damage. Unclip the lead to the negative battery
cable from the side of the battery tray (if applica-
ble). Detach the carrier tray if necessary by remov-
ing the upper battery carrier tray bolts, and the side

UNIT REPAIR
STARTER MOTOR
Disassembly Procedure
1. Remove the starter. Refer to ”Starter” in this sec-
tion.
2. Remove the starter through–bolts.
3. Remove the commutator end frame and brush
holder assembly.
4. Inspect the brushes, the pop–out springs, and the
brush holders for wear and damage. Replace the
assembly, if needed.
5. Check the armature to see if it turns freely. If the
armature does not turn freely, break down the as-
sembly immediately, starting with Step 14. Other-
wise, give the armature a no–load test.
Notice : Complete the testing in a minimum amount of
time to prevent overheating and damaging the solenoid.
Important : If the specified current draw does not include
the solenoid, deduct from the armature reading the speci-
fied current draw of the solenoid hold–in winding.
6. To begin the no–load test, close the switch and
compare the rpm, the current, and the voltage read-
ings with the specifications. Refer to ”Starter Speci-
fications” in this section. Make disconnections only
with the switch open. Use the test results as fol-
lows:

1) Rated current draw and no–load speed indicate
a normal condition for the starter motor.
2) Low rpm combined with high current draw is an
indication of excessive friction caused by tight,
dirty, or worn bearings; a bent armature shaft;
a shorted armature; or a shorted field coils.
3) Failure to operate with high current draw indi-
cates a direct ground in the terminal or fields,
or ”frozen” bearings.
4) Failure to operate with no current draw indi-
cates an open field circuit, open armature coils,
broken brush springs, worn brushes, high in-
sulation between the commutator bars, or oth-
er causes which would prevent good contact
between the brushes and the commutator.
5) Low, no–load speed and low current indicate
high internal resistance and high current draw,
which usually mean shorted fields.
7. Remove the solenoid assembly screws.
8. Remove the field connector nut. Disconnect the
field connector.

12. Slide the field frame with enclosed armature as-
sembly away from the starter assembly.
13. Remove the shield.
14. Separate the field frame from the armature.
15. Inspect the shaft and the pinion for discoloration,
damage, or wear. Replace, if necessary.
16. Inspect the armature commutator. If the commuta-
tor is rough, it should be turned down. The outside
diameter of the commutator must measure at least
26.9 – 27.1mm (1.059 – 1.067 in.) after it is under-
cut or turned. Do not turn out–of–round commuta-
tors.
17. Inspect the points where the armature conductors
join the commutator bars. Make sure they have a
good connection. A burned commutator bar is usu-
ally evidence of a poor connection.
18. If test equipment is available, check the armature
for short circuits by placing it on a growler, and
holding back a saw blade over the armature core
while the armature is rotated. If the saw blade vi-
brates, replace the armature.
19. Recheck the armature after cleaning between the
commutator bars. If the saw blade vibrates, replace
the armature.

24. Remove the plunger with the boot and the shift le-
ver assembly. Test the solenoid windings, if not
done in Step 11.
Important : The pinion clearance must be correct to pre-
vent the buttons on the shift lever yoke from rubbing on the
clutch collar during the cranking.
25. When the starter motor is disassembled and the
solenoid is replaced, it is necessary to check the
pinion clearance.
26. Disconnect the motor field coil connector from the
solenoid motor terminal and carefully insulate the
connector.
27. Connect one 12–volt battery lead to the solenoid
switch terminal and the other to the starter frame.
28. Flash a jumper lead momentarily from the solenoid
motor terminal to the starter frame, allowing shifting
of the pinion in the cranking position, where it will
remain until the battery is disconnected.
Important : A means for adjusting the pinion clearance is
not provided on the starter motor. If the clearance does not
fall within the limits, check for improper installation and re-
place all worn parts.
29. Push the pinion back as far as possible to take up
any movement, and check the clearance with a
feeler gauge. The clearance should be 0.25 to 3.56
mm (0.01 to 0.14 inch).
Assembly Procedure
1. Install the drive and the pinion stop on the drive-
shaft.
