Removal

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

1. Remove the engine front cover. For additional information, refer to Engine Front Cover Service and Repair.

2. Using the crankshaft holding tool, rotate the crankshaft clockwise until the keyway is at the 12 o'clock position.





3. Verify the data matrix on the camshafts is facing up, if not, rotate the crankshaft clockwise one revolution.





4. Remove the 2 bolts and the RH primary timing chain tensioner.





5. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the RH timing chain tensioner arm. Return the crankshaft keyway to the 12 o'clock position after removing the RH timing chain tensioner arm.
Remove the RH timing chain tensioner arm.






6. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the RH timing chain guide. Return the crankshaft keyway to the 12 o'clock position after removing the RH timing chain guide.
Remove the bolt and the RH timing chain guide.






7. Remove the RH primary timing chain.





8. Remove the 3 RH intake Variable Camshaft Timing (VCT) assembly bolts and the 3 RH exhaust VCT (Variable Camshaft Timing) assembly bolts.





9. Slide the RH VCT (Variable Camshaft Timing) assemblies and secondary timing chain forward 2 mm (0.078 in).





10. Depress the RH secondary timing chain tensioner and turn the tensioner 90 degrees.





11. Remove the RH VCT (Variable Camshaft Timing) assemblies and the RH secondary timing chain.





12. Using the crankshaft holding tool, rotate the crankshaft counterclockwise until the crankshaft keyway is at the 9 o'clock position.





13. Remove the 2 bolts and the LH primary timing chain tensioner.





14. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the LH timing chain tensioner arm. Return the crankshaft keyway to the 9 o'clock position after removing the LH timing chain tensioner arm.
Remove the LH timing chain tensioner arm.






15. NOTE: It may be necessary to rotate the crankshaft slightly to provide enough slack in the chain to remove the LH timing chain guide. Return the crankshaft keyway to the 9 o'clock position after removing the LH timing chain guide.
Remove the bolt and the LH timing chain guide.






16. Remove the LH primary timing chain.





17. Remove the 3 LH intake Variable Camshaft Timing (VCT) assembly bolts and the 3 LH exhaust VCT (Variable Camshaft Timing) assembly bolts.





18. Slide the LH VCT (Variable Camshaft Timing) assemblies and secondary timing chain forward 2 mm (0.078 in).





19. Depress the LH secondary timing chain tensioner and turn the tensioner 90 degrees.





20. Remove the LH VCT (Variable Camshaft Timing) assemblies and the LH secondary timing chain.





21. Remove the crankshaft sprocket.
