6. Remove generator rotor assy

  1.  remove the washer from the rotor.
  2.  remove the rotor from drive end frame.

7. Inspect generator regulator assy

  1. Using an ohmmeter, check the continuity between terminals f and b.

Standard

: when the positive and negative poles between terminals f and b are exchanged, there is continuity in one way but no continuity in another way.

  1. Using an ohmmeter, check the continuity between terminals f and e.

Standard

: when the positive and negative poles between terminals f and e are exchanged, there is continuity in one way but no continuity in another way.

8. Inspect generator regulator assy

  1. Using an ohmmeter, check that there is continuity between the slip rings.

    Standard resistance: 2.1 – 2.5 W at 20 c (68 f)

  1. Using an ohmmeter, check that there is no continuity between the slip ring and rotor.

  1. Using a vernier calipers, measure the slip ring diameter.

    Standard diameter: 14.2 – 14.4 Mm (0.559 – 0.567 In.) Minimum diameter: 12.8 Mm (0.504 In.)

9. Inspect brush

  1. Using a vernier calipers, measure the exposed brush length.

    Standard exposed length: 9.5 – 11.5 Mm (0.374 – 0.453 In.) Minimum exposed length: 1.5 Mm (0.059 In.)

10. Install generator rotor assy

  1. Install the rotor to the drive end frame.
  2.  install the washer on the rotor.

  1. Using a socket wrench 29 and press, slowly press in the rectifier end frame.

  1. Install the cord clip and 4 nuts.

    Torque:
    nut a 4.5 Nvm (46 Kgf·cm, 40 in.Vlbf) nut b 5.4 Nvm (55 Kgf·cm, 48 in.Vlbf)

11. Install generator holder w/rectifier

  1.  install the holder w/ rectifier with 4 screws.

    Torque: 2.9 Nvm (30 Kgf·cm, 26 in.Vlbf)

12. Install generator regulator assy

  1.  install the regulator with the 3 screw.

    Torque: 2.0 Nvm (20 Kgf·cm, 18 in.Vlbf)

13. Install generator brush holder assy

  1. Place the plate seal on the brush holder.
  2. install the brush holder with the 2 screws.

    Torque: 2.0 Nvm (20 Kgf·cm, 18 in.Vlbf)

Notice

: pay attention to the holder installation direction.

  1.  place the brush cover on the brush holder.
  2.  install the rear end cover with the 2 nuts.

    Torque: 4.4 Nvm (45 Kgf·cm, 39 in.Vlbf)

  3.  install the terminal plate with the screw and nut.

    Torque:
    bolt 3.9 Nvm (40 Kgf·cm, 35 in.Vlbf) nut 4.4 Nvm (45 Kgf·cm, 39 in.Vlbf)

  4.  install the terminal insulator withe the nut.

    Torque: 4.1 Nvm (42 Kgf·cm, 36 in.Vlbf)
