Oil pump

See pag. 25 if you wish to check the rotors.
Fit the external oil pump rotor with the bevel toward the inside of the
cover (fig.70).
Torque the bolts to:

pump priming when the engine is started up for the first
time.

are aligned (fig.69).
Fit the oil seal onto the cover using a normal tubular punch of appro-
priate diameter. Mount the cover to the crankcase (fig.71) after first
inserting a gasket between the mating surfaces; tighten the screws
to:
kgm 2,2 ÷ 2,4 (Nm 21,6 ÷ 23,8)
