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.

      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?

      Just bought 06 KingQuad 700 and first ride out hit a mud hole, not to deep and it shut off and would not start. 
      Got it home and found the spark plug hole was full of mud and water. Went and bout a new spark plug and began cleaning it out. Put a deep socket in there and it wouldn’t grab. Took a pic with my flash and this is what I see. Any suggestions? And what is it??
      previous owner said it had a new coil so that’s why I decided to change out the spark plug, also ordered new coil should be here by the weekend.

      I just got a 1991 Yamaha Moto 4 for my son and I am looking for a service repair manual. I know that the timing chain needs replaced.

      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.
