Does anyone know what size star-hex head size is needed for the tensioner on a series 2 ?

I think my coupler is bad , but after searching the archives, maybe my bearings are bad too ? I've been hearing a loud high pitched squeal(not like a belt sqeal though) coming from the snout area of the supercharger(just started today). I can hear it at idle and while driving at low speeds. It disaapears a little while driving , but its still there. Is this something I need to replace ASAP , because I won't be able to fix until next weekend , and will probably add another 600-700 miles on it.

Has anyone bought anything from www.rollingperformance.com ? Fast shipping times ?

It won't actually sieze most likely. You could probably put a couple thousand on it without it getting really bad.

I bought my rebuild kit through rollingperformance.com. I got the kit in about a week, and I couldn't be happier with the improvements that it made.

I just ordered the full kit from them too. Yesterday. We'll see. And I mean FULL kit. Everything but the coupler. ALL bearings and seals.
