INSPECTION

PROCEDURE

1. INSPECT GENERATOR PULLEY WITH CLUTCH

(a) Hold the center of the pulley, and confirm that the outer ring turns counterclockwise and does not turn clockwise.

*2	Lock

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

2. INSPECT GENERATOR DRIVE END FRAME BEARING

(a) Check that the bearing is not rough or worn and that it rotates smoothly.

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 brush length.

Length

Standard length:

9.5 to 11.5 mm (0.374 to 0.453 in.)

Minimum length:

4.5 mm (0.177 in.)

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

4. INSPECT GENERATOR ROTOR ASSEMBLY

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

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

(b) Check the rotor for an open circuit.

*2	Ohmmeter

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
130 A	Approx. 20°C (68°F)	2.3 to 2.7 Ω
150 A	Approx. 20°C (68°F)	1.5 to 1.9 Ω

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

*1	Slip Ring
*2	Ohmmeter
*3	Rotor

(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.

(d) Check the slip ring diameter.

(1) Using a vernier caliper, measure the diameter of each slip ring.

Diameter

Standard diameter:

14.2 to 14.4 mm (0.559 to 0.567 in.)

Minimum diameter:

14 mm (0.551 in.)

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