  1. CAUTION: Do not turn the engine over with the camshaft positioning tool or damage to the camshaft sprocket or the bolt may occur.

    Install the Camshaft Positioning Tool.

    Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o'clock. Tighten the Camshaft Holding Tools to maintain camshaft pre-positioning.
