K - Use a knife-edge straightedge and feeler
gauge to measure distortion of cylinder head
at several points.
Max. permissible distortion: 0.1 mm
(Minimum distance over which straightedge
is resting: 100 mm)
- If the distortion is greater than 0.1 mm, re-
work or replace cylinder head.
K - It is only permissible to rework the sealing
surface of cylinder head (surface grinding)
to the minimum dimension -a-.
♦ Minimum dimension -a-: 132.6 mm
Note:
If the sealing surface is reworked, the valves
must be set lower by the same amount (rework
valve seat rings) otherwise the valves will strike
the pistons. When doing this, ensure that the
permissible maximum dimension is not ex-
ceeded ⇒ page 15-22.
