2. Install fuel injector (4) to fuel tube (1) with the following proce-
dure:
a. Insert clip (2) into clip groove (F) on fuel injector. • Insert clip so that protrusion (G) of fuel injector matches cut-
out (D) of clip.
CAUTION:
• Never reuse clip. Replace it with a new one.
• Be careful to keep clip from interfering with O-ring. Ifinterference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached. • Insert it while matching it to the axial center.
• Insert fuel injector so that protrusion (B) of fuel tube matches
cut-out (C) of clip.
• Make sure that fuel tube flange (A) is securely fixed in flange
fixing groove (E) on clip.
c. Make sure that installation is complete by making sure that fuel injector does not rotate or come off.
3. Set fuel tube and fuel injector assembly at its position for installation on cylinder head. CAUTION:
Be careful not to let tip of injector nozzle interfere with other parts.
4. Tighten bolts in numerical order as shown.
5. 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 sure 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.

7. Remove camshaft position sensor (PHASE) from camshaft bracket. CAUTION:
• Handle carefully to avoid dropping and shocks.
• Never disassemble.
• Never allow metal powder to adhere to magnetic part at sensor tip.
• Never place sensor in a location wher e it is exposed to magnetism.
8. Put matching marks (A) on the camshaft sprocket (INT) (2) and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2). • Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
• Never rotate crankshaft or camshaft while timing chainis removed. It causes interference between valve and
piston.
• Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then remove the camshaft bracket.
CAUTION:
• Be careful not to damage the mating surface.
• A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
