Not so much  'How do I?' as 'How do They?'

Prompted by my repairs to the steering ram on my Thwaites 4WD dumper, it prompts me to ask how the female half of a spherical bearing is made, and how do they put them together  :scratch:

Heat the outer race and chill the inner race.  Heat being about 600°F.  Chill being liquid nitrogen.  Then, act speedily.

Manxmodder:
To dismantle turn the inner sphere so the inner and outer bores are at 90 degrees plane from each other and there is usually a pocket or flat on one side of the outer where the inner ball can be extracted/inserted. Much the same way that the bearing insert fits into a pillow block assembly.....OZ.
