Refinishing
Note
Refinish prechamber sealing surface when
damaged or leaking. The first refinishing
operation on the prechamber sealing surface can
be performed with the cylinder head removed or
installed. If the sealing surfaces have already
been refinished once before, this can be
recognized by the markings (punch marks) in the
area of the prechamber mounting bores or on
the spacers installed. In this case
it is necessary to remove the cylinder head
to refinish again. The prechamber projection
dimension " C" (7.6 - 8.1 mm) can only be
measured precisely with the cylinder head
removed. Maintenance of this projection
dimension ensures that the necessary distance
between the prechamber and piston crown is
present when the piston is in the TDC position.
