17) FIT the springs and fixing screws and tighten (Cs 0.3 ÷ 0.5 kg*m).
18) Correct operating position of the clutch is obtained when the lever, in the position indicated by the arrow
(F.55), is parallel to the cover resting surface.
To obtain this condition, turn the adjustment screw (1-F.56) on the last disc, using the special wrench
(2- F.56). Tighten the nut (Cs 2.6 ÷ 2.8 kg*m) .
19) BEFORE fitting the starter assembly (version without an electric starter), make sure that the phase between
the pawl on the sliding rod and the hole for fixing the spring is the same as before disassembly (90° - F.57).
20) FIT the starter assembly, whilst hooking the spring to the hub on the cover.
21) FIT: the dowel bolts and a new gasket on the crankcase; the clutch cover; if necessary, this operation can be
made easier by turning the impeller of the water pump. Secure in place with screws (Cs 1.0 ÷ 1.2 kg*m).
If you have disassembled it, refit the oil pump, making sure that the O-ring is in working order (1 - F.58a).
When refitting, take care not to damage the oil pump gear.
Whilst fitting the starter lever on its shaft, turn it 180° counter-clockwise and secure in place with the fixing
screws (Cs 2.9 ÷ 3.0 kg*m) (F.58b).
This operation must be performed to pre-load the return spring.
