A guy like you in a fighting outfit
seldom has to worry about a big word
like "logistics." There are several
thousand military and civilian spe-
cialists spread from here to 'on who
do the logistics worrying for you.
But, sometimes it's a good idea for
you to get a little whiff of big things
when they happen in the Army's
logistics business. Now is one of those
times.
Top-level logistics "wheels" have
been working on the supply-mainte-
nance business recently, and they
have come up with some big changes
in the way things are managed. You
may never hear about all of these be-
cause they are being made mainly in
higher-level supply commands. The
changes are aimed at giving you -the
fighting man-the equipment, repair
parts and supplies you need-when
you need them.
Take DA Circular 700-18 (Nov
69), for example. It gives the word
on what supplI outfits, from Wash-
ington all the way out to your own
DS unit, will do to make sure the
items you need are supplied to you
as fast as possible. and with the least
cost to Uncle Sam. j -
une way uns is nemg none is Dy
chopping down the big stacks of
equipment, parts and supplies in sup-
port units and depots, but they'll still
give you quick supply of what you
need by what's called "inventory in
motion." That means direct, non-
stop supply support from the source
back in CONUS to wherever you're
located.
Another way is speeding up han-
dling of requisitions and shipping of
the supplies. That means every sup-
ply outfit will cut to the bone the time
it has your order in the works; also,
fast transmission of supply data over
communications networks is being
made even faster. More shipments
will come by air, like on the new CSA
super-sized jet.
Several special operations are
"Go." and others are in the works.
You mab have heard of "Closed
Loop" and "Fast Fix." There will be
more.
All of this boils down to what
General Abrams called a "Logistics
Offensive" aimed at modernizing
and streamlining the Army's logistics
lo match the modern soldier and his
fighting outfil.
Keep an eye out for more to come.
II's all aimed at giving equipment,
repair parts and supplies to the most
important man in the whole U.S.
Army- YOU.

38-756,TUNE-UP% AND ..
*RK LOAP REPCEI
I
Its name's changed from TAERS to TAMMS.
It's finer-tuned in records-keeping rules; it drops
reporting on some equipment items altogether; and
it makes some needed revisions in forms.
Best of all, it cuts down the equipment user's re-
porting workload.
That sums up to a T (for TAMMS, that is) the
latest edition of The Army Maintenance Management
System, TM 38-750 (30 Dec 69).
OVERALL WRAP-UP
Here's an overall wrap-up of major changes:
DA Form 2408-3, the organizational maintenance
form dropped by DA message and DA Cir 750-32, is
mustered out of service. It's now a dead duck (unless
your CO wants to hang onto filled-in log copies for a
spell).
Five forms are revised and streamlined to do a bet-
ter job. They are DA 2408 (log assembly), DA 2410-
1 (aircraft component movement and condition), DA
2416 (calibration data), DA 2417 (unserviceable or
limited use tag for calibrated items) and DA Label 80
(calibration tag). All these revised forms have new
dates.
5
-l"M M."T12-
All 10 DA forms of the 55-series for
watercraft are deleted from TAMMNS.
Better keep your records, though be-
cause new info is coming down the pike.
When equipment's at support at the
end of a DA Form 2406 report period
(20th/21st day of the report month),
support'll send you a breakdown of
supply-maintenance (NORS/ NORM)
DD Form 314 becomes a mini-work-
horse form in TAMMS. Besides the PM
schedule for equipment, you'll carry
there the equipment's organizational
and support record of NORS/NORMI
time, including that for commercial ve-
hicles.
DD 314
IS STILL NOT USED
FOR AIRC RAFT AND
IS NO LONGER
REQUIRED FOR
PARACHUTE PM.
The accumulative DA 2406 materiel
readiness report dates are alined with
dates for unit readiness reports (AR
220-1 and AR 135-8). Dates are the
20th of March, June, September and
December. (Note also interim monthly
interval for items marked b\ asterisk in
the TM's Appendix "C").
6
TRANSCRIBING TRIM
Transcribing of maintenance actions from DA Form 2404 to other forms is
limited to organizational maintenance actions that require reports, and actions
that require support maintenance requests.
As authorized by DA message and DA Cir 750-32, both organizational and
support units use DA 2407 for required reports on maintenance actions.
Except for aircraft and selected mis- --...
sile items, reportable organizational 62=
maintenance actions are cut back to-_
application of MWO's, replacement of _
tactical and combat vehicle engines/
power packs, counting devices (odom-
eters, hourmeters, tachographs and -
such) combat vehicle tracks, replace-
ment of gun or howitzer tubes (40MM
and above), and filing of equipment
warranty claims where these apply. ACCURA
(Warranty claims are an added use of 15 THE KEY

