GENERATOR INSPECTION


  1. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A01E1PVE01

      Using a vernier caliper, measure the brush length.

      Standard length
      10.5 mm (0.413 in.)
      Minimum length
      4.5 mm (0.177 in.)

      If the brush length is less than the minimum, replace the brush holder assembly.

  2. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A01E2CF

      Check that the bearing is not rough or worn, and that it rotates smoothly.

      If necessary, replace the rotor assembly.

    2. Check the resistance.


      1. A01E1WQE01

        Measure the resistance between the slip rings.

        Standard resistance
        1.85 to 2.25 Ω at 20°C (68°F)

        If the result is not as specified, replace the rotor assembly.

      2. A01DYC2E01

        Measure the resistance between the slip ring and rotor core.

        Standard resistance
        10 kΩ or higher

        If the result is not as specified, replace the rotor assembly.

    3. Check each slip ring.


      1. Check that the slip rings are not rough or scored.

        If rough or scored, replace the rotor assembly.

      2. A01DZO0E01

        Using a vernier caliper, measure the slip ring diameter.

        Standard diameter
        14.2 to 14.4 mm (0.559 to 0.567 in.)
        Minimum diameter
        14.0 mm (0.551 in.)

        If the diameter is less than the minimum, replace the rotor assembly.
