Re: DeWalt Transmission questions

The chuck is threaded to the gearbox, a right hand thread. The left hand thread was only for the retaining screw with the torx head. (Tristan beat me to it...)

The pictures I found only show us clamping the entire drill assembly to the table. I couldn't find anything that showed our lever arm. But, I'm not sure what kind of wrench you broke, or how. The chuck can accommodate a 1/2" bolt, so I would suggest chucking up a bolt that size, getting the biggest wrench you can on the head of the bolt, and go to town. When it breaks free, you'll know.

Heat can also be your friend here. If you have a small torch, you can heat up the outside of the chuck, and be very careful not to heat the gearbox, the housing, etc... But, I would only go this route as a last ditch effort.

Team 1213 used some pretty small wheels, 4", which gave them about 5-6' per second in low gear. I'm not sure that they actually shifted the DeWalts. If they did, they'd have a theoretical top speed in the 24fps range. Anyone care to comment on this, or did I just make up a rumor?
