VALVE CLEARANCE INSPECTION [L3]

1. Disconnect the negative battery cable.
2. Remove the tire (RH).
3. Remove the splash shield (RH).
4. Remove the plug hole plate.
5. Remove the spark plugs.
6. Remove the oil control valve (OCV) connector.
7. Remove the ventilation hose.
8. Remove the cylinder head cover.
9. Verify that the engine is in cold condition.
10. Measure the valve clearance.
(1) Turn the crankshaft clockwise so that the No.1 piston is at TDC of the compression stroke.





(2) Measure the valve clearance at A in the figure.
^ If the valve clearance is out of the standard value, adjust it.

Note:
^ Make sure to note down the measured values for choosing the suitable replacement tappets.

Standard [Engine cold]
IN: 0.22-0.28 mm (0.0087-0.0110 in)
EX: 0.27-0.33 mm (0.0107-0.0129 in)

(3) Rotate the crankshaft 360° clockwise so that the No.4 piston is at TDC of the compression stroke.
(4) Measure the valve clearance at B in the figure.
^ If the valve clearance is out of the standard value, adjust it.

Note:
^ Make sure to note down the measured values for choosing the suitable replacement tappets.
