2. Hammer dowel pins (right and left) into front timing chain case
up to a point close to taper in order to shorten protrusion length.
3. 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 [outer diameter: 60 mm (2.36 in)], 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.
4. 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 Liquid Gasket or equivalent.
5. Install front timing chain case as follows:

the figure.
Use Genuine Liquid Gasket or equivalent.
b. Install new oil pan gasket.

Apply liquid gasket to oil pan gasket as shown in the figure.

Apply liquid gasket with tube presser [SST: WS39930000] to
top surface of oil pan (upper) as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
c. Install new O-rings on rear timing chain case.
d. Assemble front timing chain case as follows:
i. Fit lower end of front timing chain case tightly onto top face of oil
pan (upper). From the fitting point, make entire front timing chain
case contact rear timing chain case completely.
CAUTION:
Be careful that oil pan gasket is in place.
ii. Since front timing chain case is offset for difference of bolt holes,
tighten bolts temporarily with holding front timing chain case
from front and top as shown in the figure.
iii. Same as the step ii, insert dowel pin with holding front timing
chain case from front and top completely.

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

There are two types of mounting bolt. Refer to the following
for locating bolts.
f. After all bolts tightening, retighten them to the specified torque in
numerical order as shown in the figure.
6. Install engine mounting bracket (RH) and engine mounting insulator (RH). Refer to EM-223, "
ENGINE
ASSEMBLY" .
7. Remove jack which supports the oil pan (lower) bottom.
8. Remove oil pan (lower).
9. Install two mounting bolts in front of oil pan (upper) in numerical
order as shown in the figure.
10. Install oil pan (lower). Refer to EM-145, "
OIL PAN AND OIL STRAINER" .
11. Install right and left intake valve timing control covers as follows:
a. Install new seal rings in shaft grooves.
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-rings in front timing chain case oil holes
(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.M8 bolts : 1, 2

e. Tighten mounting bolts in numerical order as shown in the fig-
ure.
12. 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).
e. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns
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.
