Not quite true:It's not hat straight cut gears are cheaper, they are stronger. I think it's the lack of any real adjustment in back lash, this setup comes with one shim to set the ring gear to the pinion and that's it, there's no real way I can see to measure or add shims or remove any to set the proper depth of the teeth, due to the split case, so it's hit or miss. I haven't ridden the 2013 yet to see if it has the same noise, I'll check this afternoon.My 12 makes the same noise and I have read many posts that say its because polaris cheaped out and went with straight cut gears like in old suzukis and other older bikes. I have almost 1400 miles on mine now and it still makes the noise.
No, my 2011 and my wife's 2013 850 XP both have the noise.First time ate owner here, I've had a ranger 500 crew for 2 years and love it. Use the ranger around our property for utility but wanted something to trail ride with and still have a bit of utility left in it so I got a sportsman 850 xp. It's a 13 don't notice any noises but I'm a noob. Did 40 miles Friday on some rough trails and the thing is a beast. Is this problem limited to 11 and 12's?
My front diff was dirtier than I thought it would be. I changed out at 10-15 hours as well.I have over 200 miles on my 2013 850 and may have heard the noise once. Anyway, I have ten hours on the quad and decided to go ahead and change all the fluids on this thing out of concern. Let me tell you, I'm glad I did. The diff oil front and rear was terrible. Full of metallic powder and nearly black. The magnet couldn't have held anymore. I'm going to change it all again in another ten hours.
I think they've all backfired for a little bit when brand new. It will go away after you run it more.I have a 2013 850 xp and I noticed the noise after about 5 hours of riding it. it has also back fired 2 times and it will scare the living shit out of you when it does.
LMAO!! The first few times mine did it scared the living hell out of me too!! After about 250 miles mine stopped doing it and I'm glad lolI have a 2013 850 xp and I noticed the noise after about 5 hours of riding it. it has also back fired 2 times and it will scare the living shit out of you when it does.
That must be what's wrong with my 850...I haven't checked the DIFFERENCE oil!I also would like to suggest you that you should check all fluid levels of your 850XP, my rear difference had very little oil in it you can check by yourself and fix it if there was pretty loud, checked it right away and changed it, In this way you can resolve your problem..
