cap screws 70 to 90 lb-ft. [9,7 a 12,4 kg-m.]

and
the cover screws 15 to 25 lb-ft. [2,1 a 3,4
kg-m.].
The ring gear screws on axles with Powr-

Lok
differentials should be torqued as follows:

Model
30 and 44 axles 35 to 55 lb-ft. [4,84 a 7,60 kg-m.].

N-24. TRAC-LOK DIFFERENTIAL
As
optional equipment
Trac-Lok
Model 44 differen
tial
is available on all Jeep Universal vehicles equipped with semi-float flanged axle shafts.
A
conventional differential transmits all of the
ring
gear torque through the differential gears to the axle shafts. Torque is at all
times
equal on the axle shafts, and if one wheel slips, the other wheel

can
only put out as much torque as the slipping
wheel.

The
Trac-Lok
differential is similar,
except
that

part
of the torque from the ring gear is trans mitted through clutch packs
between
the side gears

and
differential case. The multiple disc clutches

with
radial
grooves
on the plates and concentric
grooves
on the discs are
engaged
by a preload

from
Belleville springs, plus separating forces from
the side gears as torque is applied through the
ring
gear.

The
Trac-Lok
construction permits differential action when required for turning corners and transmits equal torque to both
wheels
when driving

straight
ahead. However, when one wheel tries to spin due to leaving the ground, a patch of ice,
etc., the clutch packs automatically provide more
torque to the wheel which is not trying to spin.
It
can be
seen
then that the
Trac-Lok
differential
resists wheel spin on bumpy roads and provides
more pulling power when one wheel tries to slip.
In
many cases of differences in traction, pulling
power
will
be automatically provided until both
wheels
start to slip.

In
diagnosis of vehicle operators' complaints, it
is important to recognize two things:

a.
If, with unequal traction, both
wheels
slip, the

Trac-Lok
has
done
all it can possibly do.

b.
In extreme cases of differences in traction, the
wheel with least traction may spin after the
Trac-

Lok
has transferred as much torque as possible
to the non-slipping wheel.
N-25.
Lubrication

The
Trac-Lok
differential requires a special
lubri

cant
and ordinary multipurpose gear lubricants

MUST
NOT be used. Use only 'Jeep* Differential
Oil,
Part
No. 94557.

Trac-Lok
differential may be cleaned only by disassembling the unit and wiping with clean rags. Do not flush the
Trac-Lok
unit.

Note:
The
Trac-Lok
differential is serviced at the
same time intervals as the standard differential.
N-26.
Trouble
Symptoms

If
noises
or roughness, such as chatter, are present
in
turning corners, the probable cause is incorrect

or
contaminated lubricant.
Before any differential is removed and disassem
bled for chatter complaints, the correctness of
lubri

cant
can and should be determined.

A
complete
lubricant
drain,
and
refill
with specified

Limited
Slip Differential lubricant
will
usually
correct
chatter.

The
following procedure is recommended to ensure

complete
removal of old lubricant.

a.
Warm
the lubricant by vehicle road operation,

or
5 minutes of operation in gear at 30 mph with
both
wheels
off the ground on a hoist.

Caution:
Never place the transmission in gear with
the
engine
running when only one wheel of a

Limited
Slip Differential equipped vehicle is raised.
The
vehicle might drive itself off the
jack
and produce damage or
injury.

b.
Drain
lubricant while
warm.
Remove
drain
plug

or
cover to
drain
completely. If cover is removed,

it
may be necessary to replace gasket at this time.

c.
Refill
axle with specified
Limited
Slip Differen

tial
lubricant.

d.
Operate the vehicle for approximately ten miles
[16,09
km.], making at least ten figure 8 turns
to flush the old lubricant out of the clutch packs.

e.
Repeat
steps
b, c, and d, making sure to replace
the cover gasket if required in
step
c.
f. It is possible that slight chatter, requiring ad
ditional
vehicle operation, may remain after
step
e. If chatter persists after 100 miles
[160,9
km.]
of vehicle operation, or remains severe after
step

e above, disassembly and repair
will
be necessary.

