My name is wes i have a bombardier ds 650 and when i put it in gear the trans does not enguage. I started with the clutch that seems to be in good shape. When turning the shaft that the clutch basket is atatched to when the motor is in gear the tires do not turn. It is like it is in neutrel in all gears. I split the cases hoping to find some broken parts but i see nothing wrong. Can some one help me out here. Also i went to put the cases back together they do not go all the way back togerther. Every thing seems to be seated properly but cases wont go all the way back together.

 

You most likely have bent shift forks, its a common problem with the DS650's. They are really good instructions on how to replace the forks and getting everything back together. Here is the link:
