The job for today was to separate the generator part from the engine part.  The kids undid all the bolts on the isolation mounts, the stator assembly, the rotor, and flywheel housing.  They also removed the engine wiring, alternator belt, and some of the hoses.  Grownups were needed to take the bolts off the flywheel with an impact wrench and to physically move the (really, really) heavy stuff out of the way.
