Abstract: A variable camshaft timing system, includes a camshaft phasing mechanism that selectively changes an angular position of an input relative to an output; a first camshaft phaser sprocket, coupled with the input of the camshaft phasing mechanism, configured to engage a first endless loop that communicates rotational force from a crankshaft to the input of the camshaft phasing mechanism; and a second camshaft phaser sprocket, axially spaced from the first camshaft phaser sprocket and coupled with the output of the camshaft phasing mechanism, configured to engage a second endless loop that communicates rotational force from the output of the camshaft phasing mechanism to a camshaft and change the angular position of the camshaft relative to the crankshaft, wherein the camshaft phasing mechanism is mounted about an axis that is different from an axis of camshaft rotation.
