Cleaning & Inspection
- Rotor, stator and bearing must not be cleaned with solvent. Clean these components with a clean cloth. Clean remaining components with clean solvent. Inspect bearings for signs of lubricant loss or roughness.
- Inspect rotor shaft bearing area for signs of bearing movement. Inspect all soldered connections on rotor and stator for looseness. Inspect rotor and stator for signs of burned insulation.
- Inspect rotor slip rings for nicks or roughness. Rotor slip rings can be turned down to remove nicks or roughness. Rotor slip rings must not be turned smaller than specification. See ALTERNATOR SPECIFICATIONS table.
- Check brush length. Replace brushes if worn less than .250" (6.35 mm). Replace all damaged components.
NOTE:
High-temperature rectifier and bearings must be used when rebuilding high-temperature alternator. Alternator failure will result if standard components are used.
