- Temporarily install the
cylinder on the piston without
base gasket.
- Install a comparator on the
specific tool using the short
union, as shown in the figure.
Specific equipment and
tools:
Piston position check
support 020475Y
- Using an abutment plane,
reset the comparator with a
pre-load of a few millimetres.
- Finally fix the comparator.
- Check the perfect sliding of
the feeler pin.
- Install the tool on the cylinder
without changing the
comparator position.
- Lock the tool by the original
head fastening nuts.
- Turn the driving shaft to the
TDC (point of reversal of the
comparator rotation).
- Measure the deviation from
the reset value.
- Identify the thickness of the cylinder base gasket to be used for re-assembly by the table
below. The proper identification of the cylinder base gasket thickness allows maintaining the
correct compression ratio.
- Remove the specific tool and the cylinder.
N.B.:
If deviations (or recesses or projections) close to the change of category are
measured, repeat the measurement at the opposed side. To do so, repeat the tool
installation by inverting its position.
