Gear
Refer
to Fig. 0-2.

When
the steering gear arm is installed on early
production vehicles, the line across the face of the

arm
and the end of the shaft should be in align­ ment. On later production vehicles, blind splines
on the lever shaft and in the steering gear arm en­

sure
correct positioning of the arm.

a.
Remove the steering gear arm with a puller
C-3646.

Caution:
Do not use a hammer or
wedge
to re­
move
the steering arm from the shaft and lever.

This
can cause damage to the shaft assembly.

b.
Loosen the lock nut and unscrew the adjusting

screw
two turns.

c.
Remove the side cover screws and washers. Re­
move
the side cover and gasket.

d.
Remove lever shaft.

e.
Remove upper cover plate screws. Remove cam,
wheel tube, and bearing assembly from the housing.
f.
Clean
all parts with suitable cleaning solvent and wipe dry.

g.
After dismantling as outlined above is com­
pleted, inspect cam
grooves
for wear, chipping and
scoring,
also the
ball
races on the cam ends and the
separate
ball
cups. Existence of any of
these
condi­ tions indicates the necessity for parts replacement.

h.
Inspect the tapered stud mounted on the lever
shaft for flat
spots
and chipping. In the case of
either, replacement is usually advisable. Inspect the
lever shaft for wear and
test
the fit of the shaft in
the bushings.

i.
Inspect condition of the oil seal at outer end of
lever shaft and the bearing at top end of steering
column.

of dismantling. Assemble cam, wheel tube and
bearing
assembly in housing, seating the lower

bearing
ball
cup in the housing.
Note:
New plastic retainer type cam bearings are
now available for the Ross steering gears. The new
bearings replace, and are interchangeable with,
the lock ring type cam bearings on gears equipped

with
early type cams.
With
adjusting shims in place, assemble upper
cover and adjust the cam bearings.
Assemble lever shaft in housing and with gasket

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

d.
Install the adjusting screw assemblies. The star
wheel must be installed over the adjusting
hole
in the backing plate.

Notes
Interchanging adjusting screw assemblies

will
cause
shoe
to retract rather than expand.
e. Assemble the lower spring that
fastens
to the
two
shoe
webs.
THE LONG HOOK
END should
be secured in the small
hole
in the secondary
shoe

and
should be
UNDER
the
shoe
web. The short hook end should be secured in the small
hole
in the

primary
shoe.
If the spring is installed correctly,
the long hook end
will
not interfere with either the lever or the star wheel
teeth.

f. Install the anchor block with arrow pointing in the forward direction of the drum rotation. Place the
guide
plate over the anchor pin and using Tool
C-3

guide
plate.
g. Install the lever crank in the small
hole
on the secondary
shoe
web, the
left
lever crank on the left,
and
right lever crank on the right. A
"L"
or
"R"
is
located on the
hexagon
side of the crank for identi­
fication.
Make
certain the lever rotates freely on
the
hexagon
head screw.

fi.
Assemble the short wire link with large hook by

first
inserting the "S" shape
offset
end
into
the
lever crank
hole
which is
closest
to the
hexagon

head and then snap the hook end of the link in the top
groove
of the anchor pin.
i.
Insert the long link with "S" shaped end in the

crank
lever.
Lift
the adjuster lever up
enough
to hook the link in the
slot
of the adjusting lever. The
adjusting lever
will
then
engage
the star wheel

teeth
between
M%
[1,59 mm.]
above
or
below
the centerline of adjusting screw assembly,
j.
Lubricate the wheel bearings and install the

brake
drum and adjust the wheel bearing to the proper preload.
k. Adjust the brakes as described in Par. P-19.

INSTALLING
THE
REAR BRAKE SHOES

Refer
to Fig. P-ll.

a.
Inspect the platforms of the backing plates for
nicks
or
burrs.
Apply a thin coat of lubricant to
the backing plates platforms.
b. On vehicles without a transmission brake,
attach the parking brake lever to the back side of
the secondary
shoe.

c. Place the secondary and a primary
shoe
in their relative position on a work bench.

Q-3. WHEEL
BEARING
SERVICE

Adjustment
of the wheel bearings is
critical
be­ cause it establishes the running clearance of the wheel bearings. Wheel bearing adjustment that is
too
tight
preloads the bearings and causes them
to run hot. Loose wheel bearings permit the drum hub to shift its position on the bearings as thrust loads
vary
with acceleration,
braking,
and cornering.

Loose
bearings also cause
erratic
braking.
To check
the wheel bearings for adjustment, brakes must
be free and in fully released position. 336

Q-4. Checking
Front
Wheel Bearings

Raise
the front end of the vehicle with a
jack

so that the tires clear the floor.

Grip
the tire and
test
sidewise shake of the wheel.

If
bearings are correctly adjusted, shake of the
wheel
will
be just perceptible and wheel
will
turn

freely with no drag.

If
bearing adjustment is too tight, the rollers may

break
or
become
overheated. Loose bearings may cause
excessive
wear and noise.

If
this
test
indicates bearing adjustment is neces­

sary,
follow
the procedure given in Par. Q-5. Loose
bearings
will
cause sidewise shake that is evident

around
the entire circumference of the wheel. A shake that is evident only when gripping the
wheels
in
a plane parallel to the ground, but not evident

around
the entire circumference, probably indicates
looseness
in the steering linkage.

Q-5.
Front Wheel Bearing Adjustment
With
the vehicle on the
jack,
the following proce­

dure
should be followed to adjust the front wheel
bearings on four wheel-drive vehicles.
a. Remove the hub cap, snap
ring,
capscrews, and
washers that attach the driving
flange
to the hub.

b.
Using the
Front
Axle Shaft Drive Flange Puller

W-163,
pull
the driving flange.
c. Bend the lip of the nut lock washer so that the

locknut
and lock washer may be removed.

d.
Rotate the wheel and tighten the adjustment nut until the wheel binds.

Note:
Front
tire and wheel must be rotated by

hand
as the adjusting nut is
tightened
to ensure positive seating of the bearing.

Then
back off the adjusting nut about one-sixth
turn
making sure that wheel rotates freely without
sidewise shake.
e. Replace the lock washers and locknut. Bend
over the lock washer lip.
f.
Check
the adjustment (Par. Q-4). Reassemble the driving
flange
and hub cap. Make certain the
gasket is properly installed
between
the hub and
the flange.

•
Model DJ-5, DJ-6

On
two-wheel drive vehicles, remove the hub cap
and
the wheel retaining nut cotter pin. Rotate the
wheel and tighten the wheel retaining nut until the wheel binds.
Then
back off nut about one-sixth
turn
or more if necessary making sure wheel ro­

tates
freely without sidewise shake. Replace the cotter pin and hub cap.

Q-6.
Rear
Wheel Bearing Adjustment —

Flanged
Axle Shaft

Vehicles
equipped with the
flange
type
rear
axle
shaft require no wheel bearing adjustment. The flanged axle shaft is equipped with a single row,

pre-adjusted,
tapered roller unit-bearing capable of
accepting thrust in either direction. The unit-

bearing
adjustment is built in at the factory mak­
ing shimming or bearing adjustment unnecessary.

Refer
to Fig. Q-6.

Q-7.
Checking
Rear
Wheel Bearings —
Tapered
Axle

Raise
wheel on which adjustment is to be made
by placing a
jack
under the axle housing.
With
hands,
test
sidewise shake and in and out play
of the wheel. If bearings are correctly adjusted,
shake of wheel
will
be just perceptible and the 337
