Ill give you all some hints
One is new, the other used.
The customer supplied the new one to me (name withheld unless he sticks his hand up)
He noticed it was cracked before he gave it to me.
He returned it to the KTM dealer he purchased it from who told him I cracked it putting it in. (It was in a sealed bag, no thanks to the dealer, they are off my Christmas list!)
Seeing as that was not the case the owner got the dealer to order in another, it was cracked too. And another. All stock in Australia was cracked, 9 bearings.
It was then pronounced “normal” and I just fitted a cracked “stock” bearing. :blink:
