H-118. Starting Motor Test —
Genera!

To
obtain
full
performance data on a starting motor, or to determine the cause of abnormal
operation, the motor should be submitted to no-
load and locked armature
tests,
with equipment designed for such
tests.
A high-current variable resistance is required to obtain the specified volt­
age at the starting motor.
This
is necessary since
a
small variation in the
voltage
will
produce a
marked
difference in the current
drawn.

H-119.
Starting Motor No-Load Test

This
test
requires a DC voltmeter capable of
read­

ing
voltages
in a 12-volt
circuit,
a DC ammeter

with
maximum range of several hundred amperes,
a
high-current variable resistance, an rpm. in­

dicator,
and a fully-charged, 12-volt battery.

a.
Connect a jumper lead
between
S terminal
and
large battery terminal of starter solenoid.
Con­
nect voltmeter
between
either of
these
terminals (positive) and motor frame (negative, ground).

Connect
ammeter and variable resistance in series

between
positive terminal of battery and battery

terminal
of solenoid. Set up rpm. indicator to show starting motor speed.
b.
Initially,
adjust variable resistance to a value of
approximately .25 ohm. To complete the
circuit,

connect negative terminal of battery to motor

frame.
Adjust variable resistance to obtain a volt­ meter reading of 10.6 volts;
note
speed of starting motor and ammeter reading. Motor speed should
be
6750
to
10,500
rpm.; ammeter reading should
be 50 to 80 amperes.
c. Rated speed and current indicate normal condi­
tion of the starting motor. Low speed and high
cur­
rent
may show friction; this could be caused by
tight, dirty, or worn bearings, bent armature shaft,

or
a
loose
field
pole
shoe
dragging against the

armature.
It could also be caused by a short-cir­ cuited armature, or by grounded armature or field
coils.

d.
Failure
to operate and high current indicates

a
direct short circuit to ground at either the battery

terminal
or field coils.
e.
Failure
to operate and no current are usually
caused by broken brush springs, worn brushes, high insulation
between
commutator
bars,
or
some
other
condition preventing
good
contact
between
the brushes and commutator. It can also be caused by
open circuit in either the field coils or armature coils.
f. Low speed and low current show high resistance due to poor connections, defective leads, dirty com­
mutator, or one of the conditions mentioned in e,
above.
g. High speed and high current indicates a short
circuit
in the field coils. H-120-
Locked
Armature Test

This
test
requires a DC voltmeter with range ap­

propriate
to read
voltages
in a 12-volt
circuit,
a DC
ammeter with maximum range of several hundred
amperes, a high-current variable resistance, a
clamping fixture to lock
together
the motor shaft

and
case, and a fully-charged 12-volt battery.

a.
Connect a jumper lead
between
S terminal and
large battery terminal of starter solenoid. Connect
voltmeter
between
either of
these
terminals (posi­
tive) and motor frame (negative, ground). Connect
ammeter and variable resistance in series
between
positive terminal of battery and battery terminal
of solenoid.
Install
clamping fixture to lock motor
shaft and case
together
securely.
b.
Initially,
adjust variable resistance to approxi­
mately .05 ohm. To complete the
circuit,
connect
negative terminal of battery to motor frame. Ad­

just
variable resistance to obtain a voltmeter
read­
ing of 4.0 volts. Ammeter reading should be 280
to 320 amperes.

H-121.
Solenoid Starter Switch — Delco

The
solenoid-type switch is mounted directly on
the starting motor.
This
type of switch is energized
by turning the ignition key to the extreme right position. Should the solenoid switch
fail
in service

it
is necessary to install a new assembly.

Should
a starting motor
fail
to deliver maximum power the fault may be due to
voltage
drop at the

starter
switch contacts due to corrosion or burning.

Check
the switch by comparing the
voltage
at the
battery across the terminals. The
voltage
drop
should not exceed .05 volts per 100 amperes.
In
order to remove the starter solenoid, it is neces­

sary
to remove the starter assembly.

H-122.
ELECTRICAL
INSTRUMENTS

H-123.
Fuel
Gauge —
CJ-3B

The
fuel
gauge
circuit is composed of the indicating

unit,
mounted on the instrument panel, and the
fuel tank unit, connected by a single wire through the ignition switch.

