b. Cut the liquid gasket and remove the covers using Tool.

CAUTION:

Do not damage mating surfaces.

12. Remove the front oil seal using suitable tool.

CAUTION:

Do not damage front cover.

13. Remove chain tensioner cover using Tool (if necessary).

INSTALLATION

1. Install the front oil seal using suitable tool.

CAUTION:

Do not scratch or nick the oil seal.

2. Install the chain tensioner cover (if removed).

• Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-21, "Recommended Chemical Products and Sealants"

CAUTION:

• The components must be installed within 5 minutes of

the liquid gasket application. 

• Then allow 30 minutes for the liquid gasket to set before

operating the engine.

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

.

CAUTION:

• The components must be installed within 5 minutes of the

liquid gasket application. 

• Then allow 30 minutes for the liquid gasket to set before

operating the engine.

c. Check again that the timing alignment marks on the timing chain

and on each sprocket are aligned. Then install the front cover.

d. Install the bolts in the numerical order as shown.

e. After tightening, re-tighten to the specified torque.

CAUTION:

Be sure to wipe off any excessive liquid gasket oozing from

the cover. 

4. 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 (C) that cannot be seen after assembly

a. Apply liquid gasket (D) as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-21, "Recommended Chemical Products and Sealants"

.

CAUTION:

• The start and end of the liquid gasket application should

be crossed at a position (C) that cannot be seen after attaching the cover.

• The components must be installed within 5 minutes of the liquid gasket application. 

• Then allow 30 minutes for the liquid gasket to set before operating the engine.

b. Install the bolts in the numerical order as shown.

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

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

5. 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).

6. Tighten the crankshaft pulley bolt.

TIMING CHAIN COVER

• Lock the crankshaft using tool (A), then tighten the bolt. 

• Perform the following steps for angular tightening:

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.

Put an alignment mark (such as paint) on the crankshaft pulley

to correspond to the selected notch.

7. Rotate the crankshaft pulley in normal direction (clockwise when viewed from engine front) to check for

parts interference.

8. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• 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-15, "FOR NORTH AMERICA : Fluids and Lubricants"

 (United

States and Canada) or 

MA-16, "FOR MEXICO : Fluids and Lubricants"

 (Mexico).

• 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 leak-

age 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 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 oils/fluids including

engine oil and engine coolant.

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

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

ified level, if necessary.
