TOOL FOR ASSEMBLY AND DISASSEMBLY OF TURBINE DEVICE, AND METHOD OF ASSEMBLY AND DISASSEMBLY OF TURBINE DEVICE

An easily-manufactured simple disassembly/reassembly jig is provided to facilitate disassembling/reassembling work of a turbine unit, thus improving the ease-of-maintenance, and to commonly use the disassembly/reassembly jig, reducing the space required for storage and the cost. A disassembly/reassembly jig (31) for hoisting, moving, and positioning single component parts of an exhaust turbocharger (1) includes a hoisting section for performing hoisting with a crane and a plurality of holding sections (46, 47, and 48) for holding, as a single part, at least two types of component parts among the component parts (3, 4, and 16). Hoisting holes (41 to 44) are disposed at a position where the disassembly/reassembly jig (31) keeps an upright orientation without being inclined when hoisted in an empty load state and at positions where the component part (3, 4, or 16) keeps an attached orientation with respect to the exhaust turbocharger (1) when the disassembly/reassembly jig (31) is hoisted in a state in which the component part (3, 4, or 16) is held.
