Zusammenfassung:PURPOSE:To enable only a piston from being taken out outside at a low disassembly level by suspending a piston and a connection rod connected to each other, thereafter fixing the rod on the side of an engine, and then transferring only the piston outside of the engine after it is extracted. CONSTITUTION:After a cylinder head is released, a piston 9 and a connection rod 18 connected by means of a pin 8 is suspended. Next, under a state that portions near small end positions of the piston 9 and the connection rod 8 are extracted from the upper and of opening of a cylinder 6, a device 10 is set in the vicinity of the small end portions thereof. Then, the positions of the piston 9 and the rod 18 with respect to the piston pin 8 are fixed. Further, the piston 9 and the rod 18 is separated from each other by extruding the pin 8, and only the piston 9 is carried out outside of an engine, with the rod, which is fixed by the device 10 engaged with the cylinder 6 at the position, remaining inside the cylinder 6.
