- A screw on the loose is about as easy
to recapture as a goosed goose.
STo an body who's ever tried to run
down an uncaprivated captive screw,
the above makes much sense. When the
screws are backed out, like they're not
supposed to be, the) seem to head for
the nearest crack or other convenient
hiding place there to stay lost
Trying to replace many of the captive
screws on common equipment can turn
a supply man's hair white. There are
no FSN's, and about the only way you
can get 'em is to have a general sup-
i port shop make them.
Which brings up the moral: Captive
screws are made so that you don't have
to back 'em out to free whatever they're
holding. So-o-o-o, keep 'em captive.
If you want to insure that they'll
stay captive, try this:
Grab a spare nut that'll thread onto
the end of the screw when it's thru its
panel, door, or whatever. Turn it all
the way up the threads until it flops
over onto the smooth shaft of the screw
. and let it stay there. That wa).
when the screw's backed out, the nut
keeps it captive ... but lets the cover,
panel or door swing free.
Another simple fix is to open a split
washer, slip it on the smooth shaft of
the screw, and close the washer ~ ithh
pliers. An "E" ring or "C" ring pressed
over the shaft will work the same magic.
The big thing is: Keep the screw cap-
tive... the best way )ou know how.
Screws been jigglin' loose, lettin' the knobs on your RT-77( )/GRC-9 re-
ceiver-transmitter pop off?
No sweat. Just get 'em back the way they belong.
You gotta watch putting' on the knobs for the ANT SELECTOR, XTAL-MO
BAND and AF and RF GAIN controls. They'll cut peak performance of that
ANGRY-9 series radio set if they're installed backwards.
For making sure the knobs are on
like they're supposed to be, use the light
Spotting backward RF GAIN and AF GAIN knobs on the receiver section of your set's no problem
cause you have two tests to go by.
First, you'll get only one-half or less of normal sensitivity output; and second, the knobs'll move only
in a 90-degree arc. If they're like they oughta be, the knobs'll rotate 300 degrees or almost in a
And remember... to keep your knob screws from backing off, use a dab of
varnish or glyptol after tightening 'em.
A WRENCH'LL WRECK AN RT

If the spring's weak or grit jams the

So, instead of lettin' it do your FRONT OF PANEL

HERE'S A LIVELY NUMBER
You getting a little run down at the heels trying to
locate the right FSN for the H-161/U headset-mike?
Come out of the supply forest, then, and forget the
FSN that's in the Functional Parts List of TM 11-5965-
262-23P (Oct 62). What you need to shake an H-161
loose up the line is FSN 5965-825-4871.
And since you're in a supply mood over the headset-
k mike, you might remember that its mike and boom as-
sembly can't be replaced via the supply route. Which
I AND BOOM means you cannibalize ... or buy the whole rig.

Using muscle on the stick to overpower the AN/ASW-12 autopilot in the Mo-
hawk (OV-l) can run an avionics section ragged keeping up with repairs.
At least that's the way it was here, until we passed along to aviators a
gentle reminder about all the transistors we were replacing.
What can happen is that the power transistors in the motor drive circuit of
the rotary actuator will fail if the autopilot is overpowered for more than
about eight seconds.
The shear pins in the actuators won't save the transistors, either. The pins
actually protect the bird against any electrical or mechanical trouble In the
autopilot which would cause the gear train on the actuator to lock. If this
happens, muscle power can be used on the stick to shear the pins and give
the pilot manual control.
When making a normal climb or dive, tho, no muscle power is needed.
You use the pitch control "beep switch" on automatic pilot flight controller
To use the pitch control you disengage the vertical engage switch (altitude)
on navigation coupler CU-792/ASW-12(V) and make your move. Then you en-
gage the vertical engage switch again at the new altitude.
Of course if you have to change altitude in a hurry, you can disengage the
autopilot by pressing the pilot release switch on the stick.

Adding a little tit to your tool for bending trim tabs on the Sioux (OH-13) will
also let you measure negative trim.
It's just a minor addition to the main rotor trim tab tool shown in your TM
55-1520-204-20 (1Jun65). But that tit raises the trim tab away from the rest
of the tool enough to let you read minus zero inches of trim along the right
hand side of the tool.
The tab bending part of the tool is about the same as the one shown in the -20,
except that the parts are a little larger.

Dear Specialist L.O.F.,
The bolt should be free to turn in
the horizontal stabilizer bracket bear-
ing and bushings because this action
lessens wear and stress on the bolt.
When the bolt is put in right you
can't tighten the bolt nut to the point
where it freezes to the bracket. That's
because the bolt is a shoulder type with
a step at the head, just past the threads.
The step prevents a tight fit.
If you use a washer under the bolt

let a loaded Huey get away without a
shear pin in the detent rod on each
launcher tube and make sure the
wire's bent to hold it in place when
vibration sets in. The pins ought to be
about an inch long, by the way.
ROCKETS Dirty, greasy, wet; not scarffed; fins, motor tube or fuze damaged; gap
between warhead and motor tube; head closure and nozzle fin assembly and lock
wire protruding from rocket motor tube.
Make like a snake handler with these babies, whether you're taking 'em out
of the shipping cannister, toting 'emf on a Mule or loading or unloading your
launcher. Rough handling causes more erratic rounds than anything else ..
mostly because it busts the motors or bends the fins. A busted motor causes
uneven burning so the rocket could blow up anytime. Fouled-up fins make a
rocket go weaving through the sky like a bat on a binge, climbing and dropping
-maybe dropping on vour ow, buddies out there ..
LET THAT ROCKET
WIT1 TH' FOULED-LIP
A kind thought for these canisters pays off too. If
they get bent, the rockets in 'em get bent, too. You n-ighr
check their covers once in a while to see that they're
lubed and the coil and spring's OK and the padding's
in place. A healthy cannister is the safest place to keep
rockets till you need 'em.
You'd just better protect 'em when the mercury's below -65 degrees or above
150. Otherwise, the rocket propellant won't work the way it should. You could
get a short round and a cold rocket landing on a buddy ... or an explosion from
a hot rocket in the tube.
It'd pay, too, to protect those rockets from the weather
with a tarp when you're stacking or moving 'em.
Incidentally, if you're in action over there, don't make
the mistake of "borrowing" folding fin rockets from a
buddy in the Navy. The Navy type's not scarffed and is
made for use in fast-flying fixed-wing aircraft not
for a chopper. Guys've been hurt this way. So, stick to
the right brand FSN 1340-892-4802-H491, and the BE SURE
ones authorized on page 45 of your -20 TM. THEY'RE SCARFFED
You want to watch it real close if you get one of those motors with a rubber
gasket ring under the lip of the head shipping support and a fiber shim between
the head shipping support and the head closure.
Otherwise, they're likely to swell up and cause the warhead to work loose
in flight. This is a switch on the old system, so heads up, eh?
ROCKET LOADING- Here's the trick to it: Listen for two distinct clicks.
The first'll come when you The second'l be there after After you hear the second

But, if you don't hear that second click you'll know rhe rocket's not seated right

To get rid of the fogging, follow the
scoop in para 24b(4) of TM 9-1055-
217-20 (Apr 64). A pilot can't hit what
he can't see on this subsystem.
Incidentally, if the Huey's going on

won't allow the bulb to be dimmed
enough so's the pilot can see and aim
Junk that doesn't belong on the slip
rings can lead to arcing and this
can be a short cut to short circuits the
kind that melts terminals. When this
happens in your CW acq, the tube and
slip assembly go on the bum.
You can't do anything about dean-
ing the slip rings, but you can get the
word to your support unit to do the
job. And it needs to be done between
50 and 75 hours after the slip rings are
put into use ... and then semi-annually
THIS'LL HOLD 'EM, MAN
Hear tell that loose mounting bolts on
the drive-gear assembly of some Hawk
AN/MPQ-34 radar sets are working
loose and getting people jittery.
Here's how you can keep yours in
place. Get your support people to take
off these bolts (9054224 9054225),
replace 'em with MS-20074-08-10 and
MS-20074-08-11, and then safety wire
'em like it's spelled out in para 20.1 of
These bolts are listed in TM 9-
1430-503-15P/1 (Jun,65) under FSN
5306-689-5679 and FSN 5306-825-
/ WIRE THEM
Then have 'em drill a hole in this
nut (AN335-10) and safety wire it to
This'll calm things down.
Here's the picture.
The Hawk AN/MPQ-39 high power
illuminator was being rotated between
-200 and +400 miles in elevation and
between 900 and 3200 mils in azimuth
when the doppler tracking unit locked.
Everything was OK while tracking
in all other elevation and azimuth set-
tings. What's the score?
It just so haooens that the linuid

antenna when the antenna is rotated
between -200 and +400 mils in ele-
vation and between 900 and 3200 mils
in azimuth. In the cabinet, as you know,
are a high speed motor and pump that
turn out RF energy.
Now if the ground straps and
the RF shield on the cabinet door and
cabinet aren't grounded right because
they're corroded, the RF energy can
make its way through the antenna. And
that's all it takes to lock the DTU be-
cause the RF energy is within the unit's
So what do you do to make sure you
don't get DTU lock? Don't let corrosion
build up on the ground straps and RF
shields, that's what. And make sure the
cabinet door's tightly shut.
CHECK THE ARROW
Another thing about your HPI .
do you have a "bomb" in the radar set?
That's what the high voltage power
supply could be if its pressure relief
valve is installed the wrong way.
S. FACE AWAY
There's an arrow on the valve and it
wants to be pointing away from the tee
at the base of the power supply. If it's
not, call your support people so's it can
be switched around.
With the valve installed wrong, the
freon coolant could be put under
enough pressure to force something to

Xi Who'd think that a coolant mixed

would get hot at the touch of something
like a match.
But that's just what can happen, tho,

GROUND SHORT TIME BRAKES
A big surprise may be waiting for you if you use your M62, M246 or M543
5-ton wrecker's electric brake-lock while you go off up a mountainside picking
wildflowers. When you get back the wrecker's liable to be gone down the
WHETHER YOU HIT THE BUTTON FIRST OR THE BRAKE PEDAL FIRST-JUST MAKE
SURE THE BUTTON'S HELD IN WHEN THE PEDAL IS PUSHED DOWN -THEN RELEASE
THE BRAKE PEDAL BEFORE YOU RELEASE THE BUTTON.
That brake-lock is meant to be used only when you're operating the crane.
It goes into action when you press down on the brake pedal and then push in
the lock button. The brake-lock valve kicks into the closed position, keeping
hydraulic pressure on the brakes. Then, to release it, you just hit the brake pedal.
But you're asking for trouble if you use the brake-lock for ordinary parking.
You may be gone longer than you think, and all the time that pressure is on
your brake system. The hydraulic fluid may leak back or finally ram through the
weakest spot in the brake system. Then no brakes!
Your brake-lock uses current only at that moment when you punch the button.

JOINTS BALL JOINT -NO PLAY!
Dancers, acrobats and contortionists like loose joints, but your M151 1/4-ton
Ball joints in your vehicle's front suspension system carry the weight of the
vehicle. When your vehicle is sitting' with its full weight on the wheels, there's
no play in those ball joints at least, there's not supposed to be. *

And another thing that allowable play doesn't mean sloppy loose. It's just
the difference between two measurements of the ball joint first with the
vehicle's weight on the wheel and then with the weight off the wheel.
Hold 'er again, Newt! You won't
get a true picture if you lift the wheel
off the ground, either, 'cause you'll have
the weight of the wheel on the ball

That little bit of allowable play just when the vehicle's weight is off the
wheel is in the lower ball joint. This's because the wheel weight is on the
upper joint and, besides, the upper joint is spring loaded. There's no pressure
on the lower ball joint, so it will give a little.
UG LOOSE YOKE
Should the front and rear differential U-joint yoke (FSN 2520-745-7745)
on our M151 1/4-ton truck be loose when the yoke bolt is tight? Will a loose
yoke cause any U-joint damage? SP5 F.A.D.
Dear Specialist F.A.D.,
The yoke should fit tight on the
spline. If it doesn't then it's more'n
likely due to a loose plug inside the
yoke. The wobble caused by a loose
yoke will wear the U-joint real fast.
So if the bolt is tight but the
plug is loose then you need a new yoke

