摘要： The invention relates to a method of installing and turnably journaling a connecting rod (2) to a piston (1). The piston (1) is provided with a bearing member (3) having a curved bearing surface to be turnably engaged with an end part (2a) of the connecting rod (2) provided with similar bearing surface. The bearing member (3) has a ring-like shape with a cut-out (3a) at the side of the connecting rod (2). The end part (2a) of the connecting rod (2) is arranged through the cut-out (3a) into the piston (1) in a position, in which the end part (2a) of the connecting rod (2) and the bearing member (3) are essentially perpendicular with regard to each other. Then the connecting rod (2) or the piston (1) is moved further so that the end part (2a) of the connecting rod (2) becomes in contact with the bearing member (3). Thereafter the end part (2a) of the connecting rod (2) and the bearing member (3) are arranged to their final position by means of relative turning movement between the connecting rod (2) and the piston (1) so that the mutual bearing surfaces are aligned and substantially correspond to each other.
