ABSTRACT:
In an arrangement and method for mounting a camshaft onto a cylinder head of an internal combustion engine by camshaft bearings disposed on the cylinder head of the engine camshaft bearing by support seats which are formed integrally with the cylinder head and bearing caps which are formed integrally with a cylinder head cover mounted onto the cylinder head, at least one of the bearings is an assembly bearing with a separate assembly bearing cap that has a bearing opening of a diameter greater than that of the camshaft so that the camshaft when placed onto the bearing seats is not fully moved into the bearing seat openings but is fully engaged with the bearing seats only when the cylinder head cover is mounted onto the cylinder head whereby the camshaft in the assembly bearing is moved out of contact with the assembly bearing cap.
