INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
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.
• Warm up engine thoroughly to make sure there is no leak age 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.

5. Check matching mark position of timing chain and each sprocket again.
6. Pull out the stopper pin (A), and then apply the tension to the
timing chain by rotating the crankshaft pulley clockwise slightly.
7. 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 t he 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 t he 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.
8. Install the front oil seal to the front cover. Refer to EM-71, "

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.

• Attach the rubber nozzle narrowed to the top of the air gun to
prevent air leakage from the oil hole. Securely apply the air
pressure to the oil hole (A).
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 wi th 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) (1) lightly with a plastic hammer.
• If the camshaft sprocket (INT) (1) is not rotated counterclock- wise 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 pressu re and the holding procedure of camshaft (INT).
f. Insert the stopper pin (A) into the stopper pin holes in the cam- shaft sprocket (INT) (1) and lock in the most advanced angle
position.
CAUTION:
No load is exerted on the stop per 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: approximately 15
mm (0.59 in)].
