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.

The
entire windshield and frame assembly may be
lowered down on top of the hood.
This
is accom­ plished by unlatching the retaining catches mount­
ed on the cowl
above
the instrument panel. When lowered do not
fail
to strap it down with the strap provided which is mounted at the top of the

radiator
guard.

A
stationary
type
windshield is used on all vehicles
equipped with
soft
or canvas
tops.
A hinged ven­ tilator mounted in the center of the panel directly
under the
glass
is provided for ventilation. The

glass
is installed in the same manner as on Models
CJ-5,
and
CJ-6.

Vehicles equipped with metal enclosure employ a
stationary windshield which is the same as that used with the canvas top
except
that it has a higher

silhouette
and is wider.
Glass
installation is the same as
CJ-5,

top should be installed on the vehicle immediately

and
washed with a mild soap; then
give
the top a

quick
and thorough rinsing.

Miscellaneous information included in this sectioi

U-2. EXTRA
EQUIPMENT

Much
of the utility of the
*
Jeep*
Universal
is due to
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.

U-7.
Pintle Hook

The
standard type pintle hook, Fig. U-1, affords a
safe, easy hitch for towing a
trailer
or other vehicle. 357

u

MISCELLANEOUS
Designed primarily for use on the road, a safety

latch
locks the hook in the closed position and two
eye
bolts
are provided for attachment of safety chains which should be crossed when installed, to
prevent the hooks from jumping out of the
eyes.

Keep
the attaching
bolts
tight at all times. When

lubricating
the vehicle, place a few drops of oil on the hook and safety latch pivot pins.
FIG.
U-l—PINTLE HOOK
U-8.
Pintle Hook Installation

Six
holes
are provided in the frame
rear
cross mem­
bers of 'Jeep* Universals for the installation of
pintle hooks and safety chain eye bolts. On most vehicles, the pintle hook is attached using the top
four
holes
and the eye
bolts
are attached using the
lower two holes. On 'Jeep* Universals equipped
with
tail
gates,
the position of the hook and the eye must be changed to provide proper clearance.
On
these
vehicles, use the lower four
holes
for at­taching the pintle hook and the upper two
holes
for
attaching the safety chain eye bolts.
U-9.
Front
Bumper
Weight

The
best
performance of a four-wheel drive vehicle
is obtained when the load is equally distributed for
traction
on the front and
rear
wheels.
This
weight
distribution is disturbed when the vehicle is used
for drawbar work as the load on the
rear
wheels is increased and that on the front wheels decreased.
The
addition of a 265 pound front bumper weight
equalizes the load.
When
the load is equalized the front and
rear
axles
do approximately the same work which results in
prolonged life of
these
parts and considerably more
satisfactory performance.
The
bumper weight, Fig. U-3, is held in place by
four
bolts
and is provided with hand
holes
for lift­
ing.
Do not add sand
bags
or other
weights
in the vehicle. When driving over rough
terrain,
with the
weight in place, the driver should exercise due care.
