c. Put a paint mark (B) on crankshaft pulley, mating with any one of
six easy to recognize angle marks (A) on crankshaft bolt flange
(1).
d. Turn another 60 degrees clockwise (angle tightening).
• Check the tightening angle with movement of one angle mark.
10. Check that crankshaft turns smoothly by rotating by hand clockwise.
11. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-12, "Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

a. Rotate crankshaft pulley (2) clockwise and align TDC mark
(without paint mark) (A) to timing indicator (1) on front cover.
b. Check that the matching marks on each of the camshaft sprock-
ets are in the position as shown.
• If not, rotate crankshaft pulley one more turn to align matching
marks to the positions as shown.
c. Paint matching marks (A) on the timing chain links.
4. Remove crankshaft pulley. Refer to
5. Remove front cover. Refer to
6. Secure the plunger of chain tensioner in the fully compressed position. Then, loosen the timing chain ten-
sion.
a. Fully push down the lever (B) of chain tensioner (2) from the
plug hole, and then insert the stopper pin (A) into the body side
hole and secure the lever at the lowest position.
• The tab is released by fully pushing the lever down. As a
result, the plunger (1) can be moved.
NOTE:
Hexagonal wrench [2.5 mm (0.098 in)] is used for a stopper pin
as an example.
CAUTION:
The stopper pin must use a shape that cannot fall in the
front cover if dropped.
b. Turn the crankshaft pulley (2) counterclockwise with the cam-
shaft (EXH) (1) held. Apply the tension to the timing chain, and
then push the plunger into the inside of chain tensioner.
CAUTION:
Hold the camshaft hexagonal part (A), and then secure the
camshaft.

c.
Pull out the stopper pin (A) of chain tensioner (2) side from plug
hole. Lift the lever (B) up to align its hole position with the hole of
the body.
• When the lever hole (C) is aligned with the body hole position,
the plunger (1) is secured.
• 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.
d. Insert the stopper pin into the body hole through the lever hole, and then secure the lever at the upper
position.
7. Remove timing chain.
8. 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.
9. 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).
• Loosen the bolts in several steps, and then remove them.
(D) : Front cover has been removed for clarity.
