    • A housing is disclosed for a hydraulic radial piston motor, with a first housing part and with a second housing part, between which a cam ring is arranged, which thus forms a centre housing part. During operation of the radial piston motor, a stroke motion is generated in revolving cylinder-piston units via cams on the cam ring. In particular, this is a stroke motion of the pistons that are supported by a respective roller on the cam ring. At least one first seal, which also contacts the first housing part in an assembled state of the housing, is placed on the cam ring. When the first housing part is lowered onto the cam ring during assembly of the housing, the first seal is prevented from slipping and falling. A method for assembling a housing for radial piston motors is also disclosed, in which the first seal is initially mounted on the cam ring or laid thereon, and the first housing part is subsequently lowered onto the cam ring and therefore onto the first seal.
