| 1. INSPECT GENERATOR CLUTCH PULLEY |
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 generator clutch pulley.
| 2. INSPECT GENERATOR ROTOR ASSEMBLY |
Check the rotor for an open circuit.
Measure the resistance between the slip rings.
- Standard resistance:
Tester connection
| Condition
| Specified condition
|
Slip ring - Slip ring
| Approx. 20°C (68°F)
| 2.3 to 2.7 kΩ
|
If the resistance is not as specified, replace the rotor assembly.
Check the rotor for a short to ground.
Measure the resistance between the slip ring and rotor.
- Standard resistance:
Tester connection
| Condition
| Specified condition
|
Slip ring - Rotor
| -
| 1 MΩ or higher
|
If the resistance is not as specified, replace the rotor assembly.
Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor assembly.
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 rotor assembly.
| 3. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY |
Using vernier calipers, measure the length of the exposed brushes.
- 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.
| 4. INSPECT GENERATOR ROTOR BEARING |
Check that the bearing is not rough or worn.
If necessary, replace the rotor assembly.
| 5. INSPECT GENERATOR DRIVE END FRAME BEARING |
Check that the bearing is not rough or worn.
If necessary, replace the drive end frame bearing.