too.) Don't forget to use the EIR (DA WITH FORMS.
Form 2407).to tell designers about your
defective gear.
ADDED DATA FOR GUNS
--' "* DA Form 2408-4 gets additional data
S on weapon identity, breech rings and
retubings needed to comply with TM
9-1000-202-35 and TB 750-231.
For the same purpose, recording of
-- gun and howitzer tubes and breech
mechanisms plus changes of these com-
ponents, with equivalent full charge
(EFC) rounds data, is required on DA
2408-10.
----
DOUBLE-DUTY FORM
Top job for DA Form 2408-7 still is reporting equipment transfers, gains and
losses, bur it'll also be used to report usage data (hours, miles and rounds) for
tanks and combat and tactical vehicles as designated in the TM's Appendix C.
These reports are made quarterly (1 Feb, I May, I Aug and I Nov) for tanks and
combat vehicles; and semiannually (1 May and I Nov) for tactical vehicles.
7* >
Options are provided on use of DA Form 2408-1 at service schools and training
centers (for equipment not reportable on DA 2406) and at administrative motor
pools operated under AR 58-1 where equipment is dispatched by DA 2400. At
motor pools this applies to both daily and monthly DA 2408-1, if another means
is used to record info normally entered on the monthly.
NUMBERS DROP
Except for commercial vehicles, the... -
old TAERS line numbers formerly used
in TM 38-750 have been dropped. The
equipment category codes (ECC, from --
Appendix C) plus line item numbers
from SB 700-20 are used as a substitute
for the former TM category line num-
bers on DA 2406. On other records and
reports, line number blocks may be left
blank (it's optional with your CO).
The listing of equipment which requires log records (para 4-21) is set up by
ECC, except for commercial vehicles, which retain the 340000-series line numbers.
Appendixes B, C, D and E-on forms required to be submitted-are set up in
ECC sequence (again with the exception of commercial vehicles, which are in the
6-digit line number sequence).
,. MAILING GUIDE
Appendix B, mailing addresses for forms, has an
added section for EIR's on items not otherwise re-
portable. Addresses for these items can be identified
Sby Federal stock classification (FSC)-the 4 left-hand
digits of the item's FSN.
T ARMY METROLOGY All calibration data goes direct to US Army
AND CALIBRATION Metrology and Calibration Center.
CENTER The requirement for log records and data collec-
Stion on medical equipment is eliminated--except
for MWO records and reports.
Equipment failure codes, parts source codes (Ap-
pendix A), and calibration codes (Chap 6) are re-
duced. In Appendix A, equipment category codes
(ECC) are added as Table 20.
.10..
In addition to guidelines for aircraft
entries, para 4-13 limits entry of faults
on DA 2408-14 for other equipment to
those with a circled status symbol
or one that's less serious. (Only red dash
and red slash symbols for aircraft are
allowed on this form.)
Units with tools and equipment that
require calibration (TB 750-236) are
required to submit initial DA 2416's
(Master Record Card) to their calibra-
tion support for all items that get peri-
odic calibration. After that these forms
n are kept for scheduling and updating by
C -- the calibration support unit, if auto-
matic data service is available. (If man-
ual processing is necessary, the schedule
may be on DA 2416 or DD 314.)
CALIBRATION RECEIPT
After initial submission of DA 2416, the user may need DA 2416 as a receipt
for an item turned in for calibration. But DA 2402 may be used as a receipt-
instead of 2416.
In addition, using units are required to submit DA Form 2416's to a new call-
bration support unit upon relocation or inactivation, or when new items that re-
quire calibration are received or those on hand are turned in.
DA Form 2407 is still required for calibrated tools and equipment but only
to request maintenance repair actions and submit EIR's-not to request
calibration. 1
CHECK CHANGES
Cast a sharp eye on those equipment lists in para 4-21 and the appendixes.

