When it comes to maintenance,
training gets mighty important.
If you've got anything to do with
using or maintaining Army equip-
ment (and who doesn't?), you've
had maintenance training from the
start. Like, when you were issued
your first equipment rifle, pack,
cartridge belt and shelter half. The
sergeant gave you the low-down on
how to keep them in top shape.
With the Army's equipment get-
ting more complicated, maintenance
gets more important for fighting out-
fits to keep combat-ready.
If you want to get on top of your
equipment maintenance and maybe
make a career of maintenance (lots
of guys do), the book you want to
give the eagle-eye is DA Pamphlet
20-21, "The Army School Catalog,"
dated August 1962, with dozens of
changes.


iu VA 1 Is 0 110


S-- .__ -


It lists Army school courses .
many of them in maintenance.
Wheeled and tracked vehicles, radios,
radar, missiles, artillery, engineer
equipment, aircraft. .you name it.
And what's more, there are courses
for officers as well as enlisted men.
There's a special preventive main-
tenance course at Fort Knox for field
grade officers within CONUS. Some
overseas commands, like USAEUR,
have their own PM courses. Also,
many divisions and posts have set up
PM courses based on DA Pamphlet
750-2, "Post Level Preventive Main-
tenance Course."
Now, the thing for you to do is talk
it over with your sergeant, training
officer or CO. Then your request
(DA Form 1049) will go in to at-
tend the maintenance course that'll
help you on the road to a mainte-
nance career.

BACK-UP SAFETY CLAMP


TN PIi


Dear Editor,
You just can't be too safe around a missile site-but you tan get gigged
easy for not being safe enough.
Here's how we clinched the safety deal when carrying M409 warhead sec-
tion containers with our 10,000-lb rough terrain truck. In addition to using two
load binders (FSN 3990-250-6356,1 to hold the M409 to the mast, we use two
"C Battery clamps"-a gadget dreamed up by a couple brains in the outfit.
Now everybody's happy-the inspectors and the M409, which rides easier.

So-you've got problems in your
Nike-Herc system right after installing
a chassis that's just been calibrated or
comparison checked!
That's not good, but don't get grabby
or too hasty with your accusations.
Give the newcomer a chance to prove


itself. Start your trouble shooting else-
where in the string. For example, tackle
the chassis ahead and behind the one
you've just put in. If they check out
OK, then you can point an accusing
finger at the newly-tested chassis.
Checking out the newly installed
chassis first, can easily add to your

problems (and increase support's work-
load). 'Cause if the chassis is OK to
begin with, you can easily throw it out
of adjustment as you try to run down
a problem .. which isn't there. Then
you have no choice. You'll have to send

the mistreated chassis back to support.
So make a note: When swapping
chassis, as always, you can't beat good
trouble shooting procedures.
Your payoff will be fast and efficient
maintenance ... and, you'll ease your
load, and everyone else's.


Sure you know!
On your Improved Nike-Hercules
Acq receiver-transmitter, 8515397,
you simply tie a jumper lead between
TB 5-5 and TB 5-7, when you pull the
frequency-and-power meter, 8173152,
for calibration. And, then you make
sure you remove the jumper wire be-
fore you replace the meter.
But, do you know this simple tie-up
is strictly taboo when you remove this
meter from the receiver-transmitter,

to use a plug to keep things orderly
while the meter's out for calibration.
Support'll get the plug (Connector,
electrical, FSN 5935-614-0534) for
you. But you have to ask for it on a
DA Form 2407 (Maintenance Request),
'cause before you use it support has to
wire the plug's L and D pins together.
Once the plug is wired, like so, all
you have to do is plug it in when you
remove the frequency-and-power meter
for its 90-day C check.

