YOUR HYDRA-MATIC


LUBE'S AN


Yup. it sure can tell sou a lot. For
example, next time sou dip sour stick
into that 21 -ton Hydra-Macic trans-
mission to check the lube level and a
"Eau de Hen-House" perfume odor
slaps you across the nostrils, beware.
brother. beware.
In case you neser whiffed this kind
of agricultural smell, burnt cork mixed
with oil is what to sniff for. There are
clutch discs and bands in your trans-
mission which are lined with cork-


a barnyard smell usually means that
these discs or bands are burning.
There's another way to check this
condition. Take a long look at the flid
iself-it should be clear. If it's a dirrm-
looking dark brown, you've got a case.
If one or both of these conditions are
fizzling .our truck, deadline the baby
and have Ordnance give it a medical.
Repairs that'll normally cost $4 or $5
can multiply into hundreds if the con-
A*tmnn -.anrminii"


While on this subject of checking
your Hydra-Maic fluid level,LO9-8024
(14 June 55) lays down new rules on
how ro do it. LO9-819A, which was
the word before LO 9-8024 hit the field.
said to check this transmission while it's
in neutral. No dice-the transmission
has to be in F-I High Range with the
handbrake set tight. Also, forger about
what PS 39, page 26 said about checking
the oil level. Some rpe got mixed up.
Seems that you'll get a reading that's
higher than the actual leIel of the trans-


.Mc




mission fluid with the transmission lever
set in N (neutral position) as your en-
gine idles during the level check. The
front drum that houses the clutch has a
nastr habit of throwing oil up against
the dipstick.
That LO9-8024 hasa lot of good dope
in it-dope that you'll need to keep )our
Hydra-Maric truck in tip-cop shape.
Check to see if you're got sour copy. If
not, ask for it and cite the "need-to-
know basis" paragraph in AR 310-90.
You can also see this dope in TM 9-8024
(Oct 55)






















In the old da.s, all an Arm) needed to get here it was going and back was a
horse mounted on four Li-shaped metal whanzits called "horse shoes." Today.
horse shoe, are something .ou throw at ro pegs sticking out of the ground.
Since the Arms truck has replaced the horse, and tires have replaced the horse
shoe, a lot of guys take that rubber on their heels for granted. The real facts
are-.ou can take it for granted if )ou gIe them a little understanding. They're
the best made but with a"treat 'em rough the can take it" attitude the 're bound
to bust a gut. Just gie them their due and they'll keep [our vehiclee floating on
air.
A tire is made up of the tread, breaker. cushion, plies of cord and bead wires.
Each has its own job to do.




Most of sour tire parts-the breakers, the cords and the cushion-are built to
take up road shock If an) of these parts bust a gut. that road shock is going to
knock that tire right to tire heaven. Here's a h -a tire weighing about 20 pounds
carries a load nearly. 50 times its own weight. \ hen this tire travels about
45.-MPH.a forceof abour a ton is built up trying to tear it apart. That tire has
got to be on the beam to take that kind of treatment.
The best rule to follow is:if one of sour tires looks suspicious, take it off and
get a new one.You don't have to be ashamed of handing in a tire that has a small
cut into the cords. Small cuts get bigger and deeper and soon it ma. be too late
to sale that tire. Cuts in the rubber onl. are not so serious.
Another rule-as soon as the tread design disappears in the center of the tire, or
at most about 3' of the wa% across the tread, get a new one. If .ou wear the tread
too much, the ttre can't be recapped. It has to be iunked. Then again a smooth
tire picks up a lot of nails, sharp stones, etc.










Certain things and conditions will turn a tire into nothing more than a flapper.
These things and conditions are your tire's public enemies. It looks to you to bar-
ness these idjits. Here they are-

)NE TOO MANY


Dtai Hall- %Iail.
II't're having qmite a time getting
amntetr p s loi our .11-seie ehiclei. The
meter it c' e been getting has one con-
necto r oIn ci while the illltks are
equipped to take te re connectors-can't
make a round peg fit a square hole.
Could it be' ll at irt' e missed an
,1111 0 telling tus to require theei ont-
cotilector a mmeteri -o they'll fit out
lu o-connector trucks .
SP.j G. .1. 11 .

