GENERATOR INSPECTION


  1. INSPECT GENERATOR CLUTCH PULLEY


    1. A017B4VE01

      Hold the center of the pulley, and confirm that the outer ring turns counterclockwise and does not turn clockwise.

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

  2. INSPECT GENERATOR DRIVE END FRAME BEARING


    1. A017DN8

      Check that the bearing is not rough or worn.

      OK
      The bearing rotates smoothly.

      If the bearing does not rotate smoothly, replace the bearing.

  3. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A017FZLE01

      Using vernier calipers, measure the length of the exposed brushes.

      Standard exposed length
      9.5 to 11.5 mm (0.374 to 0.453 in.)
      Minimum exposed length
      4.5 mm (0.177 in.)

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

  4. INSPECT GENERATOR ROTOR ASSEMBLY


    1. A017CSZE02

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

      If necessary, replace the generator rotor assembly.

    2. A017E6EE08

      Check the generator rotor for an open circuit.


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

        Standard resistance
        w/o Rear heater assembly and multi-information display
        Condition Specified Condition
        Approx. 20°C (68°F) 2.3 to 2.7 Ω (130 A type)
        w/ Rear heater assembly or multi-information display
        Condition Specified Condition
        Approx. 20°C (68°F) 1.5 to 1.9 Ω (150 A type)

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

    3. A017DLME01

      Check the rotor for a short to ground.


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

        Standard resistance
        Tester Condition Specified Condition
        Slip ring - Rotor 1 MΩ or higher

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

    4. A017D4WE01

      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 generator rotor assembly.
