2007 Yamaha Kodiak 450 4x4 Stuck in gear... Please help

[Charlesawest936]

Hello im really needing some advice on where to start for the problem im having. I know that iv got to pull the motor and split the case but is there something i should be looking for? Im guessing its not a very common issue with these bikes because i cant find a single thing online about anyone else talking about it. Anyways my issue is i bought a 2007 Kodiak 450 from a friend whom said he was hauling a** on it down the road and all of a sudden the back wheels locked up. He pulled the rear diff and it seems to be ok i cant spin the rear prop shaft at all no matter where the shifter is.

Well I'd try taking the belt off first, that will confirm it's the gearbox.

 

And can you disengage the front diff ?

Ill try taking the belt off but i finally got the bike running today and it runs really good i did notice that with it idling its just fine but if you rev it up a bit it starts to make a clunking sound almost like its trying to go into gear and it doesnt matter where the shifter is i cant get it into low gear though. And as far as the front diff goes i havent been able to turn the front driveshaft but the bike will roll because i have the rear diff removed.

I was really wanting to know if is this a model with a front diff you can disengage ? Or is permanently in four wheel drive ? If you can make it into two wheel drive try it like that...

It's sounding though as if it is a problem in the gearbox..  You could drain the gearbox oil and check for metal chips, or chunks..

Well i ended up finding the problem the other day. After getting the case split open finally i found 3 different gears that have teeth broken off of them. Everything else looks good. I was lucky and was able to find someone on ebay that was selling the complete transmission gear-set seriously for $40 with free shipping. So i ordered it and the complete engine gasket set so that i can get it put back together
