A lot of folks don't realize that they need to use LOW gear more on belt systems. YES, the 850 has tons of power, but when driving at slow speeds and doing technical trails, LOW gear should be used. In the XP line-up...driving up to 20 or 25 mph in LOW will do no harm to the system. Glad you got it identified and fixed.

My 2019 850 will actually prevent you going any faster than 30 in low gear by governing it.

I have had the same problem. The belt is getting either loose with slack or the grooves in the belt are getting word down. I advise getting the belt checked because mine did that but now it does. I have a Polaris 570

I have a noise that happens every time I slow down on my Atv and I don’t know of its someone with the engine or something else but I don’t know what it is can u help me? I have a video of it on my channel (2 actually) about two different noises

Mine made a similar noise, and then promptly broke down on the side of a road. Absolutely SHREDDED my belt, somehow sent chunks of it up the clutch box breather tube and littered the road behind me in 1-2” belt chunks.

Bro your a bad ass my atv i just dropped 3500 on was doing the same shit I was devastated. But I checked my belt and its fried it spins it but it won't grip it enough to keep the rear trans spindle from bouncing

hey i see the video of your sportsman 850 drive terrain issues jw what you had to do to fix that.. was it the belt or axles or differential problem?

Belt! Watch the video

I’m having the same problem but I’m on RZR XP TURBO 2016, it sounds like that when I’m start to run but then everything fine. “ when I reach a consistent speed “ no noise. Put in reverse gear and hear the noise when going slow then same “ no noise after I’m driving a consistent speed “ even if it’s 10-15MPH no sounds. Basically it’s just when I’m start to drive slowly. I do burnout and hard pulls. Do you think it could be the belt? Or ?

Yep, but only one way to find out. Take off your protection cover and inspect the belt.

Did the rear wheels jump during this clinking sound? My 12 850xp is doing that same thing and it causes the rear wheels to jump when taking off.

Clutch is gone,,the one that holds the weights and spring,need to replace the belt as well..lift your seat off,,the rubber boot on the clutch intake pull it off and put 2 layers of tights over it and tape them on,this stops a lot of dust getting in there to the parts that move and it's that what's caused your wear or you've been going in water to deep

Polaris,where do we start,so many things cause rear end problems and noise,,wheel bearings that are on the way out are quiet when first used but once warm start to make a grinding noise where a drive shaft will do it from a worn brake pad,disc or caliper can cause noise but to see this check pad wear is even,a worn prop causes a knock on set off but no slip in the rear wheels and anything belt or clutch related is, a slipping belt will need more revs to get it going and will not make the wheels stutter in a juddering motion but if your clutch is gone then(the one that holds the weights and spring )the back wheels will have a stuttering/juddering from them on set off,,I've got a sportsman xp 1k,good sides,flying machine that climbs hills even legs would not walk up with out using your arms,,bad side,hubs wear easy,suspension bushes no good,a arm bushes no good,constant wear in all the drive gear so need greasing up every 200 miles,that's bearings,prop joints,gear selector joints,lift your seat off,,the rubber boot intake you see pull it off and tape 2 layers of tights over the end and this stops a lot of dust getting in to the clutch and doing the damage your getting

Ive been pushed down large rivers that kayakers should be on and you cant even hear the motor running but she keep going.

The video does say and how to fix. The clucking noise was caused from the drive belt. It was severely Burnt from the previous owner doing burn outs in his drive way..There was shinny spots /burns spots on the drive belt. I replaced the drive belt and it went away. Never had another problem with it.

I get on a flat, or go uphill and it doesn't grind... NOTE*** this machine has spring-like things going over the front break-lines and on the wheels as well... I can't figure out if those are binding. it really sounds like one or both sides are binding when I'm headed down-hill...... Not sure... Have you ever heard of this....? Thanks... Al

I never had this clunking. I bring it in for my first service and I get it home. I test ride it , and it clunking. Not as loud as this but it clunks whenever u change gears from Low, High Reverse. Also clunks when coming off throttle in any gear. Do you think this is still the belt? It didn’t to this until the idiots at the dealer serviced it and the belt has 27 hours on it. Thoughts....???

@mogyver69

6 жыл бұрын

well if the idiots at your dealer decided to do burn outs in the parking lot with your ATV during a test drive then I would say yes.Sometimes just hitting the throttle hard on concrete during exceleration can cause the belt to slip and put burn spots in it. So it is possible.

mogyver69 this dealership is sooo stupid. I don’t doubt it. I can go on and on with things they’ve done. I only went there because the next polaris dealer was far far. And ty for getting back to me so quick. One more question. Is this clunking in ur experience always the problem? Because I do notice all sportsmans do it. Some worse then others. Mine didn’t until I got it back from them. And I’m meticulous with my stuff so I know it happened there.

That sir sounds and looks like a trans gearbox issue. I got a brand new one clunking on day 1. There is a flywheel in the trans that has play and clunks. My theory is this play over time wears it out. The gearbox is out of synch due to slop in the gears.

@JohnnyRebKy

Search the video of a trans tear down where the guy shows the slop in the trans flywheel. When pressure is applied and released the play in the flywheel gear clunks. Then dealers tell new owners these noises are normal. Then down the road end up like you where the slop on that flywheel gear throws the whole system out of synch
