BRP told my dealer it needs to break in. If at 10 hr it still does it they will change it. All models made after Sept. are supposed to have been fixed. Consists of new spring and helix. I can say that mine has gotten much better, but I only have 3 or so hrs on it.
Well 166 miles and 13 hours and clunk is still the same maybe I'm not running it hard enough?I wish I had a way to send you guys a picture of some of the stuff we go through up here cuz it makes 13 hours look and feel like 130 hours.We have coulees up here that make ya dizzy just lookin down them and the commander went there with no problem way more places then my 700 prowler would think of going but still I have the clunk and not getting any quieter.
If it does get better with more use as I suspect it will, it will only seat in better when you rev up and hear that clunk...driving it after engagement (the clunk) isn't going to have near the impact to seat the helix with the movable sheave to rid it of that noise as simply reving up to the clunk time and time again.......purely speculation on my part.....but I think I know what the clunk is and how the parts in there work together.....time could prove my theory wrong tho.........or right.......Lance
I can understand the clunk as if going from fw to rv or vise versa but why when u start out in a forward gear, my 800 skidoo snow buggy doesn't do that, and it operates on the same exact principal, and even the sleds with fwd&rvs do not have that clunk.Makes ya wonder.Ah but things that are in the dark are meant to go clunk, according to my grandma.LOL LOL:giggle:
When in gear and you start reving up the engine, the primary starts grabbing the belt and moving it upward into the sheaves "V" off of the one way bearings collar (an idler)....it's increasing the distance the belt has to travel per engine revolution on the front pulley....
As RPMs build and the belt moves up more and more in the front primary "V", it has to move the same amount downward in the rear secondary "V"....this slides the movable sheave into that helix that is splined to the tranny (maybe 1.5" or so of quick horizontal movement).....when the sheave moves over that distance, it totally engages the helix (that is the source of noise I'm thinking of is this engagement process),,,,thus your machine will start to move......
Each time that helix gets hit by the movable sheave, it (helix) will wear and mold itself to the sheave ramps and backside a little more,,,the 2 parts will seat together as a smooth sliding and engaging unit,,,,after this happens a few hundred times, the 2 parts should "zen" together and not make much noise at all
Of course, all this front and rear stuff applies to our Commanders and not a Rotax converted Rhino as the engine in these are facing backwards!....:)....Lance
I have 300 miles on mine now and the clunk is nearly gone.
