20) DISASSEMBLING
the thermal section:
a) unscrew the 4 cylinder head holding nuts and remove the relevant washers; remove the
head, its O-ring, the cylinder, the cylinder gasket and the four O-ring on the stud bolts.
CAUTION: before removing the circlips of the piston pin, put a clean cloth
into the opening on the crankcase, to prevent the circlips dropping into the
engine.
21) REMOVE
the two circlips (F-18), remove the piston pin and, if you intend to use a 2-
diameter plug, knock gently taking care to hold the piston on the opposite side in order to
avoid damaging the connecting rod.
22) REMOVE
the 13 screws joining the two crankcases (F-19) and take the clutch pin out
of its seat.
23) SEPARATE
the 2 crankcases by gentling tapping the secondary shaft and shift shaft
with a wooden mallet.
IMPORTANT: if you need to take the crankshaft out of its seat, use the spe-
cial tool (1/F-20).
24)
Once the crankcases have been separated,
CHECK
that the shim washers are on the
shafts and not on the crankcase that has just been removed (F-21).
