g. After installing rear timing chain case, check the surface height difference between the following parts on the oil pan (upper)
mounting surface.
If not within the standard, repeat the installation procedure.
3. Install water pump with new O-rings. Refer to CO-22, "
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 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 a stopper pin. Standard
Rear timing chain case to cylinder block: –0.24 to 0.14 mm (–0.009 to 0.006 in)
SEM943G
Camshaft dowel pin hole (intake side): At cylinder head upper face side in each bank.
Camshaft dowel pin (exhaust side) : At cylinder head upper face side in each bank.
Crankshaft key : At cylinder head side of right bank.

b. Install timing chains (secondary) and camshaft sprockets.
Align the mating marks on timing chain (secondary) (gold link)
with the ones on intake and exhaust camshaft sprockets
(punched), and install them.
NOTE:
Mating marks for intake camshaft sprocket are on the back
side of camshaft sprocket (secondary).
There are two types of mating marks, 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.
c. After confirming the mating marks are aligned, tighten camshaft sprocket mounting bolts.
Secure camshaft using a wrench at the hexagonal portion to
tighten mounting bolts. Right bank : Use circle type.
Left bank : Use oval type.

d. Pull stopper pins out from timing chain tensioners (secondary).
6. Install tension guide.
7. Install timing chain (primary) as follows:
a. Install crankshaft sprocket.
Make sure the mating marks on crankshaft sprocket face the
front of the engine.
b. Install timing chain (primary).
Install timing chain (primary) so the mating mark (punched) on
camshaft sprocket 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).
CAUTION:
Do not overtighten slack guide mounting bolts. It is normal
for a gap to exist under the bolt seats when mounting bolts
are tightened to the specification.
9. Install the timing chain tensioner (primary) with the following procedure:
a. Pull plunger stopper tab up (or turn lever downward) so as to remove plunger stopper tab from the rachet of plunger.
NOTE:
Plunger stopper tab and lever are synchronized.
b. Push plunger into the inside of tensioner body.
c. Hold plunger in the fully compressed position by engaging plunger stopper tab with the tip of ratchet.
d. To secure lever, insert stopper pin through hole of lever into ten- sioner body hole.
The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
