Abstract

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).
