Place a clean cloth between the piston and
the crankcase to keep foreign objects or sim-
ple residue from falling inside the base. Using
a suitable tool to insert the specific seat A,

From the left hand side of the piston, push the
pin bolt with an aluminium cylinder B (or the
likes), until the pin bolt is freed from the foot
of the connecting rod.
Remove the piston.

hand first of all. If it is too tight, hit the pin
lightly with a rubber hammer, at the same
time holding the piston with your hand in or-
der not to stress the connecting rod.
