My 2003 ski-doo 440 mxz X Rev blew the clutch last week. Been trying to determine the bore and taper size and find a clutch that might fit. When I measure both the PTO and the clutch bore, it measures 33mm. Everything I read and hear is that clutches are 30mm with 1:7.5 taper? Mine isn't at 30mm until you are halfway down the taper. But measuring the taper does seem to yield the 1:7.5 taper. So should I be looking for a 35mm clutch, or a 30mm clutch? Maybe I am not understanding this right? I understand that this should be a TRA2 clutch as TRA3 clutches didn't come out until 2004.

So what ski-doo primary clutches ARE 33mm for the bore size? I have read a lot of conflicting info...

Thank you for any help you can provide.
