I picked up a used set of HED.3 Spoke Carbon clinchers. While servicing the rear hub I pulled out the non-driveside bearing (little crunchy) and a metal shim sprung out.
My caliper measured the shim at 0.12mm thick and fit between the hub shell and the bearing. I cleaned the hub shell and the bearing then without the shim the bearing just drops in the hub and is loose.
The bearing is labeled 61001 LLB DIN P5 ABEC 5 (measures 28mm, 12mm, 8mm)
The hub shell i.d isn’t perfect round either, measured every 120 degrees, the digital caliper roughly measured 28.1mm, 28.2mm, and 28.3mm.
Am I screwed? Is the wheel salvageable?
How do I press in a replacement bearing into the hub shell with the shim? I have a bearing press and the drifts. Mainly asking about tips when dealing with the shim.
If I shouldn’t use the shim what bearing should I get?
Thanks

0.12mm shim is wildly thick lol. It makes me question if the right bearing size is installed. That would be an incredible amount of bore wear or damage. Though the next bearing size would probably be like 30mm OD without looking up sizes.
You might be able to use a liquid retaining compound to prevent the bearing from shifting. They make different compounds based on the size of the gap they need to fill. The difficulty would be avoiding the bearing being misaligned with the other side when there is that much slop.
