centring of clutches

When the driving disk is replaced, it must be centred in the balance wheel at all costs.

Demonstration:

• Unscrew the pressure plate without centering (plug-in type connection). In mounting the transmission, the transmission input shaft can not be pushed into the guide bearing
• Centering of the driving disk with a centering mandrel (red)
• The transmission input shaft can now easily be pushed into the guide bearing
