CAUTION:
Do not overtighten slack guide mounting bolt. It is normal
for a gap to exist under the bolt seat when mounting bolt is
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 each sprocket and each 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.

b. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000] to intake valve timing control covers as shown in
the figure.
Use Genuine Liquid Gasket or equivalent.
c. Install new collared O-ring in front timing chain case oil hole (left
and right sides).
d. Being careful not to move seal rings from the installation grooves, align dowel pins on front timing chain
case with the holes to install intake valve timing control covers.
e. Tighten mounting bolts in numerical order as shown in the fig-
ure.
16. Install crankshaft pulley as follows:
a. Install crankshaft pulley, taking care not to damage front oil seal.

When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
b. Fix crankshaft with pulley holder [SST: KV10109300].
c. Tighten crankshaft pulley bolt.
d. Place a matching mark (A) on crank pulley (1) aligning with the
matching (B) of crank pulley mounting bolt (2). Tighten the bolts
90 degrees (one marks).

3. Remove front timing chain case, camshaft sprocket, timing chain and rear timing chain case. Refer to EM-
173, "TIMING CHAIN" .
4. Remove camshaft position sensors (PHASE) (right and left
banks) from cylinder head back side.
CAUTION:

Handle carefully to avoid dropping and shocks.

Do not disassemble.

Do not allow metal powder to adhere to magnetic part at
sensor tip.

Do not place sensors in a location where they are
exposed to magnetism.
5. Remove intake valve timing control solenoid valves.

Discard intake valve timing control solenoid valve gaskets and
use new gaskets for installation.
6. Remove camshaft brackets.

Mark camshafts, camshaft brackets and bolts so they are placed in the same position and direction for
installation.

Equally loosen camshaft bracket bolts in several steps in the
reverse order as shown in the figure.
7. Remove camshafts.
