NEW DIPSTICK -
Late production M35Al's have a new dip stick with revised markings ".
which provide for additional oil capacity and two-quart increment marks
to help you estimate how much to add. The new dip stick has the same
number as the old stick (Part No. 10912158, FSN 6680-887-1334).
Before starting the engine, make sure the oil level is above the full mark
Add oil to bring it up to this mark if necessary. You then start the engine
and after the oil pressure's up, shut off the engine and wait for one minute
(count to 60 slowly) before making the oil-level check.

air pressure in the wiper motor so
that you can position the wiper
blade out of your line of vision.
)With the air pressure bled off, the
blade will stay put and won't creep
back across the windshield.
There've been some changes in the fuels recommended for the M35A1.
The latest poop is in LO 9-2320-235-12 (Nov 63):
Grade DF2 Fuel (Spec VV-F-800)--not to be used below +32F. /
Grade DFI Fuel (Spec VV-F-800)--not for use below 10 F
Grade DFA Fuel (Spec VV-F-800)-all temperatures.
Gasoline (MIL-G-3056)-all temperatures. -
CIE fuel (MIL-F-46005)-all temperatures.
Aviation gas is OUT. You NEVER use it.
In ser icing the air cleaner. sou
first inspect the seals on both ends
of the element for cracks, narps
and signs that dirt is passing into
the engine. If the seals look like
they're in good shape, then clean
the element. Use an air gun if you
can. Never strike the air-cleaner
element on its lip because this can
damage the lip seal. A damaged lip
seal can let dirt leak in and ruin
SIf you can't use compressed air,
hold the element vertically and
gently pat the sides. Don't beat it
to death. Before you assemble it
again, clean the air-cleaner base
and canister with a rag. When you
put the element back in, take spe-
cial pains to get it seated right on
the upper and lower seals.
If you have trouble clamping the canister to the base assembly, check to
be sure the element is seated right. Otherwise, you could seriously damage
the element. \11 I I

Overcleanin the air cleaner and changing the element

trucks nov have an air-cleaner restriction gage on the dash-

Don't clean the air-cleaner until the red flag in the

AIR COMPRESSOR STRAINER-
The strainer shown on page 138
of your TM 9-2320-235-20 (Jan 62)
is no longer on the vehicle. The
one you now have is a composition
type. To service it you reach into

BRAKE-SHOE RETURN SPRINGS-
1 Make sure your brake-shoe return-spring ends are
positioned in the rao oblong holes near the top
brake-shoe anchor-pins. Some vehicless have come
from the factors with one or other of the brake-
spring ends positioned in the top brake-shoe assem-
bl and .our brakes won't release right. If .ou have
brake troubles such as your brakes heating up. take
off the wheel and check the brake-shoe return-spring
ends to make sure they're positioned right.
BRAKE FLUID LINE -
The line from the master cylin-
der to the air-over-hydraulic unit
sometimes cracks at the master-
cylinder end. This is a steel line
and it splits along the seam. Check
this line for leaks every time you
get under the %ehiclt.
AIR LINE FIX-
There's only 1 / 16-in clearance between the main
air line from the air compressor and the upper radia-
tor brace. The twisting of the radiator when the
vehicle is in motion can rub the line against the brace
and cut it. This is a copper line and your best bet is
to twist it out of the way so it clears the brace by
about /2 inch. Use a line-bending tool so you can
bend the line without crimping it.
The fuel-filter inlet and outlet
lines get rubbed by their holding
clamp and then they leak. To pre-
vent this, be sure you got enough
slack and position 'em so they don't
rub against sharp edges that would
damage them. Check them often
for chafing and rubbing.

OIL-FILTER DRAIN- PLUG-
You drain oil filters and replace the filter elements. The re-
cessed pipe-plug, FSN 4720-289-0591, (Item 18 on page 13 of
your -20P) is hard to get out because you have to work from the
bottom instead of the top like you do with most other mlita ry
vehicles. Late production vehicles have a new plug that you can
remove and install with the 7/16-in open-end wrench in the
general mechanics tool set.
b When you take out the old plug to service the oil filter during
normal maintenance, replace it with the new plug, FSN 4730- .
080-7044, (Part No. 444783). -
Change the oil filters when you
drain the crankcase. You do this
semi-annually (or 6,000 miles).
The fuel line from the main tank
to the injector pump can wear out
in a hurry if you let it rub against
the winch drive-shaft. If you see
it's rubbing, put a clamp on it or
tape it to keep it out of the way.
DIFFERENTIAL DRAIN PLUGS-
SThe differential drain-plugs are hard to screw in and out. The
best wa.% is to stick in a close-fitting wrench the full depth of the
recess in the plug. Keep a 90 angle between the wrench handle
and the recess in the plug to keep the wrench from slipping and
J damaging the plug.

