the figure.

Use Genuine RTV silicone Sealant or equivalent. Refer to

GI-15, "Recommended Chemical Products and Sealants"

.

c.

Assemble front timing chain case.

CAUTION:

• Be careful not to damage front oil seal by interference

with front end of crankshaft.

• Attaching should be done within 5 minutes after liquid

gasket application.

d.

Install front timing chain case as to fit its dowel pin hole together dowel pin on rear timing chain case.

e.

Tighten mounting bolts to the specified torque in numerical order
as shown in the figure.
• There are two types of mounting bolts. Refer to the following

for locating bolts.

f.

After all bolts are tightened, retighten them to the specified
torque in numerical order shown in the figure.

CAUTION:

Be sure to wipe off any excessive liquid gasket leaking on surface mating with oil pan (upper).

g.

Install two mounting bolts in front of oil pan (upper) in numerical
order shown in the figure. 

11. Install valve timing control covers (bank 1 and bank 2) as follows:

TIMING CHAIN

a.

Install new seal rings (1) in shaft grooves.

CAUTION:

When replacing seal ring, replace all rings with new one.

b.

To check the joint between dowel pins and dowel pin holes,
check the looseness in the axle direction by pushing the circum-
ferential looseness (between dowel pins and dowel pin holes) by
twisting in the circumferential direction.

CAUTION:

Always perform this procedure when removing because the
gap between dowel pins and dowel pin holes may not be
caused on purpose.

c.

Install valve timing control cover with new gasket to front timing
chain case.

CAUTION:

• Never face the magnet retarder side down to prevent mag-

net retarder from dropping.

• Check the mating surface of magnet retarder and the

drum of exhaust side camshaft sprocket for foreign mate-
rials.

• Align the center of both shaft holes of the shaft and the

intake side camshaft sprocket, and then insert them.

• Be careful not to drop the seal ring from the shaft groove.
• When setting the valve timing control cover in position by hand, if valve timing control cover is

not contacting with the front timing chain case, the dowel pin of magnet retarder may not be
aligned with the dowel pin holes of cover. In this case, return to step “b”.

d.

Being careful not to move seal ring from the installation groove, align dowel pins on front timing chain
case with holes to install valve timing control covers.

e.

Tighten mounting bolts in numerical order as shown in the fig-
ure.

• After all bolts are tightened, tighten No. 1 bolt to the specified

torque again.

12. Install oil pan (lower). Refer to 

EM-43, "Exploded View (2WD)"

 (2WD models) or 

EM-44, "Exploded View

(AWD)"

 (AWD models).

13. Install rocker covers (bank 1 and bank 2). Refer to 

EM-47, "Exploded View"

.

14. Install crankshaft pulley as follows:

a.

Fix crankshaft using the ring gear stopper [SST: KV10118600 (J-48641)].

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.

Place a matching mark (A) on crankshaft pulley (2) aligning with
the matching mark (C) of crankshaft pulley bolt (1). Tighten the
bolt 90 degrees (one marks) (b).

e.

Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.

15. For the following operations, perform steps in the reverse order of removal.

Inspection

INFOID:0000000003139118

INSPECTION AFTER REMOVAL

Timing Chain

Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage.

• 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-10, "Fluids and Lubricants"

.

• 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 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.

TIMING CHAIN

• Warm up engine thoroughly to check 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.

Summary of the inspection items:

* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
