TIMING DRIVE COMPONENTS

Installation


1. Install the LH and RH camshafts.
^ Lubricate the camshaft and camshaft journals with clean engine oil prior to installation.

2. NOTE: LH shown, RH similar.

Install the LH and RH camshaft bearing caps in their original locations.
^ Lubricate the camshaft bearing caps with clean engine oil.
^ Position the 2 front camshaft bearing caps.
^ Position the 8 remaining camshaft bearing caps.
^ Install the 20 bolts loosely.
^ Tighten to 10 Nm (89 inch lbs.) in the sequence shown.






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

NOTE: LH shown, RH similar.

Position the camshaft phaser and sprockets and 2 new camshaft phaser and sprocket bolts finger tight.






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

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

NOTE: LH shown, RH similar.

Using the Cam Phaser Locking Tool, tighten the LH and RH camshaft phaser and sprocket bolts in 2 stages.
^ Stage 1: Tighten to 40 Nm (30 ft. lbs.).
^ Stage 2: Tighten an additional 90 degrees.






5. Position the crankshaft with the Crankshaft Holding Tool, then remove the tool.






6. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.

CAUTION: Prior to installation, inspect the tensioner-sealing bead 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.

Compress the tensioner plunger, using a vise.






7. Install a retaining clip on the tensioner to hold the plunger in during installation.






8. Remove the tensioner from the vise.

9. If the copper links are not visible, mark 2 links on one end and 1 link on the other end, and use as timing marks.






10. Install the crankshaft sprocket, making sure the flange faces forward.






11. Install the 4 bolts and the LH and RH timing chain guides.
^ Tighten to 10 Nm (89 inch lbs.).






12. Position the lower end of the LH (inner) timing chain on the crankshaft sprocket, aligning the timing mark on the outer flange of the crankshaft sprocket with the single copper (marked) link on the chain.






13. NOTE: Make sure the upper half of the timing chain is below the tensioner arm dowel.

Position the timing chain on the camshaft sprocket with the camshaft sprocket timing mark positioned between the 2 copper (marked) chain links.






14. NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.

Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner and bolts.
^ Tighten to 25 Nm (18 ft. lbs.).






15. Remove the retaining clip from the LH timing chain tensioner.







16. Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) chain link.






17. NOTE: The camshaft phaser and sprocket will be stamped with one of the illustrated timing marks for the RH camshaft.

NOTE: The lower half of the timing chain must be positioned above the tensioner arm dowel.

Position the RH timing chain on the camshaft phaser and sprocket. Make sure the timing mark is positioned between the 2 copper (marked) chain links.






18. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner and the 2 bolts.
^ Tighten to 25 Nm (18 ft. lbs.).






19. Remove the retaining clip from the RH timing chain tensioner.






20. As a post-check, verify correct alignment of all timing marks.






21. Install the crankshaft sensor ring on the crankshaft.






22. CAUTION: If the components are to be reinstalled, they must be installed into their original locations. Failure to follow this instruction may result in engine damage.

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.

Using the Valve Spring Compressor, install all of the camshaft roller followers.
^ Lubricate the camshaft roller followers with clean engine oil prior to installation.






23. Install the engine front cover.
