Fuel is to your
equipment's
engine what food
is to you.


Food makes you go; fuel makes that
engine go.
You never want dirty or spoiled food;
it can make you sick or even kill you.
It's the same with that engine. Dirty
fuel can make an engine mighty sick,
even kill it... especially if it's a diesel
or multifuel job. Those babies have
powerful muscles, but weak stomachs.
Dirty fuel is knocking a lot of 'em out.
_-. t-


That's why it's real important for you'
to see that only clean fuel gets to your
engine.
There's one way to make sure your
engine drinks only clean fuel, and it
takes just minutes a day. It could pay
off big for you ... like seeing that you
get through a real tough situation.
It's this: Drain your engine's fuel
filters every day. And, drain the fuel


tank scic week or so. depending on
how ct your climate is. The warmer
and werrer the climate. the more likely
.our fuel is to get ill gummed up v ith
bacteria and such scum. See your TM

An air defense guided missile system

That doesn't mean iou forget it's around until iou go to use it. Nor on sour

happen before and after iou squeeze the trigger.
So come along on an inspection trip around sour weapon, the sort of trip t.
that can help iou head off trouble at the pass. As you check remember that the ,.
points in hold ispe want to be taken care of right away. .-f '
If you have a humidity indicator plug in the batten /coolant unit receptacle

The from window is broken.
Bits of the broken window can
form a wedge between the missile
and wall of the launcher--a
wedge that might cause the mis-
sile and launcher to leave your
shoulder if you try to fire the weap- ,A \,
on. Believe it.

You don't have to treat your weapon
as if it were a crate of eggs.

I'M KEEPING
7 IT -AFE.... .
\ SEE.! r. I


o"I if you toss it up on the
floor of a truck and knock the different
interior components out of whack, the
weapon will be safe. Trouble is, and
here's the clinker, you'll wind up with
just so much metal, plastic and what-
have-you in your hands.
And what good is a safe weapon that
can't do its job? It's like digging your-
self a hole 200 feet deep. You'd be
safe, but you wouldn't be hitting back
at the enemy.


So try to keep your missiles in
their container when you're on the road.
But, comes an emergency, if you and
your Redeye are together in a vehicle,
carry it on your legs to keep it out of
harm's way. If you can't carry it, put
something between it and the floor of the
truck-like sleeping bags or blankets.


L HINTS

Whenever you put it on the ground,
make sure-- doubly sure-- that it's on
its right side-with the bumpers fac-
ing down. The bumpers are the only
things that should touch the ground.
Always carry it with the seeker end
skyward.

down.
PUBLICATIONS
One thing you have going for
you is the publications for Redeye
-TM 9-1400-426-12 (Aug 66),

not loaded with pages, so you won't
get bogged down in reading. But
Ithe scoop in them is real important.

RI G'S THE 0 M I9G
An ounce of prevention is worth it when it comes
to applying MWO 9-2300-216-20/7 (Jun 66) to
your M107 SP 175-MM gun or M110 SP 8-in
howitzer. 0
The MWO has you trade the two parking brake
pins in the parking brake assembly for stronger
ones. You don't get new plate retaining rings with .
the new pins, though, and the chances of busting
the rings when you go to remove the old pins are
better than even.
So look ahead-have extra rings on hand before
you take care of the MWO. They're on page 77 of
TM 9-2300-216-20P (Jul 62)-under FSN 5340-
720-8064 and FSN 5340-715-1152.


A VIAL THOUGHT
An M118 elbow telescope level vial that you
can't read sure does you no good.
Maybe you've already found this out-if
you're with the crew of an M108 105-mm SP
howitzer or an M109 155-mm SP howitzer.
So happens that moisture and dirt can get
down under the level vial. And enough of this
unwanted stuff will keep the light from coming
_._ through to the vial.
There's a way out, tho.
Your support people can seal along the edges
I. of the vial with locking compound-the kind
that comes in a couple containers under FSN
8030-275-8110. It's in Fed Cat C8000-IL-A
,. (1 Jan 66).


