The shop I ran when in the Army had a torque multiplier for working on tanks. It looked like it took two guys to carry it. One of those probably isn't needed for this project.
Ed hit the nail on the head when he recommended using something to hold on to the yoke. I have used a flat bar drilled for the yoke bolts and with a hole for the socket to clear. That and a cheater on the breaker bar should do the trick.
