piece of tape on the back and at the top
of each half so's you can see or feel
which side is which when you're re-
installing 'em.
On the CX-8666 remoting cable, you
should never put it on the ground unless

the dust cover is on the connector. With-
out the cover dirt or sand can get inside
and short 'er out.
Also, in hooking up the CX-8666 to
the remote cable connector plug take a

look-see at the color coded (orange)
ring. If it's showing you know the con-
nector is in place and the pressure lock
has a good grip on the plug.
Then there's the battery cable. It too
has the color-coded pressure lock to
insure it's secured to the RT's battery
connector. CABLE

But, when the battery cable isn't in
use, keep it snugged up to the dummy
plug on the bottom of the CY-3871
battery box. This'll help keep the con-
nector clean and dry.
And, you say you have to pull the
end cap and storage bracket out of the
MX-7565 tripod column assembly and
lay it down every time you set up the
MT-2958 radar tripod.

Then, loosen the leg locks and swing the

Dressing up the Pipsy-5 with a PP-

One last tip...
Keep dust caps and covers on con-
nectors and plugs. A dirty connector
can short out your Pipsy.

LUBE IT L QHTLY

More'n likely you won't need more
than 15 to 20 CC's to bring the oil level
even with the bottom of the front hole.
That's what it takes for proper lub-
ing.

When you lube ... be careful.
In refilling your drained AN/MPQ-
4A radar set's scanner gear motor gear-
case, watch it. Better guard against put-
ting in too much oil.
Too much'll cause leakage and dam-
age to your oil seals.

Don't sweat it. '
When this blooming occurs in your set's IP-795 radar target indicator, pull
the plug.
That is disconnect the 5W6 cable's P2 plug on the CV-2093 signal data
converter-restorer from the 9A2J3 video jack of the R-1335/G or radio receiver.
Leave it off until you're sure a data signal is coming in, then reconnect 'em.

When you have your mitts on one of these longlife batteries go easy about

tation and storage life, and do not need to be kept in the cool, anytime.
While they're not in use, they sleep--pretty much holding their rated hours
of service life. This being 40 hours for the BA-4270 as compared to its team-
mate, the BA-270, with 24 hours at best, and 55 hours for the BA-4386, com-
pared to 30 hours for the BA-386.
To make sure you know you have a magnesium battery, the shipping, inter-

You might latch onto a clairvoyant,

-but preliminary PM by the old per-

the AN/PRC-6 radio set.
To keep your Perk-6 full of person-
ality and at the ready, you'd certainly
never stretch that new looped handset
cord, just to see how far it'll go. The
curly-cord could lose its snap.
You'd remember to remove your BA-
270/U battery, or BA-4270/U long-life
battery if you meant to keep your set
out of use for a time.
You're extra careful with the sub-
miniature tubes along both sides of
the receiver-transmitter no break-

And you'd never turn the discrimina-

If the small tube pins break in their

turn to the left to open it, a half-turn
to the right to close it. Too much turning'

Always shut the engine off with the

1/32-in diameter, Code 81348 No.
QQS571, for use with your Pershing and
Sergeant guided missile test sets? Ask
for FSN 3439-555-4629. You'll find it
listed in SC 3432/70-IL (Jul 67).

W&uti6ued MWO
Your starter gets MWO 9-2920-248-
30/1 (Dec 67) if you've got a 2-1/2-
ton truck with the LD 465-1 engine or a
5-ton truck with either the LDS 465-1 or
LDS 465-1A engine. Your support will
fix up the solenoid to save you starter
troubles. (Catch the slip in the MWO -
it should be Starter Assy, FSN 2920-
999-6216.)

Your M17 field protective mask must
be a good fit... and it's especially
risky to wear one that's too large. Could
be you've been issued a medium (FSN
4240-542-4451) or a large (FSN 4240-
542-4452) M17, when you need a small
(FSN 4240-542-4450) mask. So test
yours out for the right fit like page 22
of TM 3-4240-202-15 says.
