TRANSMISSION OIL LEVEL-If your XTG
411-2A transmission has had MWO 9-
2520-234-30/1 applied, (to modify the
oil level gage) or if its serial number is
1457 or over, you check the oil level
like so... ~
1. Before starting the
engine, make sure the
transmission oil level
is within th, ,py..p ,1j i
range stamped on the
2. Add or drain oil if needed to get it within
Always make ollowonces for the tem-
perature. F'rinstance, if oil is cold it may
take as much as 8 hours to drain back to
the reservoir as against only 3 minutes for
oil at 200 F.
To avoid over-filling, either check
the oil level after operation when the
oil is still hot, or when there's been
enough time for all the cold oil to re-
turn to the reservoir.
ENGINE RESERVOIR The engine reser-
voir, breather and drain can get clogged
with dirt. When this happens the trans-
mission may become pressurized and
too much pressure can blow the filler
cap off the transmission.
When you check over the vehicle,
drain the reservoir and clean out the
breather. If necessary, also clean the
reservoir drain hose by blowing air

COOLING FAN PULLEY -If your M578
was made by Bowen-McLaughlin-York
and has a serial number of 475 or
higher, the cooling fan pulley-retaining
nut may not be on tight enough. You
should have the retaining nut torqued
to 550-575 lb-ft.
RADIATOR FILLING Filling the 2 radi-
ators is a little tricky. Unless you do it
right, air gets trapped in the system and
you can't fill the radiators completely.
The engine will then overheat.
Here's what to do:
2. Add coolant to both radiators, and fill to
top. Do not leave any space. If you sus-
pect a cap is not doing its job, get a new
3. Order it as FSN 2930-690-2701. It's in Ch
1 to your--20P TM.
4. If you think air is trapped in the cooling
system, take off the radiator caps again
and remove the vent plug from the ther-
mostat housing. When coolant flows from
the vent hole, put the vent plug back. Now
refill both radiators and replace the caps.

BRAKE-LEVER CABLE The brake-lever
cable can slip out of the groove of the
equalizing pulley if the cable is too
loose or not adjusted right and one of
the cable retaining clips is bent.
You can stop this by keeping the
cable adjusted and by getting tabs
welded to the clip tangs and bent over
so the brake-lever cable can't get out of
the pulley groove.
BRAKE LEVER When you disconnect
the brake lever you'll find there's no
master spline or V groove to help get it
back on in the same position. Mark the
leverso you can line it up right. Other-
wise, if you get it on too high, the brake
will drag because it'll always be partly
on. If you get it too low, there'll be too
much brake pedal travel before the
brake goes on.

TRANSMISSION BRAKE Your -20 TM
tells you how to adjust the transmission

733-8909 for adjusting the right brake
and wrench FSN 5120-733-8912 for
the left brake. These tools were added

wire are those positioned so the lock- f
wire has to cross over the journal flange. ,
FAN WELL Show-off driving (splash-
ing through mud holes, etc.) will let a
lot of mud and water get into the fan
wells and, in time, clog the radiators. So
hold down on the cowboy stuff! There's
no access plate for cleanout or drain for
the fan well so if you get it full of mud
you've got to clean it out the hard way,

ENGINE SHUTDOWN-Your -10 TM, says to idle the engine at 550-600 RPM
for 5 minutes before shutting it off, but the latest word is that 1000-1200 RPM
for 4-5 minutes is better.
HULL DRAIN VALVES Running your vehicle cross country with the hull-drain
valves open is a sure way to get 'em smashed. So-o-o-o, close all 3 drain valves
before you take off.
SETTING LOCKOUT Back the vehicle
up on the spade before you lock out the
wheels. Reason: If the roadwheels are
locked out before then, they're not
supporting the load. After the driver
sets the lockout switch, he should wait
until the lockout warning light comes
on, which may take 30 or 40 seconds.
The light will not come on until all
lockout cylinders are locked. Put the
lockout on only after the spade is well
When you want to move off the
spade, first turn off your lockout con-
trol and wait until the light goes off
before you move off the spade.
IMPACT WRENCH The impact wrench
FSN 5130-790-2284 is also found on
the M88 VTR. You should have a
copy of the TM for the wrench, TM 9-
5130-338-15P (Nov 61) but you can't
use Table III, the flow regulator set-
tings, because it applies only to the
AIR FILTERS The 2 air filter pacs are
alike but you install 'em different. On
both of them the lever-like handles go

gasket goes to the front.

