Illus 87 Disassembling Generator

1. End cover and brushes have already been removed for previous checking and testing.

2. Disconnect field wires. Closely observe how field coil wires are arranged to keep them in the clear so they will not be damaged by armature. One is pulled between generator frame and frame end screw, and one is brought over the outside of aluminum frame end. Also, excess slack is avoided by winding wires together, where they cross at brush holders. The arrangement of wires shown in Illus. 88 applies to three brush type generator only, but method of winding wires together to keep them in the clear also applies to two brush type generator. Note this arrangement and arrange wires in the same manner when reassembling.

3. Standard Generator—remove pin from drive gear; remove gear, spring and oil deflector (1, 2, 3 and 4).

Radio (Two Brush) or (Three Brush) Generator —remove pin from oil centrifuge or clutch spring collar; remove oil centrifuge or clutch spring collar, spring, gear, clutch and oil deflector (1, 2, or 2D, 3, 2B, 2C, and 4).

4. Clamp armature shaft in copper-faced vise jaws with generator in upright position.

5. Take out three end screws and remove outer grease retainer, gasket and third brush holder, or generator end plate (50, 51, 52 and 53).

6. Remove armature shaft nut and lock washer (46) and (47).

7. Remove bearing housing, gasket, bearing and inner grease retainer (40, 41, 42 and 45).
