Rear wheel flange crack

[Burque73]

This has made me take a closer look at the wheels I have here, igoldin74. This '80 850G wheel has that same cracked appearance.

Rotating it around though, I can see indications of it just being a metal plating that's worn or chipped off. There is no crack.

I'm so sorry I didn't simply look at it before.

Say, you mentioned that new spline joint come on the extra wheel you ordered. If so that alone made it worthwile.

Thank you for confirming @Burque73

The hub is pressed into the aluminum wheel, then the wheel and hub turned together. What you see is the mating seam of the two different metals. JMO Was a machinist for 30 years. The second and third picture show the alignment tooth of the hub.