Any bird part that takes a belting deserves a lot of attention. The safety belt

no exception.
That's why restraining equipment on birds gets checked for damage, freedom
of adjustment, and locking and anchoring security during a Periodic. You want

Be sure you've got a shoulder harness installed in your aircraft. If not, check
out the Index, DA Pamphlet 310-4, for the MWO that puts the harness in your

UPU








One ground-handling wheel on your Sioux (OH-13) is like another-but
there's a mighty important difference in the axle.
A left axle will work on a right skid and vice-versa, but there's a little detail
that could prove to be a real trouble maker-the axle handle.
When you use a right axle on a right skid, the handle faces rearward-as it
should. But when you use a right axle on a left skid, the handle faces forward.
So what's the difference?
Well, suppose your chopper is about to be set down out in the boondocks.
That forward-facing handle could snag on brush and upset the applecart!
So, play it by the book. If your bird is sporting two left or two right axles,
make a beeline for the parts pub.
That's right-you requisition a right axle (FSN 1630-787-2527) for a right
skid and a left axle (FSN 1630-787-2528) for the left skid.






POWDERS TO EYE BY


Dear Windy, --
We've been running all over the place trying to buy replacement powders
for our magnetic particle Inspection machine. So far we haven't had any luck.
Is there a TM in the works that will replace the manufacturer's pub and give
us the scoop?
SP 5 A. E. W.
Dear Specialist A. E. W.,
The powders you're looking for are listed on Page 147 of Federal Supply
Catalog C6800-IL (1 Jul 64). FSN 6850-255-0451 will get you a 25-lb drum of
black powder. FSN 6850-255-0452 will get you the same amount of gray
powder and FSN 6850-255-0453 will get you the red powder.
The deal on a TM for this "off the shelf" item is a familiar one. In brief,
only a manufacturer's pub is needed to tell you how to operate and main-
tain the machine.

Mohawk (OV-1) could have something in common. The actions of a "heavy"
can really foul up the works.
Take the charged ejection seat. Planting yourself smack on the safety pin
streamer can put enough force on the connecting cable to bend the ejection gun
sear. And if that sear can't be pulled out the seat isn't going to fire.
So-o-o when you're in the cockpit, easy does it. No sitting, pulling,
yanking or stomping on the streamer-p-u-1-l-e-a-s-e!




















S There're places where you have to make like Houdini
on your Huey (UH-1)-that's for sure.
Take the tail boom attaching bolts. Getting a
wrench in there to check the four bolts for tightness
has been a problem ... but it needn't be any longer.









So, throw away your magic wand and make this
jim-dandy tool from scrap for the bolt nuts.
Before you make with a torque wrench on the end
of the tool, tho, be sure to check the maintenance pub
on use of the torque wrench with an extension attached.
For example, if you use the 5-in tool at right angles
to the torque wrench, you torque the nuts (not the bolts)
like so:
I UH-IA All Nus 200-220 inch-pounds
UH-IB Upper Right Nut 520-580 inch-pounds
(Facing oft)
SUH-1B Other Nuts 200-220 inch-pounds
SUH-1D Two Upper Nuts 730-790 inch-pounds
UH-10 Two Lower Nuts 240-270 inch-pounds
But if )-iu use the tool straight out as an ectension to
the torque wrench you have to "figure" the smaller
muscle power needed on the handle to get the torque,
sure 'nuff.

When your favorite throttle jockey heads his Kaven (OH-25) cross country,
one of the basic instruments he's betting his hide on is the magnetic compass
... and rightly so.
A faulty compass, therefore, could strand him "somewhere in the boon-
docks." And that's just about what'll happen if the RT-294 of your AN/ARC-
44 FM radio set has a Western main tuning gear drive motor.
The magnets in this motor are extra strong. Fact is, they're so strong that
the magnetic field build-up will throw the near-by compass off ten degrees or
more.




IF 01FITS A
WESTERN MOTOR
COMPASS NEEDS
RECALIBRATION
RT-294 OR SET SWITCH
IS IN ORDER

So, if the compass has been actin' up in your bird, buzz your avionics sup-
port. A look inside the set will quickly show if it has a Western motor. If it
has, either the compass needs recalibration, or a set switch is in order.
Some avionics shops are even stenciling the RT-294's with a Western like
so-NOT FOR USE IN OH-23. 'Tis a good way to head 'em off at the pass.

