Valve Clearance Inspection
VALVE CLEARANCE INSPECTION1. 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 it is not within the specification, replace the tappet and adjust the valve clearance to the standard clearance.
Standard valve clearance [when cold]
IN: 0.22-0.28 mm (0.0087-0.0110 in)
EX: 0.27-0.33 mm (0.0106-0.0130 in)
Note
- When replacing the tappet, select the tappet according to the measured value and note down the measured value.
3. Rotate the crankshaft clockwise 360° so that the No.4 piston is at the TDC of the compression stroke.
4. Measure the valve clearance at B in the figure.
- If it is not within the specification, replace the tappet and adjust the valve clearance to the standard clearance.
Standard valve clearance [when cold]
