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).

1. Install the oil filter (1).
 The oil filter is assembled to the plug (3), and then install it to
the cylinder head.
2. Install intake valve timing control solenoid valve.
 Insert it straightly into the cylinder head.
 Tighten bolts after placing it completely.
3. Install valve lifter.
 If it is reused, install in its original positions.
4. Put a matching mark for positioning the camshaft (INT) and the camshaft sprocket (INT) with the following
procedure.
NOTE:
It prevents 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. (Example shown)
b. Put the matching marks on a line extending from the knock pin
hole (B) position of camshaft sprocket (INT) (2). (Example
shown)
 Put the marks on the visible position with it installed to the
camshaft.
5. Install camshaft.
 Distinction between camshaft (INT and EXH) is performed with
the different shapes of rear end.
 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.

6. Install the camshaft sprocket (INT) to the camshaft (INT) with the
following procedure.
a. Align the matching mark (A) put according to step “4”. Securely
align the knock pin and the pin hole, and then install them.
b. Temporarily tighten the bolt on the front side of camshaft (INT)
(1).
7. Put a thick shop cloth (B) to the lower surface, and then set the
tools to the bolt camshaft (INT) (1).
8. Tighten the mounting bolt.
CAUTION:
Hold the camshaft hexagonal part (A), and then secure the
camshaft.
9. Return the camshaft (INT) to the cylinder head carefully.
10. Install the camshaft (EXH) to the camshaft sprocket (EXH) (2)
while aligning the matching make (marked when timing chain is
removed) (A) and the matching mark (stamp) (B) of camshaft
sprocket (EXH).
 If the positions of knock pin and pin groove are not aligned,
move the camshaft (EXH) slightly to correct these positions.

chain is removed) and each camshaft sprocket matching
mark are in the correct location.
12. Install camshaft brackets (No. 2 to 5) aligning the identification
marks on upper surface as shown.
 Install so that identification mark can be correctly read when
viewed from the INT side.

14. Install timing chain with the following procedure.
 Install by aligning matching marks on each sprocket and tim-
ing chain.
 If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
 Check matching mark position of each sprocket and tim-
ing chain again after installing the timing chain, keep
matching marks aligned by holding them with a hand.
 To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
15. Install timing chain tension guide (2) and timing chain slack
guide (1).
16. Install chain tensioner (1).
 Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.
 Securely pull out the stopper pin after installing the chain ten-
sioner.
17. Check matching mark position of timing chain and each sprocket again.

18. Pull out the stopper pin (A), and then apply the tension to the
timing chain by rotating the crankshaft pulley clockwise slightly.
19. Return the camshaft sprocket (INT) in the most retarded position with the following procedure.
a. Remove the stopper pin (A) from the camshaft sprocket (INT).
b. Turn the crankshaft slowly clockwise and return the camshaft sprocket (INT) to the most retarded angle
position.
 When first turning the crankshaft the camshaft sprocket (INT)
will turn. Once it is turned more, and the vane (camshaft) also
turns, then it has reached the most retarded angle position.
 The most retarded angle position can be checked by seeing if
the stopper pin groove (A) is shifted clockwise.
 After spinning the crankshaft slightly in the counterclockwise
direction, you can make sure the lock pin has joined by seeing
if the vane (camshaft) and the sprocket move together.
20. Install the front oil seal to the front cover. Refer to EM-78, "
FRONT OIL SEAL : Removal and Installation"
