This is repeated until the shaft turns freely, with the correct play.

It reminds me of when I was a poorly paid apprentice, back in the 60's, not
very far from Sheffield.   I spent days at a time doing that. >>

I watched many a millwright spend weeks on end doing the same to the bearings
of steam turbines at electrical generating stations.  A large overhead crane
had to be called upon with each bluing of the bearings.  These hands were not
poorly paid apprentices but, instead, highly paid journeymen touted as
perfectionists.  I do not know the Britspeak term for it but, in our
vernacular, "milking the job" comes to mind.
