Armature Test
- Remove the starter.
- Disassemble the starter.
- Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature. See Fig 1.
- Check the commutator surface "A". See Fig 2. If surface "A" is dirty or burnt, resurface with emery cloth or a lathe, If surface "B" is dirty or burnt, recondition with #500 or #600 sandpaper.
- Check the commutator diameter. See Fig 3. See STARTER SPECIFICATIONS . If the diameter is below the service limit, replace the armature.
- Measure the commutator runout. See Fig 4. 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 run out is not within the service limit, replace the armature.
- Check the mica depth "A". See Fig 5. See STARTER SPECIFICATIONS . If the mica "B" is too high, undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica "C" between commutator segments. The undercut should not be too shallow, too narrow or v-shaped "D".
