Armature Test
- Measure the outer diameter of commutator, and replace with a new one if it is out of limit. See Fig 1
. See STARTER SPECIFICATIONS
.
- Check for continuity between segment and segment. Replace commutator if there is no continuity. See Fig 2
.
- Check for continuity between commutator and shaft. Also, check for continuity between commutator and armature core, armature core and shaft. Replace commutator if there is continuity. See Fig 3
.
- Measure runout of armature core and commutator with a dial gauge. SeeFig 4
. Repair or replace, if it exceeds the limit. See STARTER SPECIFICATIONS
.
- Polish commutator surface with sandpaper #500 to #600 if it is rough. See Fig 5
.
- Measure the depth of insulator in commutator. Replace, if it is below the limit. See Fig 6
. See STARTER SPECIFICATIONS
