Abstract
A method for mounting a camshaft in a bearing line of a cylinder head cover of an internal combustion engine may involve mounting a sealing ring in a groove extending radially circumferentially on an outer diameter of the camshaft. The sealing ring may be at least partly formed of an elastically deformable polymer such as polytetrafluoroethylene (PTFE). The method may further involve sliding a calibrating tool having a rotationally symmetrical opening onto the camshaft or sliding the camshaft into the calibrating tool. A smallest inside diameter of the rotationally symmetrical opening may be greater than an outside diameter of the camshaft in a region of the groove but less than an outside diameter of the sealing ring. Consequently, the sealing ring is pressed into the groove and is frictionally and interlockingly held in the groove.
