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.

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.

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.

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.
