Abstract
An assembly clip for holding together a stationary hydraulic lash adjuster (SHLA) and a roller finger follower (RFF) in a valve train of an internal combustion engine (ICE) is provided. The SHLA has a pivot, and the RFF has a pivot cap configured to fit around the pivot. The assembly clip includes a first attachment section and a second attachment section configured to engage with the pivot cap and pivot, respectively, to attach the assembly clip to the RFF and SHLA, respectively. When assembled, the pivot and the pivot end are substantially located between the first attachment section and the second attachment section, the pivot cap covering at least a portion of the pivot. The assembly clip is made of an oil soluble material such that it may dissolve and break away after the valve train is assembled into the ICE, and the assembly clip no longer serves a function.
