To install:


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

  1. Rotate camshaft gears clockwise to where the number one cylinder intake valves would just start to open. The camshaft lobes are now 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.

  3. Install the rocker arm and shaft assembly making sure that the identification marks face toward the front of engine for left head and toward the rear of the engine for right head.
