O• Handle O-rings with bare hands only. Do not wear gloves.
• Do not clean O-rings with solvent.
• Make sure that O-ring and its mating part are free of foreign material.
• Be careful not to scratch O- rings during installation.
• Do not twist or stretch the O-ring. If the O-ring was stretched while it is attached, do not insert it
into the fuel tube immediately.
2. Install the fuel injector (5) into the fuel tube (1) with the following procedure:
(2): O-ring (black)
(4): O-ring (green)
a. Insert the new clip (3) into the clip mounting groove (F) on fuel injector (5).
• Insert the clip (3) so that prot rusion (E) of fuel injector (5)
matches cutout (C) of the clip (3).
CAUTION:
• Do not reuse clip (3), replace it with a new one.
• Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector (5) into fuel tube (1) with clip (3) attached. • Insert fuel injector (5) so that protrusion (A) of fuel tube (1)
matches cut-out (B) of the clip (3).
• Check that fuel tube flange (G) is securely fixed in flange
groove (D) on the clip (3).
c. Check that installation is comple te by checking that fuel injector
(5) does not rotate or come off.
3. Install fuel tube and fuel injector assembly with the following procedure.
a. Insert the tip of each fuel injector into intake manifold.
b. Tighten the bolts to specification in the numerical order as shown.
CAUTION:
After properly connecting fu el tube assembly to injector
and fuel hose, check co nnection for fuel leaks.
4. Connect the fuel hose quick connector.
a. Make sure no foreign substances are deposited in and around the fuel tube and quick connector, and there is no damage to them.
b. Thinly apply new engine oil around the fuel tube tip end. Fuel tube side : Black
Nozzle side : Green

c. Align center to insert quick connector straight onto fuel tube.
d. Insert fuel tube into quick connector (1) until the top spool (B) on fuel tubes is inserted completely and the second level spool (C)
is positioned slightly below the quick connector bottom end.
CAUTION:
• Hold at position (A) as show n, when inserting the fuel
tube into the quick connector.
• Carefully align to center to avoid inclined insertion to pre-
vent damage to the O-ring inside the quick connector.
• Insert the fuel tube until you hear a “click” sound and
actually feel the engagement.
• To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
• Do not reuse O-ring.
e. Before clamping the fuel hose with the hose clamp, pull the quick connector hard by hand, holding at the
(A) position, as shown. Make sure it is completely engaged (connected) so that it does not come off of the
fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).
f. Install quick connector cap (1) over fuel hose side (B) and fuel tube side (A).
NOTE:
Direct arrow mark on quick connector cap (1) to fuel hose side.
5. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Make sure there are no fuel leaks at connections as follows:
1. Apply fuel pressure to fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at connections.
2. Start the engine and rev it up and check for fuel leaks at connections. • Perform procedures for “Throttle Valve Closed Posi tion Learning” after finishing repairs. Refer to EC-
178, "Work Procedure".
• If electric throttle control actuator is replaced, perform procedures for “Idle Air Volume Learning” after
finishing repairs. Refer to EC-179, "Work Procedure"
.
WARNING:
Do not touch engine immediately after stopping as engine is extremely hot.
NOTE:
Use mirrors for checking on connections out of the direct line of sight.

Camshaft Runout
1. Put the camshaft on a V-block supporting the No.2 and No.5 journals.
CAUTION:
Do not support the No. 1 journal (on the side of the cam-
shaft sprocket) because it has different diameter from the
other four locations.
2. Set the dial gauge (A) vertically on the No.3 journal.
3. Turn camshaft in one direction by hand, and measure the cam- shaft runout on the dial gauge total indicator reading.
Camshaft Cam Height
1. Measure the camshaft cam height using suitable tool (A).

he camshaft journal using suitable
tool (A).
Inner Diameter of Camshaft Bracket
• Tighten the camshaft bracket bolts to the specified torque following
the tightening pattern as shown.
• Using inside micrometer (A), measure inner diameter of camshaft bracket (1).
Calculation of Camshaft Journal Clearance
• (Journal clearance) = (inner diameter of camshaft bracket) – (outer diameter of camshaft journal)
• When out of the specified range above, replace either or both the camshaft and the cylinder head assembly.
NOTE:
Inner diameter of the camshaft bracket is manufac tured together with the cylinder head. If the camshaft
bracket is out of specification, replace the whole cylinder head assembly.