SLIP RING ASSEMBLY Replace the 2 lube fittings with square-head plugs if this
has not already been done. This'll discourage anybody from trying to lube 'em
daily as the old (Mar 63) LO called for. The slip ring bearings should be lightly
lubed every Q Service.
TOW STARTING If you have to tow
start, put the towed vehicle in 2nd gear MAKE SURE YOU'RE
IN 2ND GEARI
before you start to tow and leave it IN 2ND GEAR
there while you tow the vehicle for-
ward. If the engine does not start when
you reach a speed of 6-8 MPH, check
for something else wrong.
Never try to tow-start an M107 with an M578, because when the M107
starts it may lunge forward and ram its gun tube into the rear of the M578.
TOWING DISABLED VEHICLE You can tow a disabled vehicle for a short distance
(less than a quarter mile) like so .. .
1. Puttowedvehicle shift 2. Do not go over 10 I
in N (neutral) position. MPH ahead or 5 MPH
in reverse. 5
When turning with a towed vehicle, make wide turns to keep from damag-
ing the tow bar or bumping the vehicles together. P-
IF YOU TOW MORE THAN 1/4 MILE
FIRST 1. Take off the drive nut and retainer.
DISCONNECT 2. Disconnect both final drive shafts.
FINAL 3. Put the output drive retainer UNDER the NUT and put the nut on the transmission to
DRIVES keep the spline from re-engaging and damaging the spline threads.
CAREFUL: When the final drives are disconnected, you can't brake or steer the
towed vehicle, so you need to use a tow bar, not tow cables.
The M107 must be towed backward when you are towing it with an M578,
because a standard tow bar is not long enough to let the gun tube of the M107
clear the back of the M578 when the gun is in the travel position.
When you need warning lights on a towed or disabled vehicle, use portable
flasher light, FSN 6220-796-2657.
LOCKOUT CYLINDERS The allen plugs on the (
locking rings of the 8 lockout cylinders some-

BODY & FENDER REPAIR
No use to look for an SM on the body and fender repair tool kit, FSN 5180-
754-0643. SM 9-4-5180-J10-7 was rescinded by SM 9-4-5180-A60 which was
rescinded by DA Circular 310-29 (Mar 65). The only place you'll find that kit
listed is in the Fed Cat C5180-IL-A or one of its changes.
LANDING LEG LUBE
Down ... w-a-a-a-y down ... all the way down.
Yep, you gotta crank those landing legs all the way down when your M127
or other G750-series 12-ton semitrailer gets its regular dose of lube.
Like you see in both LO 9-2330-207-
12 (May 63) and the lube chart in TM
9-2330-207-14 (Jun 61), the landing-
gear-support legs are lubed with OE 30.
But you have to have the legs extended
all the way down so the oil will run into
S r t the reservoir in the bottom section of
L V leg.
PuT I Il PINr Each leg gets 1 pint of OE 30. Give
OF IE A 10- the oil about 15 minutes to get down
I't'tI iinto the reservoir before you crank the
I, l legs back up.
This poop will be showing up in a
TM change or revision.
S NO Q'S FOR WHEELS
That's right- no quarterly preventive maintenance services for tactical wheeled
vehicles. This was the word in DA Cir 750-10 (Apr 63). If your truck or trailer
TM calls for a Q service, you still pull the same service but as a semiannual(S
service) instead of a quarterly. Until your TM picks it up, the word in DA Cir
750-10 (Apr 63) is still good. Make a note for yourself.
What you don't know can hurt you like loose U-bolts on vehicle springs.
When U-bolt nuts get the right torque, they shouldn't loosen up but some-
times they do. You drivers should check 'em out about once a week. Report any
loose ones you find on your 2404 inspection form.
Your mechanic will follow up by .- ;.

If you find metal chips or shavings in the en-
gine oil of your M113A1 carrier, turn the entire
vehicle in to support right away. Reason: poor
oil distribution in the engine caused by the metal
would affect wearing surfaces. Even if you could
get all the metal out, continued operation could
damage the engine still more.

NEVER MIND THE HUMIDITY...
IT'S THE COTTONPICKIN' HEAT!
MN T H_- L
Your M48A3 tank will lose its cool if it gets overheated.
Too many M48A3 engines and transmissions are conking out because there's
not enough air circulating around them to beat the heat.
Here're 4 things you can do to improve the air circulation:
Clogged filters in air cleaners and oil and fuel lines can make the engine and
transmission run hotter than they should.
Drag out your trusty TM 9-2350-224-20 (Jan 66) with its 3 changes, and
service these filters like it says.
Take care of these things and you'll keep your cool and so will your M48A3

plain sight on pages 2.152 and 2-IH, TMN 9-2350-215-10 (Feb 65). And that
means no changes in the way to do it.
~- BOLT BACK I
F'rinstance ... the TM tells you to make sure the bolt assembly's forward -
in battery before you load the ammo. That way the feed lever inside the cover
will fit into the groove of the feed cam on the feed and ejector assembly when
you close the cover.
If the bolt's to the rear and then you do everything you're supposed to do,
you're asking for trouble 'cause the feed lever and cam don't mate. That means
bent or chipped ejector prongs.

