3.
Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature.
Remove the starter (see page EE-25).
Disassemble the starter as shown at the beginning of this procedure.
Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature.
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 runout is not within the service limit, replace the armature.
Commutator Runout
Standard (New) : 0.02mm (0.001 in.) max.
Service limit : 0.05mm (0.002 in.)
Check for continuity between the segments of the commutator. If an open circuit exists between any segments, replace the armature.
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.
Slide the overrunning clutch along the shaft.
Replace it if does not slide smoothly.
Rotate the overrunning clutch (A) both ways.
Does it lock in one direction and rotate smoothly in reverse? If it does not lock in either direction or it locks in both directions, replace it.
If the starter driver gear (B) 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.
