Camshafts — Installation (Nissan Qashqai J10)

1. Install oil filters (1) (from the inlet side and the outlet side), assembling it with the plug (3) and inserting it into the cylinder head.



2. Install the intake valve opening control solenoid valve directly into the cylinder head and tighten the mounting bolts.

3. Install the valve lifters in the same position they occupied before removal.

4. Align the timing marks of the intake camshaft and sprocket as follows:

Note: This procedure is necessary to prevent the dowel pin from being aligned with the wrong hole after the intake camshaft and its sprocket are installed.

Place the corresponding marks (A) in one line passing through the locating pin of the front surface of the intake camshaft (1) and the sprocket (2), as shown in the figure.



Place the timing mark opposite the hole (B) of the intake camshaft sprocket (2) as shown in the figure.



5. Place the intake camshaft sprocket between the cylinder head and the front cover.

Note: The hole of the mounting pin (A) should face upward.

Attention. Make sure in advance in the TZM that the installation pin fits into the end of the camshaft.

6. Install the camshafts.

Note.

• The intake and exhaust camshafts differ from each other by the different shape of the rear part.
• The camshafts are installed in the cylinder head so that the dowel pins (A) on the front of the camshafts are in the position shown in the figure.

Note: The arrow points to the top side.

Note: For correct operation of the valve timing mechanism, it is necessary to place the camshafts strictly in the position shown in the figure.

7. Install the intake camshaft sprocket onto the intake camshaft as follows:

Align the timing mark (A) according to step 4. Carefully align the timing pin with the hole, then install the sprocket.



Raise the front of the intake camshaft (1) and tighten the bolt.



8. Place a piece of thin cloth (B) under the bottom of the camshaft, then fit a socket wrench onto the front of the raised intake camshaft (1).



9. Tighten the mounting bolt.

Caution: Hold the camshaft from turning by the hexagonal part (A).

10. Return the intake camshaft to the cylinder head.

11. Install the timing chain (1), aligning the timing mark (applied when removing the drive chain) (B) with installation mark (side knurling) (A) on the intake camshaft sprocket (2).



12. Install the camshaft covers (Nos. 2-5), locating the identification marks on the top surface as shown in the figure.

Note: The illustration shows the front of the engine. Install the camshaft caps so that the identification marks read correctly from the intake side of the engine.

13. Tighten the camshaft cover mounting bolts in several steps in the sequence shown in the figure.

Note: The arrow in the figure shows the front of the engine.

Tighten bolts No.9-11 to 2 Nm.

Tighten bolts No.1-8 in the specified sequence to a torque of 2 Nm.

Tighten all bolts in the specified sequence to a torque of 5.9 Nm.

Tighten all bolts in the specified sequence to a torque of 10.4 Nm.

14. Install the sprocket (2) on the exhaust camshaft, aligning the marks (A) made when removing the drive chain with the installation mark (stamp) (B) of the exhaust camshaft sprocket.

Note: If the position of the alignment pin does not match the hole, it is easy to move the exhaust camshaft for adjustment.

15. Tighten the exhaust camshaft sprocket mounting bolt (1).

Attention.

• To secure the camshaft, hold it with a wrench by the hexagonal part (A).
• Make sure that the marks made when removing the drive chain and all timing marks on the camshaft sprockets are in the correct position.

16. Remove the locking pin (A) and tension the drive chain by turning the crankshaft pulley slightly clockwise.



17. Install the threaded plug (2) into the front cover (1) of the engine. Apply sealant to the plug threads and tighten it.

Note: Use original sealant or equivalent.

18. Return the intake camshaft sprocket to its extreme position as follows:

Remove the locking pin (A) from the intake camshaft support.



Slightly turn the crankshaft pulley (1) clockwise (A) and move the intake camshaft sprocket to its extreme position. At the start of crankshaft rotation, the intake camshaft sprocket will turn, but with further rotation, the camshaft blades will also begin to move, thus reaching the extreme position.



If you start to rotate the crankshaft, the intake camshaft sprocket will also start to rotate. As it rotates, it will also cause the vanes to rotate (camshaft), as a result of which they will be set to the position of the maximum lag angle.





The maximum lag angle can be checked visually - the groove for the locking pin (A) should be turned clockwise.

By turning the crankshaft slightly counterclockwise, you can ensure that the locking pin has engaged by observing how the blades (camshaft) and the zopzdochka move simultaneously.

19. Install the camshaft position sensor (phase sensor) about the rear of the cylinder head and tighten the mounting bolts.

20. Check and adjust valve clearances.

21. Install the remaining parts in the reverse order of removal.
