IMPORTANT:
Risk of damage!
Due to the technical requirements, the special tool used, sleeve G,* is relatively thin-walled. To ensure that the load limit of the tensioning sleeve is not exceeded when drawing in the output shaft, it is essential to use adapter 81 64 2 318 661 in combination with a torque wrench.

Fit adapter with torque wrench to hydraulic unit (see graphic).
Set torque wrench to 20 Nm .
Draw in output shaft with hydraulic tool until the torque wrench is activated.
