Spring washers
The spring washers provide the braking
force to the clutch when the nut is fitted
and tightened with the correct torque.
To function properly it is vital that
the washers are installed correctly and
that they are intact.
Remove the spring washers
Lift up the three spring washers and flat
washer under them.
Remove the friction washer
Remove the friction washer from the
gear wheel. Replace the washer if it is
damaged or has significantly reduced

drive wheel in a vice with soft fibre jaws.
Start by screwing in the nut to the
mechanical stop position. Now unscrew
+
the nut 45°. The clutch must have a
slipping torque of at least 16 Nm. If the
value is not reached, the spring and
friction washers must be replaced.
If the slip clutch is higher than 16 Nm,
adjust the value to the correct level.
