Abstract
An engine assembly may include a cam phaser assembly coupled to a concentric camshaft. The cam phaser assembly may include first and second plate assemblies that have first and second vanes, an oil chamber housing located axially between the first and second plate assemblies, an oil distribution member, and a first fastener. The first and second plates may define first and second fastener passages. The oil chamber housing may define first and second chambers and a first central bore. The first vane may extend into the first chamber and the second vane may extend into the second chamber. The oil distribution member may be located within the central bore of the oil chamber housing and may define a third fastener passage. The first fastener may extend through the first, second, and third fastener passages and couple the cam phaser assembly to an outer shaft of the concentric camshaft.
