PLi'hLINHED BN THE DEPARTMENT OF THE ARMY FOR THE INFORMATION
OF ORGCNIZ TIONAL MI 4NTENANCE AND SUPPLY PERSONNEL.
N.;, rkij mcan' (uI hi it E says-it's for your information to use as your post or major
unit ...ir.mandcr citE, fr It there ..chini in nPS that goes against what is usually done at
$\,our inirallmi.'n. li.,n \our boss (the CO' hai, he lait word.
But. ucaull), th,:r. .hi.uld be lImic or rn. Jdlir-..,,,: between what PS says and what's
actually done. Every word that's printed in PS is reviewed by our people to make sure it's in
agreement or doesn't conflict with TM's, TB's, SB's, MWO's and the rest. And, in addition,
the same people that approve the directives also approve articles for PS Magazine.
Sometimes you'll find that PS gives you information that just isn't in some other publica-
tion. That, too, is logical, since one publication (TM, for example) can't possibly cover every
situation that may arise. In this case, PS supplements what's already been published. A TM
sets minimum standards for maintenance of equipment. If you can do a better job, then more
power to you.
One of PS Magazine's jobs is to get new dope out to you as soon as possible.
The biggest job PS has is to let you know that your equipment is only as good as you and
your buddies want it to be. And you can keep it the best in the world by the right kind of
operation and preventive maintenance. -
That's the story. You take it from there.

You with the M-model vehicles!
S If you've got a 1/4- or 3/4-ton 4x4
truck or a 2-1/2- or 5-ton 6x6 truck,
then make sure you're cleaning the
crankcase- ventilator- valve (alias Don-

Wash the valve, sear, and all orifices
with dry-cleaning solvent or volatile

Put the valve and spring in the valve-

Dear Lt J. J. S.,
Although the trip ticket doesn't say so
-thought everyone knew that the ve-
hicle's technical manual is used when
checking your vehicle. It's right there in
the last sentence of paragraph 8a of
)our TM 9-2810. The trip ticket is
something on which to record the ser-
vice you perform and what you 6nd.
You can add the items the TM has
but your DD Form 110 doesn't have,or
you can scratch thru those that are not
present on the vehicle being checked.

Sorr) but those pesky li'l fasteners
are not an item of supply. 1
They were put there as an ease-of-

to remove your cluster mounting plate
is to turn the studs one-half turn. The
studs disengage from the fasteners and
your cluster mounting plate falls out.
Then these fasteners come loose, and it's
easy to lose 'em.

Take a deep breath and hold it for
a moment, will'ya, 'cause this is all
about the respiration on your hydro-
pneumatic recoil mechanisms on field
Those mechanisms do a lot've breath-
ing, too, and they gorra exhale that air
just like you do. That's why they have
a respirator, or similar device, on the
Srecoil or counter-recoil cylinder. Every
hydropneumatic's got one. Some of 'em,
like in the 105-mm howitzer, are adjust-
able. Some of 'em aren't. But they all
.serve the same purpose. They help re-
duce the shock of counter-recoil by let-
oing air out of the cylinder easy-like.
When they get stopped up with dirt,,
water, paint, grease, or what-have-you,
the air doesn't escape in the right :
amount at the right time and you get a
real nervous counter-recoil action.
So the point of this long-winded yarn
is his:Tokeepyour weapon from pant-
in'and gaspin' and bucking in counter-
recoil, make sure she's respiratin' all -
right. It'd be just plain foolishness to
smother a good weapon.

W e are maminaining a number of

make about the special tool sets being
issued for work on these vehicles:
The standard 15/16-in 12-point
socket, in both 1/2-in drive and even in
the 3/4-in drive sets, will break when
used to pull a very stubborn track-con-
nector wedge-bolr. Not always, by any
means, but too frequently.
We have found that the PROTO tool
Company's Number 7830-H-15/16
heavy dury six point socket, 3/4-in
drive will stand up to the work. We
have set to break our first one. This
socket is designed to be used with an
impact wrench, but it can be used with
the regular 3/4-in drive T-bar very
SAnother thing, if the recess around
the heads of the track sprocket bolts
were enlarged to accept a heavier
socket, that too would prevent lots of

EASY KEPT OIL AND GAS'RECORD
Dear Editor, A
This is for those motor
officers and motor ser- .'
giants who are always
having trouble keeping
the mileage chart for the
(1.000 inile C) or (6,000
mile D) maintenance r "
We have eliminated
charts, graphs, and rec-
ords by using the oil and i
gas consumpton report i
form for each vehicle to
tell us v hen those main-
tenance services are due.
-From the PM roster
you post the due mileage ,
of the next scheduled C ''
or D maintenance to the
oil and gas consumption
report form, and when
daily trip ticket to this form he'll com.
pare the speedometer reading to the
reading for the next scheduled C or D
Your TM 9-2810 allows you a 100-
mile tolerance for the C (1.000 miles)
service and a 300-mile tolerance for the
D (6,000 miles) service. So when you
transfer the mileage of the next C or D
service from the PM roster to this form,
you'll find it very wise to have the form
read 100 miles less on C and 300 miles
less on D. This will cause the dis-
patcher to notify the motor sergeant
that maintenance can now be pulled on
The oil and gas consumption report
form will tell you how many miles the
vehicle traveled during the month and
the amount of oil and gas used. If the
gas or oil used by some vehicles is much
greater than others for the same mile-
age, then a check should be made to find
the cause. (Might be carburetor, condi-
tion of engine, pilferage, etc.).
Mr. Louie Shirrell
Ft Knox, Ky.
(Ed Note-Par. 25, T7, 9-2810 (Oct
53) gives the local commander the go-
ahead on the use of whatever additional
forms he feels are necessary for proper
control of his vehicles.)

For you guys who have the Model
C-37M ACF-Brill 37-passenger, bus, a lot
of mud, dirt and other glob gets around
the field coils and armature of the gen-

Ordnance, they'll put a generator shield
on for you like it says in MWO Ord G784-

If you've got an M38 Jeep that needs
a wiring-harness-assembly-as of now
you have to make one. Use cable (Ord

the supply system. Until it gets there you'll
have to make your own.
