13. Clearly mark all stator leads to insure proper reconnection. See Wiring Diagram.
14. Disconnect all of the stator winding leads. Note how the leads are routed and connected as well as
the order and placement of leads. See Wiring Diagram.
15. Unwrap leads 3 and 6 from the toroidal current transformer and pull all of the stator leads through
the hole in the blower baffle assembly. All of the leads connected to the stator winding should now
be clear so nothing can bind when the stator is removed later in this procedure. See Wiring
Diagram.
16. Compress the spring clamp and remove the fuel line from the fuel filter/shut-off valve. Pull the line
out of the hole in the engine baffle and then plug the line and the opening in the filter housing to
prevent fuel leakage and contamination.
17. Remove the fuel return line from the fitting in the top of the fuel tank. Plug this line and fitting as
well.
18. Label and disconnect leads as necessary for the removal of the firewall, rout leads thru the firewall.
19. Remove the firewall.
20. Attach the hoist to the lift bale and raise the hoist until it just begins to support some of the weight
of the generator and engine. See Figure F.36.
21. Using a 9/16" deep well socket and a 9/16" open-end wrench, remove the two nuts, lock washers,
bolts and four washers securing the stator frame to the stator support.
22. Raise the hoist to lift the engine and stator assembly just high enough to clear the stator frame
mounting studs.
23. Using a 7/16" nutdriver, remove the ten screws securing the stator support to the machine base.
24. Carefully slide the stator support out of the machine.
25. Using a 5/8" socket, remove the large bolt and centering washer securing the plastic blower to the
rotor shaft. See Figure F.36. It may be necessary to prevent the rotor shaft from turning; a small
pipe wrench can be used for this purpose. DO NOT HOLD THE ROTOR BY THE SLIP RINGS.
26. Label and disconnect leads 230, 5L and 5M from the fuel sender. See Wiring Diagram.
27. Carefully slide the fuel tank assembly out the machine.
28. Position wood blocking to support the engine assembly.
29. Using a 9/16" open-end wrench, remove the four bolts and lock washers securing the stator frame
to the engine.
30. Separate the stator assembly from the engine; in most cases, two screwdrivers can be used to pry
the stator away from the engine. Be careful not to damage the mating surfaces of the engine or
stator frame assembly. If the bearing is binding in the tolerance ring, it may be necessary to use a
gear puller to separate the stator frame from the engine.
31. Carefully slide the stator frame off of the rotor. See Figure F.36.
32. Using the hoist and lifting straps, support the rotor assembly.
33. Remove the screws and disc clamping bars from the rotor coupling disc and remove the rotor.
34. If the rotor is to be replaced, remove the screws, rotor clamping ring and coupling disc from the
rotor hub.
