GENERATOR (for 130 A, 150 A Type) - INSPECTION
| 1. INSPECT GENERATOR ROTOR ASSEMBLY |
Check the resistance.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
for 130 A Type Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 2.3 to 2.7 Ω for 150 A Type Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 1.5 to 1.9 Ω
| *1 | Slip Ring |
If the result is not as specified, replace the generator rotor assembly.
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 kΩ or higher
| *1 | Slip Ring |
| *2 | Rotor Core |
If the result is not as specified, replace the generator rotor assembly.
Using a vernier caliper, measure the slip ring diameter.
- Standard diameter:
- 14.2 to 14.8 mm (0.559 to 0.583 in.)
- Minimum diameter:
- 14.0 mm (0.551 in.)
| *1 | Diameter |
If the diameter is less than the minimum, replace the generator rotor assembly.
Check that the generator rotor bearing is not rough or worn.
If necessary, replace the generator rotor assembly.
| 2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY |
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.)
| *1 | Length |
If the brush length is less than the minimum, replace the generator brush holder assembly.
