Starter Motor: Testing and Inspection
Armature
1. Ground of armature coil
Check continuity between the commutator and the core by using a circuit tester. Replace the armature if there is continuity.
1. Runout of commutator
a. Place the armature on V-blocks, and measure the runout by using a dial indicator.
b. If the runout is at the limit or more, repair by using a lathe or replace the armature
Standard runout: 0.05 mm (0.002 in)
Limit: 0.1 mm (0.004 in)
3. Outer diameter of commutator
Replace the armature it the outer diameter of the commutator is at the wear limit or less.
4. Roughness of commutator surface
If the commutator surface is dirty, wipe it with a cloth; if it is rough, repair by using a lathe or fine sandpaper.
Wear limit: 28.8 mm (1.14 in)
5. Segment groove depth
If the depth of the mold between segments is at the minimum depth or less, undercut the grooves to the standard depth.
Standard depth: 0.5 mm (0.020 in)
