Charging Systems: Alternators: Overhaul: Disassembly

Remove drive and ventilation components from rotor shaft. Remove brush holder (with brushes) by backing out its mounting screw on diode end head. Remove Woodruff key on shaft.
Unscrew nuts of the four through bolts, remove drive end frame and rotor. Before removing stator, unscrew from inside (of housing), three nuts securing stator winding phase ends to diode ends. Remove stator.
To disassemble diode end frame, unscrew the nut of terminal "30". The frame with negative diodes and the support with positive diodes will thus be separated.
