b. Hold the top of the oil pump shaft using the socket (size: E8),

and then loosen the oil pump sprocket nut and remove it.

c. Remove the crankshaft sprocket (1), the oil pump drive chain

(2), and the oil pump sprocket (3) at the same time.

INSTALLATION

NOTE:

For installation follow the relationship between the matching mark on

each timing chain and that of the corresponding sprocket, with the

components installed.

1. Install the crankshaft sprocket and the oil pump drive related parts:
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 toward the back of the engine.

• Install the oil pump sprocket so that its protrusion faces 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 using the socket (size: E8),

and then tighten the oil pump sprocket nut.

c.

Install oil pump drive chain tensioner (1).

• Insert the body into the shaft (B) while inserting the spring into

the attaching 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:

• 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:

• After the matching marks are aligned, keep them aligned

by holding them. 

• To avoid skipped teeth, do not rotate crankshaft and cam-

shaft until front cover is installed.

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

guide (1).

(1) : Crankshaft sprocket
(2) : Oil pump drive chain 
(3) : Oil pump sprocket

4. Install chain tensioner (1).

• Secure the plunger at the most compressed position using a

stopper pin (A), and then install it.

• Pull out the stopper pin after installing the chain tensioner.

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-71, "FRONT OIL SEAL : Removal and Installation"

.

7. Install front cover with the following procedure:
a. Apply a continuous bead of liquid gasket to the front cover as

shown. 

Use Genuine Silicone RTV Sealant or equivalent. Refer to
