So searching for BMW M30 mains, I find that it isn’t common to fix them domestically.
Oddly for cheap aluminum bearings I get a hit from Israel made “King” main bearings that seem to offer the dimensions needed. I also see Glycols offered that I suspect are more tradition steel backed design.

Code: Select all

Quantity
1
6
Crankshaft Diameter
59.990 / 59.969mm
59.990 / 59.969mm
Housing Diameter
65.001 / 65.019mm
65.001 / 65.019mm
Max Wall Thickness
2.487mm
2.487mm
Max Length
30.020mm
24.000mm
FL O/S
29.92/29.87mm STD

Neither would drop in especially the thrust, but the non-thrust (6 sets!) show some promise of fitting the air cooled case bore and water cooled crankshaft.
Yeah some may call it overkill, but you can't have too much overkill.

I realize that this maybe clip art or a brand (or reboxer) I have never heard of but I think this is it;

Not sure what to make of the oiling groove, is it normal for cranks held by caps to only oil from the block side?

...They want the higher loaded side fully supported by oil film/max surface area.
I, for one, regularly embrace our new robot overlords, as I am the guy fixing the robots...
