A camshaft drive assembly and a case and a chain guide for a camshaft drive assembly

A camshaft drive assembly comprising a case (2) is presented. At least one chain guide support (9) for at least one chain guide (7) for a timing chain (5) is formed integrally with the case (2). Preferably, the camshaft drive assembly comprises at least one chain guide (7), presenting a chain guide surface (7c) and a support surface (7d), the support surface (7d) facing one of the at least one chain guide support (9), whereby, the chain guide surface (7c), as seen in a cross-section perpendicular to the longitudinal direction of the timing chain (5), is oriented in an angle ( alpha ) in relation to the support surface (7d). Preferably, a part (10) of a water pump is formed integrally with the case (2).
