Timing mechanism — removal (Nissan Qashqai J10)

Note: The direction of rotation referred to in the following text is viewed from the front of the engine.

1. Remove the front right wheel.

2. Remove the right fender liner.

3. Drain the engine oil.

Caution: Perform this step only on a cold engine.

4. Remove the following parts:

• Intake manifold.
• Attachment drive belt.
• Water pump pulley.
• Right ground cable.

5. Support the underside of the engine with a transmission jack, then remove the engine mounting bracket and right strut mount.

6. Remove the rocker arm cover.

7. Set the piston of the first cylinder to the top dead center position of the compression stroke as follows:

• Turn the crankshaft pulley (2) clockwise until the TDC mark is aligned (without color mark) (A) with pointer (1) on the front cover. The white color mark (B) is not used for engine maintenance.

• Make sure that the timing marks on each camshaft sprocket are positioned as shown in the illustration.

Note: If the marks are not in the specified position, rotate the crankshaft pulley one more revolution to set the marks to the desired position.

8. Remove the crankshaft pulley as follows:

Secure the crankshaft pulley (1) using a suitable tool (A).



Loosen the crankshaft pulley bolts.

Caution: Do not remove the crankshaft pulley bolts as they are used as the setting points for the pulley puller.

Install the pulley puller (KV11103000) (A) opposite the threaded holes for bolts MB (B) on the pulley, then remove the crankshaft pulley.



9. Remove the front engine cover as follows:

Unscrew the bolts in the reverse order shown in the figure.



Cut the heat-resistant seal to the point indicated by the arrow in the figure, and then remove the front engine cover.





10. Using a suitable tool, remove the front crankshaft oil seal from the front cover.

Caution: Be careful not to damage the front cover.

11. Remove the chain tensioner (1):

Fully press the tensioner lever (A), then press the plunger (C) into the tensioner. The tongue (B) is released by fully pressing the lever, as a result of which the plunger can move again.



Pull the rynag and align the hole in it with the hole in the body. When the hole in the lever coincides with the hole in the body, the plunger is fixed. If the protruding parts of the plunger ratchet and tongue are opposite each other, the holes do not match. At this point, you need to hook them correctly and align the holes by slightly moving the plunger.



Insert the locking pin (D) into the housing hole through the lever hole, then lock the lever in the upper position. The figure shows the use of a 2.5 mm Allen key for locking as an example.

Remove the chain tensioner.

12. Remove the damper (2) and the drive chain tensioner shoe.



13. Remove the timing chain (2). Pull the sagging part of the drive chain towards the exhaust camshaft sprocket (1) and remove the chain, starting from the exhaust camshaft sprocket side.

Caution: Do not rotate the crankshaft or camshafts after removing the timing chain. This may cause damage to the valves and pistons due to contact with each other.

14. Remove the crankshaft sprocket and oil pump drive parts:

Remove the chain tensioner (1) by pulling it off the axis (B) of the spring retainer hole (A).





Hold the top of the oil pump shaft with a TORX socket (size: E8), loosen and unscrew the oil pump sprocket nuts.

Simultaneously remove the crankshaft sprocket (1), oil pump drive chain (2) and oil pump sprocket (3).
