Ducati Diavel Service Manual: Description of the clutch assembly

Ducati Diavel Service Manual / Engine / Clutch assembly / Clutch / Description of the clutch assembly

The clutch is disengaged by a drive unit consisting of a thrust piston (c) accommodated inside a small cap mounted to the generator cover. This piston (c) pushes a pushrod (b), which runs through gearbox primary shaft and operates the Pressure plate (4) located on top of the clutch plate pack (9).

Drive is transmitted from the crankshaft to the gearbox primary shaft by a gear integrated with the clutch housing/primary drive gear pair (a).

Accommodated in the clutch housing is a set of drive and driven plates (9). When the clutch is operated, the driven plates push away a drum (12) which is splined onto the gearbox primary shaft.

Before working on the internal clutch parts, check that the clutch operates correctly. Then deal with the problem in a systematic manner.