Unit
Inoperative

Proper
performance and capabilities of
Limited
Slip
Differentials are
often
misunderstood. No
precise
methods
of measuring
Limited
Slip Dif

ferential
performance are generally available in the field. A functioning unit can be determined by
relatively
simple vehicle operational
tests,
as
follows:

a.
Place one wheel on
good
dry pavement, and the
other on ice, mud, grease, etc.

b.
Gradually
increase
engine
rpm to obtain maxi

mum
traction
prior
to "break-a-way." The ability
to
move
the vehicle
effectively
will
demonstrate

proper
performance.

c.
If extremely slick surfaces, such as ice or grease,

are
used
some
question may exist as to proper per
formance at
step
b. In
these
extreme cases a prop

erly
performing
Limited
Slip Differential
will
pro
vide greater "pulling" power by lightly applying
the parking brake.

N-23.

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

link
is adjusted by
means
of the

special
ball
nut to set the operating lever
with

[2,38
mm.] clearance between the closest
point

of
the lever and the brake backing plate.

i.
The
position
of
this
lever should be checked when

making
a major adjustment or when
relining
the
brakes and
if

clearance before adjusting the brake cable
clevis.

P-14.
Self-Adjusting
Wheel
Brake
Units
Self-adjusting
brakes are standard equipment on

all
late production
'Jeep'
vehicles.
The
wheel brake units consist of a support plate,

two
brake
shoes,
brake
shoe
return springs, self-

adjusting
operating parts, and a wheel
cylinder.
The
automatic adjuster continuously maintains

correct
operating clearance between the brake
lin
ings
and the drums by adjusting the brakes
in
small

increments in direct
proportion
to
lining
wear. This
continuous
adjustment prevents gradual increase

in
the brake pedal
travel
as the
linings
wear. The
adjuster, therefore,
adds
the safety feature of
main
taining
adequate
pedal reserve
during
the service

life
of the
lining.

After
the
lining
wears enough to require adjustment, the adjusting cable or
link
will lift
the lever

into
engagement
with
the next
tooth
of the
star

wheel
when the brake is applied. When the brake
is
released, the
shoes
return to the anchor. The
self-adjuster
utilizes
the movement of the brake

shoes
in a brake application to
actuate
the adjuster
lever.

This
action
will
repeat
on
subsequent
brake applica

tions,
if
necessary,
until
the
shoe
to
lining
clearance
is
reduced to a
point
where the
shoe
movement

is
not enough to
cause
the cable to
lift
the lever

to
the next
tooth.

The
adjusting lever, adjusting screw assembly,

linkage
rods and lever crank parts are
left
hand
or
right
hand parts, NOT interchangeable, and
MUST
be kept
separated.

The
automatic adjuster on the brake system con

sists
of an adjusting screw assembly, adjusting

lever,
two adjusting
links,
and a lever crank, (Fig.
P-10).

Note:
It is not
necessary
to remove the rear axle
shaft hubs to
perform
minor
brake service.

When
replacement of
oil
seals
is also required, hubs must be removed.

On
vehicles equipped
with
self-adjusting brake
assemblies, self-adjustment of the
front
wheel brakes
takes
place
during
reverse wheel brake ap

plication
and the rear wheel brake adjustment
takes

place
during
forward
vehicle brake application.
P-15.
Relining
Wheel
Brakes

a.
When
necessary
to reline the brakes, the vehicle
should
be raised so that all
four
wheels are free.

b.

P-17. Inspection
Inspect the oil seals in the wheel hubs. If the con
dition of any oil seal is doubtful, replace it. Install
the oil seal with an oil seal driver as shown in Fig.

P-9.

Brake
shoes
may be distorted by improper lining installation and linings should be ground true. For
this reason it is recommended that new or re
placement
shoe
and lining assemblies be installed.
Using
brake drum micrometer C-3920 or equi
valent, check all drums. Should a brake drum be rough and scored, it may be reconditioned by grinding or turning in a lathe. Do not remove more
than .030"
[0,762
mm.] thickness of metal .060" [1,52 mm.] overall diameter. If a drum is recon
ditioned in this manner, either the correct factory-
supplied, oversize lining .030"
[0,762
mm.] must be
installed or a shim equal in thickness to the metal
removed must be placed
between
the lining and

shoe
so that the arc of the lining
will
be the same
as that of the drum.

If
it is found when
wheels
are removed that there
is brake fluid leakage at any of the wheel cylinders, it
will
be necessary to replace or recondition the
wheel cylinder (Par. P-21) and bleed the brake lines (Par. P-7).
Whenever the brake lining is replaced in one front
or one rear wheel, be sure to perform the same
operation in the
opposite
front or rear wheel, us
ing the same brake lining part number. Otherwise, unequal brake action
will
result.

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.
