TESTING THE CLUTCH DISCS
The clutch discs are divided into driving and
driven elements: six driving discs and five
driven discs.
Both sides of the driving discs have cork in-
serts that become worn due to the sliding
movement with the driven discs.
You must verify that the thickness between
two inserts placed on opposite sides of each
driving disc is not less than the minimum
value set at: minimum distance between
two opposite inserts: 2.5 mm.
Another value you must verify is the tooth
thickness of each driving disc and this must
not be less than the minimum value set at:
minimum tooth thickness of the driving
discs: 13.5 mm.
Moreover, verify the distortion of the driven
discs. This is implemented by resting the
driven discs onto a perfectly flat surface and
with the use of a feeler blade verify that the
gap between the disc and surface does not
exceed: acceptable distortion of the dri-
ven discs: 0.10 mm.
