Abstract: An assembly method for joining a telescopic rod part of a length-adjustable connecting rod, the method includes the following steps: providing a first section of the telescopic rod part, the first section comprising a connecting-rod eye and having a connection thread, providing a second section of the telescopic rod part, the second section comprising the piston rod, to which a piston is fixedly connected, and having a connection thread, wherein the second section has already arranged thereon at least sealing and/or supporting and/or closing elements, which are to be secured to the second section and which are to be mounted onto the piston rod and the piston, respectively, from the side of the associated connection thread, providing a tool for establishing a sufficiently strong frictional engagement with the piston rod and the piston, respectively, by means of form-fit clamping, establishing a sufficiently strong frictional engagement with the second section of the telescopic rod part by means of the tool, sc

Abstract: Adjustable-length connecting rod (100, 200) for a reciprocating piston engine, in particular for a reciprocating piston internal combustion engine, having a hydraulic cylinder for adjusting an effective connecting rod length (L) of the connecting rod (100, 200), which hydraulic cylinder has at least one piston and a first hydraulic operating chamber (21) and a second hydraulic operating chamber (22), a hydraulically actuable control device (8) which can be switched over at least between two switching states with an actuating piston (23) for controlling the adjustment of the connecting rod (100, 200), and a mechanically actuable actuating device (9) for switching the control device (8), which actuating device (9) is operatively connected via at least one hydraulic actuating line (11, 12) to the actuating piston (23) of the control device (8) for actuating it hydraulically.
