F2-17. Carburetor Idle Setting
The
"Lean

Idle"
Method of Idle Setting is as
follows:

a.
Any scheduled service of ignition system should
precede this adjustment

b.
Connect tachometer to engine.

c.
Warm
up
engine
and stabilize temperatures.

d.
Adjust
engine
idle to speed desired, using throt­
tle idle speed adjusting screw.
e.
Turn
idle mixture screws out (counterclockwise)

until
a
loss
of
engine
speed is indicated; then slowly
turn
mixture screws in (clockwise-leaner)
until
maximum speed (rpm) is reached. Continue

turning
in (clockwise) until speed begins to drop;

turn
mixture adjustment back out (counterclock­
wise-richer)
until maximum speed is just regained

at
a "lean as possible" mixture adjustment.

F2-18. Distributor
The
ignition distributor used with the
Exhaust
Emission
Control
System is the same as that used
on
engines
without
Exhaust
Emission
Control.
Check
the distributor cam dwell angle and point
condition.
Check
ignition timing and adjust to specifications shown on the last
page
of this section.

F2-19.
Anti-Backfire
Valve

The
anti-backfire valve remains closed except when
the throttle is closed rapidly from an open position.
To
check the valve for proper operation, accelerate
the
engine
in neutral, allowing the throttle to close

rapidly.
The valve is operating satisfactorily when
no exhaust system backfire occurs. A further check
to determine whether the valve is functioning can
be made by removing from the anti-backfire valve
the large
hose
which connects the valve to the

pump.
With
a finger placed over the open end of
the
hose
(not the valve), accelerate the
engine
and allow the throttle to close rapidly. The valve is
operating satisfactorily if a momentary air rushing
noise is audible.

F2-20.
Check
Valve

The
check valves in the lines to the air distribution manifolds prevent the reverse flow of exhaust
gases

to the pump in the event the pump should, for

any
reason,
become
inoperative or should exhaust

pressure
ever exceed pump pressure.

To
check this valve for proper operation, remove the air supply
hose
from the pump at the check

valve.
With
the
engine
running, listen for exhaust
leakage at the check valve which is connected to
the distribution manifold.

F2-21.
Air
Pump

Check
for proper drive belt tension with belt tension
gauge
W-283. The belt strand tension should be 60 pounds measured on the
longest
accessible span
between two pulleys. DO NOT PRY ON THE

DIE
CAST
PUMP
HOUSING. To
check the pump for proper operation, remove
the air
outlet
hose
at the pump.
With
the
engine

running,
air discharge should be felt at one of
the pump
outlet
openings. The pump
outlet
air
pressure,
as determined by the relief valve, is preset
and
is not adjustable.

The
air pump
rear
cover assembly, housing the pressed in inlet and discharge tubes, and the pres­
sure
relief valve are the only pump components
recommended for service replacement. These parts
are
to be replaced only when damaged as a result
of handling or in the event the relief valve was
tampered with.

F2-22.
Intake Manifold

Intake
manifold leaks must not be overlooked. Air
leakage at the intake manifold may be compen­
sated for by
richer
idle mixture setting, however, this
will
usually cause uneven fuel-air distribution
and
will
always result in
loss
of performance and
exhaust emission control. To check for air leakage
into the intake manifold, apply kerosene or naph­
tha,
on the intake manifold to cylinder head joints

and
observe whether any changes in
engine
rpm

occur.
If an air leak is indicated, check the mani­
fold to cylinder head bolt torque. The correct torque is 25-35 lbs. ft. [3,46 a 4,84 kg-m.]. If the

leak
is
still
evident,
loosen
the manifold assembly

and
torque-tighten the bolts evenly.
Start
from the center and use proper torque values. Replace the
manifold
gasket if the leak
still
exists.
Clean
both
mating surfaces and check for
burrs
or other ir­

regularities.

Always
torque the bolts evenly to the specified
torque value to prevent warpage.

Drain
the cooling system. Remove the fan belt and remove the cooling fan and pulley from the hub on
the water pump. Disconnect the
hoses
from the
water
pump. Remove the cap screws that secure
the water pump to the timing chain cover; remove
the water pump. Do not disassemble the water

pump;
it is serviceable only as an assembly. When

replacing
the water pump, torque the water pump cap screws 6 to 8 lb-ft. [0,829 a 1,106 kg-m.].

G-16.
Antifreeze Solutions

When
water freezes it expands approximately 9%

in
volume. When water, confined in a cooling sys­
tem, freezes it exerts tremendous pressures causing
serious damage. To prevent freezing, antifreeze can
be added to the water to lower its freezing point.

