J 44212 Camshaft Holding Tool

For equivalent regional tools, refer to Special Tools.

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.

Caution: Refer to Fastener Caution in the Preface section.




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




Note: Do not use the stamped indicator marks for perpendicular alignment when installing the timing chain.

8. Install the right intake and exhaust camshafts sprockets onto the camshafts. The camshaft sprocket slot marked "RI" which indicates right intake, engages the intake camshaft pin and the camshaft sprocket slot 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 slot 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 slots and camshaft pins to the cylinder head.



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



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




Note: 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 and tighten 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).

Caution: Refer to Torque Reaction Against Timing Drive Chain Caution in the Preface section.




21. Tighten ALL camshaft sprocket bolts to 120 N·m (90 lb ft). Use the hex cast into each camshaft to prevent engine rotation and provide leverage.



22. Install the cylinder head core hole plugs located in the cylinder heads. Ensure the O-ring seal is on each cylinder head core hole plug to 4.5 N·m (39 lb in).
