the can-am BRP clutch is known for eating belts, and when coupled with the weight and power of the commander, it is going to be an issue. i have seen multiple commanders blow a belt before 100 miles. not necessarily the owners fault, so dont blame yourself for riding the machine too hard. it is purely the design of the primary clutch. it is inevitable. i have a whole new primary clutch that fixes the issue.
we havent had any belt issues with the canam atv clutches or belts,but one,do to 1/2 gal of mud and swamp water in the coves lol,now the sleds diff story,but then again if you stay on top of them your good,they have alot more kevlar in them now for the incress POWER,We have done many mod and pro mod drag sleds and the new belts handle well over 250 hp with no problems,
the sled clutches are different than the ATV-UTV clutch in many aspects, and can definitely handle power alot more easily than the ATV-UTV clutch. the ATV clutch is designed with a 2piece primary that will spin independently, meaning the inner and outer sheaves will spin and rotate differently from each other. under serious power or load, the clutch will slip the outer sheave, glazing and roasting the belt. on high HP machines, upwards of 70hp, the clutch will actually slip so bad that the outer sheave will tighten the primary bolt up to the point of over tightening the bolt and snapping the bolt off in the crank. i have seen multiple machines do just that.
Airdamm dont take this in a bad way,but you are wrong about the primary and secondary clutches,it is physically inpossible for the primary to spin in differnt direction,unless you take it off and split the 2 sheves,i have been building cvt clutches for over 15yrs,
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
the secondary however you are right about. they do not have any problems slipping. they are splined together and only move in and out with each other. there is no way for the secondary to slip or spin in any way opposite of each sheave. the primary however will. the inner and outer sheaves will spin and rotate in different directions of each other without a doubt.
I sent you a PM and an email to your company. What I would really like to do is call you and talk to you about an order for my Commander.
