LH Torque Tube Area
There are various ways to repair the torque tube itself. Barry felt that, in this particular case, the best approach was pretty clear:
With access as good as it'll ever be, the end of the old torque tube was removed, and a replacement piece welded on. As mentioned before, as the rest of the tube is perfect, as it the surrounding metal, a butt weld is perfectly fine here (not to mention pragmatic). The sleeved type repairs definitely have their place, but not needed this time. Later on I'll make you a new torque tube backstop and weld that in. As can be seen, the jig bracket moves very freely.
So far so good...
