Tools Required

J 44212 Camshaft Holding Tool

1. Install the right secondary camshaft drive chain guide.



2. Loosely install the lower right secondary camshaft drive chain guide bolt.



3. Install the right secondary camshaft drive chain shoe.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

4. Install the right secondary camshaft drive chain shoe bolt.

Tighten
Tighten the right secondary camshaft drive chain shoe bolt to 25 N·m (18 lb ft).




5. Install the right secondary camshaft drive chain by sliding the chain down through the right cylinder head and placing the chain on the end of the camshafts.
6. Route the right secondary camshaft drive chain around the outer row of the intermediate drive chain sprocket teeth.



7. Install the right intake and exhaust camshaft sprockets into the right secondary camshaft drive chain.



8. Install the right intake and exhaust camshafts onto the camshafts. The camshaft sprocket notch marked "RI" which indicates right intake, engages the intake camshaft pin and the camshaft sprocket notch marked "RE" which indicates right exhaust, engages the exhaust camshaft pin.



9. If necessary, use an open wrench on the hex cast near the front of each camshaft to help align the sprocket notch to the camshaft pin.
10. Loosely install the right intake and exhaust camshaft sprocket bolts.



11. Ensure the perpendicular alignment of the right intake and exhaust camshaft sprocket notches and camshaft pins to the cylinder head.



12. Install the J 44212 to the right cylinder head camshafts.



13. Install the upper right secondary camshaft drive chain guide bolt.

Tighten
Tighten BOTH the upper and lower right secondary camshaft drive chain guide bolts to 25 N·m (18 lb ft).




14. Collapse the right secondary camshaft drive chain tensioner using the following procedure:

14.1.

Rotate the ratchet release lever counter-clockwise and hold.

14.2.

Collapse the right secondary camshaft drive chain tensioner shoe and hold.

14.3.

Release the ratchet lever and slowly release the pressure on the shoe.

15. When the ratchet lever moves to the first detent a click should be heard and felt. Insert a pin through the hole in the release lever in order to lock the right secondary camshaft drive chain tensioner shoe in the collapsed position.




Important: Ensure the right secondary camshaft drive chain tensioner release lever is facing out.

16. Install the right secondary camshaft drive chain tensioner.
17. Install the right secondary camshaft drive chain tensioner bolts.

Tighten
Tighten the right secondary camshaft drive chain tensioner bolts to 25 N·m (18 lb ft).

18. Remove pin from right secondary camshaft drive chain tensioner lever.



19. Ensure the correct alignment of all secondary timing components.



20. Ensure the correct alignment of all primary timing components (1, 2).



21. Tighten ALL camshaft sprocket bolts. Use the hex cast into each camshaft to prevent engine rotation and provide leverage.

Tighten
Tighten ALL camshaft sprocket bolts to 120 N·m (90 lb ft).




22. Install the chain guide access plugs located in the cylinder heads. Ensure the O-ring seal is on each access plug.

Tighten
Tighten the chain guide access plugs to 4.5 N·m (39 lb in).




23. Install a NEW O-ring on the camshaft position sensor.
24. Lubricate the O-ring with clean engine oil.
25. Install the camshaft position sensor.
26. Install the camshaft position sensor bolt.

Tighten
Tighten the camshaft position sensor bolt to 10 N·m (89 lb in).
