Remove wires from solenoid and cable from
clamp or solenoid bracket.
SOLENOID
REMOVE
AND
REPLACE
1. Disconnect field strap.
2. Remove solenoid to drive housing attaching
screws and remove solenoid.
3.
Remove solenoid return spring.
4. Remove shift lever pivot pin.
5. Remove shift lever.
6. Replace by reversing
above
procedures.
CHECK
CURRENT
DRAW
Check current draw of hold-in winding by con-
necting a variable source of
voltage
(in series with
an
ammeter) to the switch terminal of solenoid and
ground. Ammeter should read
14.5-16.5
amps. @
10 volts. To check the current draw of both windings,
ground the solenoid motor terminal and connect a
source of
voltage
(in series with an ammeter) to the
switch terminal of solenoid and ground. The am-
meter should read 41-47 amps.
@
10 volts.
CAUTION:
Either
of the above checks must be
completed
in a minimum length of time to prevent
overheating
solenoid windings. Heating
will
cause
the current draw readings to be below
specifica-
tions
which are based on a temperature of
80°F.
DISASSEMBLE
1. Remove nuts from motor and switch terminal.
2. Remove two screws securing cover and care-
fully
remove cover.
CA
UTION:
Terminal studs have welded
lead
con-
nections;
therefore be extremely
careful
not to
twist
during
removal of nuts.
If
solenoid contacts are slightly burned or dirty,
contacts should be cleaned. When contacts are badly
burned,
burned parts should be replaced.
ASSEMBLE
1. When assembling cover on solenoid, make sure
the terminal studs are properly positioned in cover.
The
cover gasket must be centered under cover to
insure
proper sealing.
2. Secure cover with screws and install nuts on
motor and switch terminals.
STARTER
MOTOR
DISASSEMBLE
1. Disconnect field straps from terminal on
solenoid.
2. Remove through bolts.
3.
Remove commutator end frame, field frame
and
armature from drive housing.
4. Remove overrunning clutch from armature shaft
as follows:
a.
Slide thrust collar (Fig. 6E-1) off end of
armature
shaft.
RETAINER

Armature
and
Overrunning
Clutch
Assembly
b. Slide a standard half-inch pipe coupling or
other metal cylinder of suitable size (an old pin-
ion of suitable size can be used if available)
onto
shaft so end of coupling or cylinder butts against
edge
of retainer (Fig.
6E-2).
Tap end of coupling
with
hammer, driving retainer towards armature
and
off snap
ring.
c. Remove snap ring from
groove
in shaft,
using pliers or other suitable tool. If snap ring is
too badly distorted during removal, it
will
be nec-
essary to use a new one when reassembling clutch.
d.
Slide retainer and clutch from armature
shaft.
