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 expansion tank
Loosen the clamp (6), open the hose guide (a) and slide the hose (7) out of
the radiator.
Open clamps (14) and release the hoses that pass through them.
Loosen the screws (16).
Remove the tank (12) with its hoses (7) and (20) and the support (15).
Loosen the clamp (19) to r ...

Recharging the battery
Examine the label on the battery showing the check intervals in order to
determine when to test the voltage.
Charge the battery if the open circuit voltage is lower than 12.8 V. Leaving
the battery discharged for more than one
month could damage it. Check the battery charge with a voltmete ...
