Hello!
I am finishing rebuilding my rear wheel.
Unfortunately I didn't check the individual components before to start.... (Hub faces and drum faces and holes), but mounted all the parts as they were.

I have the following reading now. Are these acceptable?

Side 1:
  • Side movement ( measured on the external diameter - Drum flange) = 18 cent of a mm (7 Thou if I got the conversion right!)
  • Vertical (measured in the internal diameter of the drum) = 7 cent of a mm (2,7 thou)

Side 2:
  • Side movement ( measured on the external diameter - Drum flange) =12 cent of mm (4,7 thou)
  • Vertical (measured in the internal diameter of the drum) = 13 cent of mm (5,1 thou)
  • Chain Sprocket mounded on drum on side 2= 38 cent of a mm (15 thou)
