Starter Inspection and Testing
Armature
1. Using an ohmmeter (Figure 10-10, (1)) check
the commutator for continuity between the
commutator segments. If segments are
electrically open, replace the armature.

Figure 10-10
2. Using an ohmmeter (Figure 10-11, (1)) check
the commutator for continuity between the
commutator and armature coil. If electrical
continuity is measured, replace the armature.

3. Inspect the commutator surface for damage,
dirt and burning. If the commutator surface is
lightly damaged, imperfections may be
corrected with #400 emery cloth or by turning
on a lathe.
4. Inspect the commutator for radial runout by
mounting the commutator on a V-block to
measure runout using a dial indicator
(Figure 10-12).
Commutator radial runout:
• Maximum: 0.05 mm (0.001 in.)

5. If the measured value exceeds the specified
maximum, correct using a lathe if possible or
replace the armature.
6. Measure commutator diameter using calipers
(Figure 10-13). If the measured value is less
than the specified minimum, replace the
armature.
Commutator diameter:
• Standard 36.0 mm (1.41 in.)
• Minimum 35.0 mm (1.37 in.)
