INSPECTION

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 and 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

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

(c) Check that the slip rings are not rough or scored.

If rough or scored, replace the 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 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 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 bearing.

4. REPLACE GENERATOR DRIVE END FRAME BEARING

(a) Remove the 4 screws and retainer plate.

(b) Using SST and a hammer, tap out the bearing.
