Abstract
An input component (3) of a clutch is fastened to the output end (5) of the crankshaft (7) of an internal combustion engine by a force-fit coupling (11) in which a radial force fit is produced by axial forces which are applied to the coupling (11) by a tool inserted through the hub (21) of a clutch disc (23) or applied to the hub, which in turn applies the axial force on the coupling. The coupling enables the clutch (1), including the flywheel (3) and the clutch disc (23), to be installed on the crankshaft (7) as an assembled unit. The force-fit coupling (11) comprises an expanding conical, element (61), arranged in a central opening (59) of the output end (5) of the crankshaft (7), which expands the output end (5) of the crankshaft radially.
