marker should face the piston top.

10. Apply the engine oil to the

connecting rod bearings and
install the connecting rod journal
and the bearing cap.

11. Install the connecting rod to the

crankshaft. Inspect whether the
bearing clearance is acceptable.
Refer to 2.6.1.2 "Mechanical
System Specification".

Standard Value

2.6.8.21 Valve Clearance Adjustment

1. Dismantle the plastic shield of engine. Refer to 2.6.8.1 Replacement of Plastic Shield of

Engine.

2. Refer to 2.10.7.3 "Replacement of Ignition Coil" to dismantle the ignition coil.

3. Refer to 2.6.8.2 "Replacement of Cylinder Hood Cover" to dismantle the cylinder hood

cover.

4. Refer to 2.6.8.9 "Replacement of

Timing Chain Shroud" to
dismantle the timing chain
shroud and rotate the crankshaft
making cylinder No.1 at
compression TDC position.

5. Inspect valve clearance. Use the

plug gage to measure valve
clearance value, as arrows shown
in the graphic and record the
valve location and tolerance that
exceeds the tolerance.

Valve clearance standard value
(Cold):

Air intake

0.25±0.03mm

Exhaust: 0.3±0.03mm

FE02-3060b

6. Rotate the crankshaft one circle

(360 °), making the cylinder No.
4 stop at the compression TDC
position. Measure the valve
clearance as arrow pointed in the
graph and record the clearance.

7. Use a jack to support the engine.

Dismantle the timing chain.
Refer to 2.6.8.10 "Replacement
of Timing Chain"

8. Refer to 2.6.8.12 “Replacement

of Camshaft” to dismantle the
camshaft.

9. Remove the valve lifter that

exceeds the tolerances. Use
outside diameter micrometer to
measure the thickness, according
to the following formula
calculate the thickness of the new
valve lifters.

FE02-0289b

Intake: A=B+C-0.23 mm(0.01in)

Exhaust: A=B+C-0.32mm(0.13in)

10. Selected new valve lifters must be as close as possible to the calculated values. For

specifications. Refer to 2.6.1.3 Specification Table for Tappet Rods of Intake and Exhaust
Valves for the thickness of the tappet rod of valve.

11. Based on the measurement, according to 2.6.1.4 Selection Table for Tappet Rod of Exhaust

Valve, choose the tappet rod of valve to meet the specification.

12. Install intake and exhaust camshafts.

13. Install timing chain

14. Install the timing chain cover.

15. Install the ignition coil.

16. Install the plastic shield of engine.
