Dismantling the CENTA-conical clamping hub/flange hub  
See Fig. 6-5: 

¾

 

Loosen the screws (2.4/6.4) and screw them out equally about 10mm.  

¾

 

For each forcing thread screw out a screw (2.4/6.4) and screw them loose 

into the forcing thread (l).  

¾

 

Push the hub/flange hub (2.1/6.1) off hub-taper (2.2/6.2) with the help of 
the screws (2.4/6.4) in forcing threads.  

¾

 

Remove the screws (2.4/6.4).  

¾

 

Remove the hub-taper (2.2/6.2) with hub/flange hub (2.1/6.1) off the shaft 

(A).

Dismantling the hub/flange hub with conical oil interference fit 

 WARNING 

 

Injury and material damage can occur as a result of: 

ƒ

 

Non-compliance with the operating instructions for the hydraulic 

pumps 

Before carrying out work with the hydraulic pumps, do not fail to read 
their operating instructions. Only ever work with hydraulic pumps as 

described in their operating instructions. 

  

 WARNING 

 

Injury and material damage can occur as a result of: 

ƒ

 

Hydraulic fluid spraying out  

Use protective goggles. 

  

 WARNING 

 

 Injuries and material damages can occur by: 

ƒ

 

Suddenly loosening hubs 

Secure the hub with a hydraulic tool against sudden axial loosening. 

  

 

IMPORTANT 

We recommend the following mounting fluids: 

 

 

For mounting: 

Oil with a viscosity 300 mm

2

/s at 20°C, e.g. SKF LHMF300 

 

For dismantling: 

Oil with a viscosity 900 mm

2

/s at 20°C, e.g. SKF LHDF900
