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.

Removal and Installation
INFOID:0000000004307143
CAUTION:
The rotating direction indicated in the text indicates all directions seen from the engine front.
REMOVAL 1. Remove front RH wheel. Refer to WT-7, " Rotation " .
2. Remove front fender protector (RH). Refer to EI-24, " Removal and Installation " .
3. Drain engine oil. Refer to LU-17, " Changing Engine Oil " .
CAUTION:
Perform this step when engine is cold.
4. Remove the following parts. • Rocker cover: Refer to EM-153, " Component " .
• Drive belt: Refer to EM-136, " Removal and Installation " .
• Water pump pulley: Refer to CO-43, " Component " .
• Ground cable (between engine bracket (RH) and radiator core support)
5. Support the bottom surface of engine using a transmission jack, and then remove the engine bracket and insulator (RH). Refer to EM-195, " Component " .
6. Set No. 1 cylinder at TDC on its compression stroke with the following procedure:
a. Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front cover.
b. At the same time, make sure that the cam noses of the No.1 cyl- inder are located ( ) as shown.
• If not, rotate crankshaft pulley one revolution (360 degrees) and align as shown.
7. Hold crankshaft pulley (1) using suitable tool (A) loosen crank- shaft pulley bolt, and locate bolt seating surface at 10 mm (0.39
in) from its original position.
CAUTION:
Never remove the crankshaft pulley bolt as it will be used as
a supporting point for the pulley puller.
16. Oil pump drive chain 17. Camshaft sprocket (INT) 18. Timing chain tension guide
19. O-ring 20. Chain tensioner (for oil pump)
A. Refer to EM-161 B. Refer to
EM-170 C : White paint mark (Not use for service)

Component " .
NOTE:
When crankshaft sprocket, oil pump sprocket and other related parts are not removed, this step is unnec-
essary.
10. Remove intake valve timing control solenoid valve.
11. Remove drive belt auto-tensioner.
12. Loosen bolts in reverse order as shown.
13. Cut liquid gasket by prying the position ( ) shown, and then remove the front cover.
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
the position not specified.
14. Remove front oil seal from front cover. • Lift up front oil seal using a suitable tool.
CAUTION:
Be careful not to damage front cover. Tool number : KV11103000 ( — )

15. Push in timing chain tensioner plunger.
16. Insert a stopper pin (A) into the body hole to retain the plunger in collapsed position.
NOTE:
Use approximately 1.5 mm (0.059 in) diameter hard metal pin as
a stopper pin.
17. Remove timing chain tensioner (1).
18. Remove timing chain slack guide (2), timing chain tension guide (3) and timing chain (1).
CAUTION:
Never rotate each crankshaft and camshaft individually
while timing chain is re moved. It causes interference
between valve and piston.

• Check timing chain and oil pump drive chain for cracks (A) and any
excessive wear (B) at the roller links of timing chain.
• Replace timing chain and/or oil pump drive chain if necessary.
INSTALLATION NOTE:
The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.
1. Make sure that crankshaft key points are aligned.
NOTE:
*: There are two outer grooves in camshaft spro cket (INT). The wider one is a matching mark.
2. If the timing chain tension guide (front cover si de) is removed, install it to the front cover.
CAUTION:
Check the joint condition by sound or feeling.
3. Install crankshaft sprocket (2), oil pump sprocket (3) and oil pump drive chain (1).
• Install it by aligning matching marks on each sprocket and oil pump drive chain.
• If these matching marks are not aligned, rotate the oil pump
shaft slightly to correct the position.
CAUTION:
Check matching mark position of each sprocket after
installing the oil pump drive chain. PBIC3171J
