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.

Refitting the lubrication system
Note
Before fitting the pipes (7), it is recommended to check the presence of
the o-rings (e). Lubricate them by using engine
oil.
If the nipples (5) have been removed from the radiator insert a washer (6) on
each nipple (5) and apply specific
threadlocker on threads on the radiator side ...
Removal of the clutch transmission unit
Warning
The manufacturer of the clutch transmission unit (15) advises
against servicing of its internal parts due to the safetycritical
nature of this component.
Incorrect overhaul of these critical safety components can endanger rider and
passenger safety.
The only components that shoul ...
