The rotor bearing itself is loosely mounted in the housing and is located in an oil cushion, so it is impossible to assess the clearance without taking it apart, sealing is another matter. The only thing that can be checked on the assembled compressor is, as already mentioned, the lack of axial play and whether it is not radially rubbing against the housing. And further clearance measurements are pure fairy tale, something like tugging at the propeller shaft support and disqualifying the bearing, because the rubber is moving.
With what to the people. What is "loose rotor bearing in housing". You can loosely install bearings (ball bearings, Chinese) to a Chinese mower. Comparing a rotor to an elastic support only shows your little knowledge. Because it's like comparing an elastic joint from a toddler to a properly twisted, efficient double-breasted jacket. Oil pillows and what else? And for that oil pad, what does it do when it starts up and what's worse when it goes out? World power oil hovercraft confidently.
Coming back to the topic, no slack felt with the fingers. Shoulders without any damage visible to the naked eye. Well, we can check how we buy a stimulant.
