"Looking at wobblybobs sectioned picture you have the oil pump drive gears on the bottom of the shaft, the shaft then tapers in a little to a parallel shiney section this is the location of the lower roller bearing. If you follow the shaft up it becomes obscured by the horizontal torque shaft. Just to the right of the torque indicating gubbins where the shaft reappears is a light coloured band on the main shaft running parallel to the torque shaft, this is where the crack occurred. Shaft length reduced by about half. 1/3 of the bearings now not doing anything."
I understand why you think that the shiny parallel section is where a roller bearing sits, but it isn't so. Why it is shiny is beyond me. If you follow the sectioned picture further up the widening conical shaft, it is just possible to see the right-hand end of the welded join above the horizontal torque shaft.
"Slightly better (?) angle of box"
Unfortunately not for this particular debate, but thanks.
