water pump innards

Have to get the water pump to run if the demo is to be a working engine, so I figured would take a closer look at the possibility of making it run off a 12 volt motor.The core metal of the pressed on pulley either needs to be removed with a special puller, or I need to machine a new plastic pulley. Will have to ponder that one, I don't want to brake it trying to pull off the rusted pulley.
Pump has thermostat and additional oil loop. Nice that it is all o ring seals.
