Ducati Diavel Service Manual: Checking and overhauling the components
Clearance between the clutch drum and friction plates
Insert a friction plate (e) in the clutch drum (f) and measure the clearance (s) with a feeler gauge.
Clearance "s" must not exceed 0.6 Mm.
If it does, renew the plates and, if necessary, the clutch drum.
Overhaul of the clutch plates
The clutch plates must not show any signs of blackening, grooves or deformation.
Measure the thickness of the friction plates; it should not be less than 2.6 Mm.
Important
The total thickness of the discs pack must not be less than 46.1 Mm.
Place the plate on a flat surface and check the amount of deformation with a feeler gauge.
Max. Flatness error: 0.2 Mm.
Overhaul of the pressure plate
Check bearing (5) condition; renew the bearing if the play is excessive.
Check the contact surfaces of the last friction plate; if extremely scored, polish it in the same manner as described previously for the cylinder head surface (sect. 9 - 4.5, Overhaul of cylinder head components).
Check conditions of the spring guide bucket tappet (g) of the pressure plate (4) and of the circlips (6).
Overhauling the pressure plate springs
Measure the length "l" of each spring (3).
Minimum length: 41 mm.
Renew any springs that are shorter than the above limit value.
Removal of the clutch
Note
For clarity, the figures show the engine removed from the frame.
Undo the fixing screws (1) and remove the ring (2) and the springs (3) from
the pressure plate (4).
Slide the pre ...
Reassembling the clutch
Position the spacer (13).
Fit the flat ring (11) and the belleville washer (10) on the clutch center
(12), so that the convex side faces the clutch
drum.
Locate the belleville washer (8). ...

Cylinder compression test
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
Engine performance is directly correlated to the pressure that can be
measured in the combustion chambers of the two
cylinders. Pressure which is too high/low or an excessive difference be ...
Total distance covered indicator: "odometer"
This function shows the total distance covered by the vehicle (in km or miles
depending on the specific application).
At key-on the system automatically enters this function.
The odometer reading is stored permanently and cannot be reset.
If the distance travelled exceeds 199999 km (or 19 ...
Air temperature sensor
Introduction
The engine control system on the diavel uses a sensor that measures air
temperature. This sensor has a resistance of
ntc type (negative temperature coefficient), that reduces its own value when the
temperature increases. The air
temperature sensor allows the engine control unit t ...
