Reassembly
1.
Reassemble in the reverse order of disassembly.
Inspection
Starter Solenoid Inspection
1.
Disconnect the lead wire from the M-terminal of solenoid switch.
2.
Connect the battery as shown. If the starter pinion pops out, it is working properly.
•
To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
3.
Disconnect the battery from the M terminal.
If the pinion does not retract, the hold-in coil is working properly.
•
To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
4.
Disconnect the battery also from the body. If the pinion retracts immediately, it is working properly.
•
To avoid damaging the starter, do not leave the battery connected for more than 10 seconds.
Free Running Inspection
1.
Place the starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to starter motor as follows.
2.
Connect a test ammeter (150-ampere scale) and carbon pile rheostats shown is the illustration.
3.
Connect a voltmeter (15-volt scale) across starter motor.
4.
Rotate carbon pile to the off position.
5.
Connect the battery cable from battery''s negative post to the starter motor body.
6.
Adjust until battery voltage shown on the voltmeter reads 11 volts.
7.
Confirm that the maximum amperage is within the specifications and that the starter motor turns smoothly and freely.

Armature Inspection And Test
1.
Remove the starter.
2.
Disassemble the starter as shown at the beginning of this procedure.
3.
Inspect the armature for wear or damage from contact with the
permanent magnet. If there is wear or damage, replace the armature.
4.
Check the commutator (A) surface. If the surface is dirty or
burnt, resurface with emery cloth or a lathe within the following
specifications, or recondition with #500 or #600 sandpaper (B).
5.
Measure the commutator (A) runout.
•
If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments.
•
If the commutator run out is not within the service limit, replace the armature.
Commutator runout
Standard (New): 0.05mm (0.0019in.) max
Service limit: 0.08mm (0.0031in.)
6.
Check the mica depth (A). If the mica is too high (B),
undercut the mica with a hacksaw blade to the proper depth. Cut away all
the mica (C) between the commutator segments. The undercut should not
be too shallow, too narrow, or v-shaped (D).
Commutator mica depth
Standard (New) : 0.8 mm (0.314 in.)
Limit : 0.2mm (0.0079 in.)
7.
Check for continuity between the segments of the commutator.
If an open circuit exists between any segments, replace the armature.
8.
Check with an ohmmeter that no continuity exists between the
commutator (A) and armature coil core (B), and between the commutator
and armature shaft (C). If continuity exists, replace the armature.
Inspect Starter Brush
Any worn out or oil-soaked brushes should be replaced.
Starter Brush Holder Test
1.
Check that there is no continuity between the (+) brush
holder (A) and (-) plate (B). If there is continuity, replace the brush
holder assembly.
2.
Pry back each brush spring (A) with a screwdriver, then
position the brush (B) about halfway out of its holder, and release the
spring to hold it there.
3.
Install the armature in the housing, and install the brush
holder. Next, pry back each brush spring again, and push the brush down
until it seats against the commutator, then release the spring against
the end of the brush.
To seat new brushes, slip a strip of #500 or #600 sandpaper,
with the grit side up, between the commutator and each brush, and
smoothly rotate the armature. The contact surface of the brushes will be
sanded to the same contour as the commutator.
Inspect Overrunning Clutch
1.
Slide the overrunning clutch along the shaft.
Replace if it does not slide smoothly.
2.
Rotate the overrunning clutch both ways.
Does it lock in one direction and rotate smoothly in reverse?
If it does not lock in either direction or locks in both directions,
replace it.
3.
If the starter drive gear is worn or damaged, replace the overrunning clutch assembly. (The gear is not available separately.)
Check the condition of the flywheel or torque converter ring gear if the starter drive gear teeth are damaged.
Cleaning
1.
Do not immerse parts in cleaning solvent.
Immersing the yoke assembly and/or armature will damage the insulation wipe these parts with a cloth only.
2.
Do not immerse the drive unit in cleaning solvent.
The overrun clutch is pre-lubricated at the factory and solvent will wash lubrication from the clutch.
3.
The drive unit may be cleaned with a brush moistened with cleaning solvent and wiped dry with a cloth.
Inspection
1.
Turn ignition switch OFF and disconnect the negative (-) battery terminal.
2.
Remove the fuse box cover.
3.
Remove the starter relay (A).
4.
Check for continuity between ...
