what happens?
So dirt and water sneak into the left and right brake control lever shields and
make a glop that glugs around inside the shields.
BRAKE BOOT GASKET
NEEDLE APPLY B (BELOWS)
BEARING ARM




The glop rusts the needle bearings and makes the brake apply-arms hard to
S work. It also rusts the quick disconnects and tube assemblies. In freezing weather
the glop freezes hard as concrete and you have to pull the pack and chip it out
before you can use your brakes.
L -.. There must be an easier way.


Have the pack pulled and the shields
taken off and deglopped. Your me-
chanic will also clean and lubricate
the needle bearings in the brake-apply
arms. If they're too far gone he'll be
happy to put in new ones. They are
FSN 3110-120-3085, Item 7 on page
2-167 of TM 9-2350-215-20P (Jan 65),
and Item 13 on page 2-305 of TM 9-
2350-224-25P (Jan 66).
If the rubber protector or cover
gasket is damaged or missing, the me-
chanic will replace it.
INSTALL GASKET SO
AS TO KEEP GLOP OUT
AIL \ .


SHave the protector checked every Q
service. Also, look it over when you
make your after-fording check of the
brake linkage like it says in your vehi-
cle -10 TM. If there is no glop inside
it you won't have to have the pack

pulled and the brake control lever
shields cleaned out.
Mud and water can build up in the
engine compartment if the drain valves
don't work right. Naturally, this in-
creases the chance that some glop will
work through the rubber protector
(boot or bellows) and on into the
shields. OF
COURSE
I'LL DO
IT! HO
HO HO/





Your smiling company mechanic will
be glad to check the drain valves every
Q service and make sure they're work-
ing right.
Once you know they're OK, use 'em.
Before you drive the tank make it a
habit to close both drain valves and
when you stop at the end of the day,
open 'em up.
Follow this anti-glop program and
you can put a permanent freeze on your
frozen brake problems.

is being corrected. The only number is
8382077.




When you order your padlock set for your M60 tank
(TM 9-2350-215-10(Feb 65), page B-14), ask for FSN 5340-
682-1505 if you can't get the old one, FSN 5340-682-1504.
This new padlock's available at the Defense Industrial Sup-
ply Center, Philadelphia, Pa.


LOG BOOK NUMBERS

The data plate serial number is the one you use for
your log books and other records. The number stamped
on various parts of the hull is just so you can get the
part back on the right vehicle if it is ever taken off.
This goes for the M114 Scout vehicles, the M108 and
VEHICLE DATA M109 SP howitzers and for all vehicles that have a
PLATE number stamped on the hull that's different from the
number stamped on the data plate.




6TN BATTERIES...
WOOD SPACERS HELP HANDLES









I15 ABOUT
TIME!!


Handles are handy when you want to hang on to batteries by hand. But
they're in the way when they hang up like on the tiedown channels in
some combat vehicles.
Seems the latest issue 6TN-type batteries no longer have handles that can
drop flush with the battery top. The handles stick up just far enough to be a
problem for the battery tiedown channels in your M107 SP 175-MM gun,M110
SP 8-in howitzer and M578 light recovery vehicle.
An easy way to handle the interference situation is to make up wooden spacers
to fit under each channel. Then glue a rubber strip to the bottom of each spacer
to cushion the battery top.
Cutting a 7/16-in slot in one end of each channel will also make it easier
to put the hold-down cap screws in place. Adding the spacer will mean hunting
up longer cap screws .. about 3/-24UNF will do. You might try the country
store for 'em.
Now that we're on the supply side, the rubber strip you need for cushioning
material is listed under FSN 9320-819-8964 on page 4.42 of Fed Cat C9300-
IL-A (Oct 65). Glue it on with the adhesive, rubber, type III, MIL-A-5092, listed
in Fed Cat C8000-IL-A (Jan 66) on page 81. FSN 8040-262-9011 for a pint and
8040-515-2250 for a quart.

