Trying to understand the way the spacers go onto the crank spindle to keep the press in adapter cups from walking out. The instructions seem to point to the drive sure seems to make more sense to have them on the non drive side?

Anyone done this yet?

What stops the crank/spindle assembly when it is inserted? Is it a machined stop on the spindle/drive side bearing interface? I need to look at this more closely. Kinda confusing as it seems the gap on the drive side is too large to fill but on the non-drive side it is much simpler to get the wavy washer and plastic shims correct. If the driveside crank interface is a positive stop and the play is taken up on the non-drive side, then the cups could not back out.
