The following work steps describe pressing out the output shaft:
The following tools are required to press out the output shaft from the drive flange, see graphic for arrangement:
Vehicle components:
| I | Drive flange hub |
| II | Wheel bearing/swivel bearing |
Necessary components:
| 1 | Hydraulic unit |
| E3 | Washer M24 |
| F3 | Spindle M24 (length 270 mm) |
| C1 | Holding sleeve |
| K2 | Screws M14 x 1.5 |

- Secure output shaft against falling out
- Press out output shaft with hydraulic unit
The following work steps describe drawing in the output shaft:
The following tools are required to fit the output shaft in the drive flange, see graphic for arrangement:
Vehicle components:
| I | Drive flange hub |
| II | Wheel carrier/swivel bearing |
| III | Output shaft |
Required components for all models and types:
| 1 | Hydraulic unit |
| E1 | Holding sleeve M24 |
| D1 | Washer |
| F2 | Spindle M24/M20 (length 335 mm) |
Components specific to model and type (thread diameter, output shaft):
| G3 | Adapter M27 x 1.5 to M20 |
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.
