REMOVAL
1. Remove front wheel (RH).
2. Remove front fender protector (RH).
3. Drain engine oil.
CAUTION:

Be sure to perform this step when engine is cold.
4. Remove the following parts.
• Intake manifold: 
• Drive belt: 
• Water pump pulley: 
• Ground cable (RH)
5. Support the bottom surface of engine using a transmission jack, and then remove the engine mounting bracket and insulator (RH). Refer to EM-83, “Exploded View”.
6. Remove rocker cover. 
7. Set No. 1 cylinder at TDC of its compression stroke with the following procedure:
a. Rotate crankshaft pulley (2) clockwise and align TDC mark
(without paint mark) (A) to timing indicator (1) on front cover.
b. Make sure the matching marks on each camshaft sprocket are
positioned as shown in the figure.
• If not, rotate crankshaft pulley one more turn to align matching
marks to the positions in the figure.
8. Remove crankshaft pulley with the following procedure:
a. Secure crankshaft pulley (1) using a pulley holder (commercial
service tool) (A).
b. Loosen and pull out crankshaft pulley bolts.
CAUTION:
Never remove the mounting bolts as they are used as a supporting point for the pulley puller.
c. Attach a pulley puller [SST: KV11103000] (A) in the M 6 thread
hole on crankshaft pulley, and remove crankshaft pulley.

9. Remove front cover with the following procedure:
a. Loosen bolts in the reverse of the order shown in the figure.
b. Cut liquid gasket by prying the position ( ) shown in the figure,
and then remove the front cover.
10. Remove front oil seal from front cover.
• Remove by lifting it up using a suitable tool.
CAUTION:
Be careful not to damage the front cover.
11. Remove chain tensioner (1) with the following procedure.
a. Fully push down the chain tensioner lever (A), and then push the
plunger (C) into the inside of tensioner.
• The tab (B) is released by fully pushing the lever down. As a
result, the plunger can be moved.
b. Pull up the lever to align its hole position with the body hole position.
• When the lever hole is aligned with the body hole position, the plunger is fixed.
• When the protrusion parts of the plunger ratchet and the tab
face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then fix the lever at the upper position.
• Figure shows the example that a hexagonal wrench for 2.5 mm (0.098 in) is used.
d. Remove chain tensioner.

12. Remove the timing chain tension guide (2) and the timing chain slack guide (1).
13. Remove the timing chain (2).
• Pull the looseness of timing chain toward the camshaft sprocket (EXH) (1), and then remove the timing chain and
start the removal from camshaft sprocket (EXH) side.
CAUTION:
Never rotate crankshaft or camshaft while timing chain is removed. It causes interference between valve and piston.

14. Remove the crankshaft sprocket and the oil pump drive related parts with the following procedure.
a. Remove chain tensioner (1).
• Pull out from the shaft (B) and spring fixing holes (A).
b. Hold the top of the oil pump shaft using the TORX socket (size: E8), and then loosen the oil pump sprocket nuts and remove them.
c. Remove the crankshaft sprocket (1), the oil pump drive chain(2), and the oil pump sprocket (3) at the same time.
INSTALLATION

The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.

Nissan Qashqai timing chain

1. Install the crankshaft sprocket and the oil pump drive related
parts with the following procedure:

a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
• Install the crankshaft sprocket so that its invalid gear area (A)
is towards the back of the engine.
• Install the oil pump sprocket so that its hexagonal surface
faces (B) the front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.
b. Hold the top of the oil pump shaft using the TORX socket (size:
E8), and then tighten the oil pump sprocket nuts.

TIMING CHAIN
c. Install chain tensioner (1).
• Insert the body into the shaft (B) while inserting the spring into
the fixing hole (A) of cylinder block front surface.
• Make sure that the tension is applied to the oil pump drive
chain after installing.
2. Install timing chain with the following procedure.
• Install by aligning matching marks on each sprocket and timing chain.
• If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
• Check matching mark position of each sprocket and timing chain again after installing the timing chain, keep Matching marks aligned by holding them with a hand.
• To avoid skipped teeth, never rotate crankshaft and camshaft until front cover is installed.
3. Install timing chain tension guide (2) and timing chain slack
guide (1).
4. Install chain tensioner (1).
• Fix the plunger at the most compressed position using a stopper pin (A), and then install it.
• Securely pull out the stopper pin after installing the chain tensioner.

5. Check matching mark position of timing chain and each sprocket again.
6. Install the front oil seal to the front cover. Refer to EM-71, “FRONT OIL SEAL : Removal and Installation”
7. Install front cover with the following procedure:
a. Apply a continuous bead of liquid gasket with tube presser
(commercial service tool) to front cover as shown in the figure.
Use Genuine Liquid Gasket or equivalent.

bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark (B) on crankshaft pulley, mating with any one of
six easy to recognize angle marks (A) on crankshaft bolt flange
(1).

d. Turn another 60 degrees clockwise (angle tightening).
• Check the tightening angle with movement of one angle mark.
10. Make sure that crankshaft turns smoothly by rotating by hand clockwise.
11. Install in the reverse order of removal, for the rest of parts.

TIMING CHAIN
Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-21, “Fluids and Lubricants”.
• Use procedure below to check for fuel leakage.
– Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
– Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after the engine start. However, this does not indicate an unusualness. Noise will stop after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