Dear Specialist G. NI. V..
Better tell .ou right quick that
those one-connector gadgets you'ree
talking about are not ammeters-thc 're
solimeters.
All sour new MN-seres vehicles are
coming through aith solimcters IOrd
Stock Nos. G'-12i83"'6 or G'i9-
"3542321 instead of ammeters. The
earl. -production m hicles hase the ammeter (Ord Stock No.
G"'2-"288i4) the rao-connector
jobs.
When .ou send in a requisition for
new meters, the thing )ou'll hase to do
is specify aherher iour trucks take the


%olcmeter or the ammeter. This is the
onl[\ 'ar you'll be sure chat )ou'll get
the right meter for )our truck.


- GREEN


Eventually all trucks %will ind up
itrh the ,olimecer. This will happen
when the Arms supply of ammeters is
used up. E[en no there's an M\\ O in
the mill which wilI tell ou how tomake
the change-o'er from ammeter to solt-
meter. This MN\\O v on't take effect,
tho, until the ammeter suppl. is ex-
hausted.
The apparent reason for the change is
that a voltmeter is easier to read and
understand. A soltmeter measures volt-
age -natch. There are three colors on







this meter red, .amber and green.
When that needle's on red it means your
electrical system isn't producing enough
juice-usually when your voltage.drops
-below 24 volts. When-she's on amber,.it
means your system is turning out any-
where from 24 to 27.5 volts. You'll usu-
ally get this reading when your truck's
idling. Green, of course, means your
system's cooking with gas- she's pro-
ducing at least 27.5 volts.





ON THE WARPATH


Dear Half-Mast,
It's gotta stop, 'cause if I find anyone
messing around my trucks, I'll cook
him alive.
Now that I've blown off some steam,
I'lltell you what this is all about. Those
service tail and stop light assemblies are
at fault. They're listed in all Ord 9's for
the -M-series tactical wheeled vehicles
but not-in the Ord 7's. Which all means
that the-using units can't get them-with-
out going through a lot of red, green
and purple tapes.
And, because of this, there's been a
lot of underhanded dealings going on
around here. All I know is that the other


day I went around looking at a couple
of M34 2/2-ton trucks and those blank-
ety-blank .lights were missing. In other
words, Sarge, it looks like a lot of guys
around here are becoming a bunch of
cannibals.
Tell me what to do, Sarge, before I
go beserk altogether. My nerves are just
about shot and unless I find out how to
get those lights fastest someone's going
to spend a couple of weeks in a hospital.
SFC B. S.

Dear SFC B. S.,
Hold it now, boy. For your nerves I
suggest you take a bromo, and .then
when you've calmed down, listen to
what I have to tell you.
First.off, the Army's recognized this
problem .and has come up with an ex-
cellent fix from now on those lights
will be in all the Ord 7's.
As you know, all your trucks except
the G741 3-ton series use the H004-
7760506 and the H004-7760507 assem-
blies. The H004-7760506 is the right-
hand light and the other goes on the left.
The G741 %-ton trucks use the
G741-8328083 assembly for the left-
hand side and the G741-8328082 as-
Ssembly for the right side.
As each revision to the-Ord 7's comes
-out, you'll find these stock numbers
listed, which means you'll be able to
get these assemblies with no sweat at all.
Fire off a letter to me any time you
discover any other item that's fouled-up
- like these light assemblies.

STORING DRY-CHARGED
BATTERIES

Dear Hall-f ast.
Houn long can a dry-charged battery
be stored? And particularly, hou' long
can it be stored in the battery box of a
vehicle? II'hat about rain getting-on
stored batteries?
SFC G. D. 5.


Dear SFC G. D. S.,
For all practical purposes. a dry-
S charged battery can be stored indefinite-
ly. Some folks say "forever." but nobody
has lived that long to see.
But, the joker is that it must be kept
dr). Batteries in the banery boxes of
schicles will have a good chance of stay-
ing dry, inside the cells where it counts,
as long as the caps are tight. The caps
of the military batteries are designed to
keep w after out even if the barten is six
feet deep, so it isn't too likely that rain
on the tops will get in.
On the other hand, everything you
can do to be sure those batteries stay dry,
and out of the real hot sun. will help you
be sure they are ready when you need
em. Take a long look at TM 9-2857.
(15 Ma\ 45) for the word.

