c. After connecting, check that the connection is secure:
• Visually confirm that the two retainer tabs are connected to theconnector.
• With the fuel feed hose not fix ed to the clamp, pull quick con-
nector (A) hard by hand to check that the quick connector (A)
is not disconnected from the centralized underfloor piping (1)
and that the quick connector (1) is securely connected.
9. Installation of remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Check on Fuel Leaks
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there are no fuel leaks at connection points. Refer to.
NOTE:
Use mirrors for checking points out of clear sight.
2. Start the engine. With engine speed increased, check again that there are no fuel leaks at connection
points.
• Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
129, "Description".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-130, "
Description".
CAUTION:
Do not touch the engine immediately after stopping, as the engine becomes extremely hot.

b. Cut liquid gasket by prying the position ( ) as shown, and then
remove the front cover.
12. Remove front oil seal from front cover using a suitable tool. CAUTION:
Be careful not to damage the front cover.
13. Remove chain tensioner (1):
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. Thenthe 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, theplunger 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.
c. Insert the stopper pin (D) into the body hole through the lever hole, and then secure the lever at the upper position.
NOTE:
A hexagonal wrench of 2.5 mm (0.098 in) is used as a stopper pin (D).
d. Remove chain tensioner.
14. Remove the timing chain tension guide (2) and the timing chain slack guide (1).
15. Remove the timing chain (2). • Pull the timing chain slack toward the camshaft sprocket
(EXH) (1), and then remove the timing chain and start the
removal from camshaft sprocket (EXH) side.
CAUTION:
Do not rotate crankshaft or camshaft while timing chain is
removed. It causes interferen ce between valve and piston.
16. Remove the crankshaft sprocket and the oil pump drive:

• Secure crankshaft pulley with a suitable tool and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
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

10. Check that crankshaft turns smoothly by rotating by hand clockwise using suitable tool.
11. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels, includi ng engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
• Start engine. With engine speed increased, check again for fuel leaks 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 are no lea ks 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.

2. Remove camshaft sprocket (EXH) (1).
CAUTION:
• Hold the camshaft hexagonal pa rt (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.
3. 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 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.
• Put the camshaft sprocket (INT) in the most advanced position:
a. Remove camshaft bracket (No. 1) (1). NOTE:
Timing chain is present only for illustration purposes. Timing
chain is to be removed during removal procedure.
• 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 narrowed to the top of the air gun to prevent air leaks from the oil hole (A). Securely apply the air
pressure to the oil hole.
WARNING:
Eye protection should be worn as needed.
CAUTION:
• There are other oil holes in the side gr ooves. Do not use the incorrect oil holes.

• Be sure not to damage the oil pa
th 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 wipe d with a rag when applying air pressure.
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- nately.
• Finally rotate the sprocket of the camshaft sprocket (INT)
counterclockwise [the direction shown by the arrow ( )].
• Perform the work while continuously applying the air pressure to the oil hole.
• If the lock pin is not released, tap the camshaft sprocket (INT) lightly with a plastic hammer (A) using suitable tool.
• 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.
• Check that it is in the most advanced angle positi on by seeing if the stopper pin groove (A) and the stop-
per pin hole (B) are matched up as shown.
e. Stop applying air pressure and release the 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 falling out.
NOTE:
The stopper pin shows one example of a hexagonal wrench for
2.5 mm (0.098 in) [length of inse rted section: approximately15
mm (0.59 in)].
