Crankcase

Disassembly

Remove the oil filter and the heat exchanger with rela-
tive bearing.
Remove as follows as indicated in the relative para-
graphs:

A) The head
B) The cylinder group
C) The pistons
D) The clutch
E) The gear

Remove:
F) The size 6 screws including the one for the blow-by

cap.

Remember to unscrew the screw inside
the carter indicated in the picture at the
right.

G) The size 8 screws.

All the screws are of the same length or
visually different; it is therefore impossi-
ble to confuse them during reassembly.
