7. Remove the ventilation hose.
8. Remove the cylinder head cover.
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 inches)
EX: 0.27 - 0.33 mm (0.0107 - 0.0129 inches)
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.
