2.3 Disassembly/Reassembly of Generator Main Unit and Connection
of Generator Main Unit and Engine
2.3.1 Disassembly of generator main unit
 The generator main unit is unilaterally mounted and the clearance is small, so it must
be handled with extreme care to avoid the possibility of damage to the rotor or stator.
 Use hoisting equipment of sufficient capacity when it is necessary to lift up the engine
and the generator main unit.
