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, "Component".
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 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 figure.
 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.
 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.

e. Tighten mounting bolts in numerical order as shown in the fig-
ure.
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 hamme r, 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 (clock wise 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 incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-44, "
Recommended Chemical Product and Sealant".
 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 leak-
age at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
 Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops af ter 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 applic able lines, such as in cooling system.

TIMING CHAIN
Do not overtighten slack guide
mounting bolts. It is normal
for a gap to exist under the bo lt seats when mounting bolts
are tightened to the 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 rachet 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, theplunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diamet er thin screwdriver being used as the stopper pin.
e. Install timing chain tensioner (primary).  Remove any dirt and foreign materials completely from theback and the mounting surfaces of timing chain tensioner (pri-
mary).
