Driveshaft Grinder Damage - Scrap or OK?

[Welsh Pirate]

I'm in the process of refurbishing a driveshaft to fit to my Jag.

I've been removing the centre bearing with a grinder, and have screwed up by cutting slightly too deep



I'd estimate it was 0.5mm deep, and it's where the press fit cartridge bearing sits.

Is this damage terminal? In term of driveshaft balancing, or risk of introducing a stress fracture or some other way? Anyone got an opinion/experience?

3.0 petrol, so not bags of torque/power, if that makes any odds.

Thank you for any advice!

Shouldn't be an issue as there's no movement between that surface and the inner bearing race.

What happens to the vehicle if it fails in service?

Thank you, that's the sort of answer I was hoping for!

I tell my wife that the failure was absolutely nothing to do with my mechanical ineptitude and that these things happen all the time, and it's no reason to get rid of the Jag.

I then refurbish the driveshaft which is currently on the car (which this one will be swapped for), hoping not to mess up the bearing swap when I refurbish that one.

This.

Looks clean no issues.

Lightly file and raised edges if there is any but should be fine otherwise

Thank you all.

I'll carry on as planned then!
