FRONT TIMING CHAIN CASE
4. Apply Silicone RTV Sealant to front timing chain case as shown.
• Use Genuine Silicone RTV Sealant, or equivalent. Refer to
21, "Recommended Chemical Products and Sealants"
.
• Before installation, wipe off the protruding sealant.
• C: 2.6 - 3.6 mm (0.102 - 0.142 in) dia.
CAUTION:
• Installation should be done within 5 minutes after apply-
ing liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after
the components are installed to allow the sealant to cure.
5. Install dowel pin on the front timing chain case into dowel pin hole in rear timing chain case.
6. Loosely install the front timing chain case bolts.
7. Tighten the front timing chain case bolts in the order as shown.
• Retighten the front timing chain case bolts in the order as
shown.
8. Install upper oil pan bolts (1) and (2) as shown. Refer to
"Removal and Installation (Upper Oil Pan)"
.
9. Install lower oil pan. Refer to
EM-36, "Removal and Installation (Lower Oil Pan)"
.
10. Install intake valve timing control solenoid valve covers.

a. Install new seal rings (1) in shaft grooves.
CAUTION:
• When replacing seal rings, replace all rings with new ones
on both intake valve timing control solenoid valve covers.
• Do not reuse O-rings.
b. Check the joint between dowel pins and dowel pin holes for
excessive free play.
• (A): Mating surface of magnet retarder
• (B): Moves slightly
• (C): Not shaken
CAUTION:
Always perform this procedure when removing to ensure
the dowel pin holes are not worn or elongated.
c. Being careful not to move seal ring from the installation groove, align the dowel pins on the front timing
chain case with the holes to install valve timing control covers.
d. Install intake valve timing control solenoid valve cover with a
new gasket to front timing chain case.
CAUTION:
• Do not face magnet retarder side down to prevent magnet
retarder from dropping.
• Check the mating surface of the magnet retarder and the
drum of the exhaust camshaft sprocket for foreign materi-
als.
• Align center of both shaft holes of the shaft and the intake
camshaft sprocket, and then insert them.
• Be careful not to drop the seal ring from the shaft groove.
• When setting the intake valve timing control solenoid valve cover in position by hand, if intake
valve timing control solenoid valve cover is not centered with the front timing chain case, the
dowel pin of the magnet retarder may not be aligned with the dowel pin holes of the intake valve
timing control solenoid valve cover. In this case, return to step "b".

e. Tighten intake valve timing control solenoid valve cover bolts in
the numerical order as shown.
11. Apply liquid gasket and install the water pump cover, if removed.
• Use Genuine Silicone RTV Sealant or equivalent. Refer to
GI-21, "Recommended Chemical Products
CAUTION:
• Installation should be done within 5 minutes after applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the components are installed to allow
the sealant to cure.
12. Install crankshaft pulley and tighten the bolt in two steps.
• Lubricate thread and seat surface of the bolt with new engine oil.
• For the second step angle tighten using Tool.
13. Remove the Tool to unlock the driveplate.
CAUTION:
Do not damage the ring gear teeth, or the signal plate teeth behind the ring gear, when removing
the Tool.
14. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
15. Installation of the remaining components is in reverse order of removal.
INSPECTION AFTER INSTALLATION
• 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-15, "FOR USA AND CANADA : Fluids and Lubricants"
(United
States and Canada) or
MA-16, "FOR MEXICO : Fluids and Lubricants"
(Mexico).
• 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, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and 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 fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
