Title: Crankcase for a combustion engine

Abstract: A crankcase (1) is described for a combustion engine with cylinders arranged in V formation that is divided into two parts (2, 3) along a plane of separation (4) going through the axis of the crankshaft (6), such halves connected with each other by means of bearing screws (9) at right angles to the plane of separation (4) on either side of the crankshaft bearing (7), and by means of cylindrical adapters (12), which lock into fitting drill holes (13) provided between the two case halves (2, 3). In order to achieve beneficial construction conditions, it is proposed that the adapters (12) running parallel to the axis of the crankshaft (6) lie in the plane of separation (4) and are each penetrated by one bearing screw (9). In a second embodiment, the adapters (12) are positioned between two of the bearing screws (9) on each side of the crankshaft bearing (7).
