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 front oil seal from front cover.
 Remove by lifting it up using a suitable tool.
CAUTION:
Be careful not to damage the front cover.
11. Remove chain tensioner (1) with the following procedure.
a. Fully push down the chain tensioner lever (A), and then push the
plunger (C) into the inside of tensioner.
 The tab (B) is released by fully pushing the lever down. As a
result, the plunger can be moved.
b. Pull up the lever to align its hole position with the body hole posi-
tion.
 When the lever hole is aligned with the body hole position, the
plunger is fixed.
 When the protrusion parts of the plunger ratchet and the tab
face each other, both hole positions are not aligned. At that
time, correctly engage them and align these hole positions by
slightly moving the plunger.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then fix the lever at the upper
position.
 The example that a hexagonal wrench for 2.5 mm (0.098 in) is used as shown.
d. Remove chain tensioner.

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).

 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).