'V PLAIN TO SEE
You're right .. putting white paint on the rotat-
ing head of your M117 panoramic telescope does
make it easier to spot the head when you're sighting
on an aiming post at night-whether your shooter
is the M108 SP 105-MM howitzer or the M109 SP
155-MM howitzer.
When you do, though, you're going against the
rules. As it says on page 44 of TM 9-213 (Jul 62)-
Painting Instructions for Field Use-"The part of
the telescope or other fire-control equipment that
extends outside of the tanks will be painted olive-
drab." That also goes for other tracked vehicles, like
your SP.
Painting the head white makes it easier for the
other guy to see. And it means somebody will have
to paint it again--with OD.

COOKING WITH GAS


Have you taken a gander of late
at your Nike-Hercules launcher gas
cylinder?
The cylinder is given a hydrostatic
test by your support unit every 2 years.
You find out when the cylinder was
last tested by checking the date on the
cylinder.
'Course... if the cylinder looks beat
or maybe is corroded, don't wait 2 years
to shoot in a DA Form 2407 so it can
be tested. Do it now.


PLATE TELLS ALL
Why guess at what you're supposed to do when it comes to filling and drain-
ing the hydraulic reservoir for your Nike-Hercules launcher?
If the instruction plate for the reservoir is missing (seems a number of
launchers made it into the field minus the plate) ask your support unit to
make one for you. The scoop on putting the plate on the launcher base frame
is in MWO Ord Y75-W63 (Apr 60).
You might mention to your DSU that
in making the plate, the drain instruc-
tions should tell you to remove and
replace the cap, not plug. MWO Ord
Y75-W78 (Aug 63) changed the plug
to a cap.
And instead of being torqued to
400 in-lbs, as with the plug, the cap
gets torqued to 270 in-lbs. This scoop
also wants to be on the instruction
plate.

~ lav- ~rr,,~~ -~I


There's some good scoop for you Nike-Hercules guys in TB 9-1400-299-
10/1 (Feb 66).
F'rinstance take a look at page 2-12-case Y075-19-C2-R1 (1-R). This
section of the TB gives you the word on welding both sides of the clamps that
you use to hold the cables in place when you march order the erecting beam.

Seems the welded end
of the clamps are breaking
away from the rest of the
clamp... and having both
sides of the thing welded THAT "
will be a big help. WELDED END
A little care will also go WILL
a long way, like when you BREAK!
go to take off the clamps.

HOLEY DIPSTICK








NOW, You say they have a

the hole plugged, or

LIKE THIS

STAKE A LOOK

Those quick-disconnect cable connec-
tors for your Nike-Hercules launcher
... do you take a close look at 'em now
and again? That goes for both the jacks
and plugs.
It's a good idea. You might spot
moisture, corrosion or bent or loose
pins -things that could cause all sorts
of trouble with the launcher or missile.
And be sure to get rid of any bugs
that might've got hung up when the
connectors were removed for a spell.
Bugs? Right... they can hold moisture.

OPEN LETTER


NOT THE DATE

Dear Half-Mast,
Pages 10 and 11 of TB 9-1400-299-10/1 (Aug 65) talk
about outdated roll charts for the Hickok tube tester,
model KS 15750-12, that we use at our Nike-Hercules site.
The TB says the number at the beginning of the chart,
3200, is supposed to be followed by the current year. In
other words, it's saying that for 1967 the number should
read 3200-67.
But our outfit and others that I know of get back the
same number, 3200-54, after we send the tube tester
out for calibration.
CWO N. W.
Dear Mr. N. W.,
You'll always find that
3200-54 number on the chart.
The chart calls it a code num- Model KS-15750-lar
ber .. and that goes for all 6 Code No.3200-5
digits.
Current year shows up on
the right side of the chart.

You say you haven't heard the word?
When you do... fight the temptation to go to your Nike-Hercules launcher
control indicator with a fistful of tape or safety wire.
Some outfits have taped or wired fast
SDON'T TAPE OR 3 switches that're not used-test load,
WIRE SWITCHES battery charge and external-internal.
-.. Seems there's a rumor that if the
S switches are put on accidentally, a BA-
472 battery might be activated.
Not so.
a _(Q On the other hand ... taped or wired
., switches could put an inspector in a
bad mood.

SPLASH GUARD SAVER
Talk about unfair wear and tear of
Nike-Hercules equipment.
The front splash guards on more'n
one M529 ready-round transporter
have been ripped to shreds by getting
caught in the wheels. And there's no
reason for it to happen.
That's right... MWO 9-2330-255-
30/5 (5 Dec 62) gave the word on re-
locating the splash guards and putting
metal strips on them.
No MWO kit was involved strict-
ly a deal in which your support people
latch on to the few needed parts through a
supply or locally. -

So you've got a new 4-wheeled Clark 290M Tractor-
all 54.000 shiny pounds of her. Pride is the word.


This tractor has what it takes. Dig our the

PRE-OPERATIOjL CH

LUBE FITTINGS-Some may have been left off, and every last one is necessary.
Besides, a check-over with the LO and TM in your hand is a fine way to find
out how this tractor is put together. Be sure you feel into the hard-to-reach
spots. Some fittings you can't see, but you can touch 'em, like the one on the
bottom of the universal coupler.
If any fittings have been left off, be sure they're in and used before you
make a move to get power up and work done. /

f


S HYDRAULIC RESERVOIR-Fluid, 125
gallons of it, should have been ship-
ped in the tank. Make sure there's
no water in the bottom, like by
having support take samples. If
you're where you can watch, be
around to see that dipstick test to
tell if the tank's full.

11 BRAKE FLUID-There are 4 reser-
voirs, and all have to be up to snuff.
Just cupping fluid to the bottom of
the inlet is right-no use running
over and dripping. Look at items
26 and 30, LO 5-2420-206-15-2,
and pages 37 and 38 of TM 5-
2420-206-15, for all-season lube
and hydraulic oil dope. If you have
to use the Interim TM, you can still
look the points and lubes up by
name.

coolant.
L TIRES- Take 45
PSI, but for long
trips on hard-top
roads, make it 50
PSI. For work in
deep sand, 30 PSI
is best, but change
back for highway
runs.

-Both have to be
off before you move
a peg. But no chuck-
ing them away, be-
cause they are per-
manent equipment.

1 CYLINDER CONNECTING
RODS-Heavy grease
has to be all off. Eyeball
the lift, steering, and
tilt cylinder connecting
rods. Clean hydraulic
oil, just a touch on the
plungers, you'll use to
coat the rods.







RED-PENCIL STUFF

That's correct. Every 8 hours your 290M is on the job,
you give these items a hard-nosed inspection, in addition
to your daily PM service.

UP FRONT-Pitch
strut, tilt cylinder and
lift cylinders, push
S'beams, and those cylin-
der rods get a lube
check, and oftener under
adverse conditions.
Then take a close gaze -
at engine oil supply.

MIDSECTION-Hydrau-
lic oil tank supply you'll
want on the mark. Then
those pivot hinge pins
S -take a make-sure by
S themselves. Steering
cylinders come next to
see if plenty OE 10 is
inside, and if the 4 i ..
fittings got their doses '
of MIL-G-10924B. .

REAR END-Cradle pins in both
places get lubed whether or not
they look dry. Else those hefty-
looking cap bolts on the end will
probably shear. There's no bigger

draulics. Next check and lube the

CHECK YOUR

T'H ENGINE WARMED barrels south of Bung Bung that the
UP AND IN transmission fluid, or converter juice,
NEUTR got full inspection, take nobody's word.
There are two places to look, and the
/ TM's LO and TM show 'em as No. 24
on the chart. But to do it, you have to be
running, and what's more, you got to
be up to operating temperature.
So take the TM method and warm up
until water shows about 180F. Then
check transmission fluid hot, with en-
gine idling, in Neutral.
But while she warms up, which a couple minutes will do, sit there in the
saddle before the chute opens. Check the controls, see that they're free and
working right. And if you don't have to get afield pronto, you can use colored
paint or tape to make your own red-line indicators for gages to mark danger
places by the TM.

NO SIMPLE JOB
Doing the wrong thing with this rig can be just -,
plain dangerous. The main things you've got to be careful about are:
STEERING--This is a full-hydraulic system, and 5 gallons, give or take a few
spoonfuls, go from cylinder to cylinder in a turn. That is, the power-driven
pump shoves those gallons in a few seconds-and if there's no shove, there's
no steering.
Your car back home had a manual override on steering. With engine off, you
could still turn to the side of the road and park. But Samson himself couldn't
wrestle this front end around with the engine dead.

OVERSPEEDING-In W R
plain English, that \ 'I
means running the en- 5s '
gine too fast. You're in ( RKP
danger when you hit WWU
2400 RPM, you're on
the brink if you go to -'
2700 RPM, and miracles RPM _
seldom happen to save s
you if you touch Rl-C, .I, l
3000 RPM. N


The thing is, those 380 horses up front gather in 20 extra horses at the peak,
and what's called a full-torque transmission is the harness between that herd
of horses and the load--and more horses means more speed.
There's been a new set of extra-strong valve springs put in the 290M since it
first came out, with tension upped from 85 lbs to 145 lbs. That's to help pull
the valves back from being hammered to shreds by the piston heads.
But here's the catch--it's not vehicle speed that counts. You can be doing
15 MPH, and still overspeed. The main danger is-

BRAKE &ACK ) DOWNSHIFTING-And using too low
POEFRE a gear. If you're running with high
P. E-A- S- E. '' RPM, and don't brake back before you
S downshift to tackle a hill, those 20
Setra wild horses and all 380 of the
branded herd are going to kick up those
S"." RPM's still higher.


Lose power, and you've got 27 tons of tractor,
plus whatever tons of 18-yard scraper and dirt
on behind, that you can't herd. Your only prayer
is that there'll be air enough in the 4 reservoirs
to stop you before you meet a mountain.

BUT THE BIG REASON
FOR LOSING POWER ON
YOUR 290M Is SPEED! L

This means one thing, which you'll watch like a hawk
-Never, but not ever, will you downshift for braking
effect. Instead of getting braking from the powerplant,
you'll get engine speedup from the shove of your vehicle's
weight. Your governor won't save you-all it does is
chop the throttle at the top end.
Even if you're not feeding fuel from the accelerator,
or as some throttle-jockeys say, "off-gassing," you can
get overspeed in a split second.

I'M PE-OIL- FREE-WHEELING-Kicking the clutch out, or going to
PRATEP' neutral can be bad in 'most any heavy equipment if it's
V- followed by going back into gear at good speed, because
S it's such a strain on shafts and gears. It's double poison
on this 290M. True, there's no clutch pedal here, but-
Even if you brake down to go back into gear from
neutral on this rig, that torque converter doesn't neces-
sarily match the drive-shaft speed. Hitting the accel-
S erator a fraction of a second early, before the engine RPM
and vehicle speed settles back, just invites red-lining.
Besides, the oil pressure drops when the engine idles. That little red light in
the middle of the left dashboard panel comes on when less than 20-PSI pressure
hits, and you can get oil starvation fast when you rev up.


WEE







But let's say you get away with high RPM, brake back, and don't blow the
top off the engine. There's still another piece of damage that can come from
using the wrong gear. That one's big, too.

OVERHEATING -That torque converter can boil fast if you use too high a gear
or lug along. About 200 or a shade over is normal, but if that hand starts reach-
ing for 250, watch out!
The thing to do
/ is brake back, if you

next lower gear
S- never two gears
.S V % at a jump.


Then check the temperature again, along with a quick
look at the transmission oil pressure gage.
If it's not at least 180 PSI, stop and shut off the engine,
with a 3-minute idle period first-don't just chop the
switch.


Still, your main worry here is what's
called torque converter stall. You can
even get it standing' still, using too high
a gear to move out. It's bad because it
overheats the oil, which means ruined
seals and shot bearings.







A'^ Q BAR BESIPES THE POWER-BRAKE
r \ ~.. IOMPLEx AND SUCH RANGERS -
HERE ARE SOME OTHER WATCH-
,\ OUT-FOR ITEMS.

TURBOCHARGER--It's a 4-star per-
former, all right, because- brace your-
self -it revs up to spaceman speeds,
5- 55,000 RPM-and any little abuse can
mean metal confetti.
The main way to keep the air-cram-
mer from shredding is, to never goose
the engine when you first start up, but
let it idle easy, not over 1000 RPM.
You let that go on for 3 to 5 minutes,
letting the bearings get oil.
HO GOOSING, PLEASE
And when you quit for the day, you let the works idle down. You'll know
never to kick up the RPM's and cut the switch, because oil is fed to that turbo-
charger system from main engine pump supply, and it takes as long as 6 minutes
for the supercharger blades to quit turning. Nothing that turns at such reach-
for-the-moon speeds can stand 6 minutes with no oil pressure.


BELTS--Air Compressor and water-
pump V-drives have to stay tight.
Otherwise you lose generator charge '
and the compressor shaft wobbles into
an oil leak and breakdown. Check com-
pressor bolts close.

FUEL LINE --All support brackets have
to be in tight, or the line will for sure
break at the head. Check every day.

SAFETY FIX

That cable northbound out of the tachometer drive is vital. It hooks up to the
overspeed governor on that bracket over the intake manifold. Keep it water-
proof tight, else it'll rust inside. This dope's not in your TM 5-2420-206-15, but
it's in the manufacturer's TM supplement in your overpack kit.

SPECIAL CAUTIONS






UNIVERSAL COUPLING-This big $900
ball joint on the back can get you into
all kinds of predicaments.
First off, take a glimpse at the tapped
block, adjustment screw and coupling
adjustment of the universal coupling. -
They're meant to hold the coupler from banging around. Draping wire rope
or cable on 'em could mess up the scraper eyes, so proper checks and maintenance
is the answer.
There'll be an even better lock for this coupler in the works soon, but for now
the word is a sharp eye and regular attention.

Z DIFFERENTIAL BREATHER-That breather
gets plugged, dirt and guck seal the air
I hole, and pressure inside forces GO 90
o 2 oil onto your brake drums. The preven-
S 3 tive is, check that breather every day
8 at the same hour, and oftener if the
7 6 going is dirty. That baby is one of the
worst problems you'll have.

But the cure for oil on the brakes can be only having your support replace
the brake shoes, all 10 of 'em. It's a multi-shoe style brake, and all the blocks
hate to be equally new or equally) worn. \ I i


HOOD REMOVAL-Tip )our support

can make it lots easier to get that hood
off and on. Then a socket wrench can
get the bolt eass, instead of ks turn at
a timune.


AIR-HYDRAULIC LINES AND COUPLINGS-
They go over like the cables of a sus-
pension bridge behind you to that coup-
ler assembly, but they can get cut by
rocks and snapped in turns. If you get
a break, the only thing to do is head for
the shop, slow'n' easy, because you can't
control that scraper without 'em. Be-
sides, you'll lose fluid and pressure, or
both.

Want to stop green corrosion in bat-

FSN 6230-542-6680, or similar?
You can line the cases with the plas-

When they're fouled up, replace with
something like Bag, Plastic, Polyethyl-

C8105/15-IL-A (Jan 67). But keep 'em
pasted back for plenty ventilation, and
change for clean ones every now'n'then.
Liners cut from sheet plastic like FSN
9330-756-2151 from Fed Cat C9300-
IL-A (Apr67) will do the same job.