M114 I MI14AI TENS NER r ICS '
So you've just had the new accessory belt tensioner (10954321) installed on /
the Ml14/MI4AI carriers .
Bully for you! Only thing, this is no I&F item.
If you I&F it (install and forget) you may wind up in a bind with a bind- --
ing belt tensioner.
If the tensioner binds it can throw the belts just like the old tensioner did. TENSION RIGHT
This could be a little bit fatal in case your vehicle has not been modified with To make sure you have the spring tension right and no slack in the belt set,
the direct drive pump kit, MWO 9-2320-224-30/8. measure the distance from the plunger rod pin to the bracket. With a new belt
The tensioner binds because it gets full of dirt. If you can't con a mechanic this distance should be about 2 inches.
into keeping you out of a "bind" it's a cinch do-it-yourselfer. If the distance is less than W inch and the adjusting nut is bottomed out,
t -it's time for new belts depending on wear of pulley groove.
Just ad the am and adjusting nuts down Pull out the two cotter and devis pins nd If you still have trouble adjusting the belt tension like the plunger rod
Smove the tensioner for denning. won't move when you tighten the adjusting nut, or the rod won't stick out beyond
Sthe bracket tap the top of the bracket softly with a hammer and the rod may
shove out.
Still no luck? If tapping on the bracket won't get the plunger rod moving
have DSU take the tensioner apart and remove the nicks or scratches from the
plunger rod or bushing, or whatever else they need to do to make the rod work
like it's supposed to.
--- If plunger rod is bent, they'll replace the entire assembly since repair parts
are not items of issue.
Without taking it apart, swish the ensioner around in dry cleaning solvent The tensioner assembly is a little goody not in your -25P TM yet but you
or mineral spirits paint thinner, then dry it and put it back in the vehicle, can order it anyway as FSN 2930-789-0421 (10954321).

OK..DK Z0, I'LL FACE




EMERGENCY ONLY
All mechanics were taught that the arrow stamped on the tensioner bracket
must always face toward the spring. This is still true.
In an emergency, tho, you're allowed to put the bracket in so the arrow faces
away from the spring.
SYou'd only want to do this when the belts are so badly stretched you can't
get tension on them in the regular way.
SRemember, this is only for emergency use when you don't have new belts
and you have to keep going with an over-stretched set. As soon as you can get
S new belts the bracket has gotta be put back the right way with the arrow facing
toward the spring.

NEVER ON (HYDRAULIC) BRAKE LINES

Copper tubing is not what you want in your tactical
vehicle braking systems. It may be OK for some of the
f l air lines, but it won't hold up under the heavy pressure
,i "- of hydraulic fuid. You're better off with the steel tubing
listed in Federal Supply Catalog C4710-IL-A (Aug 66).

Some 5-ton truck jockies and mechanics have been curious about the mean-

dope: EN for engine, D for diesel, T for turbocharger, 67 for 672 cu-in displace-
ment and 3 for military. Now you can sleep sound.

RECRUITME T
OFFICER NOW







No one ever confuses military with commercial design wheeled vehicles.
That's because you can see they're alike as cumquats and bananas. But when it
comes to what kind of maintenance to pull on a tactical vehicle when assigned
as an administrative vehicle, your eyes start getting watery.
Well, not any more. Now-at last-you can go to para 44b in the new TM
38-600 (May 66) Admin Use Vehicle Management, and be told to follow the
maintenance procedures in each tactical vehicle's own manual regardless of how
it's used or assigned.


HOOD BUMPER RIVETS

You can get rivers thru your support for installing rubber bumpers on the
top hood panel of your G742-series 21-ton or G744-series 5-ron truck. The
river, FSN 5320-011-0076, is in the very latest TM 9-2320-209-35P and TM

GOT A DRAGON WAGON?
Outfits that have the M15A2 50-ton semitrailer can now up-date their on-
vehicle materiel (OVM).
Since the trailer was converted into the M15A2 from the MI5AI, it no longer
needs all the items listed in the OVM section of Ord 7 SNL G160 (Aug 52).
The SNL, by the way, is still the parts manual for the M15A2 semitrailer. \
And TM 9-767 (Feb 44) is still the A2's basic maintenance manual.
Here's the %as the OVMN sacks up-

So one day in Vietnam a couple guys tried our this idea, see. The jury-rigged
some 2.75-in rockets to the M6 (quad 7.62-MM machine gun) subsystem. Good
old Huey UH-1B put the Numbah One zap on Charlie that da\.
Bye and bye this jury rig got to be official through M\1'O 9-1005-2.-1-30/4
(Oct 65) and today you have the XM16 subsystem.
--4-_ I XN.
A~ ",5,I~/~u~


Most of the stuff you know about the M3 and the M6 is still good (including
a lot of what was in PS 154 and PS 156). But not all of it. F'rinstance, the XM16
totes a couple different types of launchers, has a beefed-up cartridge drive, an
intervalometer and a few other refinements that make it tougher than its
ancestors.
This article aims to spotlight some of the potential trouble spots and to offer
tips that'll help you MOS 45J20's and crew chiefs-and yeah, pilots, too,-to
keep your battle-born baby lethal.


