10) FIT the key for the magneto flywheel; put the stator in its seat and fasten in place with the fixing screws (Cs
0.25 ÷ 0.3 kg*m). Fit the rotor and tighten the nut (Cs 4.3 ÷ 4.5 kg*m), using the usual wrench (F48).
11) Fit the sprocket: snap ring (1-F49) - sprocket (2) - snap ring (1) - fit the clutch control pin (3- F49) with its return
spring (4-F49).
12) CHECK operation of the sprocket and gear wheel pair.
If any of the gears needs to be replaced, it is recommended to replace the pair since this will ensure smoother
and quieter operation.
13) FIT the crankshaft (clutch side) in the following order:
1) The overturned oil seal (1 - F.50), using the special plug (2 - F.50)
2) The O-ring (1 - F.51)
3) The spacer (2 - F.51), with the bevelled side facing the crankshaft. Push in place until it stops.
Now fit the key (1 - F.52), the countershaft drive gear (2 - F.52), the drive sprocket and the nut (Cs 6.7 ÷ 7.5
kg*m). Fit the key and driven gear on the countershaft (2-F.53), making sure that the reference notches on the
two gears match (F.53). Tighten the nut (Cs 4.5 ÷ 5.0 kg*m) (apply Loctite 242).
