FUEL INJECTOR AND FUEL TUBE
c. Align center to insert quick connector straightly into fuel tube. • Insert quick connector to fuel tube until the top spool on fueltube is inserted completely and the 2nd level spool is posi-
tioned slightly below quick connector bottom end.
CAUTION:
• Hold “A” position shown when inserting fuel tube into
quick connector.
• Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
• Insert until you hear a “click” sound and actually feel
the engagement.
• To avoid misidentification of engagement with a similar sound, be sure to pe rform the next step.
d. Before clamping fuel feed hose with hose clamp, pull quick connector hard by hand holding “A” position.
Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
e. Install quick connector cap (1) to quick connector connection. • Install quick connector cap with the side arrow facing quick
connector side (fuel feed hose side).
CAUTION:
• Make sure that the quick connector and fuel tube are
securely engaged with the quick connector cap mount-
ing groove.
• Quick connector may not be connected correctly if quick connector cap cannot be installed easily. Remove
the quick connector cap, and then check the connection
of quick connector again.
f. Install fuel feed hose to hose clamp.
7. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, make sure
there are no fuel leaks at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start the engine. With engine speed increased, make su re again that there are no fuel leaks at connection
points.
CAUTION:
Never touch the engine immediately after it is stopped, as the engine becomes extremely hot. KBIA0272E

9. Tighten crankshaft pulley bolt with the following procedure: • 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
(1).
d. Turn another 60 degrees clockwise (angle tightening). • Check the tightening angle with movement of one angle mark.
10. Make sure that crankshaft turns smoothly by rotating by hand clockwise.
11. Installation of the remaining components is in the reverse order of removal.

Handle it carefully and avoid impacts.
11. Remove camshaft sprocket (EXH) (1). CAUTION:
• Hold the camshaft hexagonal part (A), and then secure the

• 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 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 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 sprocke t (INT) counterclockwise [the direction shown by the
arrow ( )].
• Perform the work while applying the air pressure to the oil hole. AWBIA0105ZZ

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. Hold the camshaft hexagonal part (A), to secure the camshaft and tighten the bolt.
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. PBIC3701E
