Is this normal for a procharger?

Do you think that is normal? If so, leave it be. If not, tighten the bolt holding the pulley on.

It seems like it’s normal but when it sits where it wants to the pulley is off. It is a aftermarket griptec so maybe it was installed wrong or needs a washer but the belt does not seem happy.

Kind of looks to me like the shaft going into the Supercharger is moving, not the pulley itself. Take the belt and pulley off, then thread the bolt back into the shaft so you have someting to pull on, and see how far back and forth the shaft moves. Im sure there is some allowable endplay (more so if the gears are straight cut, less so if they are helical) but either way that is not normal. If the pulley is moving on the shaft, you should see scuff marks on the shaft. Also, When I first installed my Griptec pulley on my 2017 setup, the hub that Griptec provided was incorrect, causing a misalignment (not the back and forth that yours is doing) They sent me an updated one with the correct offset shortly thereafter.

It is definitely play in the shaft of the procharger but it seems I may have the same problem as you of having the wrong hub. I called procharger and they said there should be some play so I guess it’s okay. Did you call griptec to get the hub?

Take the pulley off, check the shaft play, compare griptech hub offset to original pulley.

Yes, just call them and tell them what you have. They gave me a new hub because I purchased the pulley and hub from them, but Im sure they can sell you just the hub

Found the old photo I sent to Griptec.

As you can see, the hub section of the Procharger pulley (all one piece) sticks out maybe an 1/8 inch, whereas the Griptec was flush. The revised griptec hub is exactly the same dimensions as the Procharger pulley

You’re a life saver I have a new one coming from griptec. Apparently I needed the snub nose and not the regular.
