WIPO Patent Application WO/2019/139611

Kind Code:

A1

Abstract:

An idler shaft (100) used in an engine (10) having a gear cover (16) and a cylinder block (18). The idler shaft (100) includes an integral body (114) having a cylindrical shape. The idler shaft (100) is compressed between the gear cover (16) and the cylinder block (18) when assembled together such that the integral body (114) of the idler shaft (100) provides a clamp load and axial sealing between the gear cover (16) and the cylinder block (18). The idler shaft (100) further includes a passage way (116) fluidly connected to at least one of: the cylinder block (18) and the gear cover (16) for accommodating transmission of a fluid for the engine (10).
