Timing Component Alignment Marks: Locations

CAUTION: Rotating the crankshaft in a counterclockwise direction may cause engine damage. Crankshaft journals are directionally machined. Rotating the crankshaft counterclockwise can raise burrs on bearing surfaces, reducing engine life.

Verify that the crankshaft keyway is in the nine o'clock position.




CAUTION: The crankshaft keyway must remain in the nine o'clock position until the cams are located, or damage to the valves may occur.

Rotate the LH and RH intake and exhaust camshafts to locate them in their neutral positions.




Rotate the crankshaft clockwise to position the keyway to the 11 o'clock position and remove the crankshaft damper bolt and washer.




Install the LH timing chain, aligning the timing index link (gold color) with the marks on the camshaft and crankshaft sprockets.




Rotate the crankshaft clockwise and position the keyway between the two o'clock and three o'clock positions for RH timing chain installation.




Verify that the timing index links (gold color) on the LH timing chain are in alignment with the timing index marks on the camshaft and crankshaft sprockets.




Install the RH timing chain, aligning the timing index links (gold color) with the marks on the camshaft and crankshaft sprockets.




Verify that the timing index links (gold color) on the RH timing chain are in alignment with the timing index marks on the camshaft and crankshaft sprockets.
