REMOVAL OF STARTING MOTOR
(1)
Disconnect the ground cable at the battery.
(2)
Remove the cable at the starter.
(3)
Disconnect the solenoid lead wire at the sole-
noid terminals.
(4)
Remove the one stud nut and one bolt attach-
ing the starting motor to the flywheel housing, slide
the Automatic Transmission oil cooler tube bracket
off the stud (if so equipped) and remove the starting
motor and removable seal.
TESTING THE STARTING MOTOR
(Bench Test)
free Running Test
(1)
Place the starter in a vise and connect a fully
charged, 12 volt battery to the starter as follows:
(2)
Connect a test ammeter (100 amperes scale)
and a carbon pile rheostat in series with the battery
positive post and the starter terminal.
(3)
Connect a voltmeter (15 volt scale) across the
starter.
(4)
Rotate the carbon pile to the full-resistance po-
sition.
(5) Connect the battery cable from the battery
negative post to the starter frame.
(6)
Adjust the rheostat until the battery voltage
shown on the voltmeter reads
11
volts. The amperage
draw should be as shown in specifications.
Locked-Resis
tun
ce Test
(1)
Install the starter in a test bench.
(2)
Follow the instructions of the test equipment
manufacturer and test the starter against
the
follow-
ing specifications.
(3)
With applied battery voltage adjusted to
4
volts, the amperage draw should be as shown in speci-
fications.
SERVICING THE STARTING MOTOR
Disussembly
(1)
Place the gear housing of the starter in a vise
equipped with soft jaws. Use the vise as a support fix-
ture only.
DO NOT
clamp.
(2)
Remove the two through bolts and the starter
end head assembly.
(3)
Carefully pull the armature up and out of the
gear housing and the starter frame and field assem-
bly. Remove the steel and fiber thrust washer.
NOTE: The wire of the shunt field coil is soldered
to the brush terminal. One set
of
brushes is con-

nected to this terminal. The other pair of brushes
is
attached to the series field coils by means of a
terminal screw. Carefully pull the frame and field
assembly up just enough to expose the terminal
screw and solder connection of the shunt field at
the brush terminal. Place two wood blocks between
the starter frame and starter gear housing to fa-
cilitate removal of the terminal screw, Fig.
2.
(4)
Support the brush terminal by placing a finger
behind the terminal and remove the terminal screw.
(5) Unsolder the shunt field coil lead from the start-
er brush terminal, Fig.
3.
The
4
series coil starters do
not have a wire soldered at the brush terminal.
