TIMING CHAIN
12. Remove the timing chain tension guide (2) and the timing chain
slack guide (1).
13. Remove the timing chain (2). • Pull the looseness of timing chain toward the camshaft
sprocket (EXH) (1), and then remove the timing chain (2) and
start the removal from camshaft sprocket (EXH) (1) side.
CAUTION:
Never rotate crankshaft or camshaft while timing chain is
removed. It causes interferen ce between valve and piston.
14. Remove the crankshaft sprocket and the oil pump drive related parts with the following procedure.
a. Remove chain tensioner (1). • Pull out from the shaft (B) and spring fixing holes (A).
b. Hold the top of the oil pump s haft using the TORX socket (size:
E8), and then loosen the oil pump sprocket nut and remove it.
c. Remove the crankshaft sprocket (1), the oil pump drive chain (2), and the oil pump sprocket (3) at the same time.

3. Remove camshaft sprocket (EXH) bolt and 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 pist on in the following steps.
4. 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.
• The sprocket (C) and vane ( camshaft coupling) (B) are
designed to spin and move wi thin the range of a certain
angle.
• With the engine stopped and the vane in the most
retarded angle, it will not sp in 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 pi n will become damaged 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 groovefrom the front of camshaft thrust.
• Proceed all the way through step “e” with the air pressure on.

5. Remove camshaft sprocket (INT) bolt and camshaft sprocket
(INT) (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 pist on in the following steps.
6. 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.
7. Remove camshaft (EXH).
8. Remove camshaft (INT). CAUTION:
Never damage the signal plate of rear end.
9. Remove valve lifter. • Identify installation positions, and store them without mixing them up.
10. Remove intake valve timing control solenoid valve (1).
11. Remove the generator and bracket, if necessary, then remove the plug (2), washer and oil filter. Refer to SC-25, "
Removal and
Installation".
CAUTION:
Discard the washer, do not reuse.
INSTALLATION
1. Install the oil filter (1) and new washer (2). • The oil filter is assembled to the plug (3), and then install it tothe cylinder head.
CAUTION:
Do not reuse the washer, install a new washer.
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 incorr ect 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 camshaftsprocket 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 thecamshaft.
5. Install camshafts.
• Distinction between camshaft (INT and EXH) is performed withthe 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 camshaft brackets (No. 2 to 5) aligning the identification marks on upper surface as shown.
• Install so that identification mark can be correctly read whenviewed from the INT side.

INSPECTION AFTER REMOVAL
Oil Filter
• Make sure that there is no foreign material on the oil filter (1) and check it for clogging.
• Check the oil filter (1) for damage.
• If there is some damage, replace t he oil filter (1), the plug, and the
washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour- nals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on the dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If wear exceeds the limit, replace camshaft.
