91 big bear tranny, or rear diff? or transfer case?

Recommended Posts

just bought a 91 big bear 4x4. if i go too fast it locks up and the rear wheels will not turn.

if i put it in reverse and back up a bit it "resets it" and i can keep going.

does this sound like a tranny issue? diff issue? or transfer case issue?

i will tear it down but if you guys have an inkling of what could cause this issue it would give me a place to start

regards, VikingTrad3r.

      Can you believe this thing blew a new head gasket after a few weekend rides? Granted, it was beat on in a mud hole every weekend, but this is a new head gasket on a 400 Kodiak. Bummer.

      So my friend was riding this and all 4 wheels locked up and had to be slid out of the woods. We put it on the trailer and and left it alone thinking it was ice.
       
      So he drove home and as we drug it off the trailer “snap!” Started rolling again. I told him to leave it since it’s rolling and we can figure it out
       
      I’m not close to the machine to try things or even work on it. Buy anyone have an idea. I was thinking ice like mentioned. But nothing was leaking to indicate a broken case or seal. And the fact it rolled just by bouncing on the trailer. Very confused

      I have a 99 Kodiak 400 4X4 that I picked up for $300.  The previous owner had modified the foot shifter by welding a piece of rebar to it so he could hand shift while plowing.  As you can imagine, the allows for much more torque on the shifter than it was designed to have, and he broke the stopper off of the the shift mechanism.  No big deal, I ordered the part and put it back together, went through the carburetor and off we go, it runs pretty good.  
      The first thing I noticed is that when I put the shifter all the way down it goes into reverse, I'm supposed to twist a knob to get it to reverse but this seems to be disabled.  Also, once in reverse, it's a bugger to get back out.  I have to hold the shifter up, then quickly back down and up again to get it to come out.  All forward gears work fine, clutch is tight, no problems.
      The reverse cable and lever are in tact and seem to move freely.  
      My question is this:  What does one normally have to do to get this thing into reverse?  I assume put it in neutral, twist the knob, kick the shifter down.  Does the brake need to be applied?  I'm not sure what's going on here, I suspect it's been 'modified' as it goes into reverse without the proper precautions, just not sure if the mods were external on internal.
       
      thanks

      Trying to replace the carburetor on my 2003 Bear Tracker 250. Two brand new carbs in a row from different suppliers.   Both leak fuel out over flow and intake as soon as I turn the gas on. Any ideas. Am I doing something wrong?

      I picked up a 1997 Yamaha Big Bear 350 2X4 a week or so back in non running condition, apparently they said it needed a new carburetor or a battery, I cleaned the carburetor thoroughly and got it running on idle and without choke now and it shifts into all the gears even into reverse. Aside from making me bounce a little when trying to start out with a bit of throttle the shock suffice to say needs work. Anyways I made a video of it running and would like your opinions on it, as to how it sounds while running. It seems like it has a little whine I'm not sure why that is maybe someone can tell me what it is. Anyways here is the video.

      I have a Yamaha Big Bear 350 and the reverse doesn’t work, it shifts from low to high easily but it won’t go back to reverse. I’m new to this stuff, so I’ll take any help. Any ideas?

      Hello all, 
      i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible. 
      Here’s what I know:
      1. compression 120psi
      2. all timing marks are lined up after numerous revolutions. 
      3. Strong spark. 
      4. Valves adjusted correctly. 
      Thanks in advance.
