Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cleaning & Inspection
Wash all metal parts except stator and rotor assemblies. Clean bearings and inspect for sealing, pitting or roughness. Slip rings may be cleaned with 400 grain polishing cloth (rotate shaft while cleaning to prevent flat spots on rings). Slip ring maximum out of round limit is 0.001". Turn slip rings in a lathe to correct and remove only sufficient material to make rings smooth and round. Polish with 400 grain polishing cloth.
Inspect brushes for wear and if worn halfway, replace. Inspect brush springs for distortion or weakening.
