Those small pegs preventing the crank bearings to turn, is it possible to drill those out?
Currently stuck and too little to grab on to pull those out.

Bluehaze:
Try carbide drill bits.
Or maybe alum?

High Tore EDM or spark erosion  will drill through anything conductive https://www.youtube.com/watch?v=rpHYBz7ToII .

In some engines its possible to drill a small hole to get behind or underneath the bearing peg and move them with a pin punch then close the drilled hole with a weld

Thanks Bluehaze
There are steel seats for the bearings so Alum is not an option.
I have not used carbide drills. Heard those are very britle. Need probably 2.5 or 3mm to drill out those pegs. Was not sure if those actually will drill through the bearing materials. I will try.

EDM seems interesting. Appears to be a project of its own though.