ELECTRICAL CABLES -Not plugged in
and tightened; bent pins in the con-
nector, frayed or cut or badly-worn
wiring, especially near the connections.


HYDRAULIC LINES-Oil leaks from
loose connections or cut hoses.
And keep your hydraulic stuff clean.
Use those rubber dust plugs every time.
If dirt gets into these hydraulic lines,
it could foul up the chopper as well as
the armament system.






The LAUNCHERS
You'll have either the cylinder-type reusable but non-repairable XM157 or
the cluster-type reusable and repairable XM158. They're light, easy to hurt, so
be warned. When you inspect 'em, examine each of the 7 tubes in each launcher


the same way-with extreme care. r


>M I57 LAUNCHER--Dirty, bent or
cracked center contacts; corrosion and
rocket residue in the tubes, especially
in the rear half; dents in the cylinder
that also dent the tubes; bent or loose
suspension lugs; missing or beat-up
front and rear receptacle covers.


XM158 LAUNCHER- Loose (should be
hand tight) or damaged suspension lugs;
cracks in the hard point and segments;
missing, loose or damaged nuts, bolts,
pin; torn modification straps; tubes
dirty; firing-arm connections loose;
busted lock wiring; igniter head dirty.


If any part of the XM157 launcher's badly hurt, the whole thing's got to be
scrapped.
You'll find the dope on replacing damaged tubes and other parts of the
XM158, together with a list of repair parts, in Change 1 to TM 9-1090-201-12.

TM tell you about outside cleaning.

don't hurt the contacts ... push all ihe
way through to the contacts, then rotarc
your brush and pull it out again.

To lube or not to lube-and how much lube?
Big questions around the launcher and rack assembly. Huey really blows up a
dust storm with that rotor and dust and grit make a mighty tough abrasive
when mixed with oil. So-o-o-o, after you clean all parts like prescribed in the foot-
notes of your Lube Chart, here're some thumbnail rules on lubing or not lubing:


Put a dab of LAW (lubricating oil, weapon, FSN 9150-292-9689, 1-qt can)
on a clean rag and then just wipe the parts off.
Keep this same thought in mind when you're cleaning and lubing your machine
gun and other components with reciprocating parts. Too much oil invites trouble.
Incidentally, you never touch the inside of the bomb rack. Especially, don't let
anybody try to soak it in cleaning solvent. Too many electrical parts in there!







the JETTISON
Hairy situations multiply like rabbits
if the pilot ever has to drop his load and "HnOrL
the launchers refuse to go. Now, it's 1,

to clean and repair 'em -once a week's
not too often. Here're a couple other-
ways you can make for certain the jetti- "
son system's OK and will work.


r Inspect and test (manually and elec-
S rically) before every mission.
J' Eye-check for cables that're frayed,
!'3 need lube, or are too loose or too right
( 2-in slack needed on each side of the
ship); bent pulleys, loose or bent brack-
es (tell the guys to keep their feet off

RR ROCKETS



Your XM16 subsystem tosses the same 2.75-in FFAR's used by the XM3 ..
and the rules for using them are about the same.


ROCKETS- Make sure they're modified (scarffed) no other kind will do; check
'em for dirt, grease, wetness; see if the lockwire tab's missing or there's a gap
between the rocket motor and the warhead after it's been tightened.
Watch out if you get one of those rocket motors TOSS AWAY
with a rubber ring under the lip of the warhead SHIM AND
shipping support and a fiber shim between the RING
warhead shipping support and the warhead closure.
Throw this ring and shim away before you thread
the warhead to the motor-else, they may swell up
and cause the warhead to work loose in flight.
When you're tightening the warhead to the motor tube, use 2 strap wrenches
(FSN 5120-242-3249). Fit the first within 21/2 inches of the motor tube and the
second around the warhead. Then tighten the head as much as you can without
causing the head closure to turn or to force the visible lockwire in or out of the
elongated hole in the motor tube lockwire groove. Of course, if the wire moves
within the elongated hole, that's normal.
S/ MAKE CERIAIN IHAI MOTOR IUBE

But be real careful you don't force the lockwire tab down into the motor lock-
wire groove or out of the elongated hole. The enlarged tab traveling through
the groove would bulge the motor tube and make it unsafe to fire.
Never end the job without double-checking to see that there's no gap meaning you can't
seat the warhead on the motor tube within a full turn or that the lockwire tab's out of the
elongated hole. Either one automatically makes the rocket NG.

