ABSTRACT:
A cam follower is provided having a thin-walled ring fixed in the bore of the shaft to extend across a parting plane between the shaft and the support. The ring includes a radially inwardly directed collar having a bore or an internal thread which is mated to a corresponding thread of a threaded fastener. Due to the fact that the collar or the internal thread is arranged in the region of an edge of the securing ring remote from the cylinder head, the threaded fastener has an adequate axial mobility in the pre-assembled state. This freedom of movement enables excellent handling during final assembly.
