29. Use a scraper to remove all traces of liquid gasket from water
pump cover, chain tensioner cover and intake valve timing con-
trol covers.
INSTALLATION
1. Install timing chain and related parts. Refer to EM-64, "TIMING CHAIN" .

3. Install front oil seal on front timing chain case.
Apply new engine oil to the oil seal lip and dust seal lip.
Install it so that each seal lip is oriented as shown in the fig-
ure.
Using a suitable drift [outer diameter: 60 mm (2.36 in)], press-
fit oil seal until it becomes flush with front timing chain case
end face.

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.
For bolt length and positions, refer to the step e.
iii. Same as the step ii, insert dowel pin with holding front timing chain case from front and top completely.

9. Install crankshaft pulley as follows:
a. Fix crankshaft using the ring gear stopper [SST: KV10117700 (J44716)].
b. 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).
c. Tighten crankshaft pulley bolt.
d. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
e. Further tighten by 90 degrees. (Angle tightening)
Check the tightening angle by referencing to the notches. The
angle between two notches is 90 degrees.
10. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns smoothly.
11. For the following operations, perform steps in the reverse order of removal. NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in the guide may gener-
ate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates 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 GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.

Warm up engine thoroughly to make sure there is no leakage of fuel, 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.