Buffering the evacuator case with a block of wood helps dodge such disaster,
but only use it when taking the case off not in putting it back. If it won't go
back, find out why no substituting a hammer for correct fit.

M60A1 TANK BRAKE TIP
When you install slave cylinders in
your M60A1 tank, do it the easy way.
Before removing the slave cylinders,
make sure the parking brakes are in
the locked position. With the parking
brake locked, you're not so likely to
damage the inserts and spring inside the
cylinder housing during replacement.
The rest of the word is spelled out in
Fig 2.141 in TM 9-2350-215-20 (Feb

watching what he was doing.
That's like the guy who's pulling the
cover off the TT-76() teletypewriter

'Cause an Army-type paying a no-
never-mind winds up disconnecting
cables in the oddest places like in
the middle or just back of the plug, and
lops 'em right out.
Take the copy light cable ...
Keep in mind when you're removing
the TT cover, open the lid first, dis-
connect the P12 plug from the J12 jack
on the right-hand side of the power
supply and terminal unit .. then take
off the cover.
I DISCONNECT IT FIRST!
Same goes for the P6 plug for the
transmitter-distributor that's connected
to the J6 jack in the TT-76's base. Just
make sure the plug's free before pulling
out the component.
AND THIS ONE, TOO! 0 0..
Sure, these tiny plugs are tough, but
the cable won't take a lot of rough
tuggin'. So, remember to give 'em the
gentle disconnect treatment.
Before cutting' loose with the muffled cussin' against your AN/PVS-1 or AN/
PVS-2 individual weapons mounted night vision sight, take a look at the adapter
'Cause a mismounted adapter can shift and throw you off anytime.
Be sure the adapter assembly is flat against the top of the receiver on your
rifle, and shove 'er all the way forward.
Team this up with the steps for installing on Page 21 of TM 11-1090-268-13
(Jan67) for the AN/PVS-1, or Page 22 of TM 11-5855-203-13 (Apr 67) for the
AN/PVS-2, and you'll be in the class with William Tell.
PAMPER A PIPSY-4
Hey, hold it, freight man in an air call-carry wagon. When you're bringing
in an AN/PPS-4() radar set for troops on the firing line, don't swing that
chopper low and kick the set out of the chariot. If you can't set the chopper
down, lower the Pipsy-4 to the ground by rope. Bumping it out can really make
that Silent Sentry silent.
THRiOUGH THE STRAP
The way they're being used up you'd think they were going out of style--
the connector adapter, FSN 5935-073-5331, that's part of the devon follow-up
cable for your Hawk AN/MSM-43 organizational maintenance shop equipment.
Seems that the adapter pins get busted when the cable is connected to the
missile follow-up jack. This will happen when the cable is hooked up from the
bottom of the bird. This way the weight of the cable pulls on the adapter, put-
ting pressure on the pins.
The odds are you won't have broken adapter pins if connect the cable
the right way-by first running it through the hooks on the missile umbilical

That's where you
That's where your safety and arming device, initiator and documents should
be in the cover for your Hawk missile container.
And those d9ors want to be closed good and tight to keep out water, stuff

It's up to you to keep the doors closed, but if their rubber seals are on wrong,
shot or missing, ask your support unit for help.

Maybe it's happened to you.
Your Hawk launcher goes into standby when you put it in remote ... you get
bit by stray current when you touch bare metal... or the launcher acts like it has
a mind of its own when you turn the elevation and azimuth handwheels on the
launcher control unit.
o Chances are the LCU has a snootful of moisture.
Once you get rid of the stuff, you can help to keep it out by making sure the
pressure equalizer valve's closed except when the LCU is moved by air ... keep-
ing the lid closed when you can, during bad weather ... and being sure the lid
is in good shape and fits tight.
Also-and here you'll need your support unit's help-replaced parts should
have waterproof gaskets or seals. The control panel assembly should be sealed
whenever it's taken out and then put back in the LCU.

