sir, i can assure you, the factory BRP clutch installed in the outlander 400, 500, 650, and 800, along with the renegades, and commander, are all the same clutch, and the inner fixed sheave, and the outer movable sheave are not locked together. the outer primary movable sheave has no way to lock itself to the fixed inner sheave. there is a tapered seat inside the shaft of the fixed shave, that the spyder also has a tapered male end that seats into the clutch. the spyder fits down on the movable sheave and the tapers of the shaft and spyder are the only things that hold the outer movable sheave to the inner. as you apply too much power to the clutch, the inner and outer sheave will rotate independently of each other, also if you will remove a clutch off of one of those machines you can also see that as the one-way bearing in the base of the clutch engages, it will also rotate the outer movable sheave about 15 degrees counterclockwise of the inner fixed sheave. you may have done alot of snowmobile clutches, or other types of atv clutches, but this one BRP has on their can-am ATV and UTV line WILL rotate independently and it is the reason the can-ams are so rough on belts
