TIMING CHAIN
Revision: 2004 November 2004 FX35/FX45
1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
2. Install camshaft sprockets.

Install onto correct side by checking with identification mark
on surface.

Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)

Lock the hexagonal part of camshaft in the same procedure
as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.

Install each crankshaft sprocket so that its flange side (the
larger diameter side without teeth) faces in the direction
shown in the figure.
NOTE:
The same parts are used but facing directions are different.Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key
: At cylinder head side of left bank

4. Install timing chains and related parts.

Align the mating mark on each sprocket and timing chain for installation.
CAUTION:
For the above reason, after the mating marks are aligned, keep them aligned by holding them
with a hand.
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.

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" .

7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.

If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.

Apply new engine oil to both oil seal lip and dust seal lip.

Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.

Using suitable drift, press fit until the height of front oil seal is
level with the mounting surface.

Make sure the garter spring is in position and seal lips not
inverted.
9. Install chain tensioner cover to front cover.

Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the
figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
10. Install front cover as follows:

a. Install new O-rings onto cylinder heads (right and left bank) and
cylinder block.
b. Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the fig-
ure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
c. make sure again that the mating marks on timing chain and that
on each sprocket are aligned. Then, install front cover.
CAUTION:
Be careful to avoid interference with the front end of oil
pump drive spacer. Such interference may damage front oil
seal.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.

There are four type mounting bolts.
e. After all bolts are tightened, retighten them in numerical order as shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking onto surface mating with oil pan.
11. Install intake valve timing control cover as follows:
a. At the back of intake valve timing control cover, install new seal rings (three for each bank) to the area to
be inserted into camshaft sprocket (INT).
CAUTION:
Do not spread seal ring excessively to avoid breaks and deformation.

OIL PAN AND OIL STRAINER" .
14. Install crankshaft pulley as follows:
a. Fix crankshaft with ring gear stopper [SST: J-45476].
b. Install crankshaft pulley, taking care not to damage front oil seal.

Install according to dowel pin of oil pump drive spacer.

Lightly tapping its center with plastic hammer, insert pulley.
CAUTION:
Do not tap pulley on the side surface where belt is installed (outer circumference).
c. Apply engine oil onto threaded parts of crankshaft pulley bolt and seating area.
d. Tighten crankshaft pulley bolt.
e. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.

f. Further tighten by 90 degrees. (Angle tightening)

Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns
smoothly.
16. Install in the reverse order of removal after this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, lubrications and working fluid. If less than
required quantity, fill to the specified level.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil and working
fluid, fuel and exhaust gas.

Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.

After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to
specified level, if necessary.

ENGINE OIL LEVEL
NOTE:
Before starting engine, check engine oil level. If engine is already started, stop it and allow 10 minutes before
checking.
1. Put vehicle horizontally.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and make sure engine oil level is within the
range shown in the figure.
4. If it is out of range, adjust it.
NOTE:
When checking engine oil level, insert oil level gauge with its tip
aligned with oil level gauge guide on cylinder head. (In figure, air
cleaner case and air duct are removed.)
ENGINE OIL APPEARANCE

Check engine oil for white turbidity or heavy contamination.

If engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Water pump cover

Chain tensioner cover

Intake valve timing control cover and intake valve timing control solenoid valve

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Mating surface between front timing chain case and rear timing chain case

Mating surface between rear timing chain case and cylinder block and cylinder head

Crankshaft oil seal (front and rear)
