ABSTRACT:
An engine timing drive for driving a camshaft and an accessory such as a balance shaft has a transmission member including a fixed phase output for driving the accessory and a variable phase output for driving the camshaft. A preferred embodiment incorporates a planetary cam phaser in a driven sprocket that also carries a fixed phase output gear as an accessory drive.
