Dear "Russ",
A piece of equipment's
no better than the man
taking care of it. kou
are doing a fine job of
caring for those genera-
tors.
When generators have
to operate 23 hours daily,
it doesn't give you much
time for PM. So it does
prove one thing. You're
making the most of that
one HOUR...
I want to take my hat
off to you for taking
such good care of those
generators.

POINTERS TO PONDER

'-Combat rnpes can's emphasize rhis /' u
enough: Clean the gas port in the bolt
carrier group after e'erN dai of firing
-and lake it real ea. wilh Ihe lube.
Dirt and powder-fouling-plus an I \
overdose of lube oil-will give iou a
sluggish rile. .Numbah 10 Thou'
in a combat situation!
So. when You get sour baby stripped
for cleaning, like it sass in para 3-2' in
Change 4 to sour TM 9-1005 249-14 I lun 6-4. take an extra 5 seconds to get
at the port hole do"n there in the front end of the gas tube. Like so:

1. Work a bore blushful 2. Then use a pipe deaner or the like to poke the gook out of the port.
iof bore leaner around In a pinch you could use a stripped green twig or stem of gross to do
inside e the tube. the job as long as it won't peel in therein t o't use wire, though, or
you might saotch the tube and set up worse trouble later on.

2
j l~---Z- E;Fs~

ki

Now, when you come to lubing, do it like so:

1. Put one drop of oil (count it on your right 2. Put one drop in each of the bolt ring holes
thumb-one!) in the gas tube. This one (count 'em on each thumb!). This is the
drop'll also lube the outer surface of the way to do it in a combat situation, say,
tube in the receiver when you mate 'em. but if time is plentiful you'd be better off
taking the bolt apart and putting one
drop on each side of the bolt rings and
then work it in good with your finger.

ONE
DROP
IN EACH

Whatever you do, though, never dunk your bolt in lube oil-and never
pour lube oil into the firing pin well, like some guys do. This'd make it like
a hydraulic buffer, meaning it'd slow down the forward movement of the firing
pin and give it a light touch on the cartridge primer.

I s r 3. Add a light coat (brush 3 drops, soy) on
all surfaces of the bolt and bol carrier. ^
And that's all!

Another couple places you won't want to forget when you're cleaning your
weapon are the claw under the extractor in the bolt group and the locking lug
recesses on the barrel extension down in the lower receiver. If dirt and crud

CLEAN
THE
CLAW
collect under the extractor, the claw won't be able to snap over the rim of a
cartridge case. And if gook and brass chips from cases gather in the recesses,
your bolt action will be stymied. So, bear down on your bore brush in both
these places.

TIPO While you have the bolt group apart-and after you clean
S 'em-make a practice of eye-checking these parts:

BOLT- Cracks or fractures, especially in the cam pin hole
area. This bolt has a great service record so far, but it pays to
be on the lookout for that first sign of weakness. Don't worry
about any discoloration you find there, though. It's harmless.

CAM PIN- Cracked, chipped, missing. Be sure it's in place
When you put the parts back together. A rifle could explode if
S you fired it with the cam pin missing.

FIRING PIN Bent, FIRING PIN RETAINING PIN -
cracked, blunted. Bent, busted, badly worn. If one
or both tangs are busted, there's
no sweat as long as it'll hold the
firing pin in place. But, be mighty
careful you don't lose it when
you're doing PM. A rifle fired with
this pin missing may fire once -
but that's all. The firing pin would
then fall out and no-fire!

It you're ha ing trouble with the front ling
s~i\el falling out, it means the spring pin's
getting weak like ill naturally do after a
spell. No sweat. though. Get sour armorer to
stake it thisawa .
Stick the spring pin through the swvsel. mak-
ing sure both ends of the pin are about flush ith
the outside surfaces. Then take a center punch
and rap the area about 1/ 16 inch from the swivel
spring hole. Stake both ends for good measure.

world-wide--but they could get mighty scarce \/
in your own sector. So, protect 'em from dents i
(soft aluminum like that can't take rough treat- \

When )uu lire blank inmmo in )our Mllt rnlk
without using your blank firing attachment you
get a lot of carbon in the gas cylinder. You can
head this off by turning the gas cylinder valve to
the closed position.
After you fire blanks, and before you fire ball
ammo, you want to open the spindle valve.

