504 91 06-05
Unscrew the clutch –
clockwise
The clutch has a left-hand thread.
It is marked with the dismant-
ling direction "Off".
Warning!
Never use impact on the puller – this will damage the piston. Even dis-
mantling without the piston stop using a striking tool results in a risk of
damage to the flywheel's locking mechanism (keyway/key).
Wear tolerances
Engagement speed – min. 3100 rpm
The clutch must be rectified if the blade starts to rotate at an engine speed
below 3100 rpm.
≤ 3.14 in.
Clutch shoes
≤ 79.8 mm
The height of the clutch shoe's bevelled section should not be less than .04 in.
/1 mm. Replace if necessary for the complete clutch. Never replace individual
shoes from another clutch – this creates imbalance.
