• Odd. Fulcrum with that preload ring tend to have cartridge bearings, and they disassemble easily enough (usually: use cone spanners on lock nuts, remove preload nut, remove cone/nut with a bearing seat, whack the axle out with a mallet). Keep the old bearings and use them to press in the new bearings, just don’t forget to reinsert axle if it’s a stepped axle fitted between the bearings.

  • I can't see anything out of place.

    The NDS axle looks to have a lip on it to stop it moving right through the bearings but I can't see how the lockring thing comes off (other than by force).

    Oh maybe the NDS side is an axle cap and just pops off. The might explain the lip.
