the Brush Holder Plate
ing joint. Apply a bead of brush plate sealer Part NO.
2421847 around the four sides of the joint (Fig. 26).
CAUTION: Sealer must be flowed continuously to
NK81
avoid gaps. After bead
has
been flowed on, use a
brush or small paddle moistened in mineral spirits
to press adhesive into joint. Be sure not to get the
adhesive on the battery and/or solenoid terminals.

Starter Armature
washer, Fig. 22. This will hold the brushes out and fa-
cilitate proper installation of the armature.
(18)
On starters so equipped, solder the shunt coil
lead wire to the starter brush terminal (Fig. 2 4 ) .
(19) Install the brush terminal screw (Fig. 2 ) .
(20) Position the field frame to the exact position
on the gear housing and enter the armature into the
field frame and starter gear housing (Fig.
25);
care-
fully engaging the splines of the shaft with the reduc-
tion gear
by
rotating the armature slightly to engage
the splines.
(21) Install the thrust washer (fiber) and washer
(steel) on the armature shaft.
(22) Position the starter end head assembly and in-
stall
the starter frame lockwashers and through bolts.
Tighten
the
through bolts securely.
(23) Clean the area at the joint between the brush
holder plate to the field frame and gear housing mat-
INSTALLATION OF THE STARTING MOTOR
(1) Before installing the starting motor, make sure
the starter and flywheel housing mounting surfaces
are free of dirt and oil to insure a good electrical
contact.
(2) Position the starter to the flywheel housing re-
movable seal.
(3) Install the starting motor, washer and bolt, the
automatic transmission oil cooler tube bracket and the
washer and nut.
NOTE: When tightening the attaching bolt and nut
be sure to hold the starting motor pulled away from
the engine to insure proper alignment.
(4)
Attach the wire at the solenoid switch terminal
and cable to the starter terminal.
( 5 )
Connect the battery ground cable and test the
operation of the starting motor for proper engine
cranking.

STARTING MOTOR CIRCUIT TESTS
lnsuluted Circuit Test
(1) Test the battery electrolyte specific gravity.
Specific gravity should be 1.220 or above. If the bat-
tery specific gravity is below 1.220, recharge the bat-
tery to a full charge before proceeding with the test.
(2) Turn the voltmeter selector switch to the
4
volt
position.
(3) Disconnect the ignition coil secondary cable.
(4) Connect the voltmeter positive lead to the bat-
tery positive post and the voltmeter negative lead to
the solenoid connector which connects to the starter
field coils.
NOTE: The voltmeter will read off the scale to the
right until the starter is actuated.
(5)
Connect the remote control switch to the bat-
tery and solenoid terminal of the starter relay.
