3.11.2) Reworking of the sealing surface to the exhaust manifold
See Fig. 72-63.
Reworking is permissible if there is a leak at the sealing surface (1) to
the exhaust manifold.
The diameter of the sealing surface must not be increased to more than
dimension CH09. See 72-00-00 sec. 4.
The material removed during reworking must be compensated for by
assembling a copper sealing ring (2), part no. 931920. The sealing ring
is available as a spare part.
■ CAUTION: Ensure that the reworked sealing surface is free of
tool chatter marks.
Reworking must be carried out with a suitable countersink until the
sealing surface is clean.
■ CAUTION: It must be ensured that the lock nut can be screwed
onto the stud far enough to allow the lock nut to
function correctly.
