If the result is not as specified, replace the generator pulley with clutch.
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.
3. INSPECT GENERATOR ROTOR ASSEMBLY |
Check that the generator rotor bearing is not rough or worn.
If necessary, replace the generator rotor assembly.
Check the resistance.
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
*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 MΩ 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.