The
two
types
of antifreeze commonly used today have either a methanol or ethylene glycol base,

and
contain corrosion inhibitors. The only anti­
freeze recommended for the cooling system of

'Jeep'
vehicles is ethylene glycol (permanent type).

Methanol
base antifreeze evaporates with the water
when the vehicle is operated at warmer tempera­
tures and requires more attention to avoid
loss
of
protection. Ethylene glycol base antifreeze seldom
evaporates at normal operating temperatures.

Methanol
solution is injurious to vehicle finishes.
Should
any be spilled on the vehicle, it should be
washed off immediately with a
good
supply of cold water without wiping or rubbing. Under ordi­

nary
conditions, ethylene glycol is not injurious to
vehicle finishes.

Warning.*
Drinking
ethylene glycol antifreeze or its
solutions can be harmful or fatal. Do not use anti­
freeze containers for
food
or beverages.

A
table in Par.
G-2
2
gives
the protection obtained
by the addition of various amounts cf ethylene glycol.
Before installing antifreeze, inspect the cooling sys­
tem to be sure it is clean, leak-proof, and otherwise

in
proper operating condition.
Drain
the cooling system, see Par. G-3. Pour in 3 quarts [3 ltr.] of

clean
water, add the required quantity of anti­ freeze, then add clean water to within 1" [2,54 cm.] of the top of the overflow pipe to allow for expan­
sion when hot. Run the
engine
until it is
warm.

Then
recheck the solution level.
Check
the anti­
freeze protection with a hydrometer reading.

G-l7.
Inhibited Coolant Solutions

All
'Jeep5 vehicles equipped with either the
Hur­
ricane
F4 or Dauntless V-6
engine
should use only

inhibited
year-round, permanent-type
engine
cool­
ant
solutions that are formulated to withstand two

full
calendar years of normal operation without

draining
or adding inhibitors. The
engine
cooling
system should be completely drained and the
rec­
ommended coolant installed every two years. Be-
fo
a
installing the permanent-type solution, inspect the cooling system to be sure it is clean, leakproof,

and
in proper operating condition.

Note:
Water alone, methanol, or alcohol-type anti­
freeze is definitely not recommended for 'Jeep*
Vehicles.

G-l8.
Fan Belt

The
fan, water pump, generator or alternator are
driven
by a V-belt. The drive of the V-belt is on
the side of the V. A fan belt that is too tight
will

cause
rapid
wear of the alternator or generator and
water
pump bearings. If the belt is too
loose,
it may
slip
preventing the water pump from properly cool­
ing the
engine
or the generator or alternator from
properly
charging the electrical
circuit.
Use fan belt
tension
gauge
Tool W-283 to properly adjust belt.

The
fan belt is properly adjusted when it can be

good
preventive maintenance to
replace a badly frayed, worn or cracked fan belt
before it breaks in operation.

To
replace the fan belt,
loosen
the attaching
bolts

at each generator or alternator brace-to-engine mounting and pivot the alternator or generator to­

ward
the
engine

belt over the fan pulley, over the crankshaft pulley,
then over the generator or alternator pulley.
Pull
the generator or alternator away from the
engine

Then tighten the generator

or
alternator mounting
bolts
and check the tension
as indicated above. Reset the generator or alternator as necessary for correct belt tension.
Finally,
torque
the generator or alternator mounting
bolts
25 to 35 lb-ft. [3,4 a 4,8 kg-m.].

Note:
On the Dauntless V-6
engine
when adjusting
the fan belt tension, the alternator mounting
bolts

should be torqued 30 to 40 lb-ft. [4,14 to 5,53

kg-m.].
If a fan belt tension
gauge
(W-283) is
avail­

able, proper tension should be 80 pounds [36,2 kg.].

9. Engine Overheating

An
engine
will
not be damaged by high coolant
temperatures unless the coolant boils. The pres­

surized
cooling system on the 'Jeep' vehicles raises the boiling point of the coolant solution. Should
overheating be encountered, and the fault is be­
lieved to be in the cooling system check for the
following:

a.
Proper coolant level. See
Filling
Cooling Sys­
tem Par. G-2.
b. Poor air flow.
Check
for dirty radiator core. (See Radiator Par. G-5).
Check
for faulty belt
pulley operation, worn or
loose
fan belt, or dam­ aged fan.
Clean,
repair, replace or adjust as neces­

sary.

c. Foaming coolant.
Check
for air leaks at water
pump,
hose
connection and filler cap. Tighten, re­

pair

Check
the following for leaks:
Hoses and clamps, water pump, radiator, head gas­
ket, core plugs and drain cocks, as well as the cylin­ der head or block for
cracks.

f.
Internal
leaks.
Check
for faulty head gasket,

CURRENT-VOLTAGE REGULATORS •
F4 Engine

H-42.
Description and
Operation
For
replacement,
voltage
regulator and generator must be matched for
voltage
and capacity, polarity,

and
common source of manufacture. Otherwise,
either a
loss
of ampere capacity or a burned out generator
will
result.

