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). ...
Other materials:
Removal of the starter motor idler gear
Slide the gear pin (21) complete with the gear (19) and washer (20).
Warning
Pay attention to the washer (20) since it may fall inside the
crankcase half.
At this point, it is possible to remove the starter motor as described in
sect. 6 - 3, Starter motor. ...
Removal of the oil pump
Undo and remove the screws (9) and (10) securing the pump assembly.
Remove the oil pump assembly (1) and extract the o-rings (2) and (4) from the
crankcase half together with two locating
bushes (15).

Operating principle and characteristics of the ride-by-wire system
The engine control system of the diavel uses a ride-by-wire system with
motorised throttle valves. This eliminates all
direct connection with metal cables between the throttle grip and the throttle
valves themselves. Cables are used to
rotate the aps potentiometer, which generates an electric ...
