power steering pump on 2000 Ford Ranger

With pump installed, how do I keep shaft from turning to allow me to install pulley? I do have a puller/installer tool but when I begin shaft just turns and backs bolt out of shaft? Whats the trick??

The tool should thread easily in to the threads in the shaft. Sounds like the threads could be different or has a burr. can put pulley on shaft and push down to hold and thread in but make sure are correct threads. When threaded in the installer should have a "pusher" that has a bearing in between the pusher and the front of the pulley. Hold the end of the threaded installer with a wrench and turn the pusher with another till bottoms out, remove and make sure pulley is tight on shaft and spins.
