Remove the screw plug (19) from the hub (3).  

 

Connect the pump (

p

max

= 3000 bar

) to the thread G¼ or G¾ (c) of hub (3) 

to expand the hub.  

 

Screw the pump to the shaft (A), in order to hold the hub.  

 

Build up oil pressure in order to hold the hub.  

  

 WARNING 

 

 Material damage can occur as a result of: 

 

Too fast increase of the expanding pressure in the hub 

The increase of the expanding pressure may not exceed 

35 bar/minute

. 

  

 

Slowly build up oil pressure to expand the hub (

p

max

= 1500 bar

). 

 

Slowly reduce the oil pressure for holding the hub. 

 

Slowly reduce the oil pressure for expanding the hub. 

 

Repeat the above mounting section until the hub is completely released from 
the shaft. 

 

Remove the pump for holding the hub from the shaft (A). 

 

Remove pump for expanding the hub from the hub (3). 

 

Turn the hub (3), drain oil out of the thread G¼ or G¾ (c) and dispose 
correctly. 

 

Screw the screw plug (19) into the hub (6). 

 

Remove the hub (3) from the shaft (A). 

  

9.5.3

 

Dismantling the CENTA-conical clamping hub 

See Fig. 6-4: 

 

Loosen the screws (22) and screw them out equally about 10mm. 

 

For each forcing thread (g) screw out a screw (22) and screw them loose into 
the forcing thread (g). 

 

Force away the ring (2) by screws (22) of the forcing threads. 

 

Remove the screw (22). 

 

Remove the ring (2) with hub (3) off the shaft (A). 

  

9.6

 

Reassembling the coupling 

 

Reassemble the coupling as described in chapter 6.