- Pamper it with PM and TLC. Treat
it right and your AN/PPS-5 radar set
may ger to liking you so much that it
will let no Charlie by it.
Here's the nirrtty-gritty of %our PM
psychology:
1. Pipsy-5 gears are plated and need
no lube, graphite or such.
Lubing 'em can pack 'em up or make
the kind of mess that can send your set
all the way back to depot for repair.
DON'T

2. Caution is the word if your set still
has the CX-8666/PPS-5 remote cable.
The male plug on theCX-8666 will
mate with the male receptacle on the
C-4610 control indicator if you acci-

dentally reverse the cable ends. Then,
when you push the cable connector into
place, the pins in the plug and recepta-
cle can be bent or broken.
l.2a5f. sE mlW. we 1W
So, look before you connect. The
male end of the connector goes to the
remote cable receptacle on the RT-692
receiver-transmitter.
You don't have the problem with the
replacement, the CX-12004. With each
cable, though, you gotta remember to
insert the male plug straight in. No
bending or wiggling... otherwise, bent
pins.
3. If you can't quite make your azi-
muth checks per paras 2-56 and 2-57
of Ch 2 to TM 11-5840-298-12, forget
about bringing in the R1703 azimuth
sweep potentiometer ("pot") by adjust-
ing it with a pair of needlenose.
You'd be reaching toward a repair
job.
And, using an ohmmeter on the
R1703 pot can damage the pot. Check-
ing it out is a job for your support...
which does it with a resistance bridge.
Besides, in addition to burning out
the potentiometer, chances are great
that you'll also damage the ohmmeter.

Let the solvent set a minute or so to

the area with a cloth or sponge to loosen

Wipe the area thoroughly dry with a

Keep the dry cleaning solvent off
transparent plastics because it'll damage
the plastic.
To guard against skin corrosion, es-
pecially in salt water areas, wind up the
dry cleaning process by using solvent to
spot-clean the exterior of your bird.

While you're at it, have a look-see at the fuel quantity decal. Birds with serial
numbers before G7-15786 had a bogus decal reading "247 gallons." The decal
should read "270 gallons." If not, make a note in the log book to get it changed,
pronto.
Never pressure spray your bird. You
want a continuous flow of compound or NEVER SPRAY HERE -
water rinse at no more than about 5 PSI. CORRODES IRCUIT BOARD.
A pressure spray directed at the ac-
cess door for the impedance matching
network, for example, can really foul
up the works.
Moisture forced inside the cover will
corrode the contact points. Some of the
radios will be knocked out, for real.
The contacts are coated so you don't clean 'em; if you do, you'll remove the
protective coating. The only maintenance action is to change a corroded plastic
card.
For the best cleaning results do one section at a time. Leave the compound on the
skin a few minutes because dirt tends to harden on exterior surfaces. Rub dirty
areas with a brush to loosen grime.

Don't forget the weapons subsystem pods-they also get the oceann treat-

So much for exterior cleaning to protect the paint and head off corrosion. Your

Beauty is skin deep. The real savings
of maintenance down-time and elbow
grease comes by keeping the innards of
your bird clean.
Clean parts wear longer. Take the
tail rotor control cables, chain and
sprocket. The rotors drive dirt under
the driveshaft covers. Any grease on
these parts will hold the dust. The grit
formed can eat on those cables and cause
early replacement.
So, keep those tail rotor controls
bone-dry. Latch onto some methyl-
ethyl-ketone, TT-M261. FSN 6810-281-
2785 will get you a 1-gal can.
Careful, now! That stuff is strong
and will take the hair off your chest, not
to mention the paint off your bird. It'll
even melt plastic.
Use gloves and put the solvent on
with a rag, making sure you use it only
on the cables and chain. It does a terrific
job on bare metal.

