Hey-
I'm not really that educated about ATV's, but i have a polaris xplorer 250. I recently got it registered, and am enjoying driving somewhere other than in my own woods. But recently the atv has been making a grinding noise. It sounds like its not in gear all the way, but even when i hold the shifter forward it still makes the noise. It is not constant, but usually occurs when i am accelerating or driving up a long incline. It is coming from somewhere inside the engine or transmission area, not from a hub or differential. Any suggestions as to what it might be would be appreciated. Thanks
Tyler

 

ok, I like to do things myself, but if i was you i would take this to an expert, You most likely have a shot tranny, which is somewhat costly to replace

 

where does it sound like its coming from.

 

I havent been able to pinpoint the noise- it isnt constant, and it never happens when im waiting for it of course. I havent done much rough driving, though. Just light trail riding over packed dirt and some light snow, and i use low on the big hills and deep snow.
When im riding, it feels like the noise is coming from right under the back of the seat; right under where im sitting. But there isnt much there on a 250, so i dunno. And i can feel it too, the atv kinda jerks a tiny bit, which makes me suspect a transmission prob. Its only two years old though, and like i said, no real off roading on it, just light trail riding...

 

is it still on the warranty?

if so see what the dealer says, sounds like a tranny problem if it is jerking like you said

 

Thanks for your help... i'll check the warrantee, but i dunno.. the 250's the cheapie one [img]i/expressions/face-icon-small-wink.gif[/img] I think ill get it to the dealer and see what they say.. *cringe*

 

Check the chain...it can make a grinding noise......could be way to tight..or loose...check the sprockets also....just a thought

 

Definitely check your chain. I have a 2001 xplorer 250 and the same thing happened on mine. The polaris chains seem to strech very easily and when your chain gets loose it makes a noise from hitting the sprocket wrong. Check your chain before every ride!

 

thanks, will do the next time im outside... lotta homework today [img]i/expressions/face-icon-small-sad.gif[/img]

atvguy, u think it could have anything to do with the cold we've had this winter up here? i was out when it was a good bit below zero a few times [img]i/expressions/face-icon-small-happy.gif[/img]... just wondering if it could do anything

 

if you rev the motor in netural and don't let it rev down when you shift into foward it wll grind until the rpms are down enough
