Abstract (en)

A method is disclosed for mounting a dual phaser on a concentric camshaft to enable torque to be applied from an engine crankshaft to the outer tube of a concentric camshaft. The method comprises securing a bearing ring to an end of the outer tube for rotation with the outer tube, rotatably supporting the concentric camshaft in an engine by retaining the bearing ring within a pillar block, and securing to the bearing ring a dual phaser that includes a hydraulic phaser having an input member driven in use by the engine crankshaft and an output member connected to the bearing ring. In the invention, flow passages are provided in the bearing ring to communicate with passages in the pillar block and to communicate through an axial end face of the bearing ring with passages leading to working chambers of the hydraulic phaser to enable the phase of the outer tube of the camshaft to be advanced and retarded relative to the phase of the engine crankshaft.
