That sounds about right- once you start moving the middle unit is not tracking in line. Try pushing and pulling it side to side when it’s on the ground (and not when the engine is running!).

Possible causes of sideways movement is wear in the oilite bushes on the front pivot of the S-frames, otherwise there may be a fracture in the brackets holding the middle unit to the S-frames. I’ve come across both in my time, but the result is the same- the pulleys run out of line and the belt comes off.

Good luck.
