Measured distance minus minimum dimension =
max. permissible reworking dimension.
Example (for outer intake valve):
Measured distance 31.4 mm
- Minimum dimension -31.0 mm
= max. permissible
reworking dim. = 0.4 mm
Note:
If the maximum permissible reworking dimension
is 0 mm or less than 0 mm, repeat the
measurement with a new valve. If the measured
result is again 0 mm or less than 0 mm, replace
the cylinder head.
