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:
Refitting the front sprocket
Grease the o-ring (16) and install it on the front sprocket spacer (15).
Fit the spacer, from the o-ring side, on the secondary shaft and drive it fully
home against the inner ring of the bearing.
Check that the splines of the gearbox secondary shaft and the sprocket are in
perfect condi ...
Refitting the front brake system
While refitting the system, pay special attention to the orientation of the
pipe couplings (24) on the pump and the pipes
(13) and (20) on the callipers (9) and (18).
Warning
If incorrectly positioned, the hose can affect brake operation and
foul moving parts. Position the hose as shown in th ...
Reassembly of the gearbox
To refit the gearbox components follow the procedure under sect. 9 - 9.2,
Reassembly of the crankcase halves, relating to
reassembly of the engine crankcase.
As a final practical test, ensure that with the gearbox in neutral the front
coupling dogs (a) of sliding gears (b) are
equidistant o ...