A PIECE
OF
cuNNAGE
TO PROTECT




Earthmover blades-like on graders, scrapers and dozers-can be ruined by
dropping. Even with power off, a yank on the wrong lever can do the damage.
Blocking up in parking will stop such wrecks. Just let the blade down easy if
you're in a paved parking lot. On unpaved ground, use timber or flat-faced rock
to support the blade. This also helps to make the outfit stay put if it's not on
level ground."

LET THAT POUTY PET SET
*- -9.T I-


If it's a full-tracked tractor and she's conked on you, let nobody try to tow
your mad machine ... at least no further than up the ramp to the draggin' wagon.
This breed of cat has a bad habit of burning out transmissions if towed with-
out the engine running-same as a good many tanks.
What happens is, the oil pump won't go without the engine to horse it-and
the transmission turns over whether there's oil in the bearings or not if you tow
the beast. So no tow, no push.

PLUG CAN BE A DRUG
Your D7E tractor can get drowsy from poor crankcase ventilation if the
plastic shipping plug isn't taken out of the engine breather.
Those plugs are put in at the factory, for sealing purposes. If the D7E is run
with the breather blocked, the air circulation to the crankcase will be cut off
and pressure will build up and make oil gush past the rings-which means
caking and excess oil burning. To take the plug out, reach up inside the
breather pipe where it ends near the bottom of the engine block.

A leak in the manifold is a down payment on disaster because the terrific

TANK STARTER INSURANCE

If you have an M60, M60A1 or M48A3 tank, a CEV M728 or an AVBL launch-
er, your starter is a rugged piece of equipment, but it needs your help.


... AND THIS
O COULP HAPPEN
A AND VIDZI
O00D .

NI6HT










Tap the starter button too gently like you were trying to send a message on
a telegraph and your starter relay chatters and gives off sparks that can weld the
relay to the contacts. When this happens you have a closed circuit that you can't
open and the starter motor overheats and spins itself to death.
On 'tuther hand, you can get the same result by being too rough. Holding
down on the starter for over 15 seconds at a time will overheat the starter. So,
if your engine hasn't kicked in by 15 seconds, let your starter cool down for 3
minutes before you try again.
HERE'S THE RIGHT WAY
The right way to use the starter is with a firm, steady pressure like you were
ringing a door bell for not over 15 seconds.
Another thing you can do to insure your starter is keep your batteries up to
full charge. Well-charged batteries help prevent relay chatter.
A new, positive, ON-OFF contact starter switch, FSN 2920-930-6203, (P/N
11599638) coming into the system by MWO action should give you more
starter insurance.
The MWO will cover the M60, M60A1 and M48A3 tanks,CEV M728 and
the AVBL launcher.
Until you have the new switch installed in your vehicle, you'll need a firm,
steady thumb and fully-charged batteries.

But you don't change the markings on your older trailers except as spelled
out in para 4a in TB 746-93-1, that is, when the trailer needs repainting or the
old markings are in such bad shape they need replacing.

Use only new engine oil to clean and lube winch and

Whether these simple improvements are applied to your equipment is up to

When you're replacing light switch, FSN 5930-307-8856, on tactical and
combat vehicles, be sure to tighten the cable plug nut.
A final, good twist by hand ought to be enough to keep it from vibrating
loose and causing arcing between the plug and switch contacts.
The spanner wrench in the Automotive Mechanic's Tool Kit also works on
the plug, but you have to be careful behind the dash with it, what with all the
wiring for the different switches.
It also pays to remove the battery ground cable.

AIR MOBILITY HUEY (UH-1) HARNESS WON'T LOCK?

TRY THIS FOR SIZE!

A jammed inertia reel can ruin your whole day -and give pilots a real head-
ache to boot!!
So, if your favorite throttle jockey says the reel won't lock the shoulder harness
in either the manual or auto position, don't throw the whole kit-and-kabosh
away! Could be that a simple operation will put it back in condition.
Inside the inertia reel housing is a roller drum that the webbing coils around.
A webbing shield-either plastic or aluminum-keeps the webbing on the
drum and out of the locking mechanism.
Reels, P/N 0106176-0, with serial numbers between 32,000 and 45,000, have
a plastic webbing shield. This shield sometimes gets a wee bit out of shape. It
can slide off the drum into the locking dog-jamming the reel for real so the
harness won't lock.

