BENCH TESTING
ARMATURE TEST
1. Remove the starter. See STARTER under REMOVAL & INSTALLATION.
2. Disassemble starter. See STARTER under OVERHAUL.
3. Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or
damage, replace the armature. See Fig. 9 .
4. Check the commutator (A) surface. If the surface is dirty or burnt, resurface with emery cloth or a lathe
within specifications, or recondition with # 500 or # 600 sandpaper (B). See Fig. 10 .
5. Check the commutator diameter. See Fig. 11 . See STARTER SPECIFICATIONS . If the diameter is
below the service limit, replace the armature.
6. Measure the commutator runout. See Fig. 12 . See STARTER SPECIFICATIONS . 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.
7. 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). See Fig. 13 .
8. Check for continuity between the segments of the commutator. See Fig. 14 . If an open circuit exists
between any segments, replace the armature.
9. Place the armature (A) on an armature tester (B). Hold a hacksaw blade (C) on the armature core. See
Fig. 15 . If the blade is attracted to the core or vibrates while the core is turned, the armature is shorted.
Replace the armature.
10. 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. See
Fig. 16 .
