FUEL INJECTOR AND FUEL TUBE
Revision: 2006 January2006 M35/M45
CAUTION:
Handle O-ring with bare hands. Do not wear gloves.
Lubricate O-ring with new engine oil.
Do not clean O-ring with solvent.
Make sure that O-ring and its mating part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.
Insert new O-ring straight into fuel tube. Do not decenter or twist it.
Insert fuel feed damper straight into fuel tube (RH).
Tighten mounting bolts evenly in turn.
After tightening mounting bolts, make sure that there is no gap between flange and fuel tube (RH).
2. Install new O-rings to fuel injector paying attention to the following caution.
CAUTION:
Upper and lower O-ring are different. Be careful not to confuse them.
Handle O-ring with bare hands. Never wear gloves.
Lubricate O-ring with new engine oil.
Do not clean O-ring with solvent.
Make sure that O-ring and its mating part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.
Insert O-ring straight into fuel injector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector.
Insert clip so that “protrusion A” of fuel injector matches “cut-
out A” of clip.
CAUTION:
Do not 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
“cutout B” of clip.
Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.
Make sure that protrusions of fuel injectors are aligned with
cutouts of clips after installation.
4. Install spacers on intake manifold (lower).
5. Install fuel tube and fuel injector assembly to intake manifold (lower).
CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts. Fuel tube side : Black
Nozzle side : Green

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as follows: (Unless otherwise indicated, the installation to the
engine side and centralized under-floor piping side is exactly alike.)
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.
Engine side:
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.
Centralized under-floor piping side:
Visually confirm that the two retainer tabs are connected to the connector.
CAUTION:
Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick con-
nector.
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 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.
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:
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-30, "
OIL PUMP" .
