TIMING CHAIN

b. Secure crankshaft pulley (1) with a pulley holder (commercial

service tool) (A).

c.

Apply new engine oil to thread and seat surfaces of crankshaft

pulley bolt.

d. Tighten crankshaft pulley bolt.

e. Put a paint mark (B) on crankshaft pulley (2), matching with any

one of six easy to recognize angle marks (A) on crankshaft pul-

ley bolt (1) flange. 

f.

Turn another 60 degrees clockwise (angle tightening).

• Check the tightening angle with movement of one angle mark.

g. Check that crankshaft rotates clockwise smoothly.

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

INSPECTION AFTER REMOVAL

Timing Chain

Check for cracks (A) and any excessive wear (B) at link plates and

roller links of timing chain. Replace timing chain if necessary.

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.

• 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-11, "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 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 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 check 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.

Removal and Installation

INFOID:0000000012197297

CAUTION:

The rotating direction in the text indicates all directions seen from the engine front.

REMOVAL

1. Remove the following parts.

• Intake manifold: Refer to 

EM-29, "Exploded View"

.

• Rocker cover: Refer to 

EM-24, "Exploded View"

.

• Front cover and timing chain related parts: Refer to 

EM-76, "Exploded View"

.

NOTE:

Removal of oil pump drive related part is not necessary.

2. Remove camshaft position sensor (PHASE) and exhaust valve timing control position sensor from cam-

shaft bracket.

CAUTION:

• Handle camshaft position sensor (PHASE) and exhaust valve timing control position sensor

carefully and avoid impacts.

• Never disassemble camshaft position sensor (PHASE) and exhaust valve timing control position

sensor.

• Never place sensor where it is exposed to magnetism.

3. Put the matching mark (A) on the camshaft sprocket (INT) (2),

camshaft sprocket (EXH) (3) and the camshaft bracket (1) as

shown in the figure.

NOTE:

It prevents the knock pin of the camshaft (INT) from engaging

with the incorrect pin hole when installing the camshaft sprocket

(INT).

4. Remove camshaft sprockets (INT and EXH).

• Secure hexagonal part (A) of camshaft with a wrench. Loosen

camshaft sprocket mounting bolts and remove camshaft

sprocket.

CAUTION:

• Never rotate crankshaft or camshaft while timing chain

is removed. It causes interference between valve and

piston.

• Never loosen the mounting bolts with securing anything

other than the camshaft hexagonal part or with tension-

ing the timing chain.

5. Remove camshaft bracket with the following procedure:
a. Loosen mounting bolts in reverse order as shown in the figure.
