The
steering knuckle pins pivot on tapered roller
bearings. Replacement of
these
bearings requires

removal
of the hub and brake drum assembly,
wheel bearings, axle shaft, spindle, steering tie rod,

and
steering knuckle. Disassemble the steering
knuckle
as follows:
Remove the
eight
screws which hold the oil seal

retainer
in place. Remove the four screws holding
the lower pivot pin bearing cap. Remove the four screws holding the upper bearing cap in place. Re­
move
the bearing cap. The steering knuckle can
now be removed from the axle. Wash all parts in cleaning solvent. Replace any damaged or worn

parts.
Inspect the bearing and races for scores,
cracks,
or chips. Should the bearing cups be damaged,
they
may be removed and installed with

Reassemble
and
Bearing Preload

Reverse
the procedure of Par. M-8 to reassemble
the unit. When reinstalling the steering knuckle, sufficient shims must be installed under the top

bearing
cap to obtain correct preload on the bear­
ing.
Shims are available in
these
thicknesses: .003"
[0,076
mm.] .010"
[0,254
mm.] 005"
[0,127
mm.] .030"
[0,762

Install
one each of the
above
shims at the top only.
Install
the bearing caps, lockwashers, and screws,

and
tighten securely.
Check
the preload on the bearings by hooking a

spring
scale, Tool C-690, in the
hole
in the knuckle

arm
for the tie rod socket.
Take
the scale reading when the knuckle has just started its
sweep.

The
kingpin bearing preload should be 12 to 16 lb. [5,43 a 7,24 kg.] with the oil seal removed. Remove

or
add shims to obtain a preload within
these

Knuckle
Oil Seal
Remove the old steering knuckle oil seal by remov­ ing the
eight
screws which hold it in place.
Earlier

production vehicles are equipped with seals con­ sisting of two oil seal halves.
Later
production vehicles are equipped with oil seal assemblies con­
sisting of a split oil seal and backing ring assembly,

an
oil seal felt, and two seal retainer plate halves.

Examine
the spherical surface of the axle for scores or scratches which could damage the seal.
Smooth any roughness with emery cloth. Before installing the oil seal felt, make a diagonal
cut across the top side of the
felt
so that it may be
slipped over the axle.
Install
the oil seal assembly

in
the
sequence
given above, making sure the

backing
ring (of the oil seal and backing ring as­
sembly) is toward the wheel.

After
driving in wet, freezing weather swing the
front
wheels
from right to
left
to remove moisture

adhering
to the oil seal and the spherical surface of
the axle housing.
This
will
prevent freezing with

resulting
damage to the seals. Should the vehicle be
stored for any period of time, coat
these
surfaces

with
light grease to prevent rusting.

The
purpose of caster Fig. O-S, is to provide steer­
ing stability which
will
keep the front wheels in the
straight
ahead position and also assist in straighten­
ing up the wheels when coming out of a
turn.
Caster
of the front wheels is preset. If the angle of

caster,
when accurately measured, is found to be

incorrect,
correct it to the specification given at
the end of this section by either installing new

parts
or installing caster shims
between
the axle

pad
and the springs.

If
the camber and toe-in are correct and it is known
the the axle is not twisted, a satisfactory check

may
be made by testing the vehicle on the road.
Before road testing, make sure all tires are properly

inflated,
being particularly careful that both front
tires are inflated to exactly the same pressure.
If
vehicle turns easily to either side but is
hard
to
straighten out, insufficient caster for easy handling of vehicle is indicated. If correction is necessary, it

can
usually be accomplished by installing shims

between
the springs and axle pads to secure the
desired
result.
0-11-
Front
Wheel
Turning
Angle
When
the front wheels are turned, the inside wheel
on the
turn
travels in a smaller circle than the out­side wheel, therefore, it is necessary for the wheels
to toe out to prevent the tire on the inside wheel

frOm
being scuffed sideways.
This
angle for toe out
on turns is designed to permit both front wheels to

turn
on a common center by having the ends of the
steering
knuckle
arms closer
together
than the king­

pins.