SHURRY! Incidentally, in a combat situation,
BUT BE some guys save time tightening the
S CAREFUL/ warhead to the tube by hand- loosen-
V_ ing the warhead half a turn, then
snapping the motor tight. This is OK
in a real emergency, but, even then,
doublecheck for tightness, gap and dis-
placed lockwire tab. Doesn't pay to
hurry up--and then blow up!


fiRST, THINGS fRST
The XM157 and XM158 launchers require different loading and unload-
ing procedures, but the steps you take before you get to the loading and un-
loading stage are exactly alike for both launchers and, for every guy's
sake, never miss out on doing 'em.

at the tube, don't load the rockets. Get

. Heads-up Tip: Never forget, whenever you're loading or unloading your launcher, make sure
the launcher's facing away from other aircraft, work areas, ammo dumps, and such-like ..
and make sure nobody's standing in front of or behind it.
S You've got to be mighty careful handling these rockets... or you might bust
the propellant in the rocket motor. This could cause erratic flight and rocket
break-up as well as other damage.

ODDS 'N' ENDS
Supply Tip: Take it from the guys over there-- a 2-bit item is worth a fortune
if you need it and don't have it. So, play it smart, don't take a chance on running
out of repair parts. Keep up to snuff on everything your organizational pubs
authorize and keep 'em safe till you need 'em.

TM 9-1005-243-12 (Oct 63) w/4 changes is still the bible for your quad ma-
chine gun no big change here from the M6 subsystem.


MOUNT ASSEMBLY -Frayed, loose,

many links are needed from the cartridge
drives to the gun. From the ammo box to
the cartridge drives on the XM16 you need
93 upper LH, 89 lower LH, 85 upper RH and
81 lower RH).









Speaking of chuting-which way
should the open side face, up or down?
Your pubs show both of the front

removed, inspected and cleaned during
every Periodic (100 hours of aircraft

filter element or the preformed packing
is shot, replace it.

chutes with the open side up and both
of the rear chutes with the open side
down.
You'd be smart to keep yours this
way.
But some outfits face the rear chutes
up-especially the one running from
the drive motor to the lower gun. They
say it's easier this way to see and con-
trol the rounds after they pass the drive
motor.
But they also use this system only
when operating in treeless, barren,
sandy country. An up-facing chute like
this is likely to catch sticks and stuff if
you use it in brushy, rice-paddy country.

The solenoid ca-

Never fool around with any of these

place 'em. Every one of 'em's critical
your weapon's feed system and
he mission. F'rinstance, if the cover

Very, very important!

Doublecheck the Part Number on
your intervalometer-is it 11010500
or 11699559?
If it's 11010500-which comes with
XM16 mod kits 1 thru 210-watch
out! Never use the 40-MM mode as a
"safe" position. It's far from safe!
Why? 'Cause if the switch is pushed
forward to the 40-Mode and somebody
presses the trigger on the cyclic stick,
the rockets will go off-just like when
the switch is pushed up or down to 2.75
(Rockets).


COVER 40 WITH
RED TAPE UNTIL
MWO IS APPLIED.

On the other hand, if your inter-
valometer's Part Number is 11699559
(which comes with XM16 mod kits 211
and up), no problem. These have a dif-
ferent switch which will prevent rocket
firing in the 40 Mode.


XM60 PILOT'S SIGHT- That beam splitter (FSN 1270-912-4232 ... 1054-
Dirty, scratched, or cracked 1607) is a sitting duck for guys who're not careful
beam splitter, burned out getting in and out of the chopper. Warn 'er to watch
lamps and damaged wiring, it. This glass is hard to get sometime. Use a chamois
cloth or lens tissue to keep it clean and beware of
leaving fingerprints on it.
Here's hot news: MWO 9-1270-205-30/1 (Jun 66)
provides a new beamsplitter and shield for your XM60
sight to eliminate beamsplitter breakage. Get Support
on the ball. The kits are available.
When iou check the lamp, make sure both filaments
are good. The second filament is sort of back-up sup-
port in case the first one conks out on a mission. Keep
a supph of lamps on hand, too. They come under FSN
6240-635--'978.