There's a new and stronger clutch disk in the supply system but it goes under
the same FSN-2520-870-3744--as the old clutch disk. You can tell the new

metal surface of the disk or hub.
The hose assembly fuel-injector-overflow-and-return-line-to-fuel-filter inlet
(Part No. 7748985), Item 19 on page 13 -20P (Jan 62) rubs on the engine
block and wears out quickly. There's a new replacement ready for this
under FSN 2910-081-4211. With this you also need Tee, FSN 4730-088-8666;
Elbow, FSN 4730-851-0174; and Elbow, FSN 4730-851-0173. With these parts
you route the hose so it misses the engine block.

Is there any one "best" way to protect an M67 recoilless rifle when trans-
porting it in a vehicle? The CO's livid 'cause our weapons sometimes wind up
a ride with broken lock rings, damaged hinge blocks, busted instrument lights
and telescopes, and so on.

Sgt C. S.
Dear Sergeant C. S.,gt C.
Y'r right, Sarge. About all the pubs do is to imply that the best way to get
a weapon from here to there is in good condition.
But, here're some tips you might find helpful, depending on how you plan
to transport your M67.
Natch, the best way to carry any man-transportable shoulder weapon on a ve-
hicle is for the gunner and loader to sit with it in their laps.
If one man's stuck with the chore, he can do it this way.
1. Remove the instru- 2. Attach the muzzle 3. Use a piece of cloth 4. Hold weapon sup-
ment light and tele- cover and breech cover to make a pad 8 inches ported between his
scope and put them in to the weapon. square by at least /2 legs, with breech end

the vehicle floor to ing on cloth cushion.
cushion your weapon.
S. For unattended transporting, either put the gun in
0 / its shipping container the way it came, or make a box
r'big enough to hold it safely. Either way, put the in-
r strument light and telescope in their cases and pad the
inside of the box with rags or paper.
Anyway you do it is right, Sarge, as long as the
weapon comes through in fighting condition.

WHAT'S YOUR NUMBER?
Most every piece of equipment in this man's Army has a serial number that's
used to keep track of it. That goes double for modified equipment like the MG
M2 tripod mount, which is converted to the MG M122 for mounting your M60
Some of the modification kits have an identification plate with the new serial
number right on it. No sweat. The plate gets tacked on to the head of the tripod.
But other kits have a conversion poop sheet with the new serial number
stamped on it. The old M2 number on the tripod gets scratched out and the new
one added, along with the other M122 info.
'Course if this new poop sheet gets lost, as some have, your field maintenance
support is going to have to come up with a number.
Does your M122 have its serial number? Well, if it doesn't, you'll want to
check with your support--soonest.

I DON'T RUSH IT
Word's getting around that at least one Nike-Hercules outfit has been gigged
because its launcher shock absorbers were short of oil.
What hurt is that the men in the unit had been following TM 9-1440-250-20
... LO 9-1440-250-20A and the plate on the front of each shock. That is,
they thought they had been.
If there's a sure way of being fooled into thinking that you have enough oil
in the shocks, it's to pour oil into 'em like you're trying to put out a fire.
The biggest letters on the plate for each shock spell it out clear and simple:
Fill Slowly. And the plate explains why ... to bleed air in the shocks completely.
When you pour in the oil slow-like-as if you're loading a stack of flap-jacks
with syrup-it's safe to figure the shocks are filled once the oil starts to run
out the overflow hole.

Meanwhile, you'd be helping things
by making your cables last as long as
possible. When they develop small
cracks in the covering, wrap some elec-

if the cracks are so deep you can see the

COOPERATION & COORDINATION
Those're the two things to remember if you're going to help your support

The TB tells your support people about the inspections, testing and mainte-

How're chances of getting a
word or two in PS on the BRACES
cross-braces of the newer model
RL-31 reel units?
Too many users forget to slide
the brace forward before
swinging it out to lock it in place.
Result: The ends are spread
wide open, which means the
brace has to be repaired before
it can be slid out and locked.
We didn't have this problem
with the old brace. It swung out
-with no sliding required. That's
probably the reason for the
damage, since a lot of us are
used to the older type.
Sgt J. P. M.
Dear Sergeant J. P. M.,
Sounds like a word or two is needed. The point on the brace being slid for-
ward is mighty important to prevent damage and that means all the
way forward, parallel with the crossarms, before swinging the brace to the

to be stored, you release the brace from
the opposite crossarms, swing it all
the way back to the arm that anchors
it, and then slide it back so it can be
pinned in storage position. Otherwise, the brace could swing out

of one of the plugs. Does it look clean?
OK... maybe it does. Just for kicks,

When it comes to electrical and elec-
tronic wiring for aircraft, it's hard to
get off the ground without a copy of
TM 11-530 (3 Dec 59).
It's called, real shrewd-like, "Instal-
lation Practices for Aircraft Electric
and Electronic Wiring," and it gives
you more general poop on the subject
than you'll probably know what to do
It's not exactly a new TM, but it's
one that could easily have been lost

