Valve Rocker Arm - Installation

INSTALLATION






NOTE: The 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.

NOTE: A new fully assembled rocker arm and shaft assembly can be installed on either the right or left side of the engine. The identification marks (notches) (1) face toward the front of the engine for the left head and toward the rear of the engine for the right head.

2. Install the rocker arm and shaft assembly making sure that the identification marks (1) face toward the front of engine for left head and toward the rear of the engine for right head.
3. Tighten the rocker arm/shaft assembly bolts in the sequence shown to 31 Nm (275 in. lbs.).
4. Install the cylinder head covers Cylinder Head Cover(s) - Installation.
