Generators & Regulators: Overhaul: Generator: Reassembly

To reassemble, follow the disassembly steps in the reverse order of removal.

NOTE:
  • Never make battery connections with polarities reversed, or battery will be shorted via the diodes. This will cause damage to the diodes.
  • Do not connect generator B terminal to the ground, it is directly connected to the battery. This cable will burn if it is connected to the ground.
  • Ensure to disconnect the positive (+) terminal of the battery when quick-charging battery. Diodes may be damaged due to the abnormal pulse voltage generated by the quick charger.
  • When reassembling the front section to rear section, insert a stiff wire into hole in the rear face of the rear cover from the outboard side to support the brush in raised position. Insert the front section to which rotor is assembled.
  • Reassemble parts carefully to be sure they fit into their original position, paying attention to the insulated portions.
  • Wipe insulating tubes, washers and plates clean and install them in position carefully to avoid getting oil or grease on them.
  1. Using a press with a socket wrench attached, reassemble rotor and rear end cover assembly in the front cover. See Fig 1 .
  2. Install pulley on the rotor. Secure the pulley directly in the vise between two copper plates, and tighten nut to specifications. See TORQUE SPECIFICATIONS  . See Fig 2 .
