Did I kill my hub

[uberchris]

In the process of replacing the rear wheel bearings, I went to cut the inner race off the hubs and got a little greedy. Do I need to replace the hub, or should I just slap new bearings on and send it?

It's probably fine but I'm no expert

Cobra is likely correct, but putting rear bearings in these things is like dying and going to hell. I'd spring for a new hub.

Not an issue as this isn’t a surface the bearing spins on like a crankshaft or something similar.

I’ve accidentally done this on my track car years ago and it never caused an issue after many hours on track. As said above, the wheel bearing is pressed onto the hub as an interference fit and there is not movement between the two.

Ah good to hear. Track abuse is exactly what I was worried about.

Send it.

This would only be an issue if this was the inner race. The concern would be the gash would cause a hot spot and create many issues. There is air which does not transfer heat like the steel.

It still likely causes a hot spot but not to such an extent that it will ever be a problem.
