Water Pump/pulley Failure

Has anyone had the water pump/pulley come loose or wobble?

My pulley developed a wobble which caused it to fail. I thought it was just me but I ran into another person with a supercharger that had the exact same issue.
When I went to order a replacement water pump I noticed that the one that came factory was no longer available and was replaced with a new style using 4 bolts to connect the pulley.

Wondering if anyone else has encountered this issue or if it is a known problem.

Yep, my pulley car loose about a month after installing my Procharger. I know I torqued the three bolts to spec with a torque wrench. Luckily I heard the rattle and tightened them back down a little over spec this time. It's only been about 1000 miles since then, but they appear to be holding on this time around. As an FYI, my crank bolt was loose as well, glad I caught that for sure.

Did it sound like this? I'm thinking about diving into the pulley system this weekend.

Never checked mine , but after this post I'm going to !!

Sorry I can't really make it out. I noticed mine about a mile from my house, there was a rattle I could hear while driving it, loud enough to know something wasn't right when driving. I pulled over an shut it off and the water pump pulley bolts were less than finger tight. The sound went away after I finger tightened them with a rag (was so wishing I had a wrench in my car). Got home and tightened them down. Figured it might be a good time to check others bolts I could get to, and the crank bolt was just a smudge loose, probably less than half a rotation (at least that's what I'm telling myself now). Also some of the cam bolts on the PC pulley were not quite as tight as I left them.
Worst part is, it had been on my mind to go through and recheck the torques again, but just never the right time. Hope yours is just as simple to fix.

ps. I guess I should knock on wood.

You did let the motor and crank bolt cool before wrenching yes?