PINTLE LUBE FITTING
SDear Half-Mast, I
Where does it go?
The item In question is the pintle
lube fitting on our 2-1/2-ton 0742
series trucks. Some of our Reo's have
the pintle attached as shown on page
115 in TM 9-2320-209-20P (Apr 59).
This puts the pintle's lube fitting be-
hind the frame where a grease gun
Other trucks have the lube fitting
on the outer side of the frame. Lubing
this one is no problem.
Can we change all the fittings to
the outside position?
_. .SP5 D.RDJ
Dear Specialist D.R.D.,
SYes. The -20P showing the lube
fitting behind the vehicle frame has
been superseded. Page 161 in the new
-20P dated January 1965, shows that
the fitting goes on the outer bracket.
Every G742 series truck should have
its pintle lube fitting on the bottom of
the outside bracket. Just like the new
opecaor's manual TM 9-2320-209-10
(Feb 65) shows on page 163.

THE RUBBER SQUAD...
Battles aren't won with vehicles
alone but a lot of battles couldn't
be won without 'em. The day of all
push buttons and robots isn't here yet
and when the day does come, a lot
of those robots will run on wheels.
So, for a long time to come you and
your vehicle carry a big responsibility.
Without you and your truck, a lot
of guys won't get where they're sup-
posed to go or won't get the supplies
and other stuff they need when they get
You're responsible for a real organi-
zation when you're gripping the steer-
ing wheel of that tactical wheeled ve-
hicle. That vehicle is a whole lot of
parts "organized" to do a certain job.
And your "organization" depends on
a real hot-shot squad to do its mission.
That's the "tire squad." Without those
tires, your vehicle isn't going anyplace
- at least, not very far or very fast.
So you're the "squad leader" for
those all-important tires. Your "squad"
may be made up of anywhere from five
(including the spare) to 11 tires, de-
pending on whether you've got a 14-

You'll leave a trail o' wasted rubber behind you, too, if your vehicle's got
such aches and pains as wrong turning alinement, sprung axle, faulty wheel
bearings or troubles in the brake drum, wheel or spring.
What's your clutch got to do with your tires? Well, if your clutch is the
grabby kind, it starts you off with a jump one of the quickest ways to burn
some of the rubber off your tires.
LOOK 'EM OVER
So your tires all look ready 'n' willing huh? From a distance, that is but
how about close up?
Bulges in casing
S Nails or other sharp ob- Stones wedged between
jets imbedded in tread? the duals?
Now you've given the eagle-eye to every member of your "squad" but
one. That's you the leader (also known as "equipment operator").
THE HIGHWAY? ROUGH ROADS WITHOUT MOTION?
NOW, WHEN IT COMES TO MOUNTING...
There's no need to lose your head which you can do if you're not careful
- when mounting tires on rims with locking rings. Stick to the directions, as
given in TM 9-1870-1 (beginning on page 63 for these rims), and the rings
shouldn't give you any trouble.
... IF NOT INFLATE WITH RIMS
I INFLATE AWAY FROM BODY
... OR USE A SAFETY CHAIN...
L I | ^iJYi~flJL I
Play it safe, too, by making sure you've got the right rings for the rims.
And steer clear of rings that're damaged or badly rusted so they don't fit snug
- and stay snug.
Get all the air out before you start taking the tire off the rim. And when
you're assembling the tire, rim and ring, put in only about 5 pounds of air -
or just enough to shape and seat the tire. If you have to tap the ring into place,
you don't want a lot of pressure behind it in case it pops out.
Plain bar soap rubbed on the tire bead will make the tire and rim go together
easier. Oil and grease are out they'll ruin the rubber.
Translated it means Know-How Plus Tools equals Preventive Maintenance.
You say you have the know-how but may be missing some of the tools.
If it's the No. 1 Common Organizational Maintenance Tool Kit, FSN 4910-
754-0654, you need to check, here's your guide.
Remember, a difference in the manufacturer may make a difference in the
way a tool looks but not the way it works.
You get one each of the tools unless noted.
You'll find these tools in SM 9-4-4910-A88 (Feb 63) and its three changes.
No need to look for the air compressor, FSN 4310-752-9633; it now has its
own Line Item Number in your outfit's TOE.
