Abstract: The invention proposes a lever-type cam follower (1) which, for mounting a pin (7) for a cam roller, comprises bores (5, 6) in the region of its side walls (2, 3). The diameter of the bore (5) is larger than the diameter of the bore (6). Corresponding ends (8, 9) of the pin (7) are configured so that when mounted, the pin (7) is fixed in the bores (5, 6) by a press fit. Thus, the pin (7) can be inserted with its second end (8) at first through the larger bore (5) without causing damage to its raceway (8a) during assembly. At the same time, the press fit guarantees an excellent fixture of the pin (7) in the cam follower (1) with an all-round contact.

Abstract: Upper and lower contact discs (5, 6) are used for adjusting valve clearance with a mechanical cup tappet (1). The lower contact discs (6) have a substantially larger clearance adjusting range H.sub.SW than the upper contact discs (5). In this way, the invention succeeds in further reducing the total mass of the cup tappet (1) because, in an initial mounting of the cup tappet (1), the valve clearance is adjusted through the relatively small lower contact disc (6) and thus with relatively small mass fluctuations.