Putting the clamp to the guard of the antenna lead on %our AN/GRC-19 ClU
radio set can be a gripping experience.
Or it can break you all up. Rather. if .ou like, you can break your clamp
all up.
The guard just has to be snugged to give the antenna lead the protection it
needs. It kinda' gives it a good grip on things.
If you put the pressure to the clamp screws. the clamp's just as likely to/
break off next to the guard as not. If it doesn't break, chances are it will the
next time or two you overtighien the screws. l

TIMELY TIPS ON THE PRC-47

COT A

One dictionan definition of "cap.
tice" describes it as "checked from

That describes right well the captive
screws on the control panel cover of
the RT-6"I, AN/PRC-47 radio set. A
few turns of the screws release them
from the case of the radio set. The
screws then sta\ in and with the re-
leased cover. Which means they're
supposed to stay there, captive-like.
Some energetic types have been
known to rake the screws all the way
out of the cover. It mam be good exer-
cise, but it leads to lost screws.
Lost screws might not be so bad-
when iou can replace them. Those
coser screws fyou guessed it?) are
slightly odd-ball. Like. )ou can't requi-
sition new ones. You've gotta ask your
support to come up with replacements .

gets you up-ro-dare on parts.


-






















So you've been wading around with
your AN/PRC-6 portable radio set
during fording operations and
maybe the set got wet.
Never take chances. Better open 'er
up the first chance you get and take a
peek.
If she's damp, wipe the moisture
seal with a dry, lint-free cloth. And
use that rag like a powder puff on the
chassis by gently patting.
After drying the innards you'd bet-
ter drag the rag over the outside, too-
including the antenna.


If no cloth's handy, leave the set
open and let air dry it whenever
possible.
Before crossing that stream, swamp,
lake or boondocks mudhole, remember
to shut off the air valve. Just don't for-
get to open it before you operate.
It'd be a good idea to glance at the
case clamps to make sure they're tight.
This helps keep the dewdrops out.
With the AN/PRC-8 thru -10 series,
only the outside needs attention.
Dry with a rag-or let air do the job.

For an evening gown or other female-type teasers, the strap ess cover prom-
ises all kinds of delights.
For your BB-451 battery used with the AN/PRC-41, -47 radio sets, the
strapless cover promises all kinds of problems.
To elaborate: that nylon retaining strap on the battery serves a number of
purposes, like making sure the cover doesn't get lost ...or making positive it
goes back on only one way, and so forth.

NYLON STRAP
MUST NOT BE
MISSING











LUGS FIT HOLLOW BRACKET

Replacing the cover right is the one to think about here. F'rinstance, if the
nylon strap's missing, it's possible to position and snap the cover on wrong.
Like, those two big lugs can be forced down on the radio cable receptacles
and bust up the connecting pins.
That's bad enough, but that same situation also can short out the battery.
Ugh!
If the strap's gone from your cover, a quick look can tell you whether you're
positioning it right on the battery case. The lugs on the underside of the cover
fit into the hollowed metal bracket of the case. The cover side featuring the two
openings goes over the receptacle side of the case.

PINNING IT DOWN
Dear Half-Mast,
TM 11-5820-401-20 and PS Magazine have pretty well spelled out that you
got to be careful with the tube puller when you're removing the power am-
plifier (V6101) tube from the receiver-transmitters of the AN/VRC-12 series
radio sets.
Like, we're told not to rock or rotate the tube, etc., to keep from damaging
the pins. This is fine, but a lot of Joes don't seem to realize it's a two-way
proposition. Meaning, the tube pins still get damaged.
The reason: Unit mechanics are wiggling the tubes when they put 'em back
in! As you know, those pins bend mighty easy-and the tubes have to go in
as straight as they're supposed to come out. Otherwise, pffftt!
Maybe you can drop a reminder in PS.

V hen you're tracing or otherwise checking circuitry-

Like, don't mark those circuits wtih a pencil, man. Just
a [race of graphite creates another circuit... and a current
leak.






NOT HARDLY...


Not too hard, please, when you're usin' your mitt to get the grit from the
contact pins.
Some pins don't stand up to the strain and may leave you speechless.
Good examples are audio connectors on AN/GRC-3 series radio set com-
ponents.
Too much push, like with a pencil eraser or such, can anchor the pins down
just far enough so's they don't meet the contacts of the audio cable connector.
Result: speechlessness.
Just a little pressure'll clean the contacts. Not hardly ....

