1. Ensure that the right secondary camshaft drive chain tensioner (1) is being installed.




2. Using the EN 45027 - tool , reset the right secondary camshaft drive chain tensioner plunger.




3. Install the plunger into the right secondary camshaft drive chain tensioner body.




4. Compress the plunger into the body and lock the right secondary camshaft drive chain tensioner by inserting the EN 46112 - pins into the access hole in the side of the right secondary camshaft drive chain tensioner body.
5. Slowly release pressure on the right secondary camshaft drive chain tensioner. The right secondary camshaft drive chain tensioner should remain compressed.




6. Install a NEW right secondary camshaft drive chain tensioner gasket to the right secondary camshaft drive chain tensioner.
7. Install the right secondary camshaft drive chain tensioner bolts through the right secondary camshaft drive chain tensioner and gasket.
8. Ensure the right secondary camshaft drive chain tensioner mounting surface on the right cylinder head does not have any burrs or defects that would degrade the sealing of the NEW right secondary camshaft drive chain tensioner gasket.




9. Place the right secondary camshaft drive chain tensioner into position and loosely install the bolts to the block.





Caution: Refer to Fastener Caution Fastener Caution.

10. Verify the proper placement of the right secondary camshaft drive chain tensioner gasket tab (1).

1. First Pass
Tighten the right secondary camshaft drive chain tensioner bolts to 5 Nm (44 lb in).
2. Final Pass
Tighten the right secondary camshaft drive chain tensioner bolts to 25 Nm (18 lb ft).




11. Release the right camshaft drive chain tensioner by pulling out the EN 46112 - pins and unlocking the tensioner plunger.

Caution: Ensure that all timing chain tensioners are completely released. A timing chain tensioner that is not properly released can lead to serious engine damage.

12. Verify all primary and secondary camshaft drive chain timing mark alignments. Refer to Timing Chain Alignment Diagram Locations - Stage Two.
