The cone pulleys were cleaned up, greased and the spindle reassembled.
The next step was to shim the bearings and set the end play. I didn't take any pictures of the new shims but here is one of the old ones. Each shim is the same shape as the cross-section of the bearing.

From memory, the gap between the shim and the journal is for a reason but I cannot remember it right now. I know that I did try using a shim that was rectangular, rather than the cross-section shape and the caps wouldn't seat correctly.
In this picture, I have coloured the shim red and the gap white (front bearing)

Without the shims, the bearing cap will lock the spindle.
I cut new bearings shims and set the bearings to have between .001 and .002 play (front and rear), and set the end play to .001 as outlined in the old South Bend literature (its all I had to work off). I run these with plenty of oil!
