Vacuum Pump & Pulley Problem

I recently bought my PSD with 318,000 on the clock, and I've been working through fixing some things that the PO messed-up. A week ago, my serpentine belt went out while traveling on the highway, so I replaced with a new one from NAPA, and made sure to triple-check the diagram under the hood to route the belt properly. About 20 miles later, I notice a clanging noise from under the hood. Since I was about 0.5 mile away from my house, I drove home and parked the truck, and this is what I find under the hood. The pulley to the vacuum pump is almost totally off the pump!

From what the previous owner told me, he recently replaced the vacuum pump. My question is: how is the pulley attached to the vacuum pump? Is it install using a press? I've included some it possible that whoever replaced the vacuum pump just simply did not press the pulley on hard enough? This seems odd to me.

The pulley is installed and removed using a "power steering pump pulley" installer/remover like this one: OEM/Pulley puller installer kit (27031) | Power Steering Pulley Puller/Installer |

The PO may not have installed correctly (they usually won't come off). Cheers!

Do not use a press to install the pulley. You will damage the guts in the pump. Like Feeley said, only use a PS shaft press tool.
