This was after we were unable to release a dog gear, even after greasing it and pulling it by hand. I don't know if there are any good pictures of it, but if you're at IRI, you can come to our pit and ask us about it.

In a nutshell: We un-mesh the gearbox by attaching the motor side to a plate that moves to pull the two gears apart.
I was thinking about this, and the way you guys did it inspired another thought for me:

Make a slot in the gearbox where that final gear is so that the gear can slide, and then have a pneumatic cylinder attached on either side of the shaft. When the pneumatic is at one end, the gear meshes. At the other end it disengages and you get a kick. That shouldn't take nearly as much force.

(The slot shouldn't be too hard to figure out. Just something following a line at a smaller angle than that of the line tangent to the pitch circle of both gears, right?)
