Jon, Thanks for your reply
I annexed the detailed drawings of both heads.
About your 1st remark : No, there are no parts in between the bearings. Confirmed by the picture. What is in the middle is a bracket supporting the Hall transducer, the magnet is stock on the shaft.
As per the Arceurotrade dismounting guide, everything seems to me mounted with a press, which is peculiar for me. I'd agree for both external bearing rings and the chuck side inner one but not for the inner one of the opposite side. Otherwise no preloading would accurately be possible. As far I don't fully understand, I won't force and/or heat the housing to unstick the bearings.
I'm gonna go to youtube as you suggested.

There are several gears and spacers between the 2 bearings that have "STACKED TOGETHER" to create a "SOLID" column of material to be squeezed by the adjusting nut.? You have to thin down one of the spacers due to the different dimensions of the new bearings.

Your wheel bearings do not have a solid spacer between the inner and outer wheel bearings, the lathe does by the accumulation of the 2-speed drive gears and spacers,(do you have a 2-speed lever on the back or direct drive)

Perhaps search YouTube for "mini lathe angular contact bearing" and reveal this -->? ? <--. Maybe 'click it even'. Good luck on your final answers.q
