drive clutches on an iqr 600

The 2008,2009,2010 600R has the larger PTO end(33mm) like the SDI engines(it shares the same crank as the 800SDI).

The 2008 600RR has the 600HO engine and uses the smaller PTO end(31mm)(440IQ/500EV/600EV/600HO).

So to answer your question, no not all the P85 clutches will work. If you try and slide the small taper clutch on the large PTO end it will not go on far enough.

The large taper clutch part number is #1322746(600R). The small taper clutch part number is #1321928(600RR). I hope this helps.

Nicely written "IMBROKEN". I second that.
