repairing limit value: 1.5mm

If the valve seat is to wide or narrow or cracked,grind

it to ensure impermeability.

4、Measure bore diameter of valve guide with internal micrometer

and special gauge.At last calculate clearance between valve

stem and valve guide.

Repairing limit value: intake : 0.12mm exhaust: 0.14mm

Note :Eliminate carbon in the pipe before

measuring.If the pipe will be replaced,grind the

valve seat again .

5、Inspection of valve and valve pipe:

Check whether the valve is bent,burn or the valve stem is

worn out.

Check the motion of valve and measure external diameter.

Repairing limit value: intake : 5.95mm exhaust: 5.95mm

See figure 2-21.

Fix valve into guide,and look over the motion.
