●

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).

TIMING CHAIN

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 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 ratchet 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.

e.

Install timing chain tensioner (primary).

●

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).

f.

Pull out stopper pin after installing, and then release plunger.

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

11. Install new O-rings on rear timing chain case.

12. Install new front oil seal on front timing chain case.

●

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. 

●

Using suitable drift, press-fit oil seal until it becomes flush with
front timing chain case end face.

●

Make sure the garter spring is in position and seal lip is not
inverted.

13. Install water pump cover and chain tensioner cover to front timing chain case.

●

Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 (

—

)] to front timing chain case as

shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS"

 .

14. Install front timing chain case as follows:

a.

Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000 (

—

)] to front timing chain case back side as

shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-46, "RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS"

 .

b.

Install front timing chain case as to fit its dowel pin hole together dowel pin on rear timing chain case.

c.

Tighten mounting bolts to the specified torque in numerical order
as shown in the figure.

●

There are two types of mounting bolts. Refer to the following
for locating bolts.

d.

After all bolts are tightened, retighten them to the specified
torque in numerical order shown in the figure.

CAUTION:

Be sure to wipe off any excessive liquid gasket leaking on surface mating with oil pan (upper).

e.

After installing front timing chain case, check the surface height
difference between the following parts on the oil pan (upper)
mounting surface.

●

If not within standard, repeat the installation procedure.

15. Install right and left valve timing control covers as follows:

: 1, 2

 : 25.5 - 31.3 N·m (2.6 - 3.2 kg-m, 19 - 23 ft-lb)
