Dismantling a Kenwood Prospero KM260/MX260

[Embroiderr]

Hi,

 

Has any body experienced dismantling the Kenwood Prospero KM260 (MX260).  I am following the service manual however I cannot seem to get the medium speed drive coupling or the high speed drive coupling undone -  the manual says 'Turn in a clockwise direction to remove'.   This I have tried but neither part will come undone. -  Is there a trick to it i.e. push/raise and turn perhaps?

 

 

 

Update,

 

In the end I didn't have to take the high speed coupling off as this part has been superseded by another part.  Repair by replacement.
