4. Remove starting motor mounting screws and
remove starting motor with cable and solenoid wire
loom.

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 f i e l d straps f r o m 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
F i g . 6E-1 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.