You know what that means? A lot of cain raised when the pilot sprays roc-
kets everywhere but on target .. another boresighting chore.
Walk on the forward part of the wing which has the walkway compound on
it, not the trailing edge.
NEVER SPRAY SEALS, SERVOS
Be mighty careful where you direct any cleaning compound spray and when
rinsing the compound off. Otherwise, you could force compound and water past
seals and into un-potted electrical connections to foul up the works.
It's true! Some early birds still have some un-potted cannon plugs. It's a good
idea to go over your charge at the first opportunity to see that the plugs are potted.
FSN 6850-880-7616 will get you an 8-oz tube of insulating compound, MIL-S-
8660, electrical, paste form. Crewchiefs or radio repairmen can pack it in the
plugs like putty-to keep moisture out.

door will chafe the transparent plastic.
USE DRYCLEANING SOLVENT
In areas where you can't spray, such as the electrical compartment, use a clean
rag moistened with drycleaning solvent.
Use dry air and wipe with a clean WIPE WIRING...
cloth where you have electrical wires or
where a compound spray might pene-
trate seals. Use drycleaning solvent on
the engine to get rid of oil, grease and
dirt.
It's OK to spray compound on the en-
gine deck and other areas relatively free
of electrical connections.
NOT TOO MUCH
PRESSURE
Make sure the water drains. If neces-
sary, use a rag to dry up trapped water.
Then you can button up your baby.
Before you wind up the cleaning
chore and head for your hooch give the
cockpit a good going over.
Odds are you don't have a vacuum
cleaner, so latch on to a sash brush. A
paint brush will also do the job. Sweep
the dirt up and out.
Dirty transparent plastic can drive a
pilot to distraction, so, make with a
suitable polish. Plastic polish, FSN
7930-634-5340, does a first-rate job on
taking dirt,oil and grease off the canopy.
Yessir-e-e-e, a cleaning is just about
the best preventive maintenance you KEEP 'EM
can pull on your bird. Schedule one, (LEAN
soon.
STEAM CLEANING? CAREFUL, NOW!
When a bird needs a paint job and your unit has a steam cleaner, never direct
the pressure spray toward viral parts. The compound will be trapped behind
seals and corrode components-you'll do more harm than good!
Spray the compound at 180 PSI maximum pressure, keeping it off propeller
blades, hub seals, generators, starters, switches, relays, control actuators, bear-
ings, rubber door seals, tires just about everything but the bird's skin.
Rinse the compound off cleaned areas with plenty of water to bead-off skin
corrosion.
Cleaning compound, MIL-C-22542, will give good results. FSN 6850-753-4998
will get you a 55-gal drum; FSN 6850-753-5000, a 5-gal drum. Mix 1 to 1-1/2
gallons of the fuid with 60 gallons of water. Heat the mixture to 165-degrees F.

Dear Specialist S. T.,
On the gasoline trucks (the horizon-
tal pipe system), you look for excessive
vibration first. Check the timing and the
ignition. Check for loose engine mounts.
Then, make sure your pipe mounting
brackets are flexible. They'll crack if

too rigid. And whenever a nut works
loose or it's removed, replace it with a
new one. Old ones just won't hold.
If problems still poke you, requisi-
tion special self-locking nuts. For the
7/16-in studs, you use FSN 5310-057-
7080 and for the 3/8-in screws, it's FSN
5310-950-0039.
The multifuel vertical exhausts with
the 465-1 engine can be secured at the
turbocharger by using 3 lockplates,
FSN 5340-909-2503, on the adapter
capscrews. Torque the capscrews 23 to
27 lbs-ft. Then, bend tabs over heads of
capscrews.

