b. Apply the following air pressure to the No. 1 journal oil hole (A)
of camshaft (INT) (1) shown using an air gun.
• Apply the air pressure into the oil hole on the second groove
from the front of camshaft thrust (B).
• Proceed all the way through step “e” with the air pressure on.
• Attach the rubber nozzle narrowed to the top of the air gun to
prevent air leakage from the oil hole (A). Securely apply the air
pressure to the oil hole.
WARNING:
Eye protection should be worn as needed.
CAUTION:
• There are other oil holes in the side grooves. Do not use the incorrect oil holes.
• Be sure not to damage the oil path with the tip of the air gun.
• Wipe all the oil off the air gun to prevent oil from being blown all over along with the air, and the
area around the air gun should be wiped with a rag when applying air pressure. Eye protection
should be worn as needed.
NOTE:
The air pressure is used to move the lock pin into the disengage position.
c. Hold the camshaft sprocket (INT) with hands, and then apply the power counterclockwise/clockwise alter-
nately.
• Finally rotate the sprocket of the camshaft sprocket (INT)
counterclockwise [the direction shown by the arrow (
)].
• Perform the work while continuously applying the air pressure
to the oil hole.
• If the lock pin is not released, tap the camshaft sprocket (INT)
lightly with a plastic hammer (A).
• If the camshaft sprocket (INT) is not rotated counterclockwise
even if the above procedures are performed, check the air
pressure and the oil hole position.
d. While doing the above, once you hear a click (the sound of the
internal lock pin disengaging) from inside the camshaft sprocket
(INT), start turning the camshaft sprocket (INT) in the counter-
clockwise direction in the most advanced angle position.
• Keep the air pressure on.
• If there is no click, as soon as the vane side (camshaft side)
starts moving independently of the sprocket, the lock pin has
become disengaged.

• Check that it is in the most advanced angle position by seeing if the stopper pin groove (A) and the stop-
per pin hole (B) are matched up as shown.
e. Stop applying air pressure and release the camshaft (INT).
f.
Insert the stopper pin (A) into the stopper pin holes in the cam-
shaft sprocket (INT) and lock in the most advanced angle posi-
tion.
CAUTION:
No load is exerted on the stopper pin (spring reaction, etc.).
Since it comes out easily, secure it with tape (B) to prevent
it from falling out.
NOTE:
The stopper pin shows one example of a hexagonal wrench for
2.5 mm (0.098 in) [length of inserted section: approximately15
mm (0.59 in)].
10. Remove the camshaft sprocket (INT):
a. Keeping the camshaft hexagonal part (A) in place with the
wrench, loosen the bolts for the camshaft sprocket (INT) (2).
CAUTION:
• Do not drop stopper pin.
• Tape (C) the stopper pin (B) so it does not come out.
• Do not subject it to impact by dropping.
• Do not disassemble. [Do not loosen the three bolts (A)].
NOTE:
While removing the camshaft sprocket (INT), if you have taken
out the stopper pin and the lock pin has been rejoined in the
most retarded angle, do the following to restore it.
i.
Install the camshaft (INT) and tighten the bolts enough to pre-
vent air from leaking out.
CAUTION:
The internal lock pin will get damaged, so keep the torque
on the bolts to the minimum required to prevent air from
escaping.
ii.
Apply the air pressure, disengage the lock pin, and turn the vane to the most advanced angle position.
iii. Insert the stopper pin.
iv. Remove camshaft sprocket (INT) from the camshaft.
11. Remove camshaft brackets (No. 2 to 5).

• Loosen bolts in several steps in the reverse order as shown.
NOTE:
The camshaft bracket (No. 1) has been already removed.
12. Remove camshaft (EXH).
13. Remove camshaft (INT).
14. Remove valve lifter.
• Identify installation positions, and store lifters without mixing them up.
15. Remove intake valve timing control solenoid valve (1).
16. Remove the alternator and bracket, remove the plug (2), and
then remove the oil filter. Refer to
.
17. Remove exhaust valve timing control solenoid valve.
18. Remove the plug on the exhaust valve timing control solenoid valve and the oil filter. Refer to
19. For component inspection after removal, refer to
INSTALLATION
CAUTION:
Do not reuse O-rings or washers.
1. Install oil filter (1) for intake and exhaust valve timing control
solenoid valves.
CAUTION:
Do not reuse washers.
NOTE:
The intake side is shown as an example.
• The oil filter (1) and washer (2) are assembled to the plug (3),
and then install them in to the cylinder head. Refer to
.
2. Install intake and exhaust valve timing control solenoid valves.
• Insert it straight into the cylinder head.
• Tighten bolts.
3. Install valve lifters.
• If they are reused, install them in the original positions.
4. Put a matching mark for positioning the camshaft (INT) and the camshaft sprocket (INT):
NOTE:
This helps prevent the knock pin from engaging with the incorrect pin hole after installing the camshaft
(INT) and the camshaft sprocket (INT).

a. Put the matching marks (A) on a line extending from the knock
pin position of camshaft (INT) (1) front surface.
• Put the marks on the visible position with the camshaft
sprocket installed as shown.
b. Put the matching marks on a line extending from the knock pin
hole (B) position of camshaft sprocket (INT) (2) as shown.
• Put the marks on the visible position with it installed to the
camshaft.
5. Put a matching mark for positioning the camshaft (EXH) and the camshaft sprocket (EXH):
NOTE:
This helps prevent the knock pin from engaging with the incorrect pin hole after installing the camshaft
(INT) and the camshaft sprocket (EXH).
a. Put the matching marks (A) on a line extending from the knock
pin position of camshaft (EXH) (1) front surface.
• Put the marks on the visible position with the camshaft
sprocket installed as shown.

6. Install camshaft.
• Note that the camshafts (INT and EXH) have different shapes
at the rear.
• Install camshafts to the cylinder head so that knock pins (A) on
front end are positioned as shown.
NOTE:
Though camshaft does not stop at the portion as shown for the
placement of cam nose, it is generally accepted camshaft is
placed for the same direction as shown.
