Camshaft - LH

Special Tool(s)





Material


Removal

NOTICE: The camshaft procedure must be followed exactly or damage to the valves and pistons will result.





1. Position the crankshaft damper spoke at the 12 o'clock position and the timing mark indentation at the 1 o'clock position.

2. Remove the LH valve cover.

3. NOTICE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

Loosen and back off the LH camshaft phaser and sprocket bolt one full turn.





4. Disconnect the LH camshaft position (CMP) sensor electrical connector.





5. Remove the LH CMP sensor and the bolt.

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





The No.5 cylinder camshaft 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.5 cylinder.





7. Remove only the 3 camshaft roller followers shown in the illustration.

8. NOTICE: The camshaft roller followers must be installed in their original locations. Record camshaft roller follower locations. Failure to follow these instructions may result in engine damage.

NOTE: Do not allow the valve keepers to fall off 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.





Using the special tool, remove only the 3 designated camshaft roller followers from the previous step.

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





Rotate the crankshaft clockwise, as viewed from the front, positioning the crankshaft damper spoke at the 6 o'clock position and the timing mark indentation at the 7 o'clock position.

10. NOTICE: Engine is not freewheeling. Camshaft procedure must be followed exactly or damage to valves and pistons will result.

NOTE: The Timing Chain Wedge tool must be installed square to the timing chain and the engine block.

NOTE: Engine front cover removed for clarity.





Install the special tool in the LH timing chain as shown.

11. NOTICE: Do not remove the Timing Chain Wedge tool at any time during assembly. If the special tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to Timing Drive Components. Timing Components

NOTICE: The timing chain must be installed in its original position onto the camshaft phaser and sprocket using the scribed marks, or damage to valves and pistons will result.

NOTE: RH shown, LH similar.





Scribe a location mark on the timing chain and the camshaft phaser and sprocket assembly.

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





Remove the 2 bolts and the LH cylinder head camshaft front bearing cap.

13. 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.





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





14. 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.

15. NOTICE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTICE: Only use hand tools to remove the camshaft phaser and sprocket bolt or damage may occur to the camshaft or camshaft phaser and sprocket.

NOTICE: Do not remove the Timing Chain Wedge tool at any time during assembly. If the special tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to Timing Drive Components. Timing Components





Remove the bolt and withdraw the camshaft from the camshaft phaser and sprocket assembly, leaving the camshaft phaser and sprocket assembly in place.

Discard the bolt and washer.

16. Inspect the camshaft phaser and sprocket for damage. For additional information, refer to Camshaft Phaser and Sprocket. In-Vehicle Repair

Installation

1. Lubricate the camshaft and camshaft journals with clean engine oil.

2. NOTICE: Do not remove the Timing Chain Wedge tool at any time during assembly. If the special tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to Timing Drive Components. Timing Components

NOTICE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.

NOTE: Do not allow the camshaft roller followers to move out of position when installing the camshaft.





Install the camshaft into the camshaft phaser and sprocket assembly and onto the head. Install a new camshaft phaser and sprocket bolt finger-tight.

3. NOTICE: Do not remove the Timing Chain Wedge tool at any time during assembly. If the special tool is removed or out of placement, the engine front cover must be removed and the engine must be retimed. For additional information, refer to Timing Drive Components. Timing Components

NOTICE: The timing chain must be installed in its original position onto the camshaft phaser and sprocket using the scribed marks, or damage to valves and pistons will result.

NOTE: RH shown, LH similar.





Verify the camshaft phaser and sprocket and timing chain scribe marks are still in alignment.

4. NOTE: Do not allow the camshaft roller followers to move out of position when installing the camshaft.

Install the camshaft bearing caps in their original locations.

- Lubricate the camshaft bearing caps with clean engine oil.

- Position the front camshaft bearing cap.

- Position the remaining camshaft bearing caps.

- Install the bolts loosely.





5. Tighten the bolts in the sequence shown. Tighten to 10 Nm (89 lb-in).

6. NOTE: Engine front cover removed for clarity.





Remove the special tools.





7. Rotate the crankshaft a half turn counterclockwise and position the crankshaft damper spoke at the 12 o'clock position and the timing mark indentation at the 1 o'clock position.





8. Verify correct camshaft position by noting the position of the No.5 cylinder intake and exhaust camshaft lobes.

9. 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. For additional information, refer to Cylinder Head. Cylinder Head Assembly

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





Using the special tool, install the 3 originally removed camshaft roller followers.





10. Install the CMP sensor and the bolt.





11. Connect the CMP electrical connector.

12. NOTICE: Only use hand tools to install the camshaft phaser and sprocket assembly or damage may occur to the camshaft or camshaft phaser and sprocket.

NOTICE: Damage to the camshaft phaser and sprocket assembly will occur if mishandled or used as a lifting or leveraging device.





Tighten the camshaft phaser and sprocket bolt in 2 stages:

- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Tighten an additional 90°.

13. In stall the LH valve cover.
