A machine housing of a piston machine is disclosed. The machine housing is formed in two parts. The machine housing has a main housing which is closed off by a connection plate. Here, the connection plate is screwed to the main housing by means of a plurality of screws, and is positioned with low tolerances with respect to said main housing by means of two centering pins. Here, the centering pins are arranged with twofold rotational symmetry with respect to a shaft axis of a drive shaft of the piston machine. In contrast, screw positions do not have rotational symmetry with respect to said shaft axis. This prevents incorrect mounting of the connection plate.
A machine housing of a hydraulic machine, having a housing section for accommodating a drive gear of the hydraulic machine, wherein said housing section is closed off by means of a connection plate which is connected to the housing section by means of screws, wherein to center the connection plate, two dowel pins are provided between the housing section and the connection plate, wherein dowel pin positions have twofold rotational symmetry and screw positions do not have rotational symmetry with respect to a shaft axis of a drive shaft of the hydraulic machine.
