Hello all! I'm new to this site,just signed up.I've got a question that I'm sure somebody out there has an answer for.I've got a 2003 Artic Cat 4x4 with a 492 engine.The engine family number is 33AXX492AA .The question I have is about a knocking noise coming from the rt side. I've been told that because the piston has such a short skirt that it rocks in the cylinder. The quad doesn't have a bunch of miles so I don't think it's worn that bad. Any opinions or suggestions? Thanks

 

Does it spit and sputter too? May not be getting enough gas.

 

well i know in that year there was a bolt in the belt housing that was coming loose and would create a knock or loud noise. Not sure if it was heard mostly on the left or the right side but id assume where the belt is(if its automatic). I remember it being an easy fix. thats all ive got for ya.
i had a 2002 model 500,same as yours,and it was bullet proof. sold it with 5,500 miles on it. it was a manual shift though.

 

The noise seems to come come more from the rt side.It is an automatic. You can hear the noise at idle but it seems more noticeable under load. I'm just a little nervous that it may be a bearing.

 

Mine makes a noise also its a 09 550 750 miles.It had me wondering one day,it sounded like a bering but I thouhgt not.Now Im leaning towards a clutch noise.I dont know what it is,sounds like a knock.You can hear it loudly while ideling and under load when you first take off.I'm thinking there is nothing wrong with it,but wish I knew what it was.Strange.

 

Dealer said the noise is the clutch.Not to worry about .

 

Thanks
