  3. Remove 1 screw with plastic insulator, holding diode trio to brush holder. Remove diode trio. Remove screws securing regulator and brush holder. Remove indicator lamp resistor, brush holder, and regulator.
  4. Remove rectifier bridge by removing screw with washer, screw at capacitor lead, and nut/washer from "BAT" terminal stud. Remove insulator and "BAT" terminal stud. Remove screw securing capacitor to end of frame.
  5. To remove rotor from drive end frame, install rotor in vise, but only tight enough to remove shaft nut, washer, pulley, fan, and collar. Separate end frame from rotor.
