Sure, they can scoot like nobody's business, but it's how they shoot that makes
them big ground-gainers for Uncle.
This "consolidated" inspection-PM guide will help keep your weapon hitting
paydirt. Use it when pulling your dailies, weeklies, and quarterlies-any time
you're at a halt.
These 2 vehicles have about the same carriage, but from there up they're distant
cousins, at best. So, be on your toes when you roam through these pages that you
don't board the wrong deck by mistake.

alent Full Charge) rating in column g
of its DA Form 2408-4 regularly after
every firing session. If you ever have
any doubt about the tube's service-
ability, get your support guys to give it
a borescope and pullover gage reading
on the M108 and 126E1 cannon.

3. When you pivot the

- Hydraulic leaks; retaining band loose;
bolts and nuts loose; oil level in reser
voir low

Use either the hydraulic power pack sight
gage or dipstick to check oil level. It should
be level to the full after pumping' mark.
However, the accumulator fluid pressure must
be between 925 and 1775 PSI before you
take the reading or you'll get a phony read.

But, for correcting publications on nuclear weapons and conventional ammo
you use DA Form 2415, Ammunition Condition Report, like it says in para
5-6k, Change 2, TM 38-750.
Forms correcting classified pubs, of course, you handle like it says in para

GOT A
HAPPY
TRIGGER?
Hey, Gunner, open the
breechblock of your M40-
Al 106-MM recoilless rifle
a minute and see that it's
got the right trigger on it,
will you?

If the sear end of the
trigger looks like this,
fine Its OK
But if it s been ma
chained to look like this.
gel your armorer to re
place it pionto FSN 1015
300 5390 will fetch the
right one

too

These oldies could cause odd things to happen ... like the rifle firing off when
you close the breech.

XM16E1 SHARPSHOOTERS,
MAKE THIS YOUR SOP...

No sweat, y'say, getting rid of a barrelful of water after fording a stream or
rice paddy? Just point the muzzle down and let it drain, y'say?
Don't bet your life on it! Not with a rifle with a bore as small as the XM16EL's!
Here's why: Surface tension of the water and capillary traction in a small
area like this makes it hard to get water out. If enough stays in there and you
fire off-Bang! There goes another barrel-and maybe a chunk of you.
Water could triple the pressure in the bore when the weapon's fired.
So, make this your own personal SOP every time you drag out of the drink or
fight in a heavy rain in Charleyland. Before you fire that weapon:
i I ,

1. Point the muzzle down and
let the water drain out.

'N

2. Pull the charging handle
back a mite.

3. Press the forward assist to
make sure the round is
seated in the chamber and
the bolt is lodced.

WATER... MORTAR... UGH!

No rhyme or reason for a short round with the M29-series 81-MM mortar-
even in monsoon and rice paddy country-if you remember 2 important things:

1. Keep your ammo dry-espedally the pro-
pellent and ignition system-by keeping 2. Dry out the tube every time it gets doused.

up out of the wet.
KEEP

DRY

Paras 70 and 58b(l) of your TM 9-3064 (Aug 57) w/3 Changes will clue you.

FAITES ATTENTION!

HEY, MISSEWER...
ARE YOUR BATTERIES-
l ERl AS YOU SAY-
CHECKED OUT?
NOT

Oui, never get caught short of CIPEL batteries for your M22 subsystem's
wire-guided missiles. Check the expiration date on every battery on your shelf
and order replacements (FSN 6135-884-7897) at least 4 months before they run
out ... so's they'll have plenty of time to get with you. And, remember, never
use any battery that's passed its expiration date unless it checks out OK (registers
12 to 15 volts) on your GM battery tester.

Dear Windy,
Our TI's have us in a spin over what they call "unauthorized modifications"
to our Seminole (U-8) prop spinners.
First, we ordered a new modified spinner bulkhead, FSN 1610-525-2036,
P/N D 1414-7, which came with a 4-in wide reinforcing band to stop bulkhead
cracking.
But, to put our old spinner, FSN 1610-624-6855, P/N D1367-2, on this new
bulkhead we need to drill holes in the spinner to take care of additional re-
taining screws.
Also, our spinners have a doubler, riveted to the inside around the cut-out
area for the blade shank, to keep the spinner from cracking where the anti-ice
tubes are fastened to it.
Can you square us with our Tl's by citing some authority for these spinner
changes?W2 L. N. W
ICW2 L. N. W.

