Power steering pump pulley help

[Bruno]

Can anyone tell me how this pulley comes off? It’s seems like it should slide off the shaft and it is loose back and forth but I’m assuming there’s a key holding it in place. Here’s a pic with the nut removed.

Another option...
I had a small local auto shop pull the pulley off and put the rebuild kit in for $25. This is the kind of shop that rebuilds the AC clutch or starter solenoid rather than replace the whole assembly. I would have rented the kit but I try to throw some small jobs to the local shops when I can to try and build a relationship for future odd jobs that are out of my experience or tool capability.
