See Graphic: wc_gr000940
Capacitor
5.15.1 Remove the two end cover screws (h) and the end cover (g).
5.15.2 Disconnect the leads from the capacitor (j), cut the nylon tie wrap, and
remove the capacitor mounting screw.
Stator
5.15.1 Remove the control panel, unscrew the ground wire (m) and unplug
the stator wire (n) from the back of the panel.
5.15.2 Remove the shaft securing nut (e).
5.15.3 Remove the four nuts (l) securing the generator frame (k) to the engine
adapter flange.
5.15.4 Remove the two bolts and nuts that secure the stator (k) to the shock
mount bracket.
5.15.5 With a block of wood and a mallet, tap stator frame away from the
engine. Withdraw stator frame assembly (k) over the rotor (a) carefully
to avoid damage to windings in the stator or rotor.
Note: If the rotor comes out with the stator, skip step 6.
5.15.6 Support the rotor weight with a sling or place a block between the rotor
and base.
Rotor
Rotor (a) removed with stator:
5.15.1 Place stator on flat surface with bearing (d) end up. Elevate the stator
(k) by placing two blocks of wood on the edge of the stator frame to
allow the rotor to drop.
5.15.2 Partially screw one of the frame mounting bolts into the bearing and
tap screw with a mallet. The rotor should drop out of the stator.
Rotor (a) still attached to the engine:
5.15.1 Remove stator per instructions above.
5.15.1 Release the rotor (a) from the engine shaft by supporting rotor in one
hand and with a mallet, striking firmly on a pole face.
Diode and/or Varistor
5.15.1 Unsolder leads from the diodes (c) and (f) and unscrew diode stud.
5.15.2 Unsolder varistor lead from the solder tag on the diode stud.
5.15.3 Remove the silicon sealant supporting the varistor from the diode
bracket (b).
