My Braun Multimix Blender MX32 needs repairing?

I am trying to replace the grey drive toothed coupling that engages the cutting blades for the bowl. It seems like it is fairly easy to replace as the new one should just press in. However it is old and I just cannot take it off. If anyone knows hoe to remove it, I would be very greatful as I am doing this for a friend.
Thanks

I asked the agent of Braun of Hong Kong, about the gasket for mx32..... yes..they got it, just cost me HK$20.00 each.
Why not you try too?

Are you sure you don't just need a new thermal fuse (Microtemp 117C)?