This applies to current MW\O's listed in.DA Pam 310-4
and new MWO's as they arrive.

THERE ARE TWO WAYS TO HANDLE RESCINDED MWO'S."

S1. A rescinded MWO is deod. There's no requirement to record, apply or
report on o rescinded MWO
Naturally )ou'll find it listed on the DA 2408-5 for
equipment on which it was applied before it was re-
scinded. Bur if it didn't get applied before rescission,
draw a line through the entry on DA 2408-5 and write
aj'^ "Rescinded by DA Cir ....... dated ... ...- "in columns
Sfg-h and sign in column i. (List the circular that applies.)

2. Or, if the MWO is still needed, ask for instructions from: Commanding
General, U 5. Army Materiel Command, ATTN: AMCMA-R, Washington,
D C 20315
If the instructions say to apply the rescinded MWO
(or get it applied), then you'll record it on DA 2408-5
or DA 2409 and report it on DA 2407 in the same man-
ner as a current MWO.






IF ITS MWO, SAY SO

WORK 'REQ


These are TB's that call for installation of a kit on
your equipment or for a change that's required only for
S a special use of the equipment (F'rinstance, see TB 9-
2300-280-30 Jan 66 ). In these cases you record the TB
on DA 2408-5 or DA 2409 but only at the time it's
applied on the equipment and write "TB" in front
of the number to distinguish it from an MWO.
To report the TB application, you check the Maintenance
Request box in Section I of DA 2407. (In such cases there's no
need to record the TB application on DA 2408-3 or DA 2408-6.
Entry on the DA 2408-5 or DA 2409 takes care of the log
record and DA 2407 reports it to the national agency.)


MWO PRE.PUSL
Since the equipment owner (use) is
responsible for recording all applicable
MWO's on the equipment or compo-
nent DA 2408-5 or DA 2409, you have
to keep a close eye on DA Pam 310-4,
and new pubs bulletins if they're avail-
able.
If you find that a current MWO
applies to your equipment but there's
no record of application of the MWO
on DA 2408-5 or DA 2409, check to
see if the equipment has been modified
by a previous owner (user).
When you find the work has been
done on the equipment to comply with
the MWO, here's the way you record
it on DA 2408-5 or DA 2409:
Enter all MWO identification in col-
umns a-b-c-d-e.


Y-COMPUED-WITH
Then put the date the MWO was
found to be previously complied with
in column f. Leave column g blank un-
less the time required for the applica-
tion is known. Enter in column h the
initials P/C/W (previously complied
with) plus the maintenance organiza-
tion that checked it out. And the man
who checks it out signs in column i.

2407. 6. LOCATION

An MWO found to be previously applied but not recorded on DA Form 2408-5
should be reported on DA Form 2407. Check the MWO box, and enter data called
for in para 3-7.2 of TM 38-750. If data called for in block 20 is unknown, write
"Unk" in the spaces that apply.
(This may duplicate in part a report that's already gone in, but your report
will make sure that the national agency has complete data on these MWO's.)
MAKE SURE THEY APPLY
Before you list that MWO on the DA 2408-5 or DA 2409, though, make sure
it applies to your equipment. Some apply to all items of a series or single stock
number. Others apply only to items with certain serial numbers.
You'll find the word on this in the MWO. So, give the pub the once over with
a sharp eye before you start writing.

ESC COUNTDOWN


Dear Half-Mast, "" '
Item 9 in TM 9-2350-215-ESC refers to DA 2408-8 for the age of the vehicle
in months. But TM 38-750 only calls for "year of manufacture" in block 10 of
DA 2408-8. How do I use this entry to get the age in months?
MSG J. W. T.
Dear Sergeant J. W. T.,
It would be better if block 10 of the DA 2408-8 listed month and year of
manufacture. But there's a way to get the month the equipment was accepted-
if there's a Julian date in block 19.

