Bearing Cap Removal: Caged bearings
Anyone have any ideas on how to remove the dust cap/cover of a vintage schwinn hub? It has caged bearings (not loose). As a result, I can't get the bearings out of the hub as the cap/cover are in the way.

Old school:
Use your Cone Wrench across the dust cap & a Screwdriver, to pry it out ,
try not damage it by bending
fulcrum is your cone wrench edge.. .

A cartridge bearing puller can remove those caps without damage:

How vintage? My 1978 Raleigh Competition G.S. has plastic dust covers in it's hubs. Without a specific model or pic to go by then I'd expect yours like mine, are simply press-fit. So removing the axle makes for much more room to get a wider tool underneath to pop them out without damage. Possible they might be metal and also press-fit. With some hubs you might even use the end of the axle to push on the bearing cage from the other side and push the cover out. But there is some risk of damaging the bearing cage.

The dust cap can be pried with a large screwdriver but measure your force.. just a little bit and circle around. Clean the line between dustcap and hub of any dust or debris to have a chance at removing it.
If the dustcap is not moving and seems it would damage the dust cup if removed, you can reach with a pick or small screwdriver and pop the bearings out of the cages and with some needle nose plies you can twist the cage and remove it that way. Some sidecutters may be useful to cut the cage here and there to remove the cage without forcing other components.
Replace with loose balls anyway - much better - more balls=more force load capability
Here is a video of removing the dustcap (jump to minute 3:00 for the dustcap part )