DRAG LINKS BUGGED?
You can't keep the bugs away from the 5-ton truck steering linkage with a
magic spray. You need down-to-earth PM.
You've got lots of small parts in the drag links, the relay lever and the bracket.
If any one goes kaput, you could be in a pinch, but fast.
Your truck can wander and weave. The linkage can wear, loosen even snap.
You'd sure be looking for answers then.
Is it a frozen bushing? A busted seal?
Maybe a cracked ball seat? Or spring action quit?
Hold one-and think.
You can head off breakdown if you cop the troubles before they begin.
Here's how it's done with the drag links:
With this plan and TM 9-2320-211-20 (Mar 63), you'll never get the wrong

RUST IN NICE
THE WHEEL DUNE
CYLINDERS. BUGGY
Rust can ruin you if water gets into
the brake fluid of your M151 1/4-ton
truck.
How could water get in there?
Just point to the master cylinder
filler cap, and you'll hit the cause right
on the button.
Before you touch the cap, take a good
look at it-as it sits under the hood.
If the cap's 2 vent holes are straight
up and down, you're building up rust
in your wheel cylinders, master cylinder
and brake lines.
Here's what happens when it rains;
1. Water drips off hood edge onto
cap.
2. Cap shoulder forms backwash
near top vent hole.
3. Water flows steadily into
master cylinder.
Now, it's time to take action. Plug
the vents with MIL-S-45180, Type 1
Sealing Compound FSN 8030-247-
2525 and drill a new 5/64-in vent hole
down through the center of the cap.
That'll do the trick, like it says in the
EIR Digest, TB 750-981-3 (Jul 68).
But, be sure you don't goof up the
works by tightening the cap too much.
This could've been the problem in the
first place.

I on the aluminum receiver
1 is there for 2 reasons.
First, it cuts down light reflection during patrolling actions. Second, it pro-
tects the metal from exfoliation.
Exfoliation? That's right! It just means bare aluminum starts flaking off once
that protective rough stuff's gone. Because that rough finish is actually a hard coat
anodized on to the receiver.
If you use your rifle bore cleaner (CR) and LSA regularly, this protection
should last for a long, long time. But once it goes, and the shiny aluminum shows
through,you need to turn over your weapon to the unit armorer for quick main-
tenance action on the bare aluminum parts.
ARMORERS CAN REPAIR IT ,,
If you get your rifle to your armorer before exfoliation
starts, all he has to do is paint the shiny areas.
If you don't get there in time, your armorer has the proper
tools to stop exfoliation (or flaking) action.
That means you armorers can smooth off the corroded area 1
with crocus cloth. Then wash off the bare metal with dryclean-
ing solvent. Recoat the bare aluminum with solid film lubri-
cant and let the parts dry for 12 to 16 hours in a well venti-
lated area before you reassemble the weapon. 7 3
4-O IMO.RE
CAREFUL WITH THAT LUBRICANT
If any of this lubricant film spatters
inside the receiver parts, wash it off with
drycleaning solvent. The inside toler-
ances for the receiver parts are too tight
to allow any film to build up in there. /
This will definitely interfere with the
weapon's operation.
These rules apply to the upper re-
ceiver, lower receiver and lower re-
ceiver extension depending on how
much of the weapon's aluminum needs
cleaning and recoating at one time. Be
sure you check all 3 parts anytime you
have to fix one of them. And wire brush-
ing is always no-go on aluminum
weapon components.
SUPPLY STUFF
The supply side of this maintenance situation requires knowing a few FSN's:
By the way! Don't wet your patch with bore cleaner until you're sure of what
you've got.
If your cleaner doesn't show MIL-C-372 some place, toss it back.
Could be another breed of cleaning compound which both your fingers and
your weapon wouldn't appreciate contacting... such as this MIL-C-11090 variety.
That's a degreasing solvent which has nothing to do with cleaning bores.

