mm (2.40 in).

5. Remove the front cover.
a. Loosen and remove the bolts in the reverse of order shown.
b. Cut the liquid gasket and remove the covers using Tool.

CAUTION:

Do not damage mating surfaces.

6. Remove the front oil seal using suitable tool.

CAUTION:

Do not damage front cover.

7. Remove the oil pump drive spacer.
8. Remove the oil pump assembly.

INSTALLATION

1. Install the oil pump. 
2. Install the oil pump drive spacer as follows:

• When inserting the oil pump drive spacer, align the crankshaft

key and the flat face of the inner rotor.

• If they are not aligned, rotate the oil pump inner rotor by hand.

• Make sure that each part is aligned and tap lightly until it

reaches the end.

3. Install the front oil seal using suitable tool.

CAUTION:

Do not scratch or make burrs on the circumference of the

oil seal.

4. Install the front cover as follows:
a. Install a new O-ring on the cylinder block.

b. Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

c.

Check again that the timing alignment marks on the timing chain

and on each sprocket are aligned. Then install the front cover.

d. Install the bolts in the numerical order shown.

e. After tightening, re-tighten to the specified torque.

CAUTION:

Be sure to wipe off any excessive liquid gasket leaking onto

surface mating with oil pan.

5. Install the Intake valve control solenoid valve cover (RH) (A) and

Intake valve control solenoid valve cover (LH) (B) as follows:

a. Apply liquid gasket (D) as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

GI-14, "Recommended Chemical Products and Sealants"

.

CAUTION:

The start and end of the application of the liquid gasket

should be crossed at a position (C) that cannot be seen

after attaching the Intake valve control solenoid valve

cover.

b. Install the bolts and tighten them to specification in the numeri-

cal order shown.

• A: Intake valve control solenoid valve cover (RH)

• B: Intake valve control solenoid valve cover (LH)

6. Install the crankshaft pulley.

• Install the key of the crankshaft.

• Insert the pulley by lightly tapping it.

CAUTION:

Do not tap pulley on the side surface where the belt is installed (outer circumference).

7. Tighten the crankshaft pulley bolt.

• Lock the crankshaft using suitable tool, then tighten the bolt. 

• Perform the following steps for angular tightening:

a. Apply engine oil onto the threaded parts of the bolt and seating area.
b. Select the one most visible notch of the four on the bolt flange.

Corresponding to the selected notch, put a alignment mark

(such as paint) on the crankshaft pulley. 

8. Rotate the crankshaft pulley in normal direction (clockwise when viewed from engine front) to check for

parts interference.

9. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

1. Check the engine oil level. Refer to 

LU-24, "Inspection"

2. Start the engine and check for engine oil leaks.
3. Stop the engine and wait 10 minutes.
4. Check the engine oil level and adjust the engine oil level as required. Refer to 

LU-24, "Inspection"

DISASSEMBLY

1. Remove oil pump cover.
2. Remove inner rotor and outer rotor from oil pump body. 
3. Remove the regulator valve plug, regulator valve spring and regulator valve.

INSPECTION AFTER DISASSEMBLY 

Clearance of Oil Pump Parts

• Measure radial clearance using a suitable tool.

• Measure side clearance using suitable tools.

• Calculate the clearance between inner rotor and oil pump body as

follows.

1. Measure the outer diameter of protruded portion of inner rotor

(position 5) using suitable tool.

Body to outer rotor (position 1)
: 0.114 - 0.200 mm (0.0045 - 0.0079 in)

Inner rotor to outer rotor tip (position 2)
: Below 0.180 mm (0.0071 in)

Body to inner rotor (position 3)
: 0.030 - 0.070 mm (0.0012 - 0.0028 in)

2. Measure the inner diameter of oil pump body to brazed portion

(position 6) using suitable tool.

3. Calculate the clearance using the following formula.

• (Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor)

Regulator Valve Clearance

Check regulator valve to oil pump cover clearance using the following formula.

• (Clearance) = D

1

 (Valve hole diameter) - D

2

 (Outer Diameter of

valve)

CAUTION:

• Coat regulator valve with engine oil.

• Check that it falls smoothly into the regulator valve hole by its

own weight.

ASSEMBLY

Installation is in the reverse order of removal.

NOTE:

Install the oil pump inner rotor and outer rotor with the punched

marks on the oil pump cover side.
