GENERATOR (for DENSO Made) INSPECTION


  1. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A01DY3KE02

      Check the rotor for an open circuit.


      1. 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. A01E0C0E02

      Check if the rotor is grounded.


      1. Measure the resistance between each slip ring and the rotor.

        Standard resistance
        10 kΩ or higher

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

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

      If rough or scored, replace the rotor assembly.

    4. A01DZO0E01

      Using a vernier caliper, measure the diameter of each slip ring.

      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.

  2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

    A01E16ZE02

    1. Using a vernier caliper, measure the exposed brush length.

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

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

  3. INSPECT GENERATOR DRIVE END FRAME BEARING


    1. A01DW5P

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

      If necessary, replace the generator drive end frame bearing.

  4. INSPECT GENERATOR ROTOR BEARING


    1. A01E2CF

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

      If necessary, replace the generator rotor assembly.

  5. INSPECT GENERATOR PULLEY WITH CLUTCH


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

      If the result is not as specified, replace the generator pulley with clutch.
