GENERATOR INSPECTION


  1. INSPECT GENERATOR WITH CLUTCH PULLEY (w/ CLUTCH PULLEY)


    1. A003CQIE01

      When rotating the generator pulley, check that it turns counterclockwise and does not turn clockwise.

  2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A003B4TE01

      Using vernier calipers, measure the brush length.

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

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

  3. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A003EQ8

      Check that the generator rotor bearing is not rough or worn.

      If necessary, replace the generator rotor.

    2. A003BSNE01

      Check the rotor for open circuit.


      1. Using an ohmmeter, measure the resistance between the slip rings.

        Standard resistance
        2.3 to 2.7 Ω at 20°C (68°F)

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

    3. A003D0ME01

      Check the rotor for a short circuit.


      1. Using an ohmmeter, measure the resistance between each slip ring and rotor.

        Standard resistance
        1 MΩ or higher

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

    4. A003C1RE01

      Using vernier calipers, 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.