Note that in Fig 4-12-1 of TM 38-750 the equipment was accepted on 2086. A
reference to a Julian calendar or Appendix I, Table IX, in the TM tells you that
this is March 1962, so March can be considered the month of manufacture.
The equipment data plate also may list the month and year of manufacture or
acceptance.
If you can't get the month of manufacture either from the Julian date of accep-
tance or from the data plate, start your ESC count from 1 July of the year of manu-
facture in block 10 of DA 2408-8.
Make sure you check each ESC TM, tho. On some equipment that's been
overhauled (or rebuilt), the ESC calls for a countdown from the date of depot
overhaul (or rebuild) instead of the date of manufacture.

A quart of oil added now and then gets recorded on DA 2408-1, but all major
lubrications (periodic or to take care of unusual operations or conditions-in-
cluding recoil or other hydraulic oil) go on your equipment lubrication record,
DA 2408-2. And all antifreeze-whether it's a complete winterization or a
small amount added-is recorded on DA 2408-2.
After each lubrication service, make sure you update the entry in block 4 of

'W -- A SUBSTITUTE
Just about everywhere you look with your Nike-Hercules system you'll find
protective covers used with cable connectors and receptacles--when the cable's
not hooked up. At least you should.






CARDBOARD TAPE

And that's where the rub comes in. A cover will take a beating so it can't be
used. Or maybe it'll turn up missing. If you can get a replacement cover ... no
sweat. But not every cover has a twin in the supply system.
If you can't get a replacement cover, do the next best thing. Use some tape in
its place. Page 4.40 of Fed Cat C5970-IL-A (1 Aug 65) lists a roll, -in wide
and 108-ft long, under FSN 5970-840-8454. It's rubber adhesive electrical
insulation tape. Because there's always a chance that the adhesive might pull off
the tape and insulate the contacts, use something like cardboard between them
and the tape.

And that's the time for you to leave
You may be the best violinist at your well enough alone because making the

66) lists the tube for you to requisition, 1430-254-34/12 (10 Dec 63).


WHY FIGHT IT?


If you can't get the blast deflector to
come up snug against the back frame
of your Nike-Hercules mobile launcher,
don't blame the ratchet wrench that's
fastened to the rod for moving the de-
flector back and forth.
Some guys do and then get a long
pipe that'll fit over the end of the
wrench. This gives 'em just the right
amount of leverage-to bust the tip of
the rod.

TIP
No ... if the deflector won't move,
maybe it's sitting on rough ground.
Then the answer is to get a shovel and
smooth it. If that doesn't do it, ask your
support people to look things over.


















Why fight the problem?
And fight it is just what you do when
sou don't remove the plug from the
reservoir for the hydraulic jacks on sour
Nike-Hercules mobile launcher.
That plug-it's cork-is strictly a
shipping plug. Before the people up the
maintenance line send you a new or
repaired jack, they put in the plug to
keep the hydraulic oil in the reservoir.
When the jack is back on the launcher,
and you-haven't removed the plug, you
can go bats trying to lower the jack
to the ground because you're pulling
against a vacuum. With the plug out,
tho, you have air pressure working for
you.
The word on removing the. plug is
in para j(9), on page 210.45 of Change
10 (22 Jul 64) to TM 9-1440-251-10
(27 Jul 59). And when you get a jack,


it could be you'll find a stenciled warn-
ing about removing the plug-on the
side of the reservoir.
Another thing .. whenever a jack
leaves your outfit, fill the hole with a
cork plug or one you might make from
a soft piece of wood. Once again ... the
idea is to keep the hydraulic oil from
spilling out when the jack is in a posi-
tion other than vertical.


GET THE PICTURE?
When it comes to a semiconductor device used in the RF amplifier of
the receiver group in your Nike-Hercules Hipar, there is no substitute.
So when you requisition semiconductor, FSN 5961-736-3728, add in
big letters that you want the one that comes under MA4507R-not
D4075CR.
Using the D4075CR in the RF amplifier can get you big troubles--
like no video. I

HOW TO KEEP A COOL RT-524
Armored vehicles and heat are combining to make life miserable for the RT-

CABLE CORROSION
COLOR ME... CLEAN
That mean corrosive green can make o

So, you better take a look, f'rinstance,
at the RG-type cable from the P-5 plug
to the TB-2 terminal in the AM-914
amplifier-converter's C-band receiver
tuning head.
To get rid of that grizzly green, turn
off power and briskly brush the cable
with a small wire or stiff-bristled brush.
Corrosion can collect on the cable
under the clamp, and it'll eat at the
cable until it shorts out your equipment
or damages tubes. the clamp... or release the clamp and

