ГЕНЕРАТОР (для моделей с номинальным током 100 A) ПРОВЕРКА

INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

1. 

   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.

INSPECT GENERATOR ROTOR ASSEMBLY

1. Check the resistance.

   
   
   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) 1.8 to 2.2 Ω

      Table 1. Text in Illustration

      *1

      Slip Ring

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

   2. 

      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

      Table 2. Text in Illustration

      *1	Slip Ring
      *2	Rotor Core

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

2. 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. 

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

      Standard diameter
      14.2 to 14.8 mm (0.559 to 0.583 in.)

      Minimum diameter
      14.0 mm (0.551 in.)

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

3. 

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

   If the bearing does not rotate smoothly, replace the generator rotor assembly.

INSPECT GENERATOR PULLEY WITH CLUTCH

1. 

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

   Table 3. Text in Illustration

   *a	Free
   *b	Lock

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