Ducati Diavel Service Manual: 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.
The following is a list of possible causes of clutch malfunctions.
A clutch which does not disengage may be caused by:
- Excessive play of the control lever;
- Distorted clutch plates;
- Incorrect spring tension;
- Faulty clutch release mechanism;
- Excessive wear of the hub or clutch drum.
A clutch which slips may be caused by:
- Insufficient play of the control lever;
- Insufficient play of the control lever;
- Weakened springs;
- Faulty clutch release mechanism;
- Excessive wear of the hub or clutch drum.
A noisy clutch may be caused by:
- Excessive backlash between the primary drive gears;
- Damaged primary drive gear teeth;
- Excessive play between friction plate tabs and the clutch drum;
- Worn gear/clutch drum bearings;
- The presence of metal particles (filings) on the gear teeth.

Injection relay
Introduction
The fuel pump, injectors and ignition coils are all powered via the injection
relay. The relay also sends voltage to the
engine control unit, which enables activation of the relay itself.

Accelerator position sensor (throttle grip)
Introduction
An accelerator position sensor (aps) is mounted on the throttle body of the
diavel, which measures the degree of aperture
of the throttle grip.
The throttle grip is connected to the sensor via two metal cables
The sensor transmits information to the ecu relative to the "torque ...