These
regulators are used with shunt-type gen­

erators
and have three units each with a separate function to perform. These units are the circuit

breaker
unit, the
voltage
regulator unit, and the

current
limiting regulator unit.

H-43.
Circuit
Breaker

It
consists of
an
electromagnet and a set of contacts.

The
contacts are mounted with one on a stationary

bracket,
and the other on a movable armature

which
is controlled by the electromagnet. The movable contact is mounted on a spring arm so that as the contacts open and
close
a slight wiping
action is produced.

The
electromagnet of the circuit breaker has two
windings, one, the shunt coil which is connected across the generator output like a voltmeter and
the other a series coil connected in series with the
generator output like an ammeter.These two coils

are
wound in the same direction so that when the
generator is charging the battery, the magnetism
of the series coil increases the total magnetism.

When
the battery discharges back through the generator, the magnetism of the series coil is re­ versed and the magnetism of the two coils is
opposed.
This
results in a decreased
pull
on the

armature
and spring action
opens
the contacts.

FIG.
H-22—PRESTOLITE VOLTAGE REGULATOR
1—
"ARM"
Terminal

2—
"FLD"
Terminal

3— "BAT"
Terminal
The
sequence of operation of the circuit breaker is
as follows:

When
the generator is not running, the contacts
are
open. When the generator is started, the
voltage
builds up at the armature terminal and in the shunt

coil
and as
soon
as it reaches the value for which
the circuit breaker is calibrated, there is sufficient magnetism created by the shunt coil to
pull
down
the armature, closing the contacts which auto­
matically
connects the generator to the battery.

With
the contacts thus closed the current in the
series coil is flowing from the generator to the battery or in the same direction as the current in
the shunt coil, so that the
pull
on the armature is

increased
by the magnetism of the series coil.

When
the
engine
is stopped and the generator
loses

speed, the
voltage
falls, and as
soon
as the gener­
ator
voltage
drops below the battery terminal vol­
tage,
the current flows from the battery to the generator, reversing the direction of current in the
series coil so that the magnetism created by the series coil
opposes
and reduces the magnetism of
the shunt
coil.
This
reduces the
pull
on the
armature

to a point where spring action
opens
the contacts.

H-44.

function of the

regulator is to hold

thrust
washers just inside the commutator end
head or intermediate bearing as required. The
Bendix
drive retaining pin must not project
beyond the outside diameter of the pinion
sleeve.

H-104.
Bench Test

The
motor should first be checked to see that the
free running
voltage
and current are within specifi­ cations. To
test,
connect the motor to a battery,
ammeter and voltmeter. If the current is too high
check
the bearing alignment and end play to make

sure
there is no binding or interference. Using a

spring
scale and torque arm check the stall torque to see that the motor is producing its rated
crank­

ing power. The stall torque
will
be product of the

spring
scale reading and the length of the arm

in
feet.
If the torque is not up to specifications

check
the seating of the brushes on the commutator
and
the internal connection of the motor for high
resistance. The Bendix
Folo-Thru-Drive
should be checked for correct operation. The Bendix pinion
should be checked to see that it shifts when the motor is operated under no load.

H-105.
Bendix Folo-Thru Drive (Prestolite)
The
Bendix
Folo-Thru
Drive is designed to over­

come
premature demeshing of the drive pinion
from
the flywheel ring gear until a predetermined

engine
speed is reached. See Fig. H-43. No repairs or adjustments are possible on this

drive
and a
complete
new unit must be installed

if
trouble develops.

H-106.
Lubrication
of
Folo-Thru Drive
A
periodic cleaning and relubrication of the drive is advisable, the frequency of which
will
depend on
the type of service to which the vehicle is sub­
jected and the locale of operation.

a.
Remove the starting motor from the
engine
and take off the outboard housing. The pinion and

barrel
assembly
will
be in the demeshed position
on the screwshaft. Do not
move
it forward
until
after
that portion of the armature shaft ahead
of the pinion has been cleaned. If accidentally ro­
tated to the outer end of the screwshaft it
will

lock
in that position and cannot be forced back.

b.
Do not disassemble the drive for any reason.

c.
Do not dip or wash the drive in any cleaning solution.

d.
Do not remove the drive from the armature
shaft. Remove
excess
oil, grease or foreign matter
from
the armature shaft by wiping it with a clean cloth.