Dear Mr. L. N. W.,
You won't find any written word
for modifying the D 367-2 spinner
assembly to make it fit the D1414-7
bulkhead but your CO can authorize
the spinner hole drilling. To make this
fix you need to pick up the hole location
on the bulkhead then drill the required
holes in the spinner for the additional
retaining screws.
Instructions for reinforcing blade
cut-outs by adding doublers was in the
old TB AVN 23-5-1 (Mar 60) UR
Digest, on Accessories and Systems.
Some new spinners were also delivered
with doublers, P/N C1411, in them-
so they're authorized.
A new, stronger spinner and bulk-
head assembly, P/N 836-21S, is in the
works ... one that should end this
"tired metal" problem that has always
been with us.

WEAR LIMITS!

MUST BE A
BETTER WAY
TO CHECK!

Dear Windy,
The only way to check for wear on the Raven (OH-23) tail
rotor pitch change link rod end bearings is by hand-checking
the free play.
The trouble with this method is that everybody has a different
idea of how much free play is OK. A more accurate way of
measuring is needed. Tell me, Windy, are there any limits
in the works?
MSG G. H.
Dear Sergeant G. H.,
You must have a crystal ball or something ... the Aviation Command has just
come up with these limits, which will go into TM 55-1520-206-20: side (axial)
play, 0.022-in maximum; end (radial) play, 0.005-in maximum.

Poor lifting and slinging practices can make junk of a cargo truck or van.

Hoisting by the wrong suspension points can buckle a frame badly.

Transportability manuals like TM 55-2320-209-10-1 or TM 55-2320-211-

10-1, cover shipping instructions-but not lifting techniques.

For proper slinging and lifting methods see TB 9-210/1 (Jul 59) and its

Change 1 (Dec 59).

Dear Editor,
Breaking the bead on a tire for a repair job can be quite a chore,
even with a pneumatic tire demounter ... seems like some of those
tires are welded to the wheel
So, we latched on to a 2-in piece of pipe, 30 inches long and welded
a broken pneumatic hammer flat drill to one end. Then we located a
broken I 1-in axle shaft about 36 inches long.
AXLE SHAFT FITS INSIDE PIPE
L- WELDED
PIPE A DRILL
To use the bead breaker you just slip the axle in the pipe and im-
pact around the tire. On a 4-ton, 2 times around the tire will break
the bead, while it will take 3 to 5 trips around on a 2'-ton .
works like a charm.

(Ed Note-Good going. Looks like a
real fine tool to have on hand when
others fail. Just be sure you use a foap
solution on the bead and move the
tool around the tire after each impact
so you don't do any damage.)

TB 3-600 (Aug 66) EIR and Maintenance Digest, has the warm scoop!
If the M13 or M13A1 gas-particulate filter-unit in your tank uses the M3
electric heater (FSN 4240-807-6856) made by Industrial Design Laboratories,
you'd best check the heater's controller assembly for loose electrical receptacles.
If the receptacles are floppy, the controller assembly has to be removed so
the receptacles can be soldered. Otherwise, the tank masks won't be ready to
provide warm air when it's real cold outside. Para 4g of the TB tells you what
to do. M3 heaters made by the Vapor Heater Corporation don't have this problem.

TM says to replace seals when grease is felt behind
is right?
SP4 E. E. H.

Dear Specialist E. E. H.,
Both. Once you understand how the grease seal works on the support
rollers of the M60, M60A1 and M48A2 tanks, you'll see there's no con-
flict between the LO and the -20 TM.
When you're lubing, the spring-loaded seal lets grease pass through
it when the pressure of the grease pushes down the spring. So, if you.
put your hand in the access slot behind the roller and feel the grease
coming through the seal you know that support roller has enough lube.
That's why the LO says, "lubricate until lubricant can be felt at seal
behind roller."
After a little of the excess grease gets thrown out during operation,
the grease pressure will no longer be greater than the spring pressure
so the spring will expand, keeping in the remaining grease.
In other words, the grease seal spring does the same job on the sup-
port rollers that the pressure relief fitting does on the road wheels. That
is why you don't have and don't need a pressure relief fitting on the
support rollers.
You'll find grease behind the seal during lubing and sometimes a
little bit in hot weather or during severe operation.
Other times, if you feel a lot of fresh grease behind a support roller
seal, it means that the seal is not holding and should be replaced-like
the -20 TM says. H /f- t

You supply types can quit worrying because from now on all orders for
Seal, rubber, special shaped section, FSN 5330-807-2874 should be in feet, in-
stead of per each.
This chart shows you in inches how much bulk seal you need for various
uses, where you can find it in TM 9-2300-224-20P/3 (Nov 64), and when there
is an exception to the rule.
To use it all you have to do is add up the total number of inches of the rubber
seal you need, change the figure to feet and order.... Sure beats counting beaches.

If you have an M48A2 tank, an M88 tank recovery vehicle, or any of the
other vehicles with a magneto booster coil, latch on to TB 9-2300-271-20
(May 65). It tells you how to build a simple tester to check out this coil. If
the coil, FSN 2920-565-0785, is OK, you don't need to replace it-which saves
you $20.60.

rHE IRON&
P05ITION!

To make the fuel transfer pump on
your M88 VTR work right you've got
to put the system selector control lever
in the REFUEL position. ... It figures.
But some drivers have been shoving
the lever into the AUXILIARY posi-
tion, which gives emergency power for
the boom and spade but not for refuel-
ing or defueling.
Even when you put the selector lever
in the REFUEL position you're still not
home free.

What happens, crewmen have been
leaving the hoses to the impact wrench
connected while they try to operate the
fuel transfer.
This does not work too good. Even
when you're not using the wrench,
enough oil keeps circulating through it
to lower the pressure so your fuel trans-
fer pump won't operate the way it
oughta.

Simple cure, though:

Now all you have to do for maxi-
mum pumping power of 38 GPM is
slowly move your adjustable flow regu-
lator until the handle points straight

Dear Editor,
We thought you and readers of PS might be able to use the basics on car-:
rying racks we've rigged for transporting (and storing, too, if space permits)
portable radio sets.
We've made three different sized racks to suit the AN/PRC-6, AN/PRC-8 thru
-10, and AN/PRC-25 radio sets.
The handiest arrangement we've found is a four-radio rack.
Naturally, the racks protect the sets while they're in transit to the shop, the
field, or wherever. They've prevented considerable damage... and are extra
valuable for rough terrain transport.
The easy-to-take part of the racks is that all you need are a few old ammo
boxes and a handful of screws. For added protection, a piece of steel packing
case strapping could be put around the outside of the rock. The strapping helps
keep the screws from backing out. STIE STRA
A block of wood 3-in by 6-in screwed or bolted onto two opposing sides
serves as a carrying handle. Of course, the bottom of the box is solid.
Since the size of the scrap lumber used might vary, here are the interior -
measurements needed for each compartment for the various radio sets:

AN/PRC-6 ANIPRC8,1 -10 AN/PRC-25 NA5L.

A RT-524 receiver-transmitter getting a backblast from a 106-MM recoilless

When you have a RT-524 cozied up with a recoilless rifle in, say,an M151A1C

A loudspeaker shutter (FSN 5965-191-6787) for the RT-524 will do the trick.

For hitchhiking a man couldn't want a better friend than a good, active
thumb.
For fiddlin' with a TA-312/PT or TA-43 field telephone a man couldn't
have a worse enemy than said same thumb.
Like so....
Some restless operators, thumbs goin' full blast, wear the rubber insulation
right off the lead-in wires to the handset. Ditto for the insulation at the housing
end.
Lot's of maintenance shops have seen the results, cause that's where the
phones go after the damage.
Another past-time is peeling the insulation from the wires. Same result -
back to the shop. All because of some nervous thumbing.
Speaking of field phones (and switchboards) here's a little caution about
handles on generator hand cranks:
A good habit to get into is to fold the handle back in its slot as soon as you've
finished using it.
Stickin' out, the handle can snag on any of a thousand things and break off.

Trouble is, the bolts holding the battery ground straps to frames or engines
are out of sight most of the time and get overlooked. Dirt and rust get under,
lockwashers fail, and bolts come loose, a power surge hits the radio, and an-
other set's kaput.
Then when rough going comes along, loose connections feed on-and-off cur-
rent. A voltage surge hits a common power pack, and-whammy!
So squint at the ground end of all your ground straps. Unbolt 'em and clean
the surfaces to make metal-to-metal contact on the chassis-or engine. Check

TOE's AND MTOEs

-UI- -

--------------I
Also, in an emergency your outfit can use the fastest means available to get
an OK from DA for additional equipment. Then it has 60 days to send in the
MTOE which includes the equipment requested on an emergency basis.
The big thing with the MTOE is that it's "fathered" in the field by the TOE
user concerned. So, like never before the field has a big hand in setting up its
authorization documents.
Modification of a TOE-who is responsible for the MTOE, when and how
it's made up-is covered in Section V, AR 310-31 (Apr 66), Organization and
Equipment Authorization Tables.

The new TOE format is streamlined,
easier to use and provides loads of
handy info on equipment identification
and use.
The MTOE simply trims or fattens
the basic TOE's allowances to fit the
needs of a specific unit or units.
When a TOE is modified the MTOE
sports the UIC (unit identification code)
of the unit concerned. That's how you'll
quickly spot a published MTOE which
modifies your basic TOE. The MTOE
OK'd for your outfit, of course, will not
affect other units operating under the
same basic TOE.
If DA policy makes changes which
apply to all units operating under a
basic TOE, the TOE will be revised by
a numbered change, not by MTOE.
And, when DA initiates changes
which apply across the board for vari-
ous types of TOE's, the changes will be

published as consolidated TOE changes.
And, as in the past, the consolidated
TOE changes will be numbered in the
300-series.
On your property book page the TOE
allowance goes in the "total allowance"
block and the MTOE allowance goes
in the "current operating allowance"
block.
If your outfit doesn't already have a
TOE sporting the new format, it will
soon--so keep an eye out for it. You
can spot a new one easy enough since
they all have a capital G after the TOE
number. And, also at the bottom of the
cover page you'll find a paragraph that
says:
"This table is published for the pri-
mary purpose of converting the super-
seded TOE to the new format prescribed
by the New Army Authorization Docu-
ments System". (NAADS).

-those things you get "When Author-

cerned (WAB TOC, WAB USACON-
ARC, WAB ARADCOM)-are listed

not included in the TOE's equipment
recap info. In other words, when these
items are needed they'll be authorized
by MTOE

INSTANT SCOOP
The handiest deal in the new TOE
format is the addition of a new section
-Section IV, which is loaded with
equipment identification info, and other
handy info for supply and maintenance
and unit readiness reports and records.
It gives things like:
1. The old LIN's crossed to the new
LIN's.
2. FSN's for all items listed in the
TOE.
3. Commodity command codes. The
codes are explained in para 4b, SB
700-20.
4. Multiple line items showing FSN's
for the authorized makes and models.
5. Equipmenttypeclassification. The
standard A, B, C, LP, N, etc., classifica-
tion codes listed in para 4e, SB 700-20.

IT'S

6. ICP codes (inventory control
points). The supply agencies respon-
sible for the item. And, para 4c, SB
700-20 covers these codes.
7. An asterisk in a column headed
"AR 711-140" tells you an item is re-
portable under AR 711-5.
8. And, an asterisk in a column
headed "ESC" tells you the item takes
TAERS (TM 38-750) records.

LOOKS GOOD... NO?
Yep. Your unit's equipment request-

tions should get easier under NAADS.

SFC J. A.

Dear Sergeant E. J. A.,
Reportable "troop installed" items
which come from your TOE or TA are
accounted for on the property book
page covering your TOE or TA allow-
ance for the item.
A "location" note or the handreceipt

On the other hand, BIIL items which
are issued with a major end item are
considered part of the equipment they
come with and are included in the
equipment's basic FSN; therefore,
they're accounted for on the page cov-
ering the major end item itself.
The page simply takes the note
"w/equipment" in the nomenclature
block. Serial numbers of any weapons

If you've got a Huber-Warco Grader Model 4D with a General Motors

pipe from the air box.
There's a reason for that drip. The engine piston sleeves are now made of
different material so it takes longer for the piston rings to set to the sleeve walls.
After you've run your rig from 300 to 500 hours the oil drip should stop.

When you need a part for your gen-
erator, don't grab just any old generator
parts manual to do your ordering. Make
sure you've got the pub that belongs to
your equipment. Check the latest DA
Pam 310-4 and changes for the TM num-
ber. Most parts are not interchangeable
between different generators so no use
to try 'em.

Taking your whip antenna sections
apart once a day to clean 'em is the
best way going to prevent rust and cor-
rosion. Wipe male and female threads
dry, and get the dirt out.

Tight connections on your MT-1029
