Abstract
Making or undoing an oil press fit between a first and second components at respective fitting surfaces includes pressurizing a channel in the second component to produce or release the oil press fit. Oil is applied by the channel during pressurization from a connection between a first fitting surface on the first component and a second fitting surface on the second component. The channel is defined, at least in sections, by two holes intersecting at a point of intersection, one of which is 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. Prior to pressurization, an elastically deformable sealing element is placed at the point of intersection, and it is then pressed into the second part of the hole at the point of intersection in a sealing manner.
