Method for producing or releasing a press-fit connection and tool

A method for producing or releasing an oil press fit between a first component and a second component at fitting surfaces of the first and the second components, the method comprising:

• providing a first component having a first fitting surface;
• providing a second component defining a channel and having a second fitting surface, wherein the channel is defined, at least in part, by two holes that intersect at a point of intersection, one of the two holes being subdivided by the point of intersection into a first part leading to the second fitting surface and a second part opening to an outer side of the second component;
• placing an elastically deformable sealing element at the point of intersection;
• pressing the elastically deformable sealing element into the second part of the one of the two holes at the point of intersection in a sealing manner;
• and
• pressurizing the channel in the second component, via which oil is directed under pressure starting from a pressure oil connection between the first fitting surface and the second fitting surface.
