Starter Inspection (2.0L Engine): Inspection
- Armature (Commutator Diameter) - Inspect
Preconditions
Figure 1
Procedure/Specifications
1. Inspect the armature for wear or damage from contact with the permanent magnet. (Figure 1)
Specifications
Object Specification Armature Not worn or damaged Figure 2
2. Check the commutator (a) surface. If the surface is dirty or burnt, resurface it with an emery cloth or a lathe to the specifications in step 3, or recondition with '500 or '600 sandpaper (b). (Figure 2)
Figure 3
3. Check the commutator.