Front Fender Guards-The old type fender
guards break real easy if you try to straighten
out a dent in 'em with a hammer or a tanker's
bar. However, if they're rubbing on the track
you'll have to do some pounding-but be gentle
as possible. The vehicles produced after data
plate serial number 1516 have a different con-
tour which should prevent this trouble.

Towing-If you have to.tow your Ml14 (other than in tow starting) have your
company mechanic take out the sprocket axle shafts, then you can tow it with
no danger of damaging the power train. If you leave the axle shafts connected
you can ruin the geared steer unit.
One thing about towing with the axle shafts out: The towed vehicle has no
steer and no brakes, so you have to tow it with a tow bar, not with tow cables.
So-o-o-o, IF YOU TOW, GO SLOW.


WHEN THE MECHANIC PUTS THE
AXLE SHAFT BACK, WE SHOULD GREASE
THE ENPS LIGHTLY WITH 3-AA.


Drain Plugs-There are two types. A threaded plug was used on the early
M114's (data plate serial number 165 and below except for vehicles 158-160
and 162-164) and a type with 4 screws (6 screws for the larger engine oil filter
drain) was used on all vehicles with serial numbers above 157 (except for vehi-
cles 161 and 165).


I ~ -- -~


r






For the threaded plugs you use a V2-in square drive wrench along with an
adapter-socket wrench 3-in square drive male to /2-in square drive female,
FSN 5120-240-8701, for removing or installing plugs. Also, lube the threads
lightly with GAA grease. These plugs are made of soft metal so be careful
of cross-threading.


Engine Compartment Access Cover-The front slope
plate must be watertight or you'll be in trouble when you
go swimming. Be sure the washers are in place under the
attaching screws.



Shipping Cover-Keep the shipping
cover that comes with your M114A1
and use it as the vehicle paulin. You
carry it in the right, rear, hull plate
extension. If you don't have one, order -
FSN 8340-256-4122.


Serial Number-The vehicle serial number is on the
data plate in the driver's compartment. This is the num-
ber you use on your Equipment Log Book (DA Form
2408 series) and other TAERS forms.

Headlight Guards-The headlight guards,
(10910014 and 10910015) sometimes get torn off
in heavy brush. These steel tubing and angle iron //
guards are not in the supply system so you have to
repair 'em by welding or by making complete new
ones locally.

New Fan Belts-The matched set of three V-belts listed as Item 20, page 27,
of your TM 9-2320-224-20P (Jul 62) has been improved. The new belts can
stand up longer under high tension. They'll be listed under FSN 3030-967-3344
and each individual belt will be marked (10922131) instead of (10920729).
You might want to jot this down in your parts manual.

MEDLEY FOR MECHANICS

Transmission Adjustment-When a new Ml14 is delivered to a unit it is
very important that the company mechanic check the transmission front band
adjustment. He must also keep a regular check on this adjustment. If he doesn't
the transmission can be ruined.
Change 2 (Aug 63) to TM 9-2320-224-20 (Jun 62) tells on page 18, para 96,
how to make the adjustment. Be sure and use Change 2 because it has the latest
dope.

Brake Adjustment-Change 2 (LAUNIT FILTER
(above), page 18, para 101.b., gives SEMI-ANNUALLY
the latest way to adjust the brakes. It's
a must for every mechanic's library.

Steer Unit Filter-The geared steer
unit external oil filter is hard to get to
because it's mounted under the voltage
regulator bracket. However, don't miss
it when you make the regular semi-
annual service. This filter traps a lot
of gook.


WINTER WONDERLAND
Oil Filter Foul-up-In cold weather (zero or below) your geared steer oil
filter takes a terrific pounding. In a couple cases the stiff oil hammered the filter
element away from the top of the filter.
To prevent this you ...

1. Use the right weight oil or 2. Never move the vehide until your engine is wnrmed'-
the prevailing temperature up completely. (At leaos 5 minutes in told weather.)
Sang like it says in the LO For the first three minutes of.th we never
S -. go above a fast.idle.




