LUCAS Alternators: Overhaul: Disassembly
- Remove end cover, and note wire positions and color. Remove capacitor screw, rectifier lead, and capacitor. Remove surge protection diode lead from brush box and rectifier. Remove diode retaining screw and diode.
- Note arrangement of regulator brush box and other connections. Remove screw, and lift out regulator. Remove brush box. Brushes, slip ring, and rotor can now be checked.
- To remove rectifier, unsolder stator cable ends. Remove terminal nut and damper blocks. Loosen nuts and remove rectifier.NOTE: Position of all washers, spacers, and insulators must be noted for proper assembly.
- Mark position of stator ring in end brackets to ensure correct reassembly. Remove through bolts from alternator frame, and carefully slip end bracket and stator off of rotor. It may be necessary to tap lightly on an extractor or tube placed against outer bearing journal to separate rotor from end bracket.
- Complete disassembly, if required, by removing fan, pulley, Woodruff key, and fan spacer. Press rotor from drive end bracket, and remove bearing from bracket. Replace as necessary.
