Install front cover, and tighten mounting bolts in the order from 1
to 22 as shown in the figure.
• Refer to the following for the installation position of bolts.

CAUTION:

Attaching should be done within 5 minutes after liquid gas-
ket application.

e.

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

CAUTION:

Be sure to wipe off any excessive liquid gasket leaking.

12. Install VTC cover according to the following instructions:

a.

a.Apply liquid gasket 

 (Three Bond 1217H or an equivalent)

evenly (no break, no overlap) to the position shown in the figure.
Refer to 

EM-9, "Liquid Gasket"

.

CAUTION:

Install within 5 minutes after applying liquid gasket.
NOTE:
Overlap the start and end of liquid gasket application positions
at least 5 mm.

b.

Install O-ring to the groove of front cover 

.

CAUTION:

Oil filter must be inserted to the end of O-ring installation
part.

c.

Tighten mounting bolts to the specified torque in the order from
1 to 8 as shown in the figure.

CAUTION:

After tightening mounting bolts, wipe out extra liquid gas-
ket.
NOTE:
Bolt 1 must be tightened twice, the second tightening is shown
by 6.

13. Install crankshaft pulley with the following procedure: 

a.

When inserting crankshaft pulley with a plastic hammer, tap on its center portion (not circumference).

CAUTION:

Never damage front oil seal lip portion.

b.

Secure crankshaft pulley 

 with a pulley holder (commercial

service tool) 

.

c.

Apply new engine oil to thread and seat surfaces of crankshaft
pulley bolt.

d.

Tighten crankshaft pulley bolt.

e.

Put a paint mark 

 on crankshaft pulley 

, matching with any

one of six easy to recognize angle marks 

 on crankshaft pulley

bolt  

flange. 

f.

Turn another 60 degrees clockwise (angle tightening).
• Check the tightening angle with movement of one angle mark.

g.

Check that crankshaft rotates clockwise smoothly.

14. Install remaining parts in the reverse order of removal.

Check for cracks

 at link plates and

roller links of timing chain. Replace timing chain if necessary.

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases 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-23, "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.

• 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:

*: Power steering fluid, brake fluid, etc.
