I have a 2009 RZR S with a MCX turbo. It's been running great up til now. The Primary's clutch bearing located in the moving sheave has moved; not allowing the the sheave to fully retract, thereby keeping the belt engaged. I understand that this is an inherent problem with the 2009 clutch and has been corrected in the 2010. QUESTION: Can a 2010 clutch be used in a 2009 RZR S?
