Tappet Guides and Tappets

Tappets and their guides

Tappets transmit the movements of the cams. They convert the circular movement of the cams into a linear movement that is passed on to the valves.

In the air-cooled V-Twin engines from Harley-Davidson, roller tappets have performed this task since the side valve engines of 1929, with a few exceptions. The tappets are perpendicular to the axis of the camshaft and the movement is transmitted directly. The tappets are guided in separate components with precise bores, the tappet guides. These guides can be replaced separately in the event of wear. On models without hydraulic valve lash adjustment, the tappets have adjusting screws for the valve lash. On the tappets of the large Twins from 1952 onwards and the Sportster from 1986 onwards, the tappets house the hydraulic compensation units for the valve clearance.
