Extraction of Benzing ring from decompressor shaft.
Make sure that the cylinder segment
D
of
the decompressor is not worn or chipped.
Should it be deteriorated, replace the de-
compressor shaft. In order to extract it, re-
move 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.
CHECKING CAMSHAFTS
SUPPORT
The camshafts supports fasten the shafts
so they maintain the correct position whi-
le operating. The support in the zone
A
has a channel
B
intended to lubricate the
camshaft to allow the hydrodynamic sup-
port 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 rol-
ler bearings have no traces of meshing or
scratches.
Attention:
If the support needs to be repla-
ced, the cylinder head must be replaced as
well.
