Measuring steel disc distortion.
Clutch spring length measurement.
Checking inner hub teeth.

A
Also check the distortion of the steel discs. This
operation is done by placing the steel discs on
a perfectly flat surface and using a thickness
gauge to check that the clearance between the
disc and the surface is not greater than:
allowable distortion
steel discs: 0.10mm
3.12.3 CHECKING SPRINGS
To ensure the correct pressure between the
clutch discs, the state of the springs must
be checked. The minimum acceptable length
must be:
minimum clutch spring length:
42 mm
3.12.4 CHECKING INNER HUB
The inner hub meshes with the steel clutch di-
scs by means of the teeth A: Make sure these
teeth are not meshed or shaped by abnormal
wear. If so, replace the inner hub.
Make sure that the seat B where the support
washer of the disc spring slides shows no tra-
ces of meshing. If so, replace the drum.
Also control that the radial holes present on
the inner hub are not obstructed and are free
from sediments.
