An engine is disclosed having a flywheel arrangement comprising a starter motor () having a pinion gear () at an output shaft. The pinion gear () constantly engages a corresponding crank gear of a crank wheel () located between an engine block and a flywheel assembly () of the engine. The crank wheel () is operatively connected to a crankshaft () of the engine via a one-way clutch unit (). The flywheel assembly () comprises a first flywheel body () connected to the crankshaft () of the engine. A second flywheel body () is rotatable relative to the first flywheel body () and coupled thereto such that is able to move elastically through a limited angular distance relative to the first flywheel body (). An interlocking device includes at least one locking arrangement () and is adapted to produce an interlocking connection between the second flywheel body () and the first flywheel body () during cranking of the internal combustion engine.

Flywheel arrangement for an internal combustion engine

A starter arrangement for an internal combustion engine the arrangement including a starter motor having a pinion gear coupled to an output shaft, the pinion gear being arranged in constant engagement with a corresponding crank gear of a crank wheel located between an engine block and a flywheel of the engine. The crank wheel is operatively coupled to a crankshaft of the engine via a one-way clutch unit loosely fitted to an end of the crankshaft, the crankshaft including a circumferential slot carrying a clip ring. The one-way clutch unit including a tube shaped hub loosely fitted to an end of the crankshaft, the axial movement of the one-way hub is fixed via a clip-ring in co-operation with a first axially delimiting member and a second axially delimiting member at least partially enclosed by the hub.
