2. Remove camshaft sprocket (EXH) (1).

CAUTION:

• Hold the camshaft hexagonal part (A), and then secure the

camshaft.

• Do not rotate crankshaft and camshaft separately, so as

not to contact valve with piston.

NOTE:

The timing chain with the front cover installed is not disengaged

from the crankshaft sprocket and it is not dropped into the front

cover. Therefore, the timing chain tension holding device is not

necessary.

3. Turn the camshaft sprocket (INT) to the most advanced position.

CAUTION:

Installation and removal of the camshaft sprocket (INT) must be done in the most advanced posi-

tion. Make sure to follow the procedure exactly.

• The sprocket (C) and vane (camshaft coupling) (B) are

designed to spin and move within the range of a certain

angle.

• With the engine stopped and the vane in the most

retarded angle, it will not spin because it is locked to the

sprocket side by the internal lock pin (A).

• If the camshaft sprocket bolts are turned in the situation

described above, the lock pin will become damaged and

cause malfunctions because of the increased horizontal

load (cutting force) on the lock pin.

• Put the camshaft sprocket (INT) in the most advanced position:

a. Remove camshaft bracket (No. 1) (1).

NOTE:

Timing chain is present only for illustration purposes. Timing

chain is to be removed during removal procedure.

• Loosen the bolts in several steps, and then remove them.

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 leaks 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.

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) using suitable tool.

• 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)].

4. Remove the camshaft sprocket (INT):
a. Keeping the camshaft hexagonal part (A) in place using suitable

tool, 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.

5. 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.

6. Remove camshaft (EXH).
7. Remove camshaft (INT).
8. Remove valve lifter (if necessary).

• Identify installation positions, and store lifters without mixing them up.

9. Remove the alternator and bracket. Refer to 

CHG-29, "Exploded View"