Winterization Kit-Wanna know if your vehicle rates a winterization kit?
The latest word is that a special winterization kit will be issued for the vehicle
only if long-time operation in -250F climate is planned. SB 9-16 is your author-
ity for winterization equipment.






Fast Idle-In starting your engine at temperatures between 0 and -25'F you
need a fast idle.


After you get your engine started, push your choke knob in slowly. You
don't need to touch the throttle knob until the engine is running by itself.

Slave Starts-The mstrer sn itih in )our M114 is wired in one of two differ-
ent ways. Because of this you need to know the various slaving methods. Re-
gardless of how it is wired, the first six steps are the same.
It's done like this ...

5. After the DEAD (slaved) vehicle engine starts, turn M ER
OFF the ignition switch in the LIVE vehicle. Slaved
vehide engine will run OK. II'lI draw juice from the
batteries in the LIVE vehicle. Do this because you
can't be sure two generators will operate in parallel
without causing trouble. F oF
IGNITION


6. Slaved IDEAD) vehicle let the engine worm up 5 to 10 minutes. Then turn its master
switch ON to connect its batteries.
II the slaved (DEAD) vehicle has late model master switch wiring, (serial number 1218 and
above plus 1204-1212) flipping its master switch to the ON will connect the batteries so
jump to Step 7.
If, on tetherr hand, the slaved (DEAD) vehicle has its master switch wired the early way
(serial numbers 1217 and below except serial numbers 1204-1212) you need another step in
here. Call it 6a.


6a. To close your master relay you must first flip ON the
master switch, then flash an electrical current through '
your master relay coil. JUMPER
To do this run a jumper (booster) cable from a good ABLE
battery's negative I-1 terminal to a negative terminal
of your DEAD vehicle batteries. Now attach a jumper cable M J*ER
to the positive (+) terminal of the good battery and .'
flick the end of this cable across a positive terminal of i
your slaved (DEAD) vehicle batteries. This'll close your
master relay.







7. Whether your last step was 6 or 6a, your master switch is now ON in the slaved (DEAD) vehide.
Jusi le the ~ series charge for a few minutes.






TO STOP YOUR ENGINE

A point to remember to stop your engine first turn OFF the ignition switch. After the engine has
stopped turning over, turn OFF the master switch.

The cold-weather repair kit for boots and mat-
tresses is so tiny you can carry it in your boot or bag.
It works like a tire patch and will take care of any
small puncture or tear. The instructions on the kit
are easy to follow, too.
The pressure-sensitive tape can be used for emer-
gency repair of raincoats, ponchos and wet weather
overalls; but this is only a temporary repair and the
item should be turned in for permanent repair as
soon as possible.
When patching a raincoat, poncho or overalls, use
the liquid adhesive cement with coated nylon cloth
or a piece snitched off an unserviceable garment.
HERE'S HOW:

T14AT &W'A9E.'

Sometimes a guy can get crossed up in a routine operation, like when he's
greasirg a 5-ton bridge transport truck.
Sure he lets go with the grease gun on the fittings until he spots grease ooz-
ing out where it's supposed to-no sweat.
But, this deal won't work on the loading roller, covered in LO 5-8063 (8 Dec
52), and there's a lot of these trucks around with popped roller bearing seals
to prove it.
If you lean on the gun, the bearing gets packed to the hilt. There's no place
for any extra grease to go so-pow out goes the seal. -Couas oNCI A

An easier way to face this exception
to the general rule is to take out the
standard grease fitting and put in a
S"-pressure relief type.

-The fitting you want to latch onto
is listed in the Federal Supply Catalogs,
I Class 4730. FSN 4730-330-0111 will
get you: Fitting, lubrication, pressure

Then when you make with the
grease gun the fitting will "pop"-
not the bearing seal.






STOW IT RIGHT
You say you don't know your stem from your stern when it comes to stow-
ing gear in your 27-foot bridge erection boats?
No sweat.
Just remember you have a storage compartment in the bow ... or front of
the boat for your gear. Accessories for the boat like post lights, running
lights, spot lights, life preservers, ropes and cables go in this compartment.

