I would buy a new one

If it looked good to me and didn't leak I'd run it. Definitely check the mating surfaces on a surface plate though.

I can only guess it's stripped. That's bad news.

The lock washer is peened over one or more of the flat surfaces of the nut to prevent the nut from backing off. I don't know how you would have the nut spinning if you didn't move the lock washer out of the way.
Edit- it says to grind the staked lock nut, not lock washer. I'm beyond the point of experience now and someone else will be able to help you.

Thanks for the pic shep. I was very confused that the manual says to use a drill or grinder. Ill try to knock that dimple out. If the nut still will not come off I guess I will have to cut it off?
I would assume you may have to cut it at this point. Sounds like you may have a new challenge to deal with once you do get it off unfortunately.

I’d put the power tools away (do it by hand) hope that the nut stripped and not the shaft. Possibly and i really don’t want to suggest it but “visegrips” with outward pressure while turning “may” catch but ya i dont really want to suggest that...
At this point drill the nut horizontally with the shaft “not near threads” coal chisel and split it
I’ll be watching good luck
Shep
Wait until tomorrow you’ll have better suggestions
Yeah a die or a thread file would clean that up enough to use
