Inspection of cylinder head
The flatness tolerance for the cylinder head is max. 0.12
mm (.00472"). Check in six positions ("A-F" as per Fig.
15
and 16). Use a feeler gauge and a ruler the sides of
which are precision rubbed as per DIN 874/Normal.

Remove residual soot and impurities from the cylin-
der head�s sealing surfaces.
Note: Do not use use steel brush to clean the cylin-
der head screw threads or under the screw heads.
If the flatness is not within the permissible tolerance the
cylinder head should be replaced. If leakage or blow
marks are confirmed it is not necessary to check for flat-
ness since the cylinder head must be replaced.
Check the valve seats and that the pin screws are tight.
For replacement of the valve seats (inlet) see next
