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 TEST
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 (100 - 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 11volts.
7. Confirm that the maximum amperage is within the specifications and that the starter motor turns smoothly and
freely.
Current : 900A
Speed : 2,800 rpm

REMOVAL
STATATER
1. Disconnect the battery negative cable.
2. Disconnect the starter cable (A) from the B terminal (B) on the solenoid (C), then disconnect the connector (D)
from the S terminal (E).
3.Remove the 2 bolts holding the starter, then remove the starter.
4. Installation is the reverse of removal.
5. Connect the battery negative cable to the battery.
DISASSEMBLY
1.Disconnect the M- terminal (A) on the magnet switch assembly (B).
2.After loosening the 3 screws (A), detach the magnet switch assembly (B).
3.Loosen the through bolts (A).

INSPECTION
ARMATURE INSPECTION AND TEST1. 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.
a. If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips
between the segments.
b. If the commutator run out is not within the service limit, replace the armature.
Commutator runout
Standard (New): 0.02mm (0.0008in.) max
Service limit: 0.05mm (0.0020in.)

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) : 0.5 mm (0.0197 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
Brushes that are worm out, or oil - soaked, should be replaced.
Page 185 of 1575
STARTER BRUSH HOLDER TEST
1.Check that there is no continuity between the (+) brush holder (A) and ( - ) brush holder (B). If there is no 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 it if 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 of it 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.
