- Measure the free length of
the mobile driven half-pulley
spring.
Standard length: 125.5
mm
Admissible limit after
use: 120 mm
- Check the thickness of the
clutch mass friction material.
Minimum admissible
thickness: 1 mm
- The masses must exhibit no
traces of lubricants; in that
case, check the driven pulley
unit seals.
N.B.: Upon running-in, the masses must exhibit a central contact surface
and must not be different from one another. Different conditions may
cause the clutch tearing.
- Do not open the masses using tools to prevent a variation in the return spring load.
