I had my SBF crank repaired and found an issue. It's on the number three main and only caught it as it rubbed up against the thrust bearing. At first it just felt like a small bump on the other side of the counter weight that took a hit but once I magnified it with the camera found little hair line cracks. Do I need to send it back for repair or can I dress it with a fine tooth file and send it?

I wouldn't use it.
Looks like the crack will need to be ground out and welded back up?
I am sure others will comment.

It sure looks like an impact dent inline with that crack? That journal and thrust face finish doesn’t look good either. I think that crankshaft is fixing to cause you a really big headache.

Good job finding it, I would find another crank.

It's a impact dent from a chunk of rod smashing up against it Ben. They supposedly magnaflux'd the crank and determined it so be usable. Few hundred bucks later and I found this. Cringing at the thought of chucking it after paying for the repairs and to get the rotator balanced but you may be right :(

Go back to the shop that magnafluxed it and have them explain the cracked area?
There is no way that would not show up with magnaflux procedure.
They should re-fix the crankshaft - or tell you it is not fixable and refund your money.

Good luck.
