FUEL INJECTOR AND FUEL TUBE
9. Remove fuel tube bolts.
• Loosen bolts in reverse order as shown.
10. Remove the fuel tube and fuel injector assembly. CAUTION:
• When removing, be careful to avoid any interference with fuel injector.
• Use a shop cloth to absorb any fuel leaks from fuel tube.
11. Remove fuel injector from the f uel tube with the following procedure:
a. Open and remove the clip.
b. Remove fuel injector from the fuel tube by pulling straight. CAUTION:
• Be careful about spilling fu el remaining in fuel tube.
• Be careful not to damage the fuel injector nozzle during removal.
• Never bump or drop fuel injector.
• Never disassemble fuel injector.
INSTALLATION
1. Install new O-rings to the fuel injector.
CAUTION:
• The upper and lower O-rings are different. Be careful not to confuse them.
• Handle O-ring with bare hands. Never wear gloves.
• Lubricate O-ring with new engine oil.
• Never clean O-ring with solvent.
• Make sure that the O-ring and its mati ng part are free of foreign material.
• Be careful not to scratch O-ring with tool or fingernails when installing.
• Do not twist or stretch O-ring. If O-ring was stretched while installing, never insert it into fuel
tube immediately.
• Insert O-ring straight into fuel tube. Never angle or twist it.

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.

15. 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.
16. Remove front oil seal from front cover. • Lift up front oil seal using a suitable tool.
CAUTION:
Be careful not to damage front cover.
17. Push in timing chain tensioner plunger.
18. 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.
19. Remove timing chain tensioner (1).
20. 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 removed. It causes interference
between valve and piston.

21. Press stopper tab (A) in the direction shown to push the timing
chain slack guide (B) toward timing chain tensioner (for oil
pump) (1).
• The slack guide (B) is released by pressing the stopper tab(A). As a result, the slack guide (B) can be moved.
22. Insert stopper pin (D) into tensioner body hole (C) to secure tim- ing chain slack guide (B).

(0.047 in) as a stopper pin.
23. Remove timing chain tensioner (for oil pump), if necessary.
24. Hold the WAF part of oil pump shaft (A), and t hen loosen the oil pump sprocket bolt and remove them.
CAUTION:
• Secure the oil pump shaft with the WAF part (A).
• Never loosen the oil pump sp rocket bolt by tightening the

• 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 pum p 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.
