Abstract
A hydraulic system includes a hydraulic device and a determination device. The hydraulic device includes a casing, a cylinder block including first detected portions and one or more second detected portions on the outer peripheral surface of a cylinder block body, a piston, a linkage mechanism, and a sensor that is provided at a position corresponding to each of the detected portions. When the detected portion passes by during rotation of the cylinder block, the sensor outputs one of first and second signals. The determination device determines, based on an output from the sensor, whether the cylinder block is a suitable product. The first detected portions are circumferentially spaced apart at a predetermined first distance on the outer peripheral surface. The second detected portion(s) are circumferentially spaced apart from the adjacent first detected portion at a second distance different from the first distance on the outer peripheral surface.
