TIMING CHAIN

4.

Hold the WAF part of oil pump (2) shaft [WAF: 10 mm (0.39 in)]
(A), and then tighten the oil pump shaft sprocket bolt.

CAUTION:

• Secure the oil pump shaft with the WAF part.
• Never loosen the oil pump shaft sprocket bolt by tighten-

ing the oil pump drive chain.

5.

Install oil pump chain tensioner (1).
• Fix the plunger at the most compressed position using a stop-

per pin (A), and then install it.

• Securely pull out (

) the stopper pin after installing the oil

pump chain tensioner.

• Check matching mark position of oil pump drive chain and

each sprockets again.

6.

Align the matching marks of each sprockets with the matching
marks of timing chain.

*: There are 2 outer grooves in camshaft sprocket (INT). The wider one is a
matching mark.

• If these matching marks are not aligned, rotate the camshaft

slightly by holding the hexagonal portion to correct the posi-
tion.

CAUTION:

Check matching mark position of each sprocket and timing
chain again after installing the timing chain.

7.

Install the slack guide (2) and the tension guide (3).

8.

Install timing chain tensioner (1).
• Fix the plunger at the most compressed position using a stop-

per pin (A), and then install it.

• Securely pull out the stopper pin after installing the timing

chain tensioner.

TIMING CHAIN

9.

Check matching mark position of timing chain and each sprockets again.

10. Install front oil seal. Refer to 

EM-63, "FRONT OIL SEAL : Removal and Installation"

.

11. Install front cover with the following procedure:

a.

Install new O-ring to cylinder block. 

CAUTION:

Never misalign O-ring.

b.

Apply a continuous bead of liquid gasket (B) with a tube presser
(commercial service tool) to front cover as shown in the figure. 

Use Genuine RTV Silicon Sealant or equivalent. Refer to 

GI-

22, "Recommended Chemical Products and Sealants"

.

c.

Check that matching marks of timing chain and each sprockets are still aligned. Then install front cover.

CAUTION:

• Check O-ring on cylinder block is correctly installed.
• Be careful not to damage front oil seal by interference with front end of crankshaft.

d.

Install front cover, and tighten mounting bolts in the order of 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 crankshaft pulley with the following procedure:

g.

Put a paint mark (B) on crankshaft pulley (2), matching with any
one of six easy to recognize angle marks (A) on crankshaft pul-
ley bolt (1) flange. 

h.

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

i.

Check that crankshaft rotates clockwise smoothly.

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

INSPECTION AFTER REMOVAL

Timing Chain

Check for cracks (A) and any excessive wear (B) 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-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.
