Removal

1. Remove the engine front cover.

2. Remove the crankshaft sensor ring from the crankshaft.






3. Position the crankshaft keyway at the 12 o'clock position.






NOTE: If the camshaft lobes are not exactly positioned as shown, the crankshaft will require one full additional rotation to 12 o'clock.

4. The No.1 cylinder camshaft exhaust lobe must be coming up on the exhaust stroke. Verify by noting the position of the 2 intake camshaft lobes and the exhaust lobe on the No.1 cylinder.






NOTICE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations. Failure to follow these instructions may result in engine damage.

5. Remove only the 3 camshaft roller followers shown in the illustration from the RH cylinder head.






NOTE: Do not allow the valve keepers to fall off of the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be removed.

NOTE: It may be necessary to push the valve down while compressing the spring.

6. Using the Valve Spring Compressor, remove the 3 designated camshaft roller followers in the previous step from the RH cylinder head.






NOTICE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations. Failure to follow these instructions may result in engine damage.

7. Remove only the 3 camshaft roller followers shown in the illustration from the LH cylinder head.






NOTE: Do not allow the valve keepers to fall off of the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder head must be moved.

NOTE: It may be necessary to push the valve down while compressing the spring.

8. Using the Valve Spring Compressor, remove the 3 designated camshaft roller followers in the previous step from the LH cylinder head.






NOTICE: The crankshaft cannot be moved past the 6 o'clock position once set or engine damage may occur.

9. Rotate the crankshaft clockwise and position the crankshaft keyway at the 6 o'clock position.






NOTICE: If one or both tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. If cracks, tears, separation from the tensioner body or permanent compression of the seal bead is observed, install a new tensioner or engine damage may occur.

10. Remove the 2 bolts, the LH timing chain tensioner and tensioner arm.






11. Remove the 2 bolts, the RH timing chain tensioner and tensioner arm.






12. Remove the RH and LH timing chains and the crankshaft sprocket.
- Remove the RH timing chain from the camshaft sprocket.
- Remove the RH timing chain from the crankshaft sprocket.
- Remove the LH timing chain from the camshaft sprocket.
- Remove the LH timing chain and crankshaft sprocket.






NOTE: RH shown, LH similar.

13. Remove the LH and RH timing chain guides.
- Remove the 4 bolts.
- Remove both timing chain guides.






NOTICE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device. Only use hand tools to remove the camshaft phaser and sprocket assembly or damage may occur to the camshaft or camshaft phaser and sprocket.

14. Using the Cam Phaser Locking Tool, remove the bolt and the RH camshaft phaser and sprocket assembly.
- Discard the camshaft phaser and sprocket bolt.






15. Using the Cam Phaser Locking Tool, remove the bolt and the LH camshaft phaser and sprocket assembly.
- Discard the camshaft phaser and sprocket bolt.






NOTICE: Remove the front thrust camshaft bearing cam straight upward from the bearing towers or the bearing cap may be damaged from side loading.

16. Remove the 2 bolts and the RH camshaft front bearing cap.






NOTICE: The camshaft bearing caps must be installed in their original locations. Record camshaft bearing cap locations. Failure to follow these instructions may result in engine damage.

17. Remove the remaining bolts in the sequence shown and remove the remaining RH camshaft bearing caps.






18. Clean and inspect the RH camshaft bearing caps.
- The camshaft front thrust bearing cap contains an oil metering groove. Make sure the groove is free of foreign material.






19. Remove the RH camshaft.

NOTICE: Remove the front thrust camshaft bearing cap straight upward from the bearing towers or the bearing cap may be damaged from side loading.

20. Remove the 2 bolts and the RH camshaft front bearing cap.






NOTICE: The camshaft bearing caps must be installed in their original locations. Record camshaft bearing cap locations. Failure to follow these instructions may result in engine damage.

21. Remove the remaining bolts in the sequence shown and remove the remaining LH camshaft bearing caps.






22. Clean and inspect the LH camshaft bearing caps.
- The camshaft front thrust bearing cap contains an oil metering groove. Make sure the groove is free of foreign material.






23. Remove the LH camshaft.

NOTICE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations. Failure to follow these instructions may result in engine damage.

24. Remove all of the remaining camshaft roller followers from the cylinder heads.
