Abstract:
1. An internal combustion engine comprising: a crankcase assembly; a crankshaft rotatably supported for rotation about a crankshaft axis by the crankcase assembly; a hub coupled to the crankshaft for rotation about the crankshaft axis; a compensator coupled for rotation with the crankshaft about the crankshaft axis and axially moveable along the crankshaft axis; a sprocket supported for rotation about the crankshaft axis and rotatable with respect to the crankshaft; a biasing member applying a biasing force biasing the compensator into engagement with the sprocket; and a resilient member positioned between the hub and the compensator, wherein in response to relative rotation between the compensator and the sprocket the compensator moves axially against the biasing force of the biasing member, and wherein sufficient axial movement of the compensator engages the resilient member with the hub and with the compensator to thereby resiliently limit further axial movement of the compensator.
