Front Dif Stuck in 4 wheel drive

I have a 2006 660 and the front dif stays locked in 4x4 mode. The digital picture showing the 4x4 mode goes out so the electronics seem to be working. You can here the motor when you push the 4x4 button but it does not release. I am a novice at ATV's but am mechanically inclined. Any help?

I see that a servo motor might be available somewhere, but does anyone know if any other internal parts are such as gears etc. I have not yet taken it apart, but when I do this weekend and if I find some mushed gears it would be good to know if I can get parts.

Anybody have a unit for sale? Can only imagine what Yamaha might want.....

So I pulled out the servo unit and tested the unit and it rotated the gear np. I also slid the pin back and forth and with the wheels off the ground it unlocked and relocked the front diff, so np. So I set the 4x4 switch to unlock the 4wd, slid the pin on the dif over to the unlock and put it all back together (and did a much needed diff oil change). Works great, tried it better than a dozen times during a very fun and wet muddy ride and np. It worked great.

So maybe the pin over shot the gear? Dirty front dif fluid (with water in it), not sure, just happy it is working and not costing me $400+ for a new servo.

Is there a good way to flush out the dif? I ran through almost a liter of diff oil before it started coming clean and will run this for only a couple of rides and change the oil again.

Would draining the oil out and putting in diesel or other an other lighter type fluid work to give it a good flush out?

Thanks for all the help so far, this is a really great site.

I have the exact same problem. Did you end up finding where water was coming in from?
