generally a hole that catches the edge of the hub shell but lets the bearing pass through is what you would push against..
in the mid 80's, I bought a bare hubshell of that type (A bike shop Garage sale) it is a steel tube , with the alloy spoke flanges added..

sent i to Phil & Co,came back with the axle assembly , in about a week.. Quick turnaround..


there was a kit , a cap to keep a skewer supported 2 prong Freewheel removal tool from slipping out of the notches in the freewheel
and as you unscrewd the freewheel , not press the bearings partially out of the hubshell, in the process..

that may be what the above post was thinking of..

I used Shimano splined freewheels , so never needed that. as the splines did not strip out the freewheel notch or damage the remover
