An engine housing of an internal combustion engine has at least one bore and a bearing assembly mounted in the bore for rotatably supporting a camshaft via first and second rolling-element bearings that each have an outer ring. A slot-shaped gap extends from the bore through at least a part of the engine housing up to a point at the surface of the engine housing, at least one screw bore is disposed in a first portion of the engine housing on a first side of the slot-shaped gap, a threaded bore is disposed in a second portion of the engine housing on a second side of the slot-shaped gap, and a screw extends through the screw bore, across the slot-shaped gap and into the threaded bore and is configured to pull together the first portion and the second portion to clamp the outer ring.
