New crank cracked counterweight
Started measuring bearing clearances for engine assembly and I noticed a crack in my brand new Scat forged crank. Looks that it was caused by the machine shop during balancing and I’d appreciate some opinions on what to do. The hole drilled for balancing seems too close to the edge leaving only a very thin 0.045” piece of the crank in that area which is where it’s cracked through, and even pushed out by the drill bit.
Hard to tell from the pictures, but that line at the bottom is cracked through, and there is lite splintering/star pattern cracking above that line.
Do I need to worry about these cracks spreading? It looks like the beginnings of a worse problem, and this is a turbo build which will see every bit of 800+ Hp.
