Bench Testing: Rotor
- Measure slip ring outer wear. If worn greater than .04" (1.0 mm) for models equipped with 4-cylinder engine, or .024 (.6 mm) on models equipped with 6-cylinder, replace rotor. See SLIP RING STANDARD DIAMETER & WEAR LIMIT
table. Inspect slip rings for contamination or roughness. Polish with No. 500 or 600 emery paper or crocus cloth.SLIP RING STANDARD DIAMETER & WEAR LIMIT
Application In. (mm) Slip Ring Outer Diameter 4-cylinder Standard 1.063 (27) Wear Limit 1.024 (26) 6-cylinder Standard .894 (22.7) Wear Limit .870 (22.1) - Check continuity between rotor slip rings. If continuity does not exist, replace rotor. Connect ohmmeter between each slip ring and rotor. If continuity exists, replace rotor assembly. Check rotor bearing for noise and ease of rotation when turning. Replace as necessary.