Should
the
gauge
fail
to register, check all wire con­ nections to be sure they are tight and clean; also
be sure both units are well grounded. If, after this
check, the
gauge
does
not indicate properly, remove
the wire from the tank unit and connect it to a
new tank unit which must be grounded to the tank

or
frame for
test.
Turn
the ignition switch "ON"
and
move
the float arm through its range of travel,
watching the dash unit to determine if it indicates
correctly.
If it fails to do so the trouble is probably

in
the dash unit and it should be replaced.

Should
a new tank unit be unavailable for this
test,
disconnect tank unit wire at the instrument panel

gauge.
Connect one lead of a 12 V, 1 CP
test
light
to the instrument panel unit terminal and with the
ignition switch
"ON"
ground the other lead. If the
unit is operating correctly the pointer
will
move

approximately three-quarter across the
dial.
Do not attempt to repair either unit; replacement
is the only precedure. 211

have
two
single speed wind­
shield wiper motors mounted above
the
windshield inside
the
vehicle. The wiper motors
are
operated

and
controlled
by a
switch located
on the
instru­
ment panel.

Current
production vehicles with stationary wind­
shield have
a
two-speed
electric windshield wiper motor mounted below
the
windshield outside
the

vehicle on the driver's side. The wiper motor switch is located
on the
instrument panel
to the

of

the steering column.

H-142.
Two-Speed Wiper Motor

The
two-speed
electric wiper motor
is
operated and
controlled
by a
turn
type, three poled, dash switch,
containing
a 6
amp. circuit breaker.
Current
flow
is directed from
the
battery through
the
ignition
switch
to the
wiper dash switch assembly
to the

two-speed
wiper motor, which passes current from the designated motor brush (high,
low or
park)
to

the armature circuit

[1,651
mm.] shim, the inner
cone
and roller*

sleeve
SP-1997 from Tool W-162, and the pinion
nut.
e. Select the proper pinion adjusting
gauge
to obtain the correct reading for the differential model.

The
pinion adjusting fixture must first be set by the use of a master
gauge
which is included in the
W-99
Kit. Gauge block W-101-A-24 or SP5433 is stamped with the letter H which indicates it is used
to set the adjusting fixture on Model
27AF
axle differentials. Gauge block W-101-A-22 or SP5453 is stamped with the letters D, G, F, A, C, E and B.
Use the letter E for Model 44 axle differentials.

j.
The
lowest
reading indicates the center of the
differential bearing bore. At this point the dial indi­
cator should read the same as
mark
etched on the
pinion head. If the reading
does
not agree, add or
remove the shims behind the bearing cup until
the readings agree.

k.
The end of each pinion is etched with a plus
(+) number, a minus (—) number or zero (0)
number to indicate the
best
running position for
each particular gear set.
This
dimension is con­
trolled by shimming behind the inner pinion bear­ ing cup. Therefore if a pinion is etched (-f-2), this
pinion would require .002"
less
shims than a pinion
etched "0". By removing shims the mounting dis­
tance is increased which is just what a (+2) etch­
ing indicates. Or if a pinion is etched (—2), add
.002" more shims than would be required if the
pinion were etched "0". By adding .002" shims the mounting distance is decreased which is just what

a
(—2) etching indicates.

Note:
To increase the dial reading decrease shims;
to decrease the dial reading increase shims.

Example:
With a dial reading of minus .001" and
a
pinion marking of plus .002" remove .003" shims
to obtain a higher dial reading of plus .002"

I.
If the original ring and pinion set is to be re­
used, measure the old pinion shim pack and build a
new shim pack to this dimension. Collect shim pack
saved from teardown. Measure each shim separately 297

BRAKE
DRUM
SERVICE
On
rear
wheels, the hub fits inside the brake drum
(Fig.
Q-3). On front wheels, the hub is attached
to the outside of the brake drum (Fig. Q-l). The

brake
drums are attached to the wheel hubs by
five serrated bolts. These
bolts
are also used for
mounting the wheels on the hub. To remove a

brake
drum,
press or drive out the serrated
bolts
and
remove the drum from the hub. When placing
the drum on the hub, make sure that the contacting
surfaces are clean and flat.
Line
up the
holes
in
the drum with
those
in the hub and put the drum
over the shoulder on the hub. Insert five new
serrated
bolts
through the drum and hub and drive
the
bolts
into place solidly. Place a round head of the bolt in a vise. Next, place the hub and drum
assembly over it so that the bolt head rests on it.

Then
swage
the bolt into the countersunk section of the hub or drum with a punch. The runout of
the drum face should be within .030" [0,76 mm.]
total indicator reading. If the runout is found to be greater than .030" it
will
be necessary to reset
the
bolts
to correct the condition.
