Turn oil pump shaft so that the drive pin (31) engages
in the groove of the camshaft.
◆
NOTE:
Models from the year 1995 onwards have a suction
inner and outer rotor of height 16 mm (0.63 in.) instead
of 13 mm (0.51 in.).
◆
NOTE:
Apply LOCTITE 515 to the crankcase in the area of the
crack between the two crankcase halves.
Push both needle pins (23) 4x15.8 into the pump housing, insert O-ring
(25) 57-3 and tighten oil pump cover (22) crosswise by hand evenly with
allen screws (12) M6x50 and lock washers. After this tighten allen
screws (12) crosswise. Tightening torque 10 Nm (90 in.lb).
Fit ball 8.5 mm (0.33 in.) (21), pressure spring (20) 39.5 mm (1.55 in.)
and screw plug (18) M12x1 and secure with wire. Tightening torque with
oiled thread 15 Nm (133 in.lb).
