3.1.4) Oil pump assembly (on 912 Series)
See Fig. 79-5
Lubricate bearing bore for pump shaft in oil pump housing with engine
oil and install pump shaft (30). Push needle pin (26) 4x15.8 into the
pump shaft (30), insert suction inner and outer rotor (24) and turn the
pump shaft to check it. Fit the 2 outer O-rings (4) 11-2.7 and O-ring (5)
30-2.5 in the oil pump housing and fit it to the crankcase.
â—† NOTE: Turn oil pump shaft so that the drive pin (31) engages
in the groove of the camshaft.
â—† 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.).
â—† 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 (23) evenly with allen
screws (12) M6x50 and lock washers.
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 to
25 Nm (18.5 ft.lb).
â—† NOTE: The adjusting shim (19) is not supplied as standard
equipment. It is only fitted if a test run reveals that the
oil pressure is too low.
If the oil filter nipple (15) has been removed, re-tighten it to 60 Nm (44.3
ft.lb). Slightly lubricate the rubber seal for oil filter (11) with engine oil.
Screw oil filter on by hand until it touches the oil filter housing. Then
tighten by an extra 3/4 turn. Nipple (1) (connecting nipple, metric 14x1.5
or screw socket UNF), oil pressure sensor (17), oil temperature sensor
(16) and screw plug (32) must be fitted LOCTITE 243.
â—† NOTE: On configuration 3, the pressure oil line for the gover-
nor is connected instead of the screw plug. Tightening
torque of banjo bolt (6) 17 Nm (150 in.lb).