MORE ABOUT YOUR MIG
Sometimes it's the operator who needs a little PM.
Like when you're the operator of a MIG (Metal Inert Gas) Arc Welder, FSN
3431-691-1415, found in your No. 2 Supplemental Tool Kit. There're some
things to keep in mind for your own protection.
There'll be less danger from sparks and burns if you wear light leather
clothing. There're two welder's aprons (leather) listed in DOD Catalog C8405/
25-IL-A (1 Tan 64)-
APRON, WELDER'S, leather, any acceptable color, bib type, button dosing at side, without lapes
or pockets, 36-in long, 24-in.wide, universal size, FSN 8415-255-4558.

at.back, without tapes or pockets with split leg, 42-in long, 26-inr.idei : sil K0i450, Type I,
class 2. '' '
If you don't have leather clothing, then wear: heavy, dark-colored clothing.
Make sure that your neck area's not exposed.
You need good ventilation (but not a draft) to protect yourself against ozone
gas poisoning. It's a good idea to take a fresh-air break every hour.
Make sure your welding helmet has a No. 10 shade (FSN 4240-273-8590),
when you're using from 75 to 200 amps, and a No. 12 shade (FSN 4240-273-
8591), when using over 200 amps.
Your welder has a selenium rectifier. If it works wrong it
might give off selenium oxide, which is dangerous. Should '-.
this happen, don't breathe the fumes coming from thec' '..
"burned-out" rectifier. Report it pronto.
You'll want to have a copy of TM 5-3431-200-15 (Aug62) '.

And you're flying blind with that Gar Wood crane-shovel M-20A(F) or M-20B

Here're some parts that're available in supply to put those on-the-blink in-

These'll help you to "see" what's going on.
Dear Editor, WHAT'S COOKING ?
We've solved a problem we had with the M1937 field range.
In order to remove the packing gland from the valve stem body of the fuel
S-----,-i ,.d r A VALvE STEM \ PULL OUT I
S Take the air input valve stem and sciew it into the packing gland as far as it will go.
Then back it of one-fourth turn to be sure the threads aren't engaged with valve stem
threads. Pull the o!d packing gland out with the ITlike end of the valve.
When ice picks, pocket knives, etc., are used for this job, they can slip and
cause an injury and they can also damage the equipment.

Where can I pick up some quick
info on "combat gasoline?" And
just how does it differ from the
Capt H. E. B.
Dear Captain H. E. B.,
Supply info on both "combat" and
non-combat gasoline can be found in
Federal Supply Catalogs C9100-IL (1
Dec 63) and C9100-ML (1 Dec 63).
Briefly, the "combat" type gasoline is
made by a different formula. This is
spelled out in specification MIL-G-
3056. This formula gives it three dis-
tinctive characteristics. It makes start-
ing easier over a wider temperature
range; it's uniform in volatility; and
it has additives to retard gum deposits
and permit long-term storage.

Your M332 1 /2-ton ammunition
trailer's cross-country and highway total
(gross) weight is 5800 pounds. Your
ammo (payload) should never be more
than 3000 pounds.
It says this on the M332's data plate
it's correct. Ammo loads of 5800
pounds and maximum loads of 7000 and
8000 pounds are too much.
Remember, ammo payload should
not be more than 3000 pounds, the
lunette weight no more than 440
pounds and the trailer's total gross
weight should not exceed 5800 pounds.
Stick to the M332's data plate regard-
less of what's been said before ... even

CARBON TET'S GONE
The Army's no longer using carbon
tetrachloride, so forget about using it in
your maintenance work. It's just plain
dangerous. See these tech bulletins
Hold it on that item "Take The Lead"

last three paragraphs. Forget all about
switching jacks on the voltage regulator
about what solvents and cleaners to
use: TB Med 35, TB Sig 327 and TB 9-

tet is in MIL STD 36030 (22 Mar 61).
or you might foul up other checks you'll

is OK, tho.
