Use motor oil to lubricate the seat of the rotors on
the outside of the crankcase half, insert the external
rotor

and the internal shaft-rotor unit in its proper
seat.
Insert the ball

(diameter 5.5mm) and the respec-
tive compression spring

Lubricate with motor oil and, while rotating the pro-
truding segment of the drive shaft (from the outside
of the right crankcase half), make sure it rotates
freely and does not jam.
Fasten the cover

to the crankcase with the three
screws
