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
Reassembling the clutchRemoval of the tail light
Disconnect the connectors (a) and (b) of the tail lights (1) and (13).
Loosen the screws (4) and slide the tail lights (1) and (13) to the rear side;
recover the four spacers (3) and the washers
(14).

Reassembly of the oil pump
Check that the circlip (3) and tongue (13) are present on the pump.
Fit the pump drive gear (12) on to the oil pump and secure it by installing the
circlip (6) in its groove.
Insert the by-pass valve pump (17), the spring (16) and screw the plug (14).
Tighten the plug (14) to a torque of ...
Reassembly of the cylinder head
The exhaust side can be identified by the three threaded holes on the flange.
The intake side can be identified by the presence of four threaded holes on
the flange.
All the photos in this chapter refer to a vertical cylinder head.
Valve guide sealing rings
Position the cylinder head o ...