A CLEAN SWEEP
It's been happening at Hawk outfits-- dirt and dust getting on the
gears in the azimuth and elevation comparators for the AN/TPQ-21
simulator station. And the way those gears mesh, it doesn't take much
wear to get gear slop and backlash.
How does the dirt and stuff get at the gears?
When you open the comparator drawers to make an adjustment
and then forget to close them when you're done. That's one way.
Those drawers want to be closed, especially when the equipment's

Sure. it means some extra steps, but it's one way to stop trouble
before it starts in your Hawk AN/MPQ-39 high powered illuminator
That is, to go from radiate to standby and then to off the way it
says in table 6 of TM 9-1430-511-12/1 (Jan 63), including Ch 3.
If you shut down the radar without first going into standby, you
can wind up with burned radiate interlock switch contacts. Burned
contacts throw the 5-minute time out of commission. And that means
you won't be able to radiate or maybe not get the radar up to operat-

The best yet!
That's the word on the new repair parts
and special tool lists (RP&STL's).
Everything is clear and simple and neatly
laid out for maintenance and supply men.
Best of all, they list allowances in whole
numbers. You'll use a formula only when
you're figuring up your initial allowances for
over 100 pieces of equipment.
"As required" items are flagged with an
asterisk, as they have been in the past. The
mandatory stockage items are coded with a
+. This + is brand new so you may not see
it in the parts manual for a while.
** *** ACROSS-THE-BOARD ** *** *
The new format will apply when a RP&STL is published as a -P manual (-12P,
-20P, -14P, -15P, -24P, -25P) and also when it's included in a maintenance TM.
It also applies to the BIIL in the operator's manual.
The consolidated type repair parts manual-like the tank-automotive equip-
ment manual (TM 9-2300-223-20P) remains on the scene, as is.

Some of the very first manuals published under the new format may not have
all the fine features you'll find in the latest RP&STL's. That's 'cause some TM's
had to go to press before all the latest improvements had jelled. But, eventually,
all new repair parts manuals will sport the new, easy-to-use format.
The eir) latest RP&STL's use a unit-of-measure (U/M
column in place of the unit-of-issue column used in older
manuals, and early type RP&STL's. The "unit of measure" --
is the unit you normally use when you do a repair job. The
U/M gives the amount or quantity (each, pair, pound, ,
gallon, foot, ounce, can, etc.) your allowance is based on.
That is, a RP&STL quotes the U/M's you're authorized. And for the unit
of issue info you need for your DA Form 2765, you go to the supply publica-
tions (SM's, SC's, ML's, etc.). Then all you have to do is order the lowest
number of units of issue that'll provide the U/M's you're authorized.
In all cases, of course, it's a good idea to check for any unit of issue info
you may have on an item from your supply support outfit.
i* QQ^ -^ i^ i-5* 0D- OTHER CHANGES i*^ a `ir *- a T
In the latest RP&STL's you have fewer columns in the various sections. And,
in RP&STL's that cover all levels of maintenance (like a -25P or a -15P TM),
the separate sections for organizational level fall in a different sequence, so
they're not numbered the same as they are in organizational level RP&STL's.
And, when changes or revisions are published on a RP&STL you'll have
action codes to the left to tell you what's been updated. The codes, used
along with the FSN or nomenclature info, are:

the RP&ST. made in the item's description.
TO KNOW YOUR RP & STi
When you crack a RP&STL for the first time stop at the "Introduction" sec-
tion and read it carefully before you start thumbing through the manual. The p
section gives you complete info on the manual's format and its use.
If you have any problems or questions on a RP&STL just put in a DA Form
2028, Recommended Changes to DA Publications, or drop PS a line-Connie
and Half-Mast will be standing by to lend a hand.

For all other equipment
the maintenance supervisor
decides which uncorrected
deficiencies (faults) will be
transcribed to DA 2408-14
and approves by signing in
column e of the form.
Even though the decision is up to the maintenance supervisor, it's generally
assumed that there's a need for entering an uncorrected fault on DA 2408-14
only on operable equipment. It's also assumed that when there's a deficiency,
steps usually will be taken immediately to correct it (and record correction on
DA 2408-3) or make out immediately a DA 2407 maintenance request to send
the equipment to support. If this is done, no entry of the fault on DA 2408-
14 is considered necessary. (The entry on DA 2404 plus a status entry on DA
2408-1 -if the equipment has one-will show the equipment has a deficiency.)
With a deficiency, the equipment is-by definition-inoperable (nonopera-
tional). Even if the deficiency status symbol is a circled X, the equipment is
inoperable unless released for continued limited operation by command

So, it's normally assumed that there would be a need to enter only deficien-
cies with a circled X status symbol or less-serious faults on DA 2408-14. In fact,
if limited operation of the equipment is to be authorized, it's considered advis-
able for command to temporarily downgrade an X symbol deficiency to a
circled X deficiency (re-entering it on the next open line of DA 2408-1 and
signing the new entry) before transcribing it to DA 2408-14.

That's the recommended procedure. But, except on aircraft, TM 38-750
doesn't specifically say that any deficiencies (X or circled X) can't be transcribed
to DA 2408-14 even though the equipment remains inoperable as long as
there's an uncorrected X deficiency on the form.
