TIMING CHAIN

Check for cracks and any excessive wear at link plates. Replace

chain if necessary.

• In the same way as for the LH bank, inspect the timing chain and

associated parts on the RH bank.

INSTALLATION

NOTE:

• The above figure shows the relationship between the mating mark on each timing chain and that of the cor-

responding sprocket, with the components installed.

• To install the timing chain and associated parts, start with those on the RH bank. The procedure for installing

parts on the LH bank is omitted because it is the same as that for installation on the RH bank.

1. Make sure the crankshaft key and RH bank camshaft dowel pin

and LH bank camshaft dowel pin are facing in the direction

shown.

2. Install the camshaft sprockets.

• Install the camshaft sprocket INT (VTC) (A) and camshaft

sprockets EXH (B) by selectively using the groove of the

dowel pin according to the bank. (Common part used for both

exhaust banks.) 

NOTE:

Use the groove marked (R) for RH bank and (L) for LH bank.

• Lock the hexagonal part of the camshaft in the same way as

for removal, and tighten the bolts.

3. Install the crankshaft sprockets for both banks.

• Install LH bank crankshaft sprocket (B) and RH bank crank-

shaft sprocket (C) so that their flange side (A) (the larger diam-

eter side without teeth) faces in the direction shown.

NOTE:

The same parts are used but facing directions are different.

4. Install the timing chains and associated parts.

• Align the alignment mark on each sprocket and the timing chain for installation.

CAUTION:

• Before installing chain tensioner, it is possible to change the position of alignment mark on

timing chain and each sprocket. After the alignment marks are aligned, keep them aligned by

holding them by hand.

• Install the slack guides and tension guides onto the correct side by checking the identification mark on

the surface.

• Install the chain tensioner with the plunger locked in with the stopper pin.

CAUTION:

• Before and after the installation of the chain tensioner, make sure that the alignment mark on

the timing chain is not out of alignment.

• After installing the chain tensioner, remove the stopper pin to release the chain tensioner.

Make sure the chain tensioner is released.

• To avoid chain-link skipping of the timing chain, do not move crankshaft or camshafts until the

front cover is installed.

5. In the same way as for the RH bank, install the timing chain and associated parts on the LH bank.
6. Install the oil pump.

7. Install the oil pump drive spacer as follows:

• Install so that the front mark on the front edge of the oil pump

drive spacer faces the front of the engine.

• Insert the oil pump drive spacer according to the directions of

the crankshaft key and the two flat surfaces of the oil pump

inner rotor. 

• If the positional relationship does not allow the insertion, rotate

the oil pump inner rotor to allow the oil pump drive spacer to

be inserted.

8. Install the front oil seal using suitable tool.

CAUTION:

Do not scratch or make burrs on the circumference of the

oil seal.

9. Install the chain tensioner cover.

• Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

. 

10. Install the front cover as follows:
a. Install a new O-ring on the cylinder block.

Be sure to wipe off any excessive liquid gasket leaking onto

surface mating with oil pan.

11. Install the Intake valve timing control solenoid valve cover (RH)

(A) and Intake valve timing control solenoid valve cover (LH) (B)

as follows:

• Cross mark that can not be seen after assembly (C)

a. Apply liquid gasket (D) as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

CAUTION:

The start and end of the application of the liquid gasket

should be crossed at a position (C) that cannot be seen

after attaching the intake valve timing control solenoid valve cover.

b. Install the bolts and tighten them to specification in the numeri-

cal order shown.

• A: Intake valve timing control solenoid valve cover (RH)

• B: Intake valve timing control solenoid valve cover (LH)

12. Install the crankshaft pulley.

• Install the key of the crankshaft.

• Insert the pulley by lightly tapping it.

CAUTION:

Do not tap pulley on the side surface where the belt is installed (outer circumference).

13. Tighten the crankshaft pulley bolt.

• Lock the crankshaft using suitable tool, then tighten the bolt. 

• Perform the following steps for angular tightening:

TIMING CHAIN

a. Apply engine oil onto the threaded parts of the bolt and seating area.
b. Select the one most visible notch of the four on the bolt flange.

Corresponding to the selected notch, put a alignment mark

(such as paint) on the crankshaft pulley. 

14. Rotate the crankshaft pulley in normal direction (clockwise when

viewed from engine front) to check for parts interference.

15. Installation of the remaining components is in the reverse order

of removal.

INSPECTION AFTER INSTALLATION

• Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are

lower than required quantity, fill to the specified level. Refer to 

MA-16, "For North America"

.

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to the fuel piping, check for fuel

leakage at the 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 timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oil/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to

specified level if necessary.

• Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
