Ducati Diavel Service Manual: Refitting the oil pump

If removed, apply specific threadlocker on the bushing (7) outer thread, and screw it in the crankcase half, observing the height.

Position the reference bushings (15) and the oil sealing o-rings (2) and (4) according to the crankcase lubrication channels.

Position the oil pump on the crankcase and tighten screws (9) to a torque of 26 nm (min. 23 Nm - max. 29 Nm) and the screw (10) to a torque of 10 nm (min. 9 Nm - max. 11 Nm) (sect. 3 - 3, Engine torque settings).

Check the gear clearance with the driving pinion by fixing a dial gauge (a), equipped with the appropriate traces, to the crankcase half.

Position the dial gauge stylus on one tooth of oil pump gear and set the gauge to zero in this position.

Move the gear slightly to measure the backlash; take four readings in diametrically opposed positions of the gear.

The clearance should be 0.10 Mm.
