Villier C12 & Alcon pump - strip down question

Afternoon all

Have acquired al Villiers C12/Alcon pump set complete. I am in the process of stripping the engine set down but am unsure of how the pump is seperated from the drive off the engine.

Can anyone point me in the direction of how to remove the pump?
I have attached a photo to help.

Thanks

David

I'm not 100% sure but I think the engine may have an extended crankshaft with the impeller on the end, in other words you have to remove the impeller to remove the pump casing from the engine.

Thanks i did think this however the impeller has been secured to the shaft in a way that is not removable. So wanted to check first.
