Ran into a G60 swap on the cheap and was going to use the charger on a different setup. After finally removing the charger, I find it has shaft play. What I'm wondering was if this was normal? Im new to the supercharger scene so i dont know if its the same as turbos. I'm pushing and pulling on the shaft that goes to the pulley and it has perhaps quarter an inch or so of play. Any info is appreciated. Thanks.
