4) INSERT the shift shaft with the lower washers (0.6 mm thick) (1- F.44) and insert the return spring hooks in the
relevant anchoring bridge (F.45) then check that:
- By putting the desmodronic shaft in 3
rd
speed, make sure the rollers of the cam are at an equal distance
from the fork hooks. On the contrary, slightly bend the ends of the spring until obtaining the requested
condition.
5) FIT the countershaft in the clutch crankcase.
N.B.: assembly of the countershaft in its seat implies no interference.
6) If it has been removed, FIT the connecting rod in the crankcase on flywheel side using the tool (1 - F.46);
keep the connecting rod at the T.D.C. whilst tightening the screw, until the connecting rod touches the
bearings.
7) FIT the dowel bolts (1-2 - F.47), apply gasket paste on the mating sides of the crankcases (F.47) and oil all
shafts. Place the crankcase (flywheel side) over the other crankcase and tap gently all over with a wooden,
leather or plastic mallet until the crankcases are joined.
8) FIT the 13 fixing screws and tighten in place (Cs 1.0 ÷ 1.2 kg*m). Make sure all shafts can turn freely. Make
sure that none of the shafts feature excessive end play, in which case, separate the crankcases and replace
the top shim washer with another having a more suitable thickness.
9) FIT the new oil seals, using the specific plug for each.
