S-6. U-Shackles

The
threaded bushings of the U-shackles, used to

early
1957 production, are anchored solidly in the frame brackets and spring
eyes,
and the oscillation
is taken
between
the threads of the U-shackle and
the inner threads of the bushings.
On
early production of Models
CJ-3B, CJ-5,
and

CJ-6,
six bushings are used with right-hand threads

and
two with left-hand threads. The right-hand
threaded bushings have plain
hexagon
heads. The
left-hand bushings have a
groove
around the heads.
The
two left-hand threaded U-shackles are identi­
fied by a small forged
boss
on the lower shank of
the shackle. They are used at the
left
front spring

and
the right
rear
spring with the left-hand thread­
ed end
DOWN
at the spring eye. The left-hand threaded parts have
been
cancelled in the produc­
tion of Models
CJ-3B,
CJ-5 and CJ-6. All later production vehicles, up to early 1957, use all right-

hand
threaded parts.

When
replacing shackles and bushings on
these

vehicles, examine the parts carefully for parts of
the same
type
removed must be reinstalled. A right-hand threaded bushing cannot be installed
satisfactorily after one having left-hand threads
has
once
been
installed.
U-shackles are installed with the bushing
hexagon

heads at the
outside
of the frame.
When
installing a new U-shackle or a shackle bush­
ing,
follow
the procedure outlined
below:

Install
the shackle grease seal and retainer over the threaded end of the shackle up to the shoulder. In-

GENERAL
The
body
is of
all
steel construction with mountings
that provide a secure attachment to the frame.

All
major panels are of No. 18
gauge
steel. All
open

edges
of the panels are turned under, reinforced

and
flanged to provide strength. These panels are reinforced with
"U"
sections
and welded. All com­

ponent
panels are seamed and welded
together.
The
body
is insulated from the frame with insulator shims placed
between
the
body
and frame and
held in position by the
body
bolts.

The
instruments and controls, mounted on the
instrument panel are within clear view and easy
to reach.

Note:
A new floor pan cover plate has
been

released on late CJ-5 and CJ-6 models, that is
identified by a stamped oval-shaped bubble or
relief, located to the right of the accelerator treadle.

U-2. EXTRA
EQUIPMENT

Much
of the utility of the
*
Jeep*

the extra equipment which has been designed to adapt it for farming and industry. The mainte­
nance and use of
some
of this equipment is out­
lined
in this section.

U-3.
Governor Assembly

The
Novi governor is supplied for models equipped

with
the F4 engine.
This
is a centrifugal type governor and is illustrated in Fig. U-2. Complete

installation
instructions are supplied with each
assembly. Adjustment and operating procedures

are
given below.

U-4.
Governor Adjustment

a.
Adjust the carburetor to obtain smooth
engine

idle at 600 rpm., then
stop
the engine.
b.
Check
throttle linkage to ensure maximum
throttle opening. Be certain that throttle and
governor linkage is free.

c.
Place the carburetor throttle in wide-open posi­ tion and
pull
the governor control handle out to
the last notch. Adjust the governor to bellcrank

rod
so that the linkage
will
hold the carburetor
throttle in wide-open position.

d.
Close the governor control and start the
engine

Again
pull
the control out to the last notch and

adjust
the length of the cable at adjusting yoke so
that the
engine
will
run at
2600
rpm. Close the

control
to recheck the linkage for free action and
to make sure the
engine
will
return to 600 rpm.
idle speed.

If
the
engine
runs faster than this speed,
loosen

the lock nut which locks the governor hand control
handle on the dash to the rod and back off the
handle until the carburetor idle speed adjusting

screw
bears on the stop. Tighten the lock nut.
In
the absence of electrical tachometer equipment,

engine
speed may be determined by the speedom­
eter. Safely
jack
up the
rear
wheels and be sure the front wheel drive is not
engaged.
When driving
the
rear
wheels in high or direct transmission gear,
the
speedometer
will
read from 13j^ to 15 mph. [21.6 to 24.0 kph.] at an
engine
speed of from 900
to 1000 rpm.

Novi Governor Operation /

The
Novi governor is directly belted to the F4

engine
as no clutch is provided to disconnect the
drive.

To
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.

safe, easy hitch for towing a
