Make sure that the cylinder segment
D
of the de-
compressor is not worn or chipped.
Should it be deteriorated, replace the decompres-
sor shaft. In order to extract it, remove the Benzing
ring
4
and pull the shaft out. Operate inversely to
reassemble it. If replacing the decompressor shaft,
replace the Benzing ring as well.
3.17.7 CHECKING CAMSHAFTS SUP-
PORT
The camshafts supports fasten the shafts so they
maintain the correct position while operating. The
support in the zone
A
has a channel
B
intended
to lubricate the camshaft to allow the hydrodyna-
mic support of the shaft itself. Therefore you must
make sure that the zones
A
are free from scratches
or traces of corrosion.
Make sure the zones
C
for housing the roller bea-
rings have no traces of meshing or scratches.
Attention:
If the support needs to be replaced, the
cylinder head must be replaced as well.
