Before mounting, check the flexibility of the valve spring
using tool 99305047. Compare the loading and
deformation data with those of the new spring indicated
in the following diagrams.
REPLACING THE INJECTOR—HOLDER
CASES
Imperfect coupling between the injector and case, forced into
the cylinder head or between the case and the seat on the
cylinder head, causes a loss of compression or water leakage.
In the first case, the trouble is eliminated by regrinding the seat
of the case (2) with the milling cutter 99394011 (3) and the
bushing 99394019 (1) taking account that the electro—injector
recessing from the cylinder head face must be from 0.47 to
1.16 mm.
In the second case, it is necessary to replace the case as follows:
-
thread the case with the set of screw taps 99390800 (1);
-
extract the case from the cylinder head with tool
99342145 (2).
