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-10. FRESH AIR HEATER AND

DEFROSTER

Refer to Fig. U-4.

Air
circulation of the
heater
and
defroster
unit
is

accomplished
by the use of a
12-volt,
two-speed

fan
motor.

Outside
air may be drawn
through
the
vehicle

fresh air
intake
shroud
into
the fan and
blown
out
across
the
heater
core
where
it is
heated
by the
hot circulating
coolant
from the
engine.
The
heated

air
then
enters
the transition
duct.
From the transi­

tion
duct
the
heated
air
passes
into
the
heat
distri­
butor
where
it is
distributed
to the
defroster
nozzle

and/or
floor
diffuser.
The
heater
and
defroster
controls
are
mounted
in the
control
panel
on the

instrument
panel. A
three-position
switch
mounted

in the
control
panel
operates
the
heater