CLOSED

OPEN
The valve can also be open when you fire blanks
with the blank firing attachment on the end of the
barrel. When you use the attachment, enough gas
is kept in the bore to operate your rifle semi-
automatically or automatically if you have the
selector lever on your rifle.

Pages 14 .nd 3" of )our Ml-1 rifle's TIM 9 I(05-223-12 (8 Feb 65) tell you
to make sure your weapon's cocked before you put the safety on. Why?
Trying to pull back on the safety with the shooter uncocked can mean a
busted safety tip that's why. When the rifle's not cocked, the tip of the
safety's leaning against the bottom of the slot in the hammer and pressure
on the tip can break it off.
You might not even notice a small piece that breaks off not right away.
The first sign could be something in the firing mechanism getting jammed by
the broken tip.

It's a smart operator who checks out his M60 machine gun before he goes to
play a tune with it.
And one of the things he looks at as if it mattered because it does is
the cover for the buffer assembly. Could be he'll find that the lock pin is
making its way out of the buffer because the cover has moved.
Not that a loose pin will make a lot of difference in the way the gun oper-
ates. But if it drops out, and you fire the gun, you'll need a box for the buffer
assembly pieces.

In other words, make sure the cover is twisted around so that the pin is
where it belongs.
And don't let itchy fingers get the best of you when you have the buffer in
your hand. It's up to your support people to take it apart not you.

Another thing... if your unit didn't have the parts manual which identifies
the parts you need, then it's likely your unit's order on the 12-Series DA Forms
for automatic pin-point distribution is not up to snuff.
So, get out your unit's copy of all the 12-Series Forms and find out how many
copies are on order for each type of equipment your unit has. If somebody didn't
order enough, then you need to send new 12-Series Forms to the publication
centers.

212-TON MULTIFUEL TRUCK...
GROUND MOBILITY SHORT CLUTCH ROD
CAuL
WME
SHORTY'

Look for a short clutch control rod if you're havin' trouble adjusting the free
travel of your 2V2-ton multifuel truck's clutch pedal. This goes for the M35A1,
M35A2 and all other trucks that have the M44A1 and M44A2 series chassis.
Some control rods have popped up with more than an inch missing from the
threaded end. Measured in a straight line through the threaded end (not follow-
ing the bends), the control rod should be exactly 13 inches from the threaded
end to the center of the holes at the fixed yoke end.

1 11 7 31 4 1 6 1 8-- "- ---i -i1

20 (Apr 65). But you may not be able to get that much if you've got a short
control rod.
A short rod should be replaced by a new one. You can get it by ordering
Rod: control, w/yoke, assy, FSN 2540-752-0977. It's listed in TM 9-2320-209-
20P (Jan 65).
If your rod's OK and you still can't get the right free travel adjustment,
check out the linkage for binding. Then get direct support to give you a hand
in making sure the release bearing and bearing sleeve are working free. If
they're binding, they'll have to be taken apart and lubed.

Dear Editor,

Finally, we cannibalized a Hitch-

mounted it on a bracket like these S

We have since found out the Hitch-

ENGINE MODIFED?...
2 WAYS TO TELL
Ever so often it becomes a problem
deciding if an engine has had a modifi-
cation applied to it. Particularly when
the engine, or the entire vehicle, is a
replacement item.
Well, there are two quick ways to
tell... by data plate and log book.
First, TB ORD 1030 (Oct 63) shows
the "Installation and Use of Overhaul
and Overhaul/MWO Data Plates." So,
in the case of a modified engine, a data
plate like the one on page 2 of the TB
should be staring back at you from the
engine block.
For backup, your vehicle log book
should contain a separate DA Form
2408-5 MWO Record for the engine
only, showing a completed entry de- the engine itself
scribing the same modification, modification. Bu
If both the data plate and MWO job, you'll just h

Take a look at the pintle on your
M60-series tank or M728 (TI 18EI)
combat engineer vehicle. Is the pintle .li
sleeve lube fitting on top of the sleeve? FIlING
If it is, then take out the bolts and 5
give the sleeve a 90" turn to the left, l
then install and tighten the bolts again.
This'll give the lube fitting some pro-
tection from falling objects such as

CoMMUNICAroNsS THE CASE OF THE
WEDGED LOCK PLATE

VI,, S

Is your IM-174/PD radiacmeter getting robbed of service 'cause the lock plate
on the empty battery box is wedging in the case?
When the BA-1288/U and BA-1318/U batteries are out, the lock plate can
jiggle off the lock plate screws and settle tight inside the case. Diggin' at it with
a screwdriver or other pointed tool can damage the plate and radiacmeter case.

