A method for mounting a valve train (1) of an internal combustion engine, having, parallel to a row of cam followers (2), a camshaft (13) which has a cam (15) per cam follower (2), which cam (15) acts on the roller (10) of said cam follower (2), which camshaft (13) is supported with respect to the cylinder head (3) via an axial bearing (14), wherein a) the cam followers (2) are provided presorted into two main groups (A, B); b) the two mounts (11) of each cam follower (2) of the first main group (A) run with offset in relation to the longitudinal extent of the cam follower (2) in the side surfaces (12) with respect to one another in such a way that an axial line of the pin (9) differs in the clockwise direction from perpendicular; c) the offset of the second main group (B) differs in the counterclockwise direction from perpendicular, and d) a partial quantity of the first and second main group (A, B) are selected and mounted for each row of cam followers (2) in order to minimize/compensate for an axial thrust of the camshaft (13).
A method for mounting a valve train of an internal combustion engine that is provided with at least one row of cam followers of which each is supported on a bottom side on one end by a pivot support relative to a cylinder head of the internal combustion engine and acts on at least one gas exchange valve on the other end and has, on the other side, at least in a middle section, a cut-out in which a roller that runs on a pin sits, wherein said pin is supported in mounts of side surfaces of the cut-out, wherein and parallel to the row of cam followers there is a camshaft that has, for each of the cam followers, a cam or a sliding cam package acting on a respective one of the rollers and the camshaft is supported by an axial bearing relative to the cylinder head of the internal combustion engine, the method comprising:
A valve train of an internal combustion engine comprising a row of cam followers of which each said cam follower is supported on one side on a bottom side on one end by a pivot support relative to a cylinder head of the internal combustion engine and acts on the other end on at least one gas exchange valve and on the other side has at least in a middle section a cut-out in which a roller that runs on a pin sits, wherein said pin is supported in mounts of side surfaces of the cut-out, a camshaft runs parallel to the row of cam followers and the camshaft has for each of the cam followers, a cam or a sliding cam package acting on the roller and the camshaft is supported by an axial bearing relative to the cylinder head of the internal combustion engine, the camshaft loads a row of cam followers that act on identically acting ones of the gas exchange valves for each of the cylinders of the internal combustion engine, wherein each of the cylinders has two of the identically acting ones of the gas exchange valves, and for at least one of minimizing or compensating for an axial thrust of the camshaft on the axial bearing,
