 CAUTION 

 

Material damage to coupling components can occur as a result 
of: 

 

Anaerobic adhesives (e.g. Loctite) used for screw locking 

This type of screw locking medium may not be in contact with rubber 
parts. 

  

 

IMPORTANT 

 

Screw preparation and tightening torque levels in accordance with  
CENTA data sheet D013-013 (see chapter 11.1). 

 

Use suitable lifting devices for assembly.  

 

The following assembly stages are described for coupling 033N-00064-F.00.  

 

Part illustration and marking may different slightly from installation drawing and 
delivery state.