Orderly, easy to reach and ready to load. .
You can keep your maintenance and supply publications that way in a port-
able, stackable, weather-tight, homemade library.
You can make the box-shelves out of scrap materials (plywood is good, too).
The dimensions shown are good, but you can scale 'em out to your needs. Just
remember to keep 'em light as possible ... and try for water-tight boxes with
tight fitting lids. Then all you have to do is close 'em up when you ship out or
take to the field.
Line the boxes up in some safe place in the working area, just so the books
are within easy reach of those who have a legitimate need for 'em.

LINE ITEM NUMBRt

A LI ALL THEIR OWN
Just a minute, Pardner, if you're ridin' herd on tool
sets or kits. Better pull up a bale of straw and take a
load off of your feet 'cause here's some news that's going
to interest you.... '
There's a DA Circular 725-5 (30Jun 64), "Removal AN
of Components from Assemblages and Sets of Equip- rTHNk y
ment," that affects your tool kits and sets. 60 VAtS .
The gist of the circular is that some generators and / PAWPNS
compressors are no longer a part of many tool kits and
shop sets. They became separate line items of equipment
as of 1 Oct 64.
These changes will show up in your supply manuals.
The TOE's and TA's are getting revised to show the
compressors and generators as separate line items of
equipment.
This means that when you're ordering a tool set or
kit that formerly had the compressor or generator, you'll
have to requisition the deleted items individually.






NO DISINFECTANT, PLEASE


It's real simple to clean the food-
chopping board (FSN 7330-281-4695).
After you use the board (and the sooner
after use the better) use a detergent
solution or hot soapy water and a stiff
scrub brush on it. Then rinse with clear,
hot water.
You want to use enough water to
rinse off the detergent but try not to
get the board soaking wet all the way
through. And, don't dunk it in water.
The more water you use, the more
chance there is of the layers separating.
Once that happens, you have to get rid
of the board.

That no-dunking bit also goes for
wooden utensils and knives with
wooden handles. Water causes wood
to expand and, as it dries, the wood
shrinks and leaves open seams or cracks
-and a cleaning problem.


ALARM PROTECTION
A standard wooden footlocker, some suitable boards for partitions, and a
little carpentry are all it takes to give your VG Alarm E41R3 (FSN 6665-671-
9584) and its components a good home. The sturdy box also solves the han-
dling problems you have when you keep the alarm and its components in card-
board boxes.
The box takes the alarm unit, reagent kit, the two batteries and the elec-
trical headset and special purpose cable.
Your property disposal center may have some footlockers you can use.

DD FORM 1150..THE H/R's HELPER


Nothing fancy... Just the facts.
That's all the supply scoop you need on DD Form 1150 "Request for Issue

The multicolored, three-copy form is OK'd as the issue and turn-in form twixt
property book officers and their handreceipt holders. See para 13c, Change 4
(27 Nov 63), AR 735-35 "Supply Procedures for TOE Units,Organizations, and

But don't get shook-up by the form's various blocks and spaces. When it's

When you can't make your AC con-
nections any other way, you can always
go in for some of that "local procure-
ment," right?
Right. But with the usual care and
caution.
Some of those commercial-type plugs,
or connectors, just weren't made to put
out in a military manner. You run
across such things as light plastic ma-
terial, even lighter wire, no tensile
strength, and all that sort of thing.
Doesn't make for good, satisfying con-
nections, what with all those repeated
insertions and withdrawals that power
plugs are prone to.
Now your military-type (MIL-C-
3767) male power plug or connector
is designed for real rugged use. It comes
with a clamp to grip the cable, so you
don't have to rely on the conductors
alone for tensile strength. It's well in-
sulated, with rugged prongs that can
take on any ol' receptacle without get-
ting bowed in the knees. And as you


---------
know, there're some mighty fancy fe-
male receptacles stuck around on the
walls of some shops, plants, supply
points and such.
Let's see, now, where were we ... ?
Federal Supply Catalog C5935-IL-A,
Connectors, Electrical (1 Aug 64) lists
more connectors than you'll ever know
what to do with. But here're some that
you can get a lot of use out of:


Connedor, Plug, Eledrical (power, nonpolarized
parallel-bladed) Type UP 120M (2 blades), FS
5935-518-9653.








