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.
