TIMING CHAIN

3. Install timing chains (secondary) and camshaft sprockets as follows:

CAUTION:

Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions

repeatedly during the installation process.

a. Push plunger of timing chain tensioner (secondary) and keep it

pressed in with stopper pin.

b. Install timing chains (secondary) (8) and camshaft sprockets

(INT (1) and EXH (9)).

• Left bank mating marks (6)

• Align the timing chain mating marks (secondary) (2) (blue

color link) with the ones on camshaft sprockets (INT and EXH)

(4), (5), (7) and (10) (punched), and install them.

NOTE:

• Mating marks for camshaft sprocket (INT) are on the back

side of camshaft sprocket (secondary).

• There are two types of mating marks, circle (7), (10) and

oval (4), (5) types. They should be used for the right and left

banks, respectively.

• Align dowel pin (3) and pin hole on camshafts with the groove

(11) and dowel pin on sprockets, and install them.

• On the intake side, align pin hole on the small diameter side of

the camshaft front end with dowel pin (3) on the back side of

camshaft sprocket, and install them.

• On the exhaust side, align dowel pin on camshaft front end

with pin groove (11) on camshaft sprocket, and install them.

• In case that positions of each mating mark and each dowel pin

do not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on cam-

shaft with wrench or equivalent.

• Bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is enough to

prevent the dislocation of dowel pins.

• It may be difficult to visually check the dislocation of mating

marks during and after installation. To make the matching eas-

ier, make a mating mark on the top of sprocket teeth and its

extended line in advance with paint.

Right bank

: Use circle type (7) and (10).

Left bank

: Use oval type (4) and (5).

c. After confirming the mating marks are aligned, tighten camshaft

sprocket bolts.

• Secure camshaft using wrench at the hexagonal portion to

tighten bolts.

d. Pull stopper pins out from timing chain tensioners (secondary).

4. Install tension guide.
5. Install timing chain (primary) as follows:
a. Install crankshaft sprocket.

• Make sure the mating marks on crankshaft sprocket face the

front of engine.

TIMING CHAIN

b. Install the primary timing chain.

• Water pump (G).

• Install primary timing chain so the mating mark punched (B) on

camshaft sprocket is aligned with the blue link (A) on the tim-

ing chain, while the mating mark notched (E) on the crankshaft

sprocket (D) is aligned with the copper link (F) on the timing

chain, as shown.

• When it is difficult to align mating marks (A) with (B) and (E)

with (F) of the primary timing chain with each sprocket, gradu-

ally turn the camshaft using a wrench on the hexagonal por-

tion to align it with the mating marks.

• During alignment, be careful to prevent dislocation of mating

mark alignments of the secondary timing chains.

6. Install internal chain guide, slack guide and timing chain ten-

sioner (primary).

Do not overtighten slack guide bolts. It is normal for a gap

to exist under the bolt seats when bolts are tightened to

specification.

• When installing timing chain tensioner (primary), push in plunger and keep it pressed in with stopper pin.

• Remove any dirt and foreign materials completely from the back and the mounting surfaces of timing

chain tensioner (primary).

• After installation, pull out stopper pin.

7. Make sure again that the mating marks on camshaft sprockets and timing chain have not slipped out of

alignment.

8. Install front timing chain case. Refer to 

EM-51, "Removal and Installation"

.

INSPECTION AFTER INSTALLATION

• Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are

lower than required quantity, fill to the specified level. Refer to 

MA-16, "For North America"

.

• Run engine to check for unusual noise and vibration.

NOTE:

If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide

may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop

after hydraulic pressure rises.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oil/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to

specified level if necessary.

• Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
