INSPECTION

PROCEDURE

1. INSPECT GENERATOR ROTOR ASSEMBLY

(a) Check the rotor for an open circuit.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

100 A Type 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

If the result is not as specified, replace the generator rotor assembly.

(b) Check if the rotor is grounded.

(1) 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

If the result is not as specified, replace the generator rotor assembly.

If rough or scored, replace the generator rotor assembly.

(d) 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.)

If the diameter is less than the minimum, replace the generator rotor assembly.

2. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

(a) 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.)

If the exposed length is less than the minimum, replace the generator brush holder assembly.

3. INSPECT GENERATOR DRIVE END FRAME BEARING

(a) When rotating the bearing, check that there is no abnormal noise and that it rotates smoothly.

If necessary, replace the generator drive end frame bearing.

4. INSPECT GENERATOR ROTOR BEARING

(a) When rotating the bearing, check that there is no abnormal noise and that it rotates smoothly.

If necessary, replace the generator rotor assembly.
