Does the motor turn in both directions when you power it directly? Believe the symptom on the loose lock ring was motor would run but nothing would happen.

You said the yoke is in the correct orientation. I take it that means the long transverse bar is located at the rear side and short drivers side bar is in front? When you were driving it manually and it stopped was either of the bars touching the center of the assy. If so you might have to back it up to run bars all the way around. Without seeing it that is a hard call from a distance. It is also possible the manual direct driving has moved the cam inside into a position where the limit switch has been depressed and has maybe gotten stuck or damaged. That would explain why it would electrically drive one way and not the other.
