Bearing assembly of camshafts on a cylinder head of an internal combustion engine

An apparatus, comprising:

• a bearing assembly (10) of a first camshaft (12) and a second camshaft (14) on a cylinder head (16) of an internal combustion engine of a motor vehicle, wherein the first and second camshafts (12, 14) are mounted rotatably on the cylinder head (16);
• wherein the first camshaft (12) has a first recess (20) that is formed in an outer periphery of an outer surface (18) of the first camshaft (12) and opens outwards in a radial direction of the first camshaft (12), wherein a tool is insertable into the first recess (20) and can be brought into positive cooperation with the first camshaft (12) such that the first camshaft (12) can be secured against rotating by the tool, and wherein the first recess (20) is disposed offset from a center of the first camshaft (12) in the radial direction;
• wherein the second camshaft (14) has a second recess (20) that is formed in an outer periphery of an outer surface (18) of the second camshaft (14) and opens outwards in a radial direction of the second camshaft (14), wherein the tool is insertable into the second recess (20) and can be brought into positive cooperation with the second camshaft (14) such that the second camshaft (14) can be secured against rotating by the tool, and wherein the second recess (20) is disposed offset from a center of the second camshaft (14) in the radial direction;
• a cylinder head hood (22), wherein the cylinder head hood (22) is attached to the cylinder head (16), wherein the cylinder head hood (22) has a first through-opening (24) matched with the first recess (20) through which the tool is insertable, and wherein the cylinder head hood (22) has a second through-opening (24) matched with the second recess (20) through which the tool is insertable;
• wherein a first wall area (W1) of the cylinder head hood (22) that at least partially delimits the first through-opening (24) and a second wall area (W2) of the cylinder head hood (22) that at least partially delimits the second through-opening (24) are disposed at different heights in a vertical direction of the internal combustion engine of the motor vehicle.
