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.
Set torque wrench to 20 Nm.
Draw in output shaft with hydraulic tool until the torque wrench is activated.
Tighten collar nut (1), activate parking brake for this purpose.
Installation note:
Renew collar nut (1), apply a light coating of oil to collar nut contact surface and tighten.
No oil permitted on thread of shaft journal or collar nut.
