I apologize that I am a bit of a rookie in terms of knowing how my bike works inside and out. With that in mind...

So I picked up one of these old front dynohubs (from e-bay, sigh), but I'm having issues. First of all, after carefully disassembling it for cleaning, I noticed that there are no ball retainers, so I tried my best to just repack the balls (also there were 9 in there, while the schematic says 8 1/4" in a cage). Second, whenever I rotate the axle, the cones tighten/loosen. The bearings on the non-magnet side seem well supported, but the ones on the other seem to easily fall into the middle. Is this tightening caused by the bearings near the magnet side falling into the middle and not providing support against the cap?

Here's a blow-up of my hub, and I apparently don't have the ball cages: http://www.users.globalnet.co.uk/~hadland/sa/sagh6.pdf

Edit: I also noticed that the ringed edge of the cap is not perfectly straight and wobbles slightly like a warped record.

Is this thing a piece of junk, or can it be fixed? Are replacement parts even available?
