Removing the components of the output side
The output side has different shapes depending on the product type:
- Smooth shaft
- Shaft with shaft key
- Splined shaft (DIN 5480)
- Blind hollow shaft / hollow shaft / hollow shaft interface / flange hollow shaft
- Flange
- With mounted output pinion
For details on how to remove the components of

There are customer-specific designs for all other types of outputs. The removal of these outputs
cannot be described here.
