c. Remove the rotor assembly by striking the side
of the rotor repeatedly with a soft-faced
hammer
to loosen it from the tapered
crankshaft fitting. See Figure 8-9. Rotate the
rotor and strike it on alternate sides. Set the
rotor assembly aside.
9. Remove the four bolts securing the adapter to the
engine. See Figure 8-10. Remove the generator
adapter.
8.2 Reassembly
1. Reinstall the generator adapter onto the engine.
a. Attach the generator adapter and alternator
adapter guard to the engine using four
7/16-14 x 1.0 hex cap bolts and washers.
b. Torque the bolts to 28 ft. lb. (38 Nm). See
Figure 8-10.
2. Install the rotor. See Figure 8-9.
a. Apply a small amount of antisieze compound to
the end of the engine crankshaft for rotor
assembly installation.
b. Install the rotor onto the engine crankshaft.
c. Thread the thrubolt through the actuator and
rotor into the crankshaft. Do not tighten the
thrubolt.
3. Install the stator and end bracket.
a. Install the stator assembly around the rotor.
Align the stator so that the alternator frame
vibromount points down toward the generator
skid. See Figure 8-11.
b. Route the leads connected to the alternator end
bracket through the opening in the base of the
alternator frame.
c. Place the end bracket onto the stator assembly.
align the overbolt holes with the holes in the
generator adaptor.
d. Thread the four overbolts with centering
washers through the end bracket and into the
generator adapter. Position the centering tab of
each washer in the slot on the end bracket. Do
not final tighten the overbolts.
4. Secure the generator set to the skid.
a. Raise the alternator end of the generator set
and remove the block of wood from beneath the
rear of the engine.
