[mudthug_814]

alrigt as some of you know that have read and seen my video i have a 2000 polaris scrambler 400 4x4 that has a whining noise on when in drive now some of you said check the the transmission fluid, but apparently in 2000 polaris did not make a check\fill spot on the transmissions and also i couldnt even find a drain plug, next some of you said to pull off the clutch cover and look for excess amounts of dust, i did that and to my suprise there was nothing its a brand new belt dang near no dust to speak of and with the quad off i played with the clutches there is no give slack or grinding i also with the quad off put it in gear and there was still no grinding or anything next i started the quad up with it in nuetral i reved up the quad no whining jack the rear of it up put in gear and throttled it and there was the whining could it be one of the following, now when i got it he told me it needed rear axle bearings and i noticed he packed it full of grease could that be the noise im hearing or i also noticed that the front sprocket is really loose could that cause the whining noise some one please help if you want to see the video where you can hear the noise its on youtube the title is mike 2000 polaris scrambler 4x4

does anyone have any ideas

may have to remove rear skid plate to find tranny drain, fill plug should be on right side above sprocket or if it has a dipstick you fill it there, could be rear axle bearings, if you jack it up and spin rear tires by hand you should be able to tell

alright thanks russ ive pulled the rear plastic, air box, so i can see everything and there isnt a dipstick or a plug anywhere on this transmission i didnt pull the skid plate to see if there was a drain there im off tomorrow im gonna check the rear axle bearings tomorrow

To find your fill plug on trans. you need to remove the bottom plastic cover by pull start. The one that goes from front to rear of floorboard. The fill plug is rite behind the output shaft for front driveshaft,it's a 9/16 or 14mm(both sizes fit). The drain plug is on the other side,lay on the ground on your back and look in between the steel brace with 2 cut outs underneath the trans. it's a 3/4 or 19mm(both fit). You will need to use a wrench on drain plug because it's a small cutout.

alright heres the update found the fill plug thanks to scramblinman its full while it was still jacked up with out the quad running i turned the rear axle and there is an obvious squeak coming from the rear axle bearings so i think i got it figured out thanks to those who have helped