So, you be smart, huh? Get your TM's procedures down pat and follow the
script every time, like so:
This is for you guys with M108 or
M109 self-propelled artillery.
Your 8V71T Detroit diesel engine
can burn up if you don't know what to
do when the master warning light
comes on.
So here's what to do when you get
the warning light:
1. Put the shift lever in neutral (N) and set
engine speed to fast idle (1000 to 1200
RPM). I
THERE'S THE WARNING...
SO WOTTA
YA' DO?
2. Check the engine and transmission oil
pressure gages. The engine should read
between 30-50 PSI and the transmission
between 10-13 PSI. If either reading is low,
return engine to idle, stop the engine by
pulling the fuel shut-off control handle
and find out why the pressure is low. Get
help from your unit motor pool if you
need to.
OIL PRESSURE
3. If the oil pressure is OK, check the tem-
perature gages. Engine coolant tempera-
ture should not read above 230 degrees
and transmission oil temperature not over
WATER TEMP
300 degrees. If either gage reads higher,
run your engine at a fast idle (1000 to
1200 RPM) until the reading goes down to
170-185 degrees for the engine coolant
temperature and 220 degrees for the
transmission oil temp.
If it takes more than 5 minutes to get the
temperatures down, stop the engine and find
out why.
When you have to add water to your radia-
tor you never do it with the engine hot. Let
'er cool down to 170 to 185 degrees at least.
Follow the instructions in your operator's
manual for adding water to the radiator.
After adding coolant, put the radiator cap
back on tight and run the engine at least
5 minutes at 1000 RPM. Check the coolant
level again and add some if necessary.
On late M109's, the cooling system pres-
sure is vented through a pressure relief
valve, FSN 2930-475-1506 (P/N 10922327).
With early model M108 or M109 howitzers
you have to open the petcocks when adding
coolant so you can purge air trapped in the
cooling system .s
The radiator cap, FSN 2930-979-5592 (P/N
10882098), on the M108 and M109 how-
itzers, has no vent. Make sure you have the
correct seal in place, and that the cap is firmly
seated and sealed after you add coolant.
You'll find the correct radiator cap
seal in parts manual TM 9-2350-217-
25P/1 (Jan 69) on page 327. It is either
Item 11 or Item 12 depending on your
vehicle serial number.

A charge that fails to fire is a possible clue to a fouled breech mechanism on

But why wait that long to find out something's wrong when regular reaming
and cleaning of the narrow passages in your breech mechanism could have kept
your piece from fouling in the first place.
Some powder residue works its way past the obturating parts and through the

No, you do not ... unless you'e got
some good reason to paant a ner rear

The same idea goes for shutdown. You idle down for 5 minutes.
It takes that long for your turbo to calm do" n, and it can't get oil unless your
crankcase pump is going.

B. Don't think your LO is incomplete just because it doesn't mention a grease
fitting for your water pump. That pump is factory lubed, and gets greased again
only by support maintenance or higher. But if drag develops and loosens your
drive belts, do holler for support-it'll save your bearings.
C. Before you move out every morning, check those
stiffening rods. If they're not tight and straight, they can
bend your route just enough to land you in Chips' Creek
- you literally can't steer where you want to. A check on I
your pan cylinder rod (protective-cover it if you can)
won't hurt right at that time either.. and might keep
you from hurting later.

Use 'em before every run. A 40" grade- loaded- is no
place for aches in the brakes. They're valve, drain, code
(06853), P/N 277120, and you can use emergency sub-
stitutes if there's no other choice.
E. Make sure your rain cap-your "butterfly" on top of
your exhaust-is healthy and working, even if there's not a
cloud in sight. If that butterfly gets sick, whichever thing
happens is bad- if it sticks shut, the exhaust blows soot back
into your air cleaner and ruins it (which ruins your engine in
a half hour to maybe 3 hours). If it sticks open, rain gets in

You can just note "Bal Brought Fwd" across columns a
and b of the new card, date the entry, and attach the new
I card to the filled card.
Keep the filled card until its info is no longer current for your quarterly re-
views, and then toss it out.
ROD card info is current for 12 months (4 review periods) after an item first
goes on your PLL. After the first 12 months all you need is demand info for the
current 180 days (2 review periods).
You can continue to use the old title
insert with a new card-just correct its
info as needed. Anytime you have to re-
make a title insert, of course, you must
transfer the date the item first went on
your PLL, to the new insert. ---- ----- --- --

VA4 Form 17 Change
You won't get the changes with the
basic pub automatically when you fill
out that DA Form 17. You have to list on
your 17 exactly what you want-or you
won't get it. For example, list "TM 9-
2320-238-20"(when you need only the
basic); "TM 9-2320-238-20 and changes"
(if you want the basic and all changes);
"TM 9-2320-238-20, C3" (when you
need only the last change). If you need
C2 and C3, you list "TM 9-2320-238-20,
C2 and C3". Remember, if you want the
basic publication, be sure to put that
word "and" between the publication
number and the changes you need.
