Hold the top of the oil pump shaft, and then loosen the oil pump
sprocket nuts and remove them.

c.

Remove the crankshaft sprocket (1), the oil pump drive chain
(2), and the oil pump sprocket (3) at the same time.

INSTALLATION

NOTE:
The figure shows the relationship between the matching mark on
each timing chain and that on the corresponding sprocket, with the
components installed.

TIMING CHAIN

a.

Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.

• Install the crankshaft sprocket so that its invalid gear area (A)

is towards the back of the engine.

• Install the oil pump sprocket so that its hexagonal surface

faces (B) the front of engine.

NOTE:
There is no matching mark in the oil pump drive related parts. 

b.

Hold the top of the oil pump shaft, and then tighten the oil pump
sprocket nuts.

c.

Install chain tensioner (1).
• Insert the body into the shaft (B) while inserting the spring into

the fixing hole (A) of cylinder block front surface.

• Check that the tension is applied to the oil pump drive chain

after installing.

2.

Install timing chain with the following procedure.

• Install by aligning matching marks on each sprocket and tim-

ing chain.

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

slightly to correct the position.

CAUTION:

• For the following note, after the matching marks are aligned, keep them aligned by holding them

with a hand. 

• To avoid skipped teeth, never rotate crankshaft and camshaft until front cover is installed.

3.

Install timing chain tension guide (2) and timing chain slack
guide (1).

4.

Install 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 chain ten-

sioner.

5.

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

6.

Install the front oil seal to the front cover. Refer to 

EM-87, "FRONT OIL SEAL : Removal and Installation"

7.

Install front cover seal. Refer to 

EM-58, "Exploded View"

.

CAUTION:

Be careful not to damage front cover.

8.

Install front cover with the following procedure:

a.

Clean front cover mounting surface and engine surface in contact with front cover.
• Surface must be proper without any liquid gasket, water or dust.

b.

Apply a continuous bead of liquid gasket with tube presser
(commercial service tool) to front cover as shown in the figure. 
Use Genuine Liquid Gasket or equivalent.

CAUTION:

Applying excess of liquid gasket can create damage on
parts during tightening sequence.

TIMING CHAIN

c.

Apply a continuous bead of liquid gasket with tube presser
(commercial service tool) to front cover as shown in the figure. 
Use Genuine Liquid Gasket or equivalent.

NOTE:
Liquid gasket must be applied at a distance of 1.0mm (0.04 in)
to 2.0mm (0.08 in) from the inside edge of the timing cover.

CAUTION:

Applying excess of liquid gasket can create damage on
parts during tightening sequence.

d.

Tighten bolts in the numerical order as shown in the figure fol-
lowing the procedure.
1.

Tighten mounting bolts No. 14, 7,10 and 12.

2.

Tighten mounting bolts No. 1, 2, 3, 4, 5, 6,. 

3.