SHIELD
JAMMED?





Al PULL IT
OUTI
When this happens, use a gizmo, gadget, or whatchamacallit to reach behind
the shield and pull it back out of the locking dog area. If the shield comes loose
don't fret-just push it back into position.
A No. 11 crochet hook makes an ideal tool for this job. You might even try
a knitting needle--knit one, purl two-knit one, purl two ....
Reels with aluminum shields don't have this trouble.

'ur M! CIGAI?


Dear Editor,
Comes the time when the Huey (UH-1) ground-handling wheels leak hydraulic
fluid and you can't get pressure up, here's a nifty little tool to have on hand.
We found that the leak was caused by a loose gland nut so we made up this tool
to solve the problem.
To use the tool you just insert the two prongs into the nut and make with the muscle.
The packing then become compressed to form a tight seal against the pumphandle
shaft, stopping the leak works like a charm.

(Ed Note-Good show! Sure beats using a hammer and chisel to tighten the
nuts ruins 'em every time.)

















Removing the magnetic chip detector insert plug at the Huey (UH-1) 42' gear
box is a hands-only job-not one for pliers!
Sure, it's a little hard to do-it was designed that way. But when you're
pulling an Intermediate inspection on the plug you don't want to ground the
bird because of broken lock pins on the plug.
So, when you lift the rubber cover to the plug, unhook the electrical wiring.
With your fingers, try to push in the plug as far as it'll go.
Next, turn it counter-clockwise slowly to release the pins from the plug holder.
If you push harder it's no-go. PUSH IT IN... 0K... NOW, TURN--
E-A-S-Y S-L-O-W









Hold it! Don't grab a pair of duckbill pliers-or any kind for that matter
-to turn the plug. You'll break the pins for sure and have some explaining
to do.
If you're the butterfinger type, call your friend Grunt the Gripper to remove
the plug by hand. Just don't use the pliers, p-u-l-e-z-e!

A Chinook (CH-47) went down in hostile
territory recently and had to be retrieved
because the forward transmission oil filter let go.
It seems somebody put so much muscle on
the filter retaining nuts that the mounting studs

'Course the only way to tighten those nuts is with
a torque wrench.Without one you never know how
much muscle you're using.

OTTER THINGS.. JAK' THE BOUNG TEST




Dear Windy,
Is there another way to check for low pressure in our Otter (U-IA) tail wheel shock

Dear Specialist W. P. W.,
You can make a visual check without servicing NO BOTT
the strut as called for in para 1-93 of TM 55-1510-
205-20 (7 Jul 65).
Put a lifting bar thru the lifting tube in the rear
fuselage. With a man on each end of the bar, bounce
the wheel vigorously. If the strut doesn't bottom,
it's OK.

SNot so, wrench pullers. In order for the pivot
arm to move the slide pointer to the exact timing
position of 25" before top dead center, the hook
end has to be DOWN.

Hey, common budd) -tpe!
While you're living that sheltered life atop the bed of a vehicle that's parked
for a time to serve as a communications castle, remember the truck can get joint
abuse from lack of use.
Take, f'rinstance, the AN/MRC-54(V) radio repeater set, AN/MRC-69(V)
radio terminal set or AN/GRC-26() radio set on the bed of a 22-ton truck or
the AN/GRC-46() radio teletypewriter set nestled in back of a %-ton.
The truck needs preventive maintenance, too. You say you know it, but you
can't move the truck because of the antenna cables, wires grounding rod fixes
and need for continued equipment operation.
Don't sweat it 1






Jack up the truck, put blocks under the axles to allow free turning of the
wheels, start it up and get the drive train moving.
You can exercise your vehicle during the weekly PM period on the electronics
equipment.
'Cause parking in one place a long time will allow rust and corrosion to creep
in as well as stiffening of the joints and bearings. The brakes will rust and freeze.
And remember, when you're blocking up the vehicle make sure that it's stable
and as level as possible.
TB ORD 1045 (Sep 62), Administrative Storage of Army Vehicles, fills you
in with good stuff for a vehicle that stays put for a period of time.