SFreeit"vwh A~ 4, flthedd screw. it the
siiew. o iiti oe. i:: the. lodring holes il ..

Your best bet is to put a piece of
plastic insulating tape (FSN 5970-644-
3169) on the lock plate, securing it to
the side of the empty battery box. The
tape's listed on Page 55 in the GSA
catalog (Jan 66).

A good cure for a switchboard with the Asiatic hiccups might be a mixture
of alcohol and varnish.
Sound a little rich? Read on.
Whether you're sweating it out with Charlie or just plain sweating, bet a
nickel the humidity's high. That soggy feeling breeds corrosion which has
been getting to the contact springs of the TA-208/P and TA-220/P cord and
operator packs of the SB-86/P switchboard.
The kind of corrosion you get where the VC come calling can No. 10 your
switchboard soonest. But, there's a PM cure that'll make it No. 1 and keep
it that way with minimum sweat on vour part.

Like, at the organizational level you can swab the contact springs at least
once a month with rubbing alcohol (FSN 6505-299-8095) or cleaning com-
pound, (FSN 7930-395-9542). A good dabber is a cotton swab, like Applicator,
FSN 6515-303-8250.
After you've cleaned the springs, use a cotton swab to dab them with varnish
(like moisture-fungusproof varnish FSN 8010-840-7494). Remember, a little
varnish goes a long way, so try not to slop it on. Also, stop at the bend in the
spring so's not to get it on the contacts. Varnish makes a good insulator -
which you sure can do without on the contacts.
You'll find the varnish in SB 11-573 (Feb 64), Painting and Preservation
Supplies Available for Field Use for ECOM Equipment.
Because of high humidity damage, the cord and operator packs should go
to general support at least once a year for complete cleaning and re-varnishing.

Dear Specialist H. L. G., -
There's no FSN for the clamps. They're not maintenance items, so units have
to be real careful about misplacing or abusing them. Replacement clamps have
to be made by your support or depot. You might even get lucky and scrounge a
matching clamp from your support's common hardware or by local purchase.

Are you about to boost the signal
along the line with your AN/TCC-II
telephone repeater? That's fine.
While you're setting the controls in
the Ji and J2 end assemblies, make
certain the O-ring (preformed packing)
is around the bottom of the controls
access port cover. A missing O-ring
(FSN 5330-290-8806) will let moisture
in and corrosion'll be close behind.
Then, whether the repeater's up a pole
or on high ground, it'll make a bum
booster.

When it comes to spot painting elec-
tronic test equipment, forget the Tom
Sawyer method of whitewashing every-
thing in sight.
F'rinstance, with a TS-352()/U
multimeter or TV-7()/U tube tester,
touching 'em up with paint where the
sets need it is supposed to head off rust
and corrosion, not create a salvage
problem.
For touch up work your best bet's
to use a brush and go sparingly with
the paint.

FOR TOU1I-UP.

If you have to use a spray can or gun
make sure sensitive areas such as dials
and air vents are taped. Same goes for
nameplates, decals and other markings.
Paint in the wrong'place can damage a

YOU
DA Form 2404 has 2 operator/crew uses. (1) It's a SWEET
worksheet for making Before-During-After-Operational 2 04!
checks-let's call 'em BDAOC. And it's for making
Equipment Serviceability Criteria (ESC) ratings. As an
operator or crewman, you'll be doing the BDAOC, and
-if the equipment is required to be reported on DA
Form 2406-you'll use DA 2404 along with the ESC
TM to make the numerical rating for each point.
For both of these operator/crew uses of the DA 2404,
you fill out blocks 1 thru 5 the same way. But entries in I
blocks 6 and 7 are different.

