Valve Clearance Adjustment Table of Exhaust Valve
Thickness (mm)
1. Measure the valve clearance (the engine has been cooled).
2. Check the current valve shim dimension.
3. The valve clearance in the vertical column corresponds to the current valve shim dimension in the horizontal column.
4. The value in the space crossed by the vertical column and horizontal column refers to the specified valve shim
dimension. When the valve shim dimension is equal to the value in the space, the valve clearance value is just
appropriate.
For example: the thickness of current valve shim is 1.60 mm.
The measured valve clearance is 0.33 mm.
Replace the shim of 1.60 mm with the valve shim of 1.70 mm.
5. Measure the valve clearance again and carry out adjustment again if necessary.
