Generator -- Inspection |
| 1. INSPECT GENERATOR DRIVE END FRAME BEARING |
Rotate the bearing and check that there is no abnormal noise and that it rotates smoothly.
If necessary, replace the bearing (Click here).
 |
| 2. INSPECT GENERATOR ROTOR ASSEMBLY |
Check the rotor for an open circuit.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
130 A Type Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 2.3 to 2.7 Ω 150 A Type Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 1.5 to 1.9 Ω 180 A Type Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 1.36 to 1.76 Ω
 |
Check if the rotor is grounded.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Slip ring - Rotor Always 10 kΩ or higher
 |
Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor assembly.
Using a vernier caliper, 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.)
 |
| 3. INSPECT GENERATOR ROTOR BEARING |
Rotate the bearing and check that there is no abnormal noise and that it rotates smoothly.
If necessary, replace the generator rotor.
 |
| 4. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY |
Using a vernier caliper, measure the exposed brush length.
- Standard exposed length:
- 10.5 mm (0.413 in.)
- Minimum exposed length:
- 4.5 mm (0.177 in.)
