3.11.1 ASSEMBLY OF LOW PRESSURE
PUMP
Insert the internal rotor 1 on the shaft 2 so that the
dot on the face of the rotor faces inwards. Then in-
sert the roller 3 on the shaft.
Use motor oil to lubricate the seat of the rotors on
the outside of the crankcase half, insert the external
rotor 4 and the internal shaft-rotor unit in its proper
seat.
Insert the ball 5 (diameter 5.5mm) and the respec-
tive compression spring 6.
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 7 to the crankcase with the three
screws 8, which must first be spread with medium
strength threadlocker. These screws must be tighte-
ned at a torque of 6Nm.
