Torn up wheel bearing dust cover

meb

I tore up a rear wheel bearing dust cover when the cone nut vibrated
loose (or maybe cover vibrated loose tearing up the cone nut surface in
the process). The local bike shops don't carry those covers (I got a
cone nut replacement). Does one need fabricate their own cover to avoid
replacing the entire wheel? Is there some obscure place that sells this
rarely replaced part? If fabrication is the only remedy, how does one
usually fabricate a replacement-bottle cap liner drilled and cut down,
milk jug cap, soda can bottom, or just get another new/used hub and rob
peter to pay paul?

You didn't specify the brand of hub you have, but if it's Campy or Shimano
you can buy the 'small' parts for those hubs.
If you know which hub you have, or if not take the rear wheel to your LBS.
In any case Campy and Shimano hub small parts can be ordered through QBP
(Quality Bike Parts) and aren't terribly expensive, and are easy to get.

One thing I've done is to cover the balls with grease to make
a smooth surface, keeping the hub recess (where the cover sits) dry,
then gently apply silicone RTV (bathtub caulk) to act as a cover.
Works fine, although it has to be redone next time you clean and pack
the bearing.

Try Loose Screws Bicycle Small Parts. Never bought anything from these guys,
but it looks like theyare obscure enougth to have what you want.

Went to five shops, the 3rd had some but in the wrong size, the fifth
had a used one that was the right size they gave me free. It’s is such a
rarely replaced part that it isn’t generally listed as a for sale item
usually you give up and replace or cannibalize another hub/wheel-
preferably discarded if available (one shop that didn’t have any told me
that since it’s not a for sale item, the manufacturer would probably
mail that cover to me free if I called them).

I was considering Epoxy or Silicone as an adhesive rather than a cover
body. Your suggestion got me thinking. If it ever comes up again, what
might work better would be to use a thin disc cut sheet over the
bearings, hole punched for the axle, and then coat the outside of the
sheet with silicone as a dust barrier with the sheet serving as a
temporary barrier to keep the silicone out of the bearings, and then
adhere the silicone disc (cured or curing) to the hub.
