The invention relates to the field of sintered circular cooling machines, particularly to a maintenance method for fracture and shifting faults of a track of a circular cooling machine. The method is characterized by including determining the circle center of a circular track again, calibrating concentricity of a frame column surface of the circular cooling machine, installing inner and outer horizontal tracks, measuring roundness, adjusting elevations of the inner and outer horizontal tracks, adjusting the motor directions of friction wheels of the circular cooling machine to be tangent with the track, and taking vertical columns of side stop tracks as measuring points for measurement through a total station. Compared with the prior art, circle determination is performed again for the circular cooling machine through determining a coordinate center, the inner and outer horizontal tracks and three circles of the inner side stop tracks during adjustment, therefore the transmission tangents of the two friction wheels of the circular cooling machine are guaranteed, the concentricity of the inner and outer trolley wheels of the circular cooling machine is inspected before preassembling a trolley, finally measured data are used for instructing the adjustment, more effects with less efforts are achieved, the fracture and shifting faults of the circular cooling machine are avoided after overhaul, slip shut down is reduced remarkably, and the failure rate of the circular cooling machine decreases linearly.
