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. If
interference 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 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.
3 : O–ring (black)
5 : O–ring (green)

TIMING CHAIN
4. Hold the WAF part of oil pump shaft (A), and then tighten the oil
pump sprocket bolt.
CAUTION:
• Secure the oil pump shaft with the WAF part (A).
• Never loosen the oil pump sp rocket bolt by tightening the
oil pump drive chain.
5. Install chain tensioner (for oil pump) (1). 1. Fix the plunger at the most compressed position using a
stopper pin (A), and then install it.
2. Securely pull out ( ) the stopper pin after installing the chain tensioner (for oil pump).
3. Check matching mark position of oil pump drive chain and each sprocket again.
6. Align the matching marks of each sprocket with the matching marks of timing chain.
NOTE:
*: There are 2 outer grooves in camshaft sprocket (INT). The
wider one is a matching mark.
• If these matching marks are not aligned, rotate the camshaft slightly by holding the hexagonal portion to correct the posi-
tion.
CAUTION:
Check matching mark position of each sprocket and timing
chain again after instal ling the timing chain.

gasket application.
• Be sure to wipe off any excessive liquid gasket leaking.
NOTE:
Installation position of bolts is as shown.
16. Install crankshaft pulley using the following procedure.
a. Install crankshaft pulley. CAUTION:
• Never damage front oil seal lip section.
• If needed use a plastic hammer, tap on its cente r portion (not circumference) to seat crankshaft
pulley.
b. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
c. Secure crankshaft pulley (1) using Tool (A).
