Provided is a thrust bearing stress adjusting special tool of a water-turbine generator set. The tool is characterized by comprising measuring rods, dial indicators, a dial gauge stand, and a magnetic absorption base. The measuring rods are respectively installed out of elastic fuel tank protection covers, and measuring surfaces face downward. Each measuring rod is provided with two dial indicators. The measuring heads of the dial indicators face upward and contact with the measuring surfaces of the measuring rods, and are vertical to the measuring surfaces of the measuring rods. The dial indicators are fixedly connected with equipment foundation through the dial gauge stand and the magnetic absorption base. Through acquiring indicating gauge readings on the dial gauge stand, the tool calculates height values of elastic fuel tanks, and axial displacements of strut screws of the elastic fuel tanks are converted to the arc length of an adjustment round disk, so as to achieve an objective of adjusting heights of the elastic fuel tanks, realizing reliable and stable structure, simple manufacturing, and high precision. The tool is convenient to install and read, and is suitable to be used for overhaul field, and meanwhile problems that labor intensity of operating personnel is large, time consumption is long, and security risk is highlighted.
