ГЕНЕРАТОР ПРОВЕРКА

PROCEDURE


  1. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY


    1. A00YUSH

      Using a vernier caliper, measure the brush length.

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

  2. INSPECT GENERATOR ROTOR ASSEMBLY


    1. Check the resistance.


      1. A00YXLEC02
        *1 Slip Ring

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        Slip ring - Slip ring 20°C (68°F) 1.5 to 1.9 Ω

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

      2. A00YW8ZC02
        *1 Slip Ring
        *2 Rotor Core

        Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        Slip ring - Rotor core Always 10 MΩ or higher

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

    2. A00YWD4

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

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

    3. Check each slip ring.


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

        If rough or scored, replace the generator rotor assembly.

      2. A00YUVX

        Using a vernier caliper, measure the diameter of the slip rings.

        Standard diameter
        14.2 to 14.8 mm (0.560 to 0.582 in.)
        Minimum diameter
        14.0 mm (0.551 in.)

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

  3. INSPECT GENERATOR PULLEY WITH CLUTCH


    1. A00YWNZC02
      *a Free
      *b Lock

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

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