5.

Support the bottom surface of engine using a transmission jack, and then remove the engine mounting
bracket and insulator (RH). Refer to 

EM-89, "Exploded View"

.

6.

Remove rocker cover. Refer to 

EM-47, "Exploded View"

.

7.

Set No. 1 cylinder at TDC of its compression stroke with the following procedure:

a.

Rotate crankshaft pulley (2) clockwise and align TDC mark
(without paint mark) (A) to timing indicator (1) on front cover. 

b.

Make sure the matching marks on each camshaft sprocket are
positioned as shown.

• If not, rotate crankshaft pulley one more turn to align matching

marks to the positions.

8.

Remove crankshaft pulley with the following procedure:

a.

Secure crankshaft pulley (1) using a suitable tool (A).

b.

Loosen and pull out crankshaft pulley bolts.

CAUTION:

Never remove the mounting bolts as they are used as a sup-
porting point for the pulley puller.

c.

Attach a pulley puller [SST: KV11103000] (A) in the M 6 thread
hole on crankshaft pulley, and remove crankshaft pulley. 

9.

Remove front cover with the following procedure:

a.

Loosen bolts in the reverse of the order shown.

b.

Cut liquid gasket by prying the position (

) shown, and then

remove the front cover.

10. Remove camshaft position sensor (PHASE) from rear end of cylinder head.

CAUTION:

Handle it carefully and avoid impacts.

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

CAUTION:

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

camshaft.

• Never rotate crankshaft and camshaft separately, so as

not to contact valve with piston in the following steps.

12. 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 for the following reasons.

CAMSHAFT

• 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 mounting bolts are turned in the

situation described above, the lock pin will become dam-
aged and cause malfunctions because of the increased
horizontal load (cutting force) on the lock pin.

a.

Remove camshaft bracket (No. 1) (1).

• 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 (B) narrowed to the top of the air gun

(A) to prevent air leakage from the oil hole. Securely apply the
air pressure to the oil hole.

CAUTION:

• There are other oil holes in the side grooves. Never 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-
natively.
• Finally rotate the sprocket of the camshaft sprocket (INT) counterclockwise [the direction shown by the

arrow (

)].

• Perform the work while applying the air pressure to the oil hole.

• If the lock pin is not released by hands, 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.

• Make sure that it is in the most advanced angle position by

seeing if the stopper pin groove (A) and the stopper pin hole (B) are matched up as shown.

e.

Complete the applying procedure of air pressure and the holding procedure of 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 coming 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)].

13. Remove camshaft brackets (No. 2 to 5).

• Loosen bolts in several steps in the reverse of the order

shown.

NOTE:
The camshaft bracket (No. 1) has been already removed.

14. Remove camshaft (EXH).
