Abstract: A device for breaking separation of at least one bearing cap of a corresponding thrust block in the bearing assembly of engine cases provided with bearing bores which are arranged in-line, in particular crankshaft cases for alternative piston engines is provided. The device includes an extension mandrel comprising two half-mandrels insertable into at least one of the bearing bores. The half-mandrels being distant from each other in order to produce breaking separation force between the thrust block and the bearing cap. The bearing cap is clamped in such a way that it is non-rotatable except in a limited manner in the direction of breaking separation between a corresponding half-mandrel and a fixing device.

Abstract: A method for breaking separation of at least one bearing cap of a corresponding thrust block in the bearing assembly of engine cases provided with bearing bores which are arranged in-line, in particular crankshaft cases for alternative piston engines is provided. The method includes introducing an extension mandrel comprising two half-mandrels into at least one bearing hole, said half-mandrels being distant from each other in order to produce breaking separation force between the thrust block and the bearing cap. The bearing cap is clamped in such a way that it is non-rotatable except in a limited manner in the direction of breaking separation between a corresponding half-mandrel and a fixing device.

Abstract: The invention relates to a work holder device designed for holding work for machining by a machine tool and to a machine tool equipped with such a holder device. The work holder device includes a carrier fixture and at least one transferable jig adapted to be attached to the carrier fixture, such transferable jig having a work trap for receiving and holding the work, the at least one transferable jig being able to be inserted on a linear guide arrangement like a drawer into a trap of the transferable jig in an insertion plane and being able to be fixed in the trap in a fixing position.

Abstract: The invention relates to a method for breaking separation of at least one bearing cap of a corresponding thrust block in the bearing assembly of engine cases provided with bearing bores which are arranged in-line, in particular crankshaft cases for alternative piston engines. The inventive method consists in introducing an extension mandrel comprising two half-mandrels into at least one bearing hole, said half-mandrels being distant from each other in order to produce breaking separation force between the thrust block and the bearing cap. Said invention is characterized in that the bearing cap is clamped in such a way that it is non-rotatable except in a limited manner in the direction of breaking separation between a corresponding half-mandrel and a fixing device.