Even though uncorrected faults are

USING THE RIGHT OIL

That's LO's gospel, and you'd better believe it. It tells the one and specific
kind of oil you want in that air-shoving end. Some types you may have trouble
finding are:

MODEL OIL TYPE FSN QUANTITY
Davey M-210-RP 21901 9150-235-9061 5.gol drum
Joy RPA210 series 2110 9150 223-4137 5 gal drum

Dovey M25'URPV and
Joy 250 series

2110111

55 gal drum

That 2110TH is popular stuff in the air-cramming business Ingersoll-Rand
DR315s and DR-600s use it too and don't forget the TH part of the spec.

CHECK OUT YOUR FILTERS

KEEP YOUR
EYE ON 'EM.

You've got 4, and 3
of them can gang up on
you any time. That is,
intakes on engine air
and compressor air can
choke up within min-
utes of each other, and
you'd better be ready
with fresh underwear
for both when it hap-
pens. Then you have to
watch what goes on in
that oil separator ele-
ment-it's strictly not
built for overtime work.
The 4th one, on the
engine oil, you can't ne-
glect either. --

Here is the word on the critical ones.
ITEM MFR CODE PART NUMBER

What, only one FSN? Correct-but you can order 'em by part number. And
there's a little trick that'll provide life insurance for those air intake insides,
especially on your Davey, if you don't have a muffler.

If that's the make you've got, put a
55-in length of exhaust extension on
in place of the rain butterfly -it's FSN
4720-595-4146, hose, metal, inter-
locked, unpacked. And point it away
from the air intakes.
FSN 2990-225-4838 gets you a muf-
fler from Fed Cat C2990-IL-A-CB6
(Aug 66). When you get it, take off the
55-inch extension and put the muffler
on-and put the rain butterfly back.

No matter what pedigree rig you've
got, but especially if it's a Davey 250
CFM, you'll need a supply of spare
innards if you're to work in the field.
Washing the Davey's engine air filters
in non-sudsy cleanser is fine--but they
take 2 days to dry.
But wash, change or whatever, those
filters are there to protect the insides

of your rig. Dirt in the air lines and
exhaust soot in your carburetor will
make a hangman's noose for sure-
and dirt in that aircrammer equals
stuck rotors, broken vanes, bent shafts,
and an unhappy crew staring right
straight at you.

HALF HOUR AN' YOU'RE STILL NOT
STARTED T-O-U-6-H. THE PRE-
START CHECK-OUT 1S THE MOST,
I AND TIGER, WE'VE GOT MORE
S TO DO!,

CRANKCASE OIL- Level right? Hour-
meter say it's time to change?

ELECTRICAL SYSTEM-Terminals tight?
Electrolyte over battery plates? No bare
wires that need tape? Generator belt
sound?

RADIATOR- Coolant within inch of
top? Hoses tight, no drips or cracks?

ACCESSORIES- Fire extinguisher
charged? Tools, pubs and forms in
order? Bolts and clips tight?

FUEL SYSTEM-Tank full? Sediment
filter clean? Joints tight?

CHECK OUT YouR
COMPRESSOR... BEFORE YOU.START
THAT'S JUST HALF
OF YOUR ONCE OVER!
NOW BENP A GAZE TO
WHERE THE MUSIC COMES
OUT, THE AIR-CROWPING C
END!!
If you're new on the job or if somebody else has been in the saddle before,
or if you just plain prefer this work to diggin' foxholes, check 3 more things-
OIL SEPARATOR LINES Solid, no kinks or breaks?
Beenorv ed by COUPLINGS Facings smooth, gaskets good?
kets light? r ---

If support's not around, and the rec-
ords are messed up so you can't be sure,
you can feel that oil separator's pulse
by taking the lid off. If it's smeared by
tough varnish, not just normal sludge,
that's a red flag and a sign for support
cleanout and oil change.

NOW LET'S START

SHUTDOWN
Closing up the store the right way is another big piece of insurance. Fact is,
you can't start right the next day unless you stop right when shutdown time
arrives.
With the load eased off, you cool at
idle 10 minutes. If there's an Idle Con-
trol, use it. You can use up your excess
air to clean out your tools, blowing out
muck and water.

has a small sump, and it's got a temperamental oil inlet valve on the older

sheared vanes when you kick 'er over again.
