Add your favorite brand of PENETRATING oil (Not WD-40) and allow it to soak over-night.
Use a spring-loaded center punch and mark the dead center of that broken bolt.
Heat the area surrounding the threads with Map gas until nice and toasty without setting fire to your shop.
Allow it to cool with more PENETRATING oil applied after it no longer bursts into flames.
Drill it out using LEFT-HAND drill bits. Starting with about 1/8" and work your way up in size until it unscrews itself.
Report back on your success.

Is there anything more fun than riding? They are between your legs and are quiet when you turn them off.

Thanks,


So I was curious about the relative depth of the gouges in question. Based on my inexact quick measurement I would say Scottly got this one.
Thank you

I cracked the egg, so to speak. now to get that bolt out, (looks doable) ???.
So I know I said this is a budget build, but.... are crank bearing races available and how much? I'll be looking myself but if you know....
Those bearing shells look almost new?

What is recommended to reseal the case. I noticed there wasn't a gasket there?
