Ofmega. Hub Cartridge bearing removal
For other cartridge bearing hubs I believe there was a shoulder on the axle top knock out one of the bearings. Then the opposite side could be knocked out.
The axle for the Ofmega is nearly straight, and the very slight shoulder doesn’t look to be used to remove the bearing.
How do I remove these bearings? Maybe a miniature version of a headset tool with four springy spline deals? I could probably cut a piece of copper pipe.
also- are these hubs worth the effort?
still trying to bust the freewheel loose too.
I’m glad I enjoy this hobby 😬
thanks.

The first usual is to insert an appropriate punch like thing into the hub and drive/hammer out the bearing. Generally when doing this stuff on press fitted cartridge bearings with no "spec" tooling replacement of the bearing is suggested. Then the only thing is to figure out how to assemble all w/out harming the bearings. Andy

I use a hollow wall anchor which opens behind the bearing, allowing me to tap it out with a punch.

Those worked fine, though they sometimes had a tendency to close and push through.
I modified a punch by grinding it back on 2 sided leaving a small tab in the.middle. That would fit into the gap and prevent the two sides from closing and fslling through.

Rule number 2 from 10 good rules; Neveer argue with an idiot. People watching may not be able to tell the difference.

If you're going to attempt to overhaul the bearings, don't remove them.
If they bearings are to be replaced, use whatever fits through the holes that you can hit with a hammer. Alternate sides.
No real reason for a specialty tool.

I just had my LBS order a bunch of stuff for a fixed gear bodge-ect that might go to my son to use and abuse.
thanks for the advice everyone!

To remove a seal just stab it with a small sharp thing - dental pick, sewing machine needle - and lift it out. Prying with a screwdriver tends to chew the edge, but a pin prick usually closes up without a trace.
