STATOR/ROTOR REMOVALAND REPLACEMENT (continued)
19. The wires connected to the solenoid side of
the engine can remain attached, in most
cases.
20. Compress the spring clamp and remove the
fuelline 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.
21. Remove the fuel return line from the fitting in
the top of the fuel tank. Plugthis line and fit-
ting as well.
22. Remove the engine baffle.
23. 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.
24. Remove the two nuts holding the generator
to the support bracket, and the two screws
holding the engine support brackets to the
rubber engine mounts.
25. Raise the hoist to lift the engine and genera-
tor assembly just high enough to clear the
generator mounting studs. Thecenter baffle
will need to be gently pushed forward to pro-
vide clearance between the fan and the
Chopper module. In some cases, the
Chopper module mounting screws may need
to loosened or removed so the chopper mod-
ule can be positioned to provide additional
clearance. Ifthe chopper module screws are
removed, the chopper module will need to be
supported.
26. Rotate the engine and generator assembly
180 degrees and line up the engine mounting
bracket to the rubber engine mounts. Be
careful that the wiring still attached to the
engine does not get damaged. Disconnect
additional engine wiring, and/or remove addi-
tional cable ties if necessary.
27. Replace the screws, which had been
removed from those mounts, and tighten.
28. Use wooden blocks or other means to
securely support the flywheel end of the
engine, and remove the hoist from the lift
bale.
29. The generator is now in position for easy
removal.
30. Remove the plastic blower and flat washer
from the rotor shaft by turning the blower
counter-clockwise. 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.
31. Use the hoist, along with lifting straps or
chains to support the generator stator
assembly, and then remove the screws
attaching it to the engine.
32. 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
surfacesof the engine or stator frame assem-
bly. 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.
33.Carefullyside the stator assembly off the rotor.