BRACE UP

Dear Half-Mast.
What can I do to keep those third
wheels on the .11104 trailers from sag-
ging on me.
Seems the slightest movement ol the
trailer breaks the bracket bracing the
u heel, which in turn causes the wheel
to mugu ump all over the place. II"hat's
your fix, Sarge?
Sgt T. 1. M.
BRACE

BRACKETS












Dear Sgt T. Y. M.,
Not my fix, Sarge-rhe Army's. Take
your trailers back to Ordnance and have
them put MWOOrd G'54-W4 (" Jan
55) into operation.
This'll fix 'our trailers up right well.
The MWO tells Ordnance to brace those

trouble again.
"Urgent" is the word printed atop
this publication. And you know what
that means-urgent.


v^~!""





















Your "5-ton truck can have one of
three types of carburetors on it--the
7375469, the 8327282 or the 8331877.
That last one-the 8331877-has what's
called a degasser built right into it.
.


This degasser stops your engine from
dieseling-that's when your engine
keeps running after you shut the
ignition off.
What happens is this-the heat in the
combustion chambers really builds up
when your truck's running. When you
turn off your ignition, believe it or not,
your truck may keep running, because
this heat ignites any fuel mixture still
in the chambers or flowing into the


chambers from the carburetor. To stop
this, you pull out the anti-dieseling con-
trol wire on your instrument panel.
Then, when the engine dies, you turn off
the ignition switch.
But those two other carburetors-the
7375469 and the 8327282-don't have
built-in degassers. This is where MWO
Ord G744-W23 (28 Sept 55) comes into
the picture. This MWO says you're to
take your truck back to Ordnance and
have them put a quick-opening valve
on your intake manifold to stop this die-
seling. It's marked urgent.


When you open the valve, you let a
free flow of fresh air into the intake
manifold which stops your engine from
dieseling. O'course, you have to be sure
you close that valve when you start your
engine again.

The hammer-and-tong method's no
good when the manifold hear-control

M38 Jeep. The first thing some people
do vhen the; run into this kind of
trouble is grab the counterweight vw ith
a wrench and twist it.
The best sta% to loosen up the shaft
is use a little penetrating oil mixed wirh
graphite on the bearing end of the shaft.
Let it stand for a while to soften up the
carbon. Then tap the end of the shaft
with a hammer or a block of wood. To
keep the shaft from freezing. give it
some oil and a tap at every C maintre-
nance service.
If the freeze is still on the shaft after
you do this, then you'll have to take the
intake manifold off, free the shaft and
oil it.









Next time you remove the spark

Give your .30 cal. M1917A1
Browning machine gun and your-
self a real break next time you've
got a few minutes to spare by com-
paring her with this chart. If any
of the parts are like it says here, fix
them up, (if you've got the spare
parts and have the tools) or get help
from Ordnance.
Even one little dent or crack
noticed in time prevents the gun
from being goofed up later with
maybe serious damage.
Look sharp for cracks every-
where. If the gun has fired a good
many rounds, double-check the sear
and firing pin notches. If they get
too rounded or worn, you've got a
runaway gun or one that'll fire
when it's bumped. The barrel ex-
tension and front projection of the
lock frame take a beating and will
break if timing is incorrect. They
usually crack before they break.
Look over the water can and con-
necting steam tubes for cracks and
loose fittings.
If the M1919A6 is your baby,
look inside the bipod head for dirt.
or grit. See that the bipod doesn't
bind with the front barrel-bearing.
Check inside the flash hider for
carbon.
Give your gun a good look-see,
because as you know, an ounce of
preventive maintenance is worth
two in the bush.

CHECKYOUR GUN






CHECK YOUR RAMMER

Hold everything until you've checked
the loader-rammer on your piece. If
you're using Rammer D031-7307416
and it's got external threads, junk it and
requisitiun a new unc.
old




The old style rammer D031-7307416
has an external thread which is easy to
damage. So you've got to requisition the
new designed rammer, which has an in-
ternal thread and a rubber cushion on
the face.

new

RUIBBLR
FACE

But here's the catch. The part num-
ber of the new rammer is also D031
7307416. So make sure supply has got
the new one, and then make sure you
specify on your requisition that the
rammer you want has an internal thread
and a rubber cushion on the face.
It's sorta like having two girl friends
with the same name at the same number
- one's a blonde, the other a red-head.
First, make sure the one you want is
there. Then when you ask for her, give
a complete description so you'll get what
you want.
In case that new rammer isn't avail-
able, use rammer D039-6108585 as a
substitute until you can get the right one.


YES- SUR

Dear Half-Mast,
What about the gas piston nut on the
MI carbine? Is the using unit supposed
to clean 'em, and if so, how come we
can't have the Ordnance tool for pulling
'em out? We have found the removing
tool, M5, to be inadequate.
Lt H. V. Z.
Dear Lt H. V. Z.,
Cleaning the gas piston nut on the
M1 carbine is one of those "Yes-But!"
propositions. Yes, the user cleans it-
but only under the supervision of the
organizational artificer, and only when
the carbine gets sluggish-failure to ex-
tract, for example. Cleaning this nut
every time the piece is fired would wear
it out entirely too soon. See FM 23-7,
pages 92 and 93, para 48 c for the
poop on this.


im


As for the M5 tool being inadequate,
if you find a weapon in such bad shape
that this tool won't easily remove the
cylinder nut, you'd better send it to
Ordnance for repair.

A PEEP WILL DO IT


Dear Half-Mast,
Will you give me the authority to
quote so I can either requisition bore-
sighting equipment for my 76-mm gun
on the M41A1 tank or else get Ordnance
to do the job?
It tells how to boresight right in TM
9-730 for the tank and gun, so I must
be supposed to do it. But my requisi-
tions for bore-sighting equipment keep
bouncing back, and they keep telling
me that the stuff is not authorized on
the organizational level. What do I do?
M Sgt F. S. K.


BEFORE YOU ATTEMPT BORESIGHTING, PLACE

Dear MSgt F. S. K.,
Breech and muzzle bore sights are no
longer 1st and 2nd echelon issue for
combat vehicle mounted, direct fire,
primary weapons up to and including
90mm gun (except the 40mm guns).
Take a look at TM 9-730, page 348,
para 272. It tells you how to bore-
sight by using the percussion mecha-
nism firing pin hole and bulk cord fas-
tened to tube muzzle for boresight lines.

Dear Sgt Dozer,
Our commercial type dumps and In-

tion trucks don't have towing pintles
on the rear end and aren't to. be used for
towing.
We have had cases, however, of some
meathead dropping a chain or cable
over the rear cross-member of the frame
and trying to tow with it.
The result? Bent frames, because
they're just not designed for towing.
To keep this from happening, we
made up a 1-in stencil and painted NO


TOWING
TOWING on the cross member. Since
doing that, we haven't had a bent frame.
MSgt R. M. H.

Dear MSgt R. M. H.,
Darn good idea-but only as a last
resort. Anybody who'd try to tow with
one of those vehicles evidently didn't get
the right kind of training or he'd know
better. Well-trained and competent op-
erators shouldn't need signs to tell 'em
what not to do.











NO GREASE HERE

A lot of fellers have the old-

fashioned idea that you ought

to grease the blade circle re- --

verse gear on those Engineer

motor graders. Whether you're

driving a Caterpillar, Warco,

Rome Adams or Austin-

Western grader, remember not

to grease this gear. Here's why:

The blade circle reverse gear AS

used to be greased, but the in- DE nBLA
IR [ REVERSi
dentions of those gear teethbe- EA

came handy resting places for

dirt and sand. This material

acted as an abrasive and caused extreme wear to the drive- pinion gear.

That's why the gear isn't greased nowadays, so keep this one in mind.

Good e CRANE OPERATION
Is a must in... RANE OPERATION
You'd be surprised how careful operation can add to a crane's life. It
makes no difference what kind of a rig you're running, the operator and signal
man are the guys who determine what kind of service your crane'll put out as
the hours pile up.
Yep, careful operation's got just as much to do with good preventive
maintenance as making adjustments, tightening nuts and bolts and doing the
before, during and after operation services.
When you use a crane, it's just like using a hand tool. You get the right
one for the right job. Your machine's got to be able to make the lift or do the
job you ask. And don't forget to make good use of your outriggers. Extend
'em for safety's sake if you're approaching the equipment's operating limits.
After you've selected the right crane, here are a few things you've got
to do before making a lift:

FIRST, CHECK TO SEE CHECK POSITIONING CRANE SHOULD
BE SURE THAT SLINGS OF RIGGING TO BE BE CLOSE
CRANE'S GOT AND FASTENINGS SURE LOAD'S ENOUGH TO
