Calculating max. permissible reworking dimension
Calculating max. permissible reworking dimension
–  Insert valve and press firmly against the valve seat.
  Note
If the valve is replaced when carrying out repair work, use a new valve for the measurement.
   
–  Measure distance -a- between the end of the valve stem and the upper face of the cylinder head.
–  Calculate max. permissible reworking dimension from the distance -a- measured and the minimum dimension.
Minimum dimension:
t  Inlet valve: 43.4 mm
t  Exhaust valve: 43.2 mm
Measured distance less minimum dimension = max. permissible reworking dimension.
Example:
  S15-0303

-		Measured distance

=max. permissible reworking dimension0,7mm

  Note
If the max. permissible reworking dimension is 0 mm, repeat measurement with a new valve. If the max. permissible reworking dimension is again 0 mm, replace cylinder head.
