Apply the two O-rings to the cylinder. Rest the
head so that water hose is facing the front of
the engine. Grease the screws and apply them

2. 27Nm
Fastening of head.
15Nm
27Nm
The gaskets are supplied in four different thick-
nesses:
∙ 0,3mm;
∙
0,4mm;
∙
0,5mm
that can also be stacked, thus obtaining the nec-
essary height for the right thickness.

ried out once all four crankcase cylinder cou -
pling nuts have been fastened at the set torque

Measure play with thickness gauge and increase
gasket thickness so contact between plate and
cylinder is guaranteed, if the piston pushes the
plate upwards failing contact between plate and
cylinder. Carry out the check again.
