FUEL INJECTOR AND FUEL TUBE
Revision: 2005 July 2005 FX

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as the following: (Excepting to confirm whether or not there is quick connector cap, perform same procedure for the side of centralized under-floor piping as well.)
a. Make sure no foreign substances are deposited in and around fuel tube and quick connector, and no dam- age on them.
b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube.

Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:

Hold “A” position as shown in the figure when inserting
fuel tube into quick connector.

Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.

Insert until you hear a “click” sound and actually feel the
engagement.

To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
d. Pull quick connector by hand holding “A” position. Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
e. Install quick connector cap on quick connector connection. (on engine side only).
CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed correctly. Check connection again.
f. Install fuel feed hose to hose clamps.
7. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1. Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2. Start engine. With engine speed increased, check again for fuel leakage at connection points. CAUTION:
Do not touch engine immediately after stopped, as engine becomes extremely hot. 1st step : 10.1 N·m (1.0 kg-m, 7 ft-lb)
2nd step : 23.5 N·m (2.4 kg-m, 17 ft-lb)

TIMING CHAIN
Revision: 2005 July 2005 FX
NOTE:
To remove timing chain and related parts, start with those on left bank. The procedure for removing parts
on right bank is omitted because it is the same as that for left bank.
a. Press tab in the direction of arrow (or turn lever in the direction of arrow) to unlock the locking with the groove that stops ten-
sioner plunger from returning.

Lightly press tensioner plunger to release the tension of
spring for this operation.
b. Push in tensioner plunger to align the hole on lever and that on pump main body.

Pushing in tensioner too far does not allow the holes to align.
Therefore, push in plunger to the degree at which the start of
stopper groove and tab engages.
c. Insert stopper pin [hard wire with approx. 0.5 mm (0.020 in) diameter or similar tool] to fix plunger. With plunger fixed, remove chain tensioner.
17. Remove chain tension guide and timing chain slack guide.
18. Remove timing chain and crankshaft sprocket.
CAUTION:
After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
the piston head.
19. With hexagonal part of camshaft locked with wrench, loosen mounting bolts securing camshaft sprocket to remove camshaft
sprocket.
CAUTION:
Do not loosen mounting bolts with securing anything other
than the camshaft hexagonal portion or with tensioning the
timing chain.
20. Perform same procedure as for left bank, remove timing chain and related parts on right side.
21. Use scraper to remove all traces of old liquid gasket from front cover and opposite mating surfaces.

Remove oil liquid gasket from bolt hole and thread.
22. Use scraper to remove all trace of liquid gasket from chain tensioner cover and intake valve timing control covers.

4. Install timing chains and related parts.

Align the mating mark on each sprocket and timing chain for installation.
NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks are aligned, keep them aligned by holding them
with a hand.

Install slack guides and tension guides onto correct side by checking with identification mark on sur-
face.

Install chain tensioner with plunger fixed as described in its removal.
CAUTION:

Before and after the installation of chain tensioner, make sure that the mating mark on timing
chain is not out of alignment.

After installing chain tensioner, remove stopper pin to release tensioner. Make sure tensioner
is released.

To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.
5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
6. Install oil pump. Refer to LU-31, "
OIL PUMP" .
