ABSTRACT:
A rocker arm assembly for an internal combustion engine has a removable valve stem locating member at one end thereof to locate the rocker arm relative to the valve stem during assembly of internal combustion engine, and a lubricating fluid directional control member at another end thereof for directing lubricating fluid from the pivot member, such as a hydraulic lash adjuster, toward the cam/rocker arm interface to provide lubricating fluid thereto. Once assembled, the valve stem locating member may be removed to further reduce the overall mass of the rocker arm assembly.
