Rocker Arm / Adjuster Assembly: Installation

WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Rocker arm and shaft assembly can be installed either prior to or after (preferred) cylinder head installation.

Rotate camshafts to the position shown in (Fig 1 ). With the camshafts in these positions the lobes are in a neutral position (no load to the valve). This will allow the rocker arm shaft assembly to be tightened into position with little or no valve spring load on it.
