Neat piece of info here IMO: with you Commander idling, lend your ear to the opening for the CVT intake .....this is the longer, narrow slot on the driver's side at dash height......

I noticed that I could hear the belt whirring and the one-way bearing pins clicking....this will sound to alot of you like something is broken....it's a very quick-paced click,click,clicking sound, (slow-paced buzzing) ........everything I heard was normal....

Take a listen to this now, especially how loud the clicking/buzzing sound is.....then try to compare the loudness now when new to regular maintenance intervals from now....this may help us decide when to pull our one-way bearings out and grease them with the (infamous and expensive) isoflex grease..........Lance

**EDIT** You can also hear other neat sounds from the opening also,,,,like a burnt or glazed belt complaining at ya.....video below:

that squeal from 2,000rpm-3,000rpm does not sound normal. i have never heard it on the ATVs. it doesn't quite sound like a belt squeal. it sounds more mechanical. the normal belt noise at low rpms is more of a whirring sound, the clutches moving lots of air. your sound is different, which it shouldn't be since the clutches on the ATV and commander are the same

That's for sure!....that's why the last sentence described the burnt/glazed belt with that video...

BLR and I had 2 Commander/Rhino full-on 300'+ drag races last Sunday, first in 4x2 and the second in 4x4,,,,after those drags, this was the noise....I think it was an extra-hot belt Adam, because it got quieter and quieter later in the day and was totally gone that evening.....another testimony that the Commander needs LOTS of clutch-work, not just a bit of fine tuning like you say too......but since I have access to the CVT cover right now, I may pull it and have a look-see at things anyway.....maybe pull the bolts to make sure it's not stretched like Razorback Dave's...that's scary stuff!!.........

BTW, while I was fishing on YouTube for a few videos for my CVT thread, I ran across no less than a dozen vids with the CVTech clutch......you might get an arsenol of those vids together and post up??.....just a thought.....Lance

yeah that noise could easily be a glazed over belt squealing. if you take the clutches apart, it would be wise to take a 120 grit sand paper and rough up the faces of the clutches to somewhat eliminate belt slip. it wont hurt the belt one bit, and it will give the face of the clutch some "traction" so the belt can grab and go rather than slip. just go from the bottom of the sheave to the top of the sheave, do not go in a circular motion.

it would also be wise to take the belt and soak it in warm water with dish soap and use a red scotchbrite sanding pad to scuff the sides of the belt up getting rid of the glaze on the sides of the belt. get the belt good and warm, and scuff the sides of the belt with the scotchbrite. it will take the glaze off the belt and recondition it. it wont make the belt like new, but it will get it as close as you can get.

Thanks AIRDAM you just saved me a little money for now......But I can tell yeah that you will be getting some of it soon enough...for a new clutch setup.... Barbara

That's my MO exactly as you mentioned on the sheaves except I wipe them down first with brake cleaner....never had tried to resurrect a belt like that, so will do it.......Lance