The RT-698 transceiver's air filter (FSN 4130-060-2966) needs cleaning by
your support at every scheduled 100-hour periodic when used with the ARC-

Of course, operation' in dusty areas calls for filter cleaning' at shorter intervals.
The same goes for the filter (FSN 4130-964-4063) in the Mark-95's 718F-1
receiver-transmitter group.
Guides for removing and cleaning the filter with strong soap in lukewarm
water and rinsing, air-drying and oiling are spelled out in para 54 and 76 in
TM 11-5820-514-12 (Nov 65). Be sure oil is no heavier than SAE 30.
Make sure the excess oil is drained from the filters or it'll be sucked into the
equipment.
A couple extra filters would come in handy for rotation' instead of waiting .
While on this air-cooling jag, remember to keep rags, canvas, personal gear

It's vibration that causes that bbx to shake apart and chop the wiring--and
that ground wire is your only protection.
But to fix, tip support that the rotor and fan gotta be balanced and the burrs
taken off the coupling plate to keep it from shakin' apart. Otherwise the results
could be shockin'.

protective mask can take some moisture
- but, if they ever get soaking wet they
have to be replaced. So, before you go
wading, fording or otherwise sloshing
around in dampness, be sure to wrap
your M17 in its plastic waterproofing
bag.
Just remember, the mask is not to
stay in the bag for more than 24 hours
at one stretch... and never use the plas-
tic bag for storing food, smokes, or
anything else you might chomp on be-
cause it could poison you.


The waterproofing bag (FSN 4240-
377-9401, page 41, SC 4230/40-IL
31 May 66), comes in a small plastic
pouch (approximately 2V2-in by 42-
in), and instructions on its use are
printed on the bag. When you're not
using the bag you can stash it in the
bottom of the carrier, or in the pocket
for the outserts, if you keep the outserts
installed on the mask.






SAM... YOU MADE THE POCKETS TOO SMALL


The M13 decontaminating and reimpregnating kit (FSN 4230-907-4828),
which replaces the MS-series protection and treatment kits, is a real tight fit for
the pocket in your mask carrier. And, some of the pockets may have to grow a
little. For example-
The pocket in most M15 carriers, used with the M17 field protective mask,
take the new kit OK, but in case a pocket is not deep enough you can fix it by
adding 2 snap fasteners which will shorten the flap overlap and lengthen the
pocket.
Here's how:

THE TANK-MASK CARRIERS
On the M13-carriers, for the M14-series and M25-series tank masks, however,
housing the M13 decon and impregnating kit is a bigger chore. The kit pocket

Tryin' to keep track of those guy lines
on the Cap, Flue, Draft, FSN 4520-360-
0098, of your space heater, FSN 4520-
257-4877, is a job. If they get away or
break, order Cord, Cotton, Water and
Mildew Resistant, Type 1, Class 3, 1/V-in
diameter, FSN 4020-233-6555 (3,000-ft
coil). It's listed in Fed Cat C4000-IL-A
(Dec 65).

Paint Sav5e Ignit r
Make sure there's a thin coat of black
paint on the glow tip of your new heater
igniter. Some igniters for Stewart War-
ner gasoline and multifuel personnel
heaters have come thru without this paint
that protects the coil from melting. If you
get an unpainted igniter, either as an
individual item or in a repair kit, dip the
barrel 13/16-in (almost to the threads)
in Paint, Black Enamel, heat resisting,
FSN 8010-297-2013. Any thin, flat black
enamel, tho, is better than nothing. Then
air dry and make sure the vent holes
are open before installing. And remem-
ber, Igniter, FSN 2540-319-5933 (PN
8359919), is strictly for gasoline. Igniter,
FSN 4520-790-8417 (PN 7324355) is
only for multifuel.

You can now order manuals through

operating instructions, and ENG 7, 8,
and 9-5264 for repair parts. Don't ask
for extra copies because there're only
a few available.

Say, out there. If you happened to
get a shiny type H-138/U or H-207/U
handset, lead it to Dullsville soonest. To
kill that slick, bright surface for a nice,
safe, unreflecting kind, rub the handset
gently with a very fine crocus cloth or
something similar-until the thing is
dull. Which is the way it should've come
to you in the first place.