To
avoid possible damage to the universal joints
on the front axles of 4-wheel drive vehicles, it is advisable to check the turning angle.

Shimmy
Wheel
shimmy may be caused by various condi­
tions in the wheels, axle or steering system, or a
combination of
these
conditions. Outlined below

will
be found the usual corrections of this fault:

a.
Equalize
tire pressures and see that they are
according
to specifications.

b.
Check
the wheel bearings for
looseness.
Be sure
that the inner wheel bearing race is not too
loose
on the spindle.

c.
Remove both steering knuckles and carefully inspect the upper and lower king pin bearings.

Inspect
the bearing cups for evidence of brinelling,
pitting, or fretting. Any bearings that show the slightest imperfection must be
replaced.
Reassemble

and
lubricate the front axle and steering linkage,
installing
new steering knuckle oil seals if present
seals show any wear.

d.
With
full
weight on the front wheels and one

man
working the steering play with the steering
wheel, a second man should closely observe the steering bell
crank
for any rocking motion and the
double tie rod socket for any rocking motion or

looseness
at both points. Replace the complete bell
crank
assembly if it has even the slightest rocking motion. The same applies to the double tie rod
socket.
e.
Check
wheel run-out.
This
check should include
radial
run-out and wheel
looseness
on the hub.
f- Test wheel balance—check for blowout patches,
uniform
tire tread, vulcanized tires, mud on inside
of wheels, and tires creeping on the
rims.

g.
Try
switching front wheels and tires to the
rear,
criss-crossing
them in this operation.

h.
Check
for front
spring
sag. Also check for broken

spring
leaves, broken center
spring
bolt,
loose
spring

clips
(or tight clips), over-lubrication of spring leaves, spring shackle bracket
loose
on frame, and

loose
rear
spring shackle. Be sure that the shock
absorbers
are operating properly to eliminate bob­bing of the front end.

i.
Check
brakes to make sure that one
does
not

drag.

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

engine
as no clutch is provided to disconnect the
drive.

operate the vehicle
WITHOUT
governor con­
trol,
push the governor hand control all the way
IN
against the instrument panel.

To
operate the vehicle
WITH
governor control,

pull
the governor hand control handle out. The
hand
control has nine notched positions. Pulling the

control
out to the first notch
sets
the controlled

engine
speed at approximately 1000 rpm. and each successive notch increases the speed 200 rpm.

until
2600
rpm. is reached in the ninth notch. The

hand
control may be released by turning the han­ dle one-quarter
turn
in either direction.

When
the
engine
is being operated under governor

control
(hand control out) the controlled
engine

speed may be
exceeded
at any time by depressing
the
foot
accelerator in the conventional manner to
secure a greater carburetor throttle opening than
that determined by the governor hand control
setting.

U-6.
Governor Maintenance

The
belt tension may be adjusted by raising or
lowering the governor in the slotted
holes
in the mounting bracket. Keep the pulleys and belt free
of
dirt
and oil. Belt slippage
will
affect governor
operation and a tight belt may cause
rapid
wear
of the governor shaft and bearings. Adjust it to
allow Yi' [12,7 mm.] depression midway
between
the pulleys with thumb pressure.
There
is little wear of the internal parts for they
operate in oil. The governor housings are equipped

with
both
fill
and
drain
plugs and also with level

indicating
plugs.
Check
the oil level at each vehicle
lubrication
and change the oil each time the en­

gine
oil is changed using the same grade oil used

in
the engine.

Caution:
Do not
fill
the governor housing above
the level plug. Overfilling
will
prevent governor
control
and possibly cause damage to governor in­

ternal
parts. The capacity of
these
governors is two fluid ounces [59,15 cm3]. The filler plug is
also a vent which should be cleaned thoroughly at
each oil change to be sure that the vent operates.
