Procedure for the replacement of grease:
•
Inspect tightness and replace the sealing elements, if necessary.
•
Turn the coupling until the screw plugs are in vertical position (see illustration 31).
•
Remove the screw plugs (component 7) along with the sealing washers (component 6) and afterwards drain
the grease into a suitable tank. To facilitate the replacement you may add thin oil.
Please check the compatibility of the oil with the grease!
•
Perform grease feeding as per chapter 5.4.
•
Repeat this process with the other coupling half.

!
In case of leakages (escape of grease) defective sealing elements have to be replaced
immediately!
The coupling may be damaged if these hints are disregarded.
The grease escaped has to be fully collected and disposed of according to the regulations
that apply.
Replacement of flat gasket (component 5):
If the flat gasket (component 5) is defective/untight, it has to be replaced immediately. Furthermore we would
recommend with each reassembly of the coupling to replace the flat gasket (component 5) and the dowel screws
(component 3) as well as nuts (component 4).
•
Drain the grease as per chapter 7.2.
•
Unscrew and remove the screwing (components 3 and 4) of the sleeves (component 2).
•
Shift the sleeve (component 2) axially backwards until the flat gasket (component 5) can be disassembled and
replaced.
•
Lightly grease the sealing surfaces and insert new flat gasket (component 5). Afterwards inspect the alignment
and, if necessary, re-align and assemble.
•
Perform grease feeding as per chapter 5.4.
