Application of the complete piston band on cylinder.
Insertion of piston in cylinder.
Application of pin bolt to piston.
Press the piston downwards having the
higher segment of the skirt protrude a bit
from the band. Rest the unit on the cylinder,
making sure that the contact zones of the
band rest correctly on the cylinder surface.
For this purpose, make sure that the upper
edge
C
of the band is perfectly aligned with
the contact surface of the cylinder.
Note:
When positioning the complete band-
piston unit on the cylinder, be careful to place
them so that the arrow stamped on the crown of
the piston faces the exhaust manifold.
Holding the band firm with one hand, push
the piston inside the cylinder, making sure
that the axis of the piston is aligned with
that of the cylinder. Towards the end of in-
sertion it might be necessary to use the wo-
oden handle of a hammer or a similar tool
to lightly tap the piston crown in order to
facilitate its complete insertion in the cylin-
der.
Attenzione:
Attention: during the whole opera-
tion, hold the band firm with one hand without
moving it. Make sure that the piston rings insert
themselves correctly in the cylinder when pas-
sing through the band. Should there be excessi-
ve resistance when inserting the piston into the
cylinder, do not insist in order not to deteriorate
the parts. Find out the cause.
When the piston has been inserted into the
cylinder and the band has been removed,
press the piston towards the bottom of the
cylinder so that the pin bolt seats come out
from the lower edge. Apply the pin bolt
1
into the right-hand seat as much as needed
to allow it to be coupled with the connec-
ting rod.
