Accidentally dented the internal shoulder of a Mavic Aksium front hub while removing bearings. Is it salvageable?

Hello everyone,

I'm currently replacing the bearings on my Mavic Aksium Disc front hub and made a rookie mistake.

While trying to punch out the first bearing from the opposite side, my punch tool was misaligned. Instead of hitting the inner ring of the bearing, I ended up hammering against a machined internal shoulder deep inside the aluminum hub shell.

I gouged and dented this internal aluminum shoulder pretty badly. I attached the picture.

Thankfully the bearing sits much closer to the outer edge of the hub, resting on a much shallower lip.

The heavily dented shoulder is further inside the hub "tunnel". The actual bearing seat and its shallow lip seem mostly okay, with only very minor scratches.

My Questions:

1. Since the bearing doesn't press against the deeply damaged internal shoulder, is the hub functionally safe to use?

2. My plan is to carefully file/sand away any protruding aluminum burrs from the damaged area to ensure the actual bearing seat is completely clean and flat. Is this the correct approach?

In the photos, I’ve circled the part of the shoulder where the bearing actually sits. You can see the protrunding burrs here that I want to repair.

1. Should I be worried about micro-fractures in the hub shell from these hammer impacts, or is the aluminum thick enough there to just absorb it as a dent?

I've attached photos showing both the deeply damaged internal shoulder and the actual, shallower bearing seat near the outer edge.

Any objective advice from experienced mechanics would be greatly appreciated. Thanks for the advice!
