GENERATOR INSPECTION


  1. INSPECT GENERATOR WITH CLUTCH PULLEY


    1. A01DNJV

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

      *1 Length

      Using a vernier caliper, measure the brush length.

      Standard length
      9.5 mm to 11.5 mm (0.374 to 0.453 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. A01DS7R

      Inspect that the bearing is not rough or worn.

      If necessary, replace the generator rotor assembly.

      *1 Slip Ring

      Check the rotor for an open circuit.


      1. 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) 2.3 to 2.7 Ω

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

      *1 Slip Ring
      *2 Rotor Core

      Check if the rotor is grounded.


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

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

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

    4. A01DUHR

      Using a vernier caliper, measure each 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 either diameter is less than the minimum, replace the rotor.
