is it dhw diaphragm, the one that faces you that always leaks from the pin. are you just fitting dia service kit?

if so isolate cold supply to boiler underneath and open hot tap to drain, then crack on undoing the 6 , 7 screws and impulse tube.
keep pressure on as you undo cos its quite a tensioned spring.
