• Insert new O-ring straight into fuel tube. Do not twist it.

6.

Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

After installing the fuel tubes, make sure there are no fuel leaks at the connections using the following steps.

1.

Apply fuel pressure to the fuel lines by turning ignition switch ON (with engine stopped). Then check for
fuel leaks at the connections.

2.

Start the engine and rev it up and check for fuel leaks at the connections.

WARNING:

Do not touch the engine immediately after stopping, as engine becomes extremely hot.
NOTE:
Use mirrors for checking on hidden points.

8.

Remove the oil pump drive spacer.
• Hold and remove the flat space of the oil pump drive spacer by

pulling it forward.

9.

Remove the oil pump. Refer to

LU-30, "Removal and Installation"

.

10. Remove the chain tensioner on the LH bank using the following steps.

NOTE:
To remove the timing chain and associated parts, start with those on the LH bank. The procedure for
removing parts on the RH bank is omitted because it is the same as that for the LH bank.

a.

Squeeze the return-proof clip ends using suitable tool and push
the plunger into the tensioner body.

b.

Secure the plunger using stopper pin.
• Stopper pin is made from hard wire approximately 1 mm (0.04

in) in diameter.

c.

Remove the bolts and chain tensioner.

WARNING:

Plunger, spring, and spring seat pop out when (squeezing)
return-proof clip without holding plunger head. It may
cause serious injuries. Always hold plunger head when
removing.

NOTE:
• Stop the plunger in the fully extended position by using the

return-proof clip (1) if the stopper pin is removed.

• Push the plunger (2) into the tensioner body while squeezing

the return-proof clip (1). Secure it using stopper pin (3).

11. Remove the timing chain tension guide and timing chain slack guide.

12. Remove the timing chain and crankshaft sprocket.

13. Loosen the camshaft sprocket bolts as shown and remove the

camshaft sprocket.
• A: Camshaft holding location

CAUTION:

To avoid interference between valves and pistons, do not
turn crankshaft or camshaft when timing chain is discon-
nected.

14. Repeat the same procedure to remove the RH timing chain and

associated parts.

TIMING CHAIN

Check for cracks and any excessive wear at link plates. Replace
chain if necessary.
• In the same way as for the LH bank, inspect the timing chain and

associated parts on the RH bank.

INSTALLATION

NOTE:
• The above figure shows the relationship between the mating mark on each timing chain and that of the cor-

responding sprocket, with the components installed.

• To install the timing chain and associated parts, start with those on the RH bank. The procedure for installing

parts on the LH bank is omitted because it is the same as that for installation on the RH bank.

1.

Make sure the crankshaft key and camshaft dowel pin RH bank
and camshaft dowel pin LH bank are facing in the direction
shown.

2.

Install the camshaft sprockets.
• Install the camshaft sprocket INT (VTC) (A) and camshaft

sprockets EXH (B) by selectively using the groove of the
dowel pin according to the bank. (Common part used for both
exhaust banks.)
NOTE:
Use the groove marked (R) for RH bank and (L) for LH bank.

• Lock the hexagonal part of the camshaft in the same way as

for removal, and tighten the bolts.

• A : Intake
• B = V: Exhaust

3.

Install the crankshaft sprockets for both banks.
• Install LH bank crankshaft sprocket (B) and RH bank crank-

shaft sprocket (C) so that their flange side (A) (the larger diam-
eter side without teeth) faces in the direction shown.
NOTE:
The same parts are used but facing directions are different.

4.

Install the timing chains and associated parts.
• Align the alignment mark on each sprocket and the timing chain for installation.

CAUTION:

• Before installing chain tensioner, it is possible to change the position of alignment mark on

timing chain and each sprocket. After the alignment marks are aligned, keep them aligned by
holding them by hand.

• Install the slack guides and tension guides onto the correct side by checking the identification mark on

the surface.

• Install the chain tensioner with the plunger locked in with the stopper pin.

CAUTION:

• Before and after the installation of the chain tensioner, make sure that the alignment mark on

the timing chain is not out of alignment.

• After installing the chain tensioner, remove the stopper pin to release the chain tensioner.

Make sure the chain tensioner is released.

• To avoid chain-link skipping of the timing chain, do not move crankshaft or camshafts until the

front cover is installed.

5.

In the same way as for the RH bank, install the timing chain and associated parts on the LH bank.

6.

Install the oil pump.

7.

Install the oil pump drive spacer as follows:
• Install so that the front mark on the front edge of the oil pump

drive spacer faces the front of the engine.

• Insert the oil pump drive spacer according to the directions of

the crankshaft key and the two flat surfaces of the oil pump
inner rotor.

• If the positional relationship does not allow the insertion, rotate

the oil pump inner rotor to allow the oil pump drive spacer to
be inserted.

8.

Install the front oil seal using suitable tool.

CAUTION:

Do not scratch or make burrs on the circumference of the
oil seal.

9.

Install the chain tensioner cover.
• Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-26, "Recommended Chemical Products and Sealants"

.

10. Install the front cover as follows:
a.

Install a new O-ring on the cylinder block.
