At least a portion of the crank arm (25) is adapted to revolve about the main axis (XX), the connecting rod (14, 14a) being operatively connected to the crank arm (25) and its position adjustable along the length thereof in either direction along the longitudinal axis (Y). There is also provided various bearing mounting assemblies for use with the adjustable stroke reciprocating mechanism and carrier and shaft assemblies allowing controlled movement along the axis of the crank arm (25).