No need to repeat your DA Form 17 order for the same pub to the AG Publi-
cations Centers unless you get the word from them (on your Shipping Document,
AGAZ Form 944) that they cannot identify (Cl) the pub you want. They keep
your order on file and will ship it to you when they get it. It's listed on your :'
Shipping Document as DO for Due Out.
When you repeat your order for an item that was listed as CI, be sure to quote 'l
your source so that the Center can check it out. If you got it from the AG Bulletin,
then add in parenthesis after your listing, the Bulletin Number and the date of it.
Be sure to keep a carbon copy of the DA Form 17 you sent to the Center,
because they refer to the number on your requisition (6 a). For instance, you
asked for TM 9-2330-234-24P (Item 32) and C5, TM 10-3930-201-10 (Item 55)
and your Shipping Document was marked CI for those two items. When you
re-order, list the TM 9-2330-234-24P and C5, TM 10-3930-201-10 in their
,regular order on the 17. But after the TM 9-2330-234-24P (C4, 310-4), and
after C5, TM 10-3930-201-10.(Bul No. 1, 2 Jan 67). That info in parenthesis
will help the AG people identify the pubs.
If you're overseas, send your request airmail.

EIR & MD TB'S
You've seen those abbreviations many times so, you know they stand for
Equipment Improvement Report and Maintenance Digest Technical Bulletins.
But did you know those TB's are now good for 1 year from date of issue?
That's not all-they have a new numbering system.


The new numbering system gives you a clue as
to which command is responsible for the TB. The
numbering goes like this:


90 U.S. Army Strategic Communications Command 95 U.S. Army Weapons Command
91 U.S. Army Electronics Command 97 U.S. Army Mobility Equipment Command
92 U.S. Army Missile Command 98 U.S. Army Tank-Automotive Command
94 U.S. Army Munitions Command 99 U.S. Army Aviation Materiel Command

SOMETHING NEW ADDED

You'll find that some of those TB's have new added features such as a listing
of the current MWO's, as well as the forthcoming ones. There's also a new
section called "Simple Changes to Equipment".

Hurry! Ask for DA Circular 725-11
(8 May 67) Removal of Components from
Assemblages and Sets of Equipment. It
replaces DA Circular 725-5 (30 Jun 64)
as extended by TWX 11-409 AMSSM-
ST-A (19 Nov 66). You'll need it for re-
questing, recording and reporting gen-
erators, compressors, pumps, chargers
and other major components which will
be known as "used with, but not part
of" your sets.

Updated Recods duletd
Records up to date on all your equip-
ment? Check it out in revised TM 38-750
(15 May 67)-effective 1 July 1967. It's
a major re-write of rules on operational,
maintenance and historical records-in-
cluding those for ammo and for calibra-
tion actions. Two forms are combined,
4 are dropped, 1 (for aircraft) added,
others are re-designed. Implementation
instructions are in DA Cir 750-20
(5 Jun 67).

Getting it Up
You say you've been looking for a
teeny-weeny incandescent lamp (bulb)
for that emergency marker light set,
covered by SC 6230-93-CL-EO6 (Jun
66)? Sweat no more. FSN 6240-155-
8681 will get a couple of 'em. You'll find
the stock number in FED CAT C6200-
IL-A, Vol 2 (Jan 66), on Page 4.326.

gone? World-wide TT-ATAC message
4-11839 (26 Apr 67) says such re-wheel-
ing on all tactical vehicles up thru 10-ton
is not necessary unless the wheel is bent
so it's unsafe, or the inner steel core is
cracked, broken, or corroded with rust.
