You are on the right track, but mine is a bit different. That showed a full length torque tube, my torque tube is only about 30" long, it stops at a frame cross member and is supported there. It then changes to an open drive shaft. My concern is the assembly right at the end of the torque tube where it is supported to the cross member. The order of the assembly of the bearing, seal, and a disc of some kind under the yoke is my concern.
