Question - Water Pump Removal - OM617

On the OM617, can the water pump be removed from the housing, with the housing left on the engine?

It look like it can be removed by itself after the five 10mm head bolts are out, but it hasn't freed up after reasonable effort using PB Blaster on the gasket area.

The Haynes manual says that the pump comes off with the housing. This sounds like there is additional attachment of the pump on the back of the housing, in the water jacket..... is this the case?

Thanks for any information.
