Procedure
The gear unit can be equipped with alignment threads in the housing feet to make it simpler
to align.
Figure5-2:Alignment surface
Proceed as follows to align the gear unit at the alignment surface:
1. For the precise position of the alignment surfaces, refer to the dimension drawings in the
complete documentation.
2. Note the values inscribed in the alignment surfaces.
3. Using these alignment surfaces, horizontally align the gear unit so that perfect gear unit
operation is ensured.
The diagram below shows the alignment surfaces and alignment threads on gear units of
type K..H:

Tools
The following tools are needed to perform the final fine alignment (Page71) work on the
shaft axes of the gear unit and the equipment installed on the input and output sides.
• Rulers
• Spirit level
• Dial gauge
• Laser alignment system
• Feeler gauge etc.
Once the gear unit is finely aligned, tighten the foundation bolts and check the settings
again. Record the alignment dimensions and keep the report in a safe place together with
these operating instructions.
