b. Make sure that intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
NOTE:
When only timing chain (primary) is removed, rocker cover does

supporting point for suitable puller.
c. Place suitable puller tab on holes of crankshaft pulley, and pull
crankshaft pulley through.
CAUTION:
Do not put suitable puller tab on crankshaft pulley periph-
ery, as this will damage internal damper.

smoothly.
13. For the following operations, perform steps in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluid leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/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 exhaust gases, or any oil/fluids including
engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

e. Tighten mounting bolts in numerical order as shown in the fig-
ure.

There are two types of mounting bolt. Refer to the following
for locating bolts.
f. After all bolts tightening, retighten them to the specified in
numerical order as shown in the figure.

If liquid gasket protrudes, wipe it off immediately.
g. After installing rear timing chain case, check surface height dif-
ference between the following parts on the oil pan (upper)
mounting surface.

If not within standard, repeat the installation procedure.
3. Install water pump with new O-rings. Refer to CO-46, "
WATER PUMP" .
4. Make sure that dowel pin hole, dowel pin and crankshaft key are
located as shown in the figure. (No. 1 cylinder at compression
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.
CAUTION:
Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore big
dia. side).
5. Install timing chain (secondary) and camshaft sprockets (INT and EXH) as follows:
CAUTION:
Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions
repeatedly during the installation process.Bolt length: Bolt position

TIMING CHAIN

a. Push plunger of chain tensioner (secondary) and keep it
pressed in with stopper pin.
b. Install timing chain (secondary) and camshaft sprockets (INT
and EXH).

Align the mating marks on timing chain (secondary) (gold link)
with the ones on camshaft sprockets (INT and EXH)
(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 mark, circle and oval types.
They should be used for the right and left banks, respec-
tively.

Align dowel pin and pin hole on camshafts with the groove
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 on the back side of
camshaft sprocket, and install them.

On the exhaust side, align dowel pin on camshaft front end
with pin groove on camshaft sprocket, and install them.

In case that positions of each mating mark and each dowel
pin are not fit on mating parts, make fine adjustment to the position holding the hexagonal portion on
camshaft with wrench or equivalent.

Mounting 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
easier, make a mating mark on the top of sprocket teeth and
its extended line in advance with paint.

tighten mounting bolts.
d. Pull stopper pins out from timing chain tensioners (secondary).
6. Install tension guide.
7. Install timing chain (primary) as follows:

TIMING CHAIN


Install timing chain (primary) so the mating mark (punched) on
camshaft sprocket (INT) is aligned with the pink link on timing
chain, while the mating mark (notched) on crankshaft
sprocket is aligned with the orange one on timing chain, as
shown in the figure.

When it is difficult to align mating marks of timing chain (pri-
mary) with each sprocket, gradually turn camshaft using
wrench on the hexagonal portion to align it with the mating
marks.

During alignment, be careful to prevent dislocation of mating
mark alignments of timing chains (secondary).
8. Install internal chain guide, slack guide and timing chain ten-
sioner (primary).
