Tech question for the gifted on repairs on a 97 xplorer 500 4x4

[Khaosaudio]

I HAVE A 97 POLARIS 500 4X4 EXPLORER. I JUST BOUGHT IT TODAY. THE BIKE WOULD GO INTO GEAR WHILE I LOADED IT UP. IT ROCKED AND WOBELED BAD WHEN I DROVE IT AT HOME AND MADE A CLACKING NOISE. NOW IT WILL NOT EVEN GO INTO GREAR. I MANAGED TO GET IT IN TO DRIVE BUT HAD TO GIVE IT QUITE A BIT OF GAS TO MAKE IT GO. IT SOUNDED LIKE IT WAS SLIPPING IN AND OUT OF GEAR. THE MAN I PURCHASED IT FROM JUST REPLACED THE REAR CV SHAFT ON THE LEFT SIDE BECAUSE HE SAID HE "SHATTERED IT" . THE FLUID IN THE CASE LOOKED NEW AND WAS FULL. OH YEA, WHEN I STARTED IT UP IT ALSO MADE A FUNNY WINING NOISE. ANY SUGESTIONS ON WHAT MY NEXT MOVE SHOULD BE.

Check the oil for bits of metal. If this is a cvt bike remove the belt cover and check the pulleys and belt. Last put the bike on an atv jack and run it to check for the noise. Use common sense when doing the last check as rotating things and fingers never mix

Well the motor runs like a champ. fires right up. Even with the motor running great would there still be an issue with the shavings in the motor or should i lean more towards the pullies and belts? Its just crazy, when I drove it at a about 10mph it started rocking like i had a bent rim while making a clacking noise in the rear end.

Check the cvt first. Should be a cover on the side. If ok then jack up the atv and spin the rear tires and see if u can duplicate the noise.

If there is shavings in the oil then yes the motor is slowly destroying itself. I am not sure if your atv is a 2 stroke or 4 stroke If it is a 2 stroke then there isnt a sump for the oil and therefore you wouldnt be able to check the oil.

What Can I do to stop it. Its just weird, it fires right up, runs real smooth. it only makes the noise when i put it in gear.

Check those axles and hub bearings, my friend used to have an xplorer and he went through a bunch of them. One time we were screwing around in the snow at a shopping center and he hit a shopping cart with his tire...blew out the axle . There were a few times on the trails with issues also.

[marioweldinginc]

If it happens when the vehicle is stopped then its possible its an internal engine problem. If its only when its in motion then Id have to agree with Ajmboy as I was giving general help that could be applied to any atv

Did you figure it out? in addition to Mario and Ajmboy, I have some suggestions... Find out WHERE the noise is coming from: pvt, tranny, engine...You did'nt say where the wobbling was from: front or back? I'm assuming back since the cv was replaced. Had a friend who's sportsman did the same thing it was a combo of low tranny oil and bad rear differential. Also check the inner and outer seals of the driveaxle it will make clicking sounds when turning..if all else suggested fails. Note on the pvt: pisses the machine off when anything gets past the outer cover ie: water, dust, dirt oil, etc so check the seal, learned that myself the hard way powerwashing the mud off.......bike would not move and howled mad.....hope you get it fixed soon:wink:

yea, come to find out the driven clutch as*. can apart as soon as I took the cover off. The nit witt who changed the drive belt cross threaded the part that screws on the shaft thingy. it was wobbling so much it ripped the threads up. this was why the bike was shaking so bad. This was a good learning exp. for me and a good teaching tool for some one else. Thanks for the advise...
