The diagram gives the diameters: the outside diameter of the
cylinder liner and the inside diameter of its seat.
If necessary, the cylinder liners can be extracted and fitted
several times in different seats.
Replacing Cylinder Liners
!
The crankcase can be levelled off only after making
sure that, after machining, the piston protrudes from
the cylinder liner from 0.19 to 0.59 mm.
If the measurements are higher than as shown in the figure, it
is necessary to change the cylinder liners. Their internal surface
is treated with liquid nitriding, so grinding, lapping or facing are
not permissible.
-
Check the flatness of the cylinder head mating surface with
a calibrated rule and feeler gauge.
After finding the areas of deformation, level off the
supporting surface, after taking out the centring pins (2),
with tool (1), and the cylinder liners (3) according to the
procedures given under the heading REPLACING
CYLINDER LINERS.
-
Remove the cylinder liners (2) from the cylinder assembly
with tool 99360799 (1) fitted as illustrated in the figure.
Carefully check the seats of the cylinder liners and the side
surfaces of the crankcase.
Check the state of the plugs fitted in the cylinder assembly
machining holes and replace them if they are rusty or there
is any doubt about their seal
