The piston-connecting rod unit with an adjustable connecting-rod has, inside the piston (1) skirt, the holder (2) of the socket (3) of the ball (4) installed on the shaft (5) having, on the opposite side of the ball, a thread fixing the coupling (8) of the connecting-rod (9) foot. The manufacturing technology of the piston-connecting rod unit is that between the piston (1) skirt and the holder (2) brazed to it, the technological bushing is placed up to the half of the height of the holder (2) which protruding part is belled. After the socket (3) has been formed by means of the ball having diameter equal to the diameter of the ball (4), the threaded shaft (5) with ball (4) joined with it, the insert (6) and the washer (7) are inserted and then the technological bushing is taken out. Afterwards, the threaded shaft (5) is screwed into the coupling (8) with the sleeve (9) and the protection from loosening is made by means of gluing or screwing on a lock-nut (13).
