>>D<< TIMING CHAIN TENSIONER
INSTALLATION

1. Install the timing chain tensioner on the cylinder block and

tighten it to the specified torque.

Tightening torque: 10

± 2 N⋅m (89 ± 17 in-lb)

2. Remove the hard wire (piano wire or the like) of

φ1.5 or

hexagonal bar wrench (1.5 mm [0.05 inch]) from the timing
chain tensioner. This enables the plunger of the timing chain
tensioner to push the tensioner lever to keep the timing
chain tight.

INTAKE V.V.T. SPROCKET

CAUTION

Never overhaul the V.V.T. sprocket.
1. Seal with a tape all the intake camshaft ports for the

advanced angle and the retarded angle.

2. Make a hole on the port for the advanced angle.

CAUTION

Fix the camshaft on a vise not to damage it.
3. Fixing the hexagonal area of the intake camshaft on a vise,

install the intake V.V.T. sprocket.

CAUTION

When applying air pressure, keep in mind that oil could
splash.
4. By applying air pressure slowly to the holed port for the

advanced angle, remove the stopper pin.

5. Turn the intake V.V.T. sprocket housing in the right and left

directions. Check it smoothly moves in the range of A
(approximately 20

°)

NOTE: The stopper pin is locked in the most retarded angle
position.

6. .After the check, remove the intake V.V.T. sprocket from the

intake camshaft

7. Completely remove the tape sealing the intake camshaft

ports for the advanced angle and for the retarded angle.

EXHAUST V.V.T. SPROCKET

CAUTION

Never overhaul the V.V.T. sprocket.
1. Seal with a tape all the exhaust camshaft ports for the

advanced angle and the retarded angle.

2. Make a hole on the port for the retarded angle.

CAUTION

Fix the camshaft on a vise not to damage it.
3. Fixing the hexagonal area of the exhaust camshaft on a

vise, install the exhaust V.V.T. sprocket.

CAUTION

When applying air pressure, keep in mind that oil could
splash.
4. By applying air pressure slowly to the holed port for the

retarded angle, remove the stopper pin.

5. Turn the exhaust V.V.T. sprocket housing in the right and left

directions. Check it smoothly moves in the range of A
(approximately 10

°)

NOTE: The stopper pin is locked in the most advanced
angle position.

6. .After the check, remove the exhaust V.V.T. sprocket from

the exhaust camshaft

7. Completely remove the tape sealing the exhaust camshaft

ports for the advanced angle and for the retarded angle.

VALVE CLEARANCE ADJUSTMENT

Measure valve clearance in the following procedure.

CAUTION

Always rotate the crankshaft clockwise.
1. Rotate the crankshaft clockwise to align the timing mark of

the V.V.T. sprocket with the top surface of the cylinder head
as illustrated. (Set the Number 1 piston at top dead center
on the compression stroke.)

2. Valve clearance can be measured at the illustrated location

in this condition.

3. Use a free gauge to measure clearance between the

camshaft and valve tappet.

Standard value (when engine is cold):

Intake side: 0.20

± 0.03 mm (0.008 ± 0.001inch)

Exhaust side: 0.30

± 0.03 mm (0.012 ± 0.001 inch)

4. If measured values are out of the standard value, record

measured values.

5. Rotate the crankshaft by one turn clockwise to set the

Number 4 piston at top dead center on the compression
stroke.
NOTE: The timing mark of the V.V.T. exhaust sprocket must
be at the illustrated position.

6. Valve clearance can be measured at the illustrated location

in this condition.

7. If measured values are out of the standard value, record

measured values.

8. If the measured value is out of the standard value, replace

the valve tappet.
NOTE: There are 47 kinds of valve tappets at intervals of
0.015 mm (0.0006 inch) in the range between 3.000 mm
(0.1181 inch) and 3.690 mm (0.145 inch).

9. Select a valve tappet in the following procedure.

(1) Measure thickness of a removed valve tappet.
(2) Calculate thickness of a valve tappet so that valve

clearance meets the standard value.

A: Thickness of valve tappet to be selected
B: Thickness of removed valve tappet
C: Measured valve clearance
Formula
Intake side: A = B + (C

− 0.20 mm [0.08 inch])

Exhaust side: A = B + (C

− 0.30 mm [0.012 inch])

Refer to "Removal and installation of camshaft" for removal,
installation and inspection procedure of valve tappets.
