1995 Yamaha Big Bear 350 Front Wheels Do Not Spin

Recommended Posts

i just want to say hi first off. i just got burned bad on a quad. 95 yammy bigbear 4x4. anyways, i get home and get stuck. front wheels dont spin. first i thought that the cv joints are gone. find out after tearing front end apart that the gears inside the diff will turn when you turn the yolk by hand. as soon as you put the splined shaft of the cv joint into the diff, and turn the yolk going into the diff, the cv's on both side wont turn when you hold them with your hand. im baffled as to whats wrong. i pulled the diff apart and took out the big gear and disassembled that gear. in side that gear there are three rings that have like a checkerd pattern on them. the outer one looks to have the pattern worn off. are these some kind of clutch plates or pressure plates that lock up the cv's and make them turn? if you spin the yolk that goes into the front diff and look into where the cv's go, you can see the spline turn. as soon as the splines on the cv shaft go in the spline inside3 the diff stop turning when turning tha yolk by hand. please help. i payed 1500 for this thing and after having it for 2 hrs, the guy tells me go to hell.

That's odd and that sucks that the guy wouldn't do the right thing. Did you try disengaging the 4WD and then re-engaging it?

Sounds like your front diff is toast man. Have you taken the actual differential apart? There should either be a bunch of gears inside, or something that looks like a clutching system of sorts. Either way, it sounds like you need a new one.

      Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00.  It's been sitting outside with no carburetor on it for about a year.  Its rusty, missing some parts, wiring is all cut up and spliced etc.  No seat, no racks but the plastic is all there minus the headlight housing.  Anyway, who can pass up a $40.00 quad right?  I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water.  I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine.  I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark.  Did a quick compression test, 70 lbs.  Wet test bumped it up to 90.  Ok, so rings and cylinder washed out with water for a year, not too surprised.  I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show  it's got life.  Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either.  The compression is now around 60.
        Anyway, my question is....is it worth it to try to get this thing going?  I tore the top end down today and the cam and one of the rockers is pretty worn.  I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well.  Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again.  Much less just to make it run and use as-is but I won't really like it until it's right.  I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
      I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much.  I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down?  I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
       
      I'll get some pictures today if anyone want to see them.
       
      thanks!

      Hi, I'm a newbie on here.  I just got a 2007 Suzuki KingQuad LT-A450X.  Are there any specific issues to look for on this model?  Any specific maintenance to do other than the usual oil and filter changes?  
      Thanks

      hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.
