GENERATOR(for 100A Type) DISASSEMBLY

PROCEDURE


  1. REMOVE GENERATOR PULLEY


    1. Mount the generator assembly in the vise between aluminum plates.

    2. B003K8LC01
      *a Hold
      B003R2S Turn

      Install SST 1-A to the pulley shaft.

      SST
      09820-63011   ( 09820-06010, 09820-06021 )
      SST 1-A and B 09820-06010
      SST 2 09820-06021

    3. Install SST 1-B to SST 1-A.

    4. Hold SST 1-A with a torque wrench and turn SST 1-B clockwise with the specified torque.

      Torque:
      39 N*m  { 398 kgf*cm, 29 ft.*lbf }

      Note

      Make sure that SST is secured to the generator rotor shaft.

    5. B003MUSC01
      B003R2S Insert

      Install SST 2 and attach it to the pulley nut.

    6. B003RTZC01
      *a Hold
      B003R2S Turn

      To loosen the pulley nut, turn SST 1-A as shown in the illustration.

      Note

      To prevent damage to the generator rotor shaft, do not loosen the pulley nut more than one-half of a turn.

    7. Remove SST 2 from the generator assembly.

    8. B003K3GC01
      *a Hold
      B003R2S Turn

      Turn SST 1-B as shown in the illustration and remove SST 1-A and B.

    9. Remove the pulley nut and generator pulley.

    10. Remove the generator assembly from the vise.

  2. REMOVE GENERATOR REAR END COVER


    1. B003PWF

      Place the generator assembly on the generator pulley.

    2. Remove the 3 bolts and generator rear end cover from the generator coil assembly.

  3. REMOVE TERMINAL INSULATOR


    1. B003QMD

      Remove the terminal insulator from the generator coil assembly.

  4. REMOVE GENERATOR BRUSH HOLDER ASSEMBLY


    1. B003PER

      Remove the 2 screws and generator brush holder assembly from the generator coil assembly.

  5. REMOVE GENERATOR COIL ASSEMBLY


    1. B003KU1

      Remove the 4 through bolts.

    2. B003RFYC01
      *a Hold
      B003R2S Turn

      Using SST, remove the generator coil assembly.

      SST
      09950-40011   ( 09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04071, 09957-04010, 09958-04011 )

  6. REMOVE GENERATOR BEARING COVER PACKING


    1. B003LFS

      Remove the generator bearing cover packing.

      Note

      If the generator bearing cover packing breaks, remove all broken pieces.

      Tech Tips

      The generator bearing cover packing may be installed on the generator rotor assembly.

  7. REMOVE GENERATOR ROTOR ASSEMBLY


    1. Remove the generator rotor assembly from the generator drive end frame.

  8. INSPECT GENERATOR DRIVE END FRAME BEARING

    B003NU6

    1. Check that the generator drive end frame bearing is not rough or worn and that it rotates smoothly.

      If necessary, replace the generator drive end frame bearing.

  9. REMOVE GENERATOR DRIVE END FRAME BEARING


    1. B003RUL

      Remove the 4 screws and retainer plate from the generator drive end frame.

    2. B003NKBN01

      Using SST and a hammer, tap out the generator drive end frame bearing from the generator drive end frame.