Connector, Plug, Electrical (power, 3-wire, ground-
ing type) Type UP 121M (3 blades), FSN 5935-
636-7145. This has a fixed ground blade and can-
not be used in two-blade receptacles.

M W__ I 7rnW


The whole point is, it's much better
to get your AC replacement plugs
through the regular supply channels,
and to resort to local purchase only as
a last resort.

qcz4 ACCEPT NO SUBSTITUTES




Substitutes are no go when changing tires or wheels on your MHE. Be sure
you use the same outer lock ring for the rim or wheel you took off.
Got word that one guy switched the outer lock ring from a Baker RJF060
rough terrain forklift to a LeTourneau-WestinghouseM-20 tractor-towed crane.
Sure, the substituted ring looked the same and snapped into place without
sweat... but, it wasn't identical. As a result-it gave way under heavy load.
Now, there's a guy in the hospital and his equipment's on deadline.
So remember: use the right part-always!

directly below. This potent mixture can
enter the first stage air filter ... or cor-
rode the filter and air shrouds under
the box.


Sure, removing the batteries before
pulling PM takes a little more time and
muscle, but it'll pay off when your
birds are ready to take wing.






BE A TACH WATCHER










Keep your eye on that slot where hours of engine operation are recorded on
the tachometer of your 10-ton cargo truck or truck tractor.



5 30"1



'*' (~ WILL GIVE VOU iL)' \

You need the readings in hours from the tach--as well as miles from the
odometer-for DA Forms 2408-1, 2408-2, 2408-3 and 2408-10.
Some wheeled vehicles don't get readings in hours, but these 10-ton bruisers
do-but definitely. For a quick clue on why you need the hours, take a look at
the vehicles' ESC's. See items 16, 17 and 18 for the cargo truck in TM 9-2320-
206-ESC/1 (Jun 64) and items 17, 18 and 19 for the truck tractor in TM 9-
2320-206-ESC/2 (Jun 64).
To make some of the ESC checks, you may need a look, too, at the vehicle's
DA Form 2408-6, 2408-8 or 2408-10---especially if the engine or maybe the
transmission and transfer have been replaced.

A good ground is a must for safe
generator operation. To be sure it'll do
the job, here's what you need: Rod,
ground, 9-ft long, 5/8-in diameter, FSN
5975-642-8937, and Clamp, electrical,
FSN 5975-243-5861, and Wire, elec-
trical: No. 6, AWG, 10-ft, FSN 6145-
189-6695. Without this ground rod your
generator hook-up isn't complete.

Are your equipment periodic mainte-
nance services scheduled right on DD
Form 314? If not, a quick check in DA
Cir 750-3 (12 Jun 64) may help to get
'em back in line. The circular lists the
latest publication changes which cover
periodic maintenance services.

Lest ye get your DA Form 17 back
marked "CI" (item cannot be identified)
when you're trying to order more copies
of DA Pamphlet 750-38, "Improved
Army Equipment Records Procedures"
(25 Aug 64) better cite U.S. Army AG
Publications Center (Baltimore) Bulletin
42 (26 Oct 64).

Be sure you aircraft quys never toss
out any old platinum tipped spark plugs
or magneto breaker points. You'll turn
them in to your support who'll see they
get reported to GSA, just like DA Cir-
cular 755-5 (18 Dec 64) says.

Having trouble tracking down a re-
placement for the TDH-39 headset used
with the AN/TSW-2 battery control
central? Relax. The TDH-39's been re-
placed by the H-144A/U, FSN 5965-
682-2769, which is listed on page 3 of
TM 9-1430-501-12P/1 (15 Jun 64).

Now hold on one minute there, Sonny.
Don't go slippin' a ringer in on those
1-1/4-amp power pack and jack field
fuses of your SB-86/P switchboard.
Some Joes have been known to substi-
tute as hot as a 5-amp fuse, and the
extra juice those jobs let through might
just kinda burn up the switchboard. If
you don't have a 1-1/4-amp job, do
your best to get one. They're in TM 11-
5805-304-20P (Jul 63) under FSN 5920-
284-9457 and 5920-284-9454.
