### Disassembly Procedure

Notice: Do not pry against the stator or the slip ring end frame during generator disassembly. Damage to the generator may result.

1. Make scribe marks on the following components in order to ease in assembly:

• | The slip ring end frame

• | The drive end frame

2. Remove the 4 through bolts.

Notice: On models with a slip ring end ball bearing on the rotor shaft, this bearing must be replaced with a new bearing any time the two halves of the generator are separated, if not replaced, the bearing may bind and fall due to distortion of its outer tolerance rings. This does not apply to roller-type slip ring end frame bearings.

3. Separate the slip ring end frame and the drive end frame.
4. Remove the nuts holding the stator to the heat sink.
5. Remove the stator from the slip ring end frame.
6. Unsolder the following connections to the voltage regulator:

• | The connector strap

• | The brush holder

7. Remove the brush holder insulator screw.
8. Remove the voltage regulator screw.
9. Remove the following components from the slip ring end frame:

• | The voltage regulator

• | The brush holder with the dust shield

10. Remove the following components from the brush holder:

• | The brushes

• | The dust shield

11. Clean the brushes with a dry soft cloth.
12. Remove the rectifier bridge and the capacitor as a unit:

• | Remove the bolts.

• | Remove the washers.

• | Disconnect the leads.

• | Remove the bridge and capacitor assembly.

13. Remove the slip ring end frame bearing.
14. Remove the following from the drive end frame:

• | The nut

• | The washer

• | The pulley

• | The fan collar

• | The fan

• | The outside collar

• | The rotor

15. Remove the inside collar from the rotor.

### Inspection Procedure

1. Refer to the Generator Component Test for Generator Diagnosis.
2. Inspect the drive end bearing. If the bearing is rough or worn, replace the generator drive end frame assembly.
3. Inspect the slip ring end bearing. If the bearing is rough or worn, replace with a new bearing.
4. Inspect the rotor for grounds (1), opens (2), or shorts (2).
5. Inspect the stator for grounds.
7. Inspect the rectifier bridge for continuity.
