Engine Oil

For
maximum
engine
protection under all driving conditions encountered during the recommended

oil
change intervals, it is necessary to use only

"MS"
certified
sequence-tested
oils. The term
"MS"
must appear on the oil container singly or

in
conjunction with other designations. "MS" des­
ignated oils are heavy-duty detergent oils that are
formulated to withstand all service conditions in
modern powerplants. Engine oils designated only
as
"ML"
and/or
"MM"
are not recommended and should not be used except in an emergency when

"MS"
oil is not available. Certified
sequence-tested

engine
oils are described on their containers by

such
phrases as:
meets,
exceeds,
excels, or has
proven superior in the
test
requirements,
test
sequences, MS Service
tests,
standards, and service

requirements,
of automotive manufacturers, auto­
makers,
or car manufacturers for MS service or
Service
MS.
It
may be necessary to change
engine
oil more
frequently than normally recommended, depending upon the type and quality of oil used, the severity
of operation conditions, if the
engine
is used for
short
periods in cold weather, or if the
engine
is allowed to idle for excessive periods.

Always
drain
the crankcase while the
engine
is hot since
dirt
and contaminants are then more
likely
to be held in suspension and therefore
will

drain
out more completely.
Drain
the crankcase as follows:

a.
Position the
drain
receptacle under the
drain

plug.

b.
Remove the
drain
plug using the correct size

wrench.
Be careful of hot oil.
c.
Carefully
clean the
drain
plug. Inspect and

replace
the gasket, if deteriorated.
d.
When the oil has drained, replace and tighten
the crankcase
drain
plug. 12

From
these
main passages, the coolant flows around
the
full
length of each combustion chamber.

After
cooling the block, the coolant passes through
ports between the block and each cylinder head.
These
ports direct most of the coolant flow around the exhaust valve area to prevent hot exhaust
gases

from
overheating the exhaust ports.

From
the cylinder heads, the water passes into a
water
manifold between each of the heads and the

water
pump. If the thermostat is closed, the coolant
is ported back to the pump where it is recirculated

back
into the pump and into the engine. After the
coolant heats enough to open the thermostat, the coolant is directed from the water manifold through
a
hose
to the top of the radiator and then through
the radiator which acts as a heat exchanger to cool the fluid. The coolant is then ported through a
hose

from
the bottom of the radiator to the pump, which

recirculates
it back to the engine.

The
cooling system is pressurized. Operating pres­
sure
is regulated by a relief valve in the radiator

cap. The
heater inlet
hose
is connected to a port on
the right bank cylinder head. The outlet
hose
is connected to the heater adapter tube on the water

pump.

c.
It is recommended when using water for coolant
that the cooling system be flushed and checked for leaks twice a year, preferably in the
fall
before
antifreeze is added and in the spring when the antifreeze is drained.

Reverse
flushing
will
aid greatly in removing rust 162

P The
standard parking brakes (Fig. P-3) consist of
cable-controlled linkage for applying the rear wheel

brake
shoes
mechanically. A single cable from the

parking
brake control lever is connected, by means of an equalizer, to cables leading to individual rear

brakes.
A lever attached to the secondary
shoe,

with a link acting against the
primary
shoe,
expands the
shoes
into
contact with the drums.
P-4.
Transmission Brake

The
transmission brake is mechanically operated
by a hand lever through a cable and conduit and is mounted at the rear output bearing housing on the
transfer case. The transmission brake and its
linkage are shown in Fig. P-4.
P-5.
Brake Maintenance
No brake can be
expected
to work well when grease
or oil is allowed to leak
into
the drum from the rear axle. Little braking friction can be obtained

between
brakes and drums when the surface is
covered with grease and oil. For this reason, take
care
not to over-lubricate wheel bearings, forcing

lubricant
past seals. Also, check condition of seals

if
leak is suspected or whenever brake drums

are
pulled.
Whenever
wheels
are removed, it is advisable to
wash the drums with a suitable solvent so that all
grease and dirt are removed. Linings with any
evidence of grease or oil on them should be replaced.
The
hydraulic system should be kept free of dirt

and
moisture.
Use only SAE standard J-1703 Hydraulic
Brake
Fluid.

Caution:
Keep mineral oils, gasoline, or kerosene
out of the system as
they
cause rubber cups to

soften,
swell, and distort, resulting in failure.
P-6.
Brake
Service

To
service the brakes,
follow
the procedure
below:

a.
Check the fluid level in the brake master cylin­
der.
See Lubrication Section, Par. B-40.
b. Check brake pedal adjustment. See Par. P-9.
c. Check brake pedal travel. If the pedal travels more than halfway to the floor, the brake system
must be checked and the self adjusting star wheel mechanisms checked for binding, also the brake
linings should be inspected as
they
may be badly

worn.
How much lining is
left
can only be deter­ mined by visually inspecting the linings. See Par.
P-l6 for relining brakes.

d.
If the brakes pull to one side after adjustment, check tire pressures. All tires must be inflated to recommended pressures to ensure even braking. If
the condition persists, examine the brake linings
for foreign material and clean as necessary. If clean­
ing
does
not correct the condition the linings should be replaced. If the side pull persists, check front
wheel alignment and balance.
e. Check the brake system for leaks by applying a steady pressure on the brake pedal. A leak in the
system
will
allow the pedal to "fall away". If the pedal "falls away" check for a leaking wheel cylin­
der.
Remove
wheels
and drums and carefully check
each cylinder. Also examine all lines and fittings.

Rebuild
or replace all wheel cylinders (Par. P-21)

if
one is
defective
as
they
are all probably in poor condition. If the leak has allowed brake fluid to get
on the linings, the linings
will
have to be replaced.
f. A
"spongy"
brake pedal indicates the pressure of air in the hydraulic system.
This
condition must
be corrected by bleeding the brakes. See Par. P-7.
g. Should the brakes
become
locked so that the vehicle cannot be moved, the brakes may be re­
leased by opening the bleeder screw on any one of the wheel cylinders. Before the vehicle is driven, correct the cause of the condition. The cause may

Transmission Brake Adjustment
The
transmission brake is located on the propeller
shaft at the rear of the transfer case, see Fig. P-4.
The
brake is operated by a cable connection from
the brake handle mounted on the instrument panel.

To
adjust the transmission brake, the following

sequence
should be followed:
Make
sure that the brake handle on the instrument
panel is fully released. Give due attention to the
cable and operating linkage to see that
they
do
not bind. If necessary free up the cable and
lubri­
cate it. Rotate the brake drum until one pair of the
three
sets
of
holes
are over the
shoe
adjusting screw

wheels
in the brake. Use the
edge
of the
holes
in
the brake drum as a fulcrum for suitable adjusting

tool
or a screwdriver, rotate each notched adjusting
screw by moving the handle of the
tool
away from
the center of the drive shaft until the
shoes
are
snug in the drum.
Back
off seven
