INSPECTION

PROCEDURE

1. INSPECT GENERATOR CLUTCH PULLEY

(a) Hold the generator rotor using SST, and turn the clutch pulley clockwise to check that the outer ring locks.

SST: 09820-63021

*1	Free
*2	Lock

If the result is not as specified, replace the clutch pulley.

2. INSPECT GENERATOR DRIVE END FRAME BEARING

(a) Check that the bearing is not rough or worn.

OK:

The bearing rotates smoothly.

If the bearing does not rotate smoothly, replace the bearing.

3. INSPECT GENERATOR BRUSH HOLDER ASSEMBLY

(a) Using a vernier caliper, measure the length of the exposed brushes.

Length

Standard exposed brush length:

9.5 to 11.5 mm (0.375 to 0.452 in.)

Minimum exposed brush length:

4.5 mm (0.178 in.)

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

4. INSPECT GENERATOR ROTOR ASSEMBLY

(a) Check that the generator rotor bearing is not rough or worn.

If necessary, replace the generator rotor assembly.

(b) Check the generator rotor for an open circuit.

*1	Slip Ring
*2	Ohmmeter

(1) Using an ohmmeter, measure the resistance between the slip rings.

Standard Resistance:

Condition		Specified Condition
Approx. 20°C (68°F)	except 150 A	2.3 to 2.7 Ω
Approx. 20°C (68°F)	for 150 A	1.5 to 1.9 Ω

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

*1	Slip Ring
*2	Rotor
*3	Ohmmeter

(1) Using an ohmmeter, measure the resistance between the slip ring and rotor.

Standard Resistance:

Tester Condition	Specified Condition
Slip ring - Rotor	1 MΩ or higher

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

(d) Using a vernier caliper, measure the slip ring diameter.

Diameter

Standard diameter:

14.2 to 14.4 mm (0.560 to 0.566 in.)

Minimum diameter:

14.0 mm (0.552 in.)

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