Zusammenfassung:The invention discloses a special test method for a large sliding bearing, which relates to the technical field of electromechanical equipment and comprises the following steps of: flatly placing the large sliding bearing in a natural state; a special tester is arranged, the special tester is adopted to obtain the height change value of the top of the oil slinger or the top of the journal through one of the first sight hole and the second sight hole before and after the high-pressure oil pump is started, and the height change value serves as the bearing bush oil clearance value after the high-pressure oil pump is started. The special tester is adopted to obtain height change values through the first sight hole and the second sight hole respectively, the oil clearance jacking amount at the inner journal of the large sliding bearing is directly measured, operation is easy, measurement is accurate, work of connecting shaft disassembly and bearing disassembly and disassembly is avoided, and therefore the advantag
