TIMING CHAIN

a.

Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to front timing chain case back side as
shown in the figure.

Use Genuine Liquid Gasket or equivalent.

b.

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

c.

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

locating bolts.

d.

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

CAUTION:

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

e.

After installing front timing chain case, check the surface height
difference between the following parts on the oil pan (upper)
mounting surface.

• If not within the standard, repeat the installation procedure.

13. Install intake valve timing control covers as follows:

a.

Install new seal rings in shaft grooves.

b.

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

c.

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

14. Install crankshaft pulley as follows:

a.

Install crankshaft pulley, taking care not to damage front oil seal.
• When press-fitting crankshaft pulley with a plastic hammer, tap on its center portion (not circumference).

b.

Fix crankshaft with the pulley holder (commercial service tool).

c.

Tighten crankshaft pulley bolt.

d.

Place a paint mark (A) on crankshaft pulley (1) aligning with the
angle mark (B) on crankshaft pulley bolt (2). Tighten the bolt 90
degrees (angle tightening).

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

smoothly.

16. Install in the reverse order of removal after this step.

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 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 

MA-11, "Fluids and Lubricants"

TIMING CHAIN

• 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.

• 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.
