Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.

Recover the spacer (8), the Belleville washer (35) and the cable guide (9).

In some models you might find a different type of retaining screws for cover (36), as follows: there are two screws (42) retaining cover (36) to generator cover that are on top of the special screws (40) and (41) that fix the generator cover.

Fix service tool no. 88713.1749 to the holes left vacant by the two bolts (6) you have just removed.

Undo the three stator retaining screws (24) and the two screws (31) securing the cable guide bracket (30) from inside the gen­erator cover.

Use service tool no. 88713.3367.

Unscrew the alternator/flywheel nut (34), heating it with a hot air gun; do not use a naked flame as this could damage the starting system components.

While unscrewing the nut, apply axial pressure to the socket to avoid damage or injury in the event of the wrench suddenly slip­ping off the nut.

Insert two of the screws (25) just removed from flywheel rotor-side in their holes in order to remove the flange (13) and the starter clutch (21).

Seat the flange (13) with the starter clutch in the flywheel (16), aligning the flange locating hole (B) with the flywheel locating hole (C).

When refitting the flange to flywheel, insert a pin or a wrench inside the hole (C) for the rotor flywheel locating dowel (14) in order to line up the flywheel holes with flange threads. This is a useful tip, as the holes cannot be aligned after having fitted the flange to the flywheel due to the interference fit.

Tighten the screws (25) to the specified torque (Sect. C 3, Engine torque settings).

Fit the washer (17), duly lubricated, the needle roller bearing (19), and the inner ring (18) to the crankshaft.
Make sure the inner ring is centred on the washer.

Fit the previously assembled flywheel-rotor-driven gear on the crankshaft, taking care not to alter the position of inner ring (18) with respect to the washer (17).

Restrain the rotation of the flywheel with the holding tool 88713.3367.

Tighten the nut (34) to the specified torque (Sect. C 3, Engine torque settings).

Smear the stator screws (24) with recommended threadlocker and tighten to the specified torque (Sect. C 3, Engine torque set­tings).

Before refitting, make sure that the crankshaft end bearing (26) and relative retaining ring (27) are installed on the generator cover (28).

Spread a continuous uniform bead of DUCATI liquid gasket on the mating surface of the cover (28), ensuring continuity around the holes for the retaining screws and locating bushes.

Install under the screw (12), in correspondence with the starter motor, the spacer (8), the guide (9), the washer (35) and install the cover (36) under screw (11) in correspondence with the alternator lead: for instructions on the positioning of the wiring under the cover (36) see below.

Tighten the fixing screws to the specified torque (Sect. C 3, Engine torque settings).

In some models you might find a different type of retaining screws for cover (36), as follows: there are two screws (42) retaining cover (36) to generator cover that are on top of the special screws (40) and (41) that fix the generator cover.

Fasten the generator cover tightening the special screws (40) and (41) (M6x30 mm) to the specified tightening torque (Sect. C 3, Engine torque settings) then fasten cover (36) to generator cover tightening the screws (42) to the specified torque (Sect. C 3, Frame torque settings).

Offer the cover (36) up to the generator cover and position the fuel tank breather hose (T) and the airbox drain hose (U), the side stand cable (R), generator cable (S) and the starter motor cable (Q) as shown.

Damp the sealing ring (3) with alcohol and install it in the generator cover, in correspondence with the gearchange shaft (Sect. F 5, Refitting the gearchange mechanism) by means of the suitable drift.

Tighten the two fixing screws (6) of the cover (5) matching the crankshaft to the specified torque (Sect. C 3, Engine torque set­tings).
