Power steering pump pulley - press fit?

[Mobile Mike]

I need to replace my power steering pump soon, bearing is grinding. I have not removed it yet to examine. Is the pulley pressed onto the shaft, or is it keyed with a set screw? I have found
good deals on replacement pumps without the pulley, wondering what I might be getting myself into.
Mine is part #16792A39, goes on my 2012 5.0 EFI.

Thanks

Pressed...You can probably borrow what you need to install /remove at an Auto Zone.
