3.8.4 Clutch disc check
The clutch discs are divided into driving and driv-
en: seven driving discs and six driven discs of
which four in aluminium and two in steel.
The driving discs have cork inserts on both sides
which wear out due to the driven discs sliding on
them.
Make sure that the thickness between the two
inserts positioned on the opposite faces of each
driving disc is not below the minimum value fixed
at:
minimum distance between two opposite in-
serts: 2.8mm
The other measurement that needs to be checked
is the thickness of the teeth of each driving disc,
which must not be less than the minimum set at:
minimum driving disc tooth thickness: 13.3mm
Check the state of use of the silent-blocks as fol-
lows. Clamp gear B using protective elements and
impose a rotation to the clutch case. If there is
play between the case and the gear unit, replace
the clutch case.
Check the state of use of the internal centre bear-
ing 1 which must have no traces of meshing or
abnormal wear.
Check the condition of the roller bearing 2 . If
worn, it must be replaced.
